Alignment by deeds / accession to the RIGI without tax stability of its ownour own interpretation, anchored in the verified facts ↓
Alignment by deeds, and with an asymmetry worth reading in full. Salta acceded to the RIGI through Act 8451 — passed on 29-08-2024, barely two months after the national law — and today has three projects with a published accession resolution: Rincón (Rio Tinto), Diablillos and Sal de Oro II (POSCO). On tax matters it upheld the chain of suspensions that halted the rate cuts committed to in the 2017 Fiscal Consensus: Act 8177 (passed 20-12-2019) suspended nine subsections of its Clause III and ordered the 2019 column of rates to apply for 2020 — it is the first link, read in its verbatim Section 2 — and Acts 8228 and 8314 extended it. The rate that governs mining extraction today, 0.75%, is set by the schedule in force (RG DGR 16/2022); what that chain averted is the programmed cut, not the rate-setting itself. But the accession to the RIGI is TWO sections long: it stabilises no provincial tax, it sets no local-content requirement and it makes no reference to Act 8164 — the province's own law requiring 70% of purchases from local suppliers. In other words: the province joined the national regime without putting up either of the two things an investor would ask of it (stability) or the one a local supplier would ask of it (an enforceable quota).

Salta levies no new taxes on the mine: extraction pays 0.75% turnover tax and, with the exemption certificate of section 174 of the Fiscal Code, 0%. It does tax the supplier: 3.60% with no permanent exemption — a gap of 4.8 times, or of 4 times if the supplier is a small self-employed taxpayer (paying 3.00% under the same code). The nominal royalty is 3% on mine-mouth value, but Act 8164 allows offsetting up to 50% with certificates for works, endorsable and assignable: the effective rate can end up at 1.5%. And here is the difference with the other provinces in the observatory: Salta does have a local-content law — Act 8164 asks for 70% of the annual amount from listed suppliers and 60% of local payroll — but it has to be read in full, because the section says «preferentially» and refers to implementing rules. And its accession to the RIGI is two sections that do not mention it, set no local content and stabilise no provincial tax: the tension between the two rules is legally unresolved.
Fiscal regime & incentives in detail
Turnover tax: Salta's asymmetry runs the opposite way to the intuitive one — the miner can pay 0% while its supplier pays 3.60%. The schedule in force (DGR General Resolution 16/2022, Annex I) sets mining extraction at 0.75%, including code 89120, which textually covers «natural lithium and lithium salts», and exempts it under section 174 of the Fiscal Code (primary production): with the exemption certificate obtained, the mine pays 0%. Code 99000, «Support services for mining, except for oil and natural gas extraction», pays 3.60% with no permanent exemption. The nominal gap is 4.8× and, with the exemption obtained, infinite. That same general rate of 3.60% reaches professional, scientific and technical activities: the engineering firm selling to the mine is taxed like any retailer. verif · 2022 ↗
Mining royalties: Act 8229 (section 9) sets 3% «on the mine-mouth value of the mineral extracted, transported or stockpiled and prior to any transformation process», calculated under national Acts 24,196 and 25,161. But the Mining Promotion Act 8164 (section 13) allows offsetting «up to fifty per cent (50%) of the royalty assessed each quarter» with tax credit certificates for infrastructure works, and those certificates are endorsable and assignable to third parties: the effective royalty can fall to 1.5%. The return is filed quarterly (section 10). Real fiscal weight: mining royalties are irrelevant to the provincial coffers — the 2026 Budget projects ARS 8,842 million prob the figure does not appear in the articles that were opened — it comes from the bill as reported by the press, not from the enacted text, which against projected total spending of the order of ARS 3.9-4.3 trillion works out at around 0.2% estim our own calculation: the ratio is not published by the Budget. Salta does not live off the mining royalty: it lives off employment, off purchases and off the turnover tax of the ecosystem — and that is precisely the argument that underpins its local-content policy. And the number an investor asks for first is not published: the effective rate each project ends up paying after offsetting under section 13 is not published project by project — it is item number one in any tax due diligence in Salta. verif · Jan 6, 2021 ↗
Local content and local employment: Act 8164 is the piece Salta has and the other provinces in the observatory do not. Its section 15 creates the Provincial Registry of Local Suppliers to Mining Companies (RPPLEM), «free of charge and public»; section 17 says that mining companies «shall preferentially contract works, goods, inputs and/or services provided by local suppliers listed in that Registry, in a share of no less than seventy per cent (70%) of the total annual amount contracted»; and section 18 requires them to hire workers domiciled in the mining departments, and then in the rest of Salta, «in a number no lower than sixty per cent (60%) of their entire payroll». To count as a local supplier (section 16) you need an actual or corporate AND tax domicile in Salta, at least 80% of the payroll actually domiciled in the province and 51% or more of the shareholding in the hands of Salta-based partners; for a joint venture, a provincial partner with at least 30%. verif · Oct 22, 2019 ↗
Accession to the RIGI: Act 8451, passed on 29-08-2024, enacted by Decree 588 of 17-09-2024 and published in Official Gazette 21796 of 19-09-2024. It has exactly TWO sections: the first accedes to Title VII of national Act 27,742 and the second notifies the Executive. There is no local-content clause, no provincial tax stability and no reference to Act 8164. It is a threadbare accession: the province joined the national regime without putting up either the stability an investor would ask of it or the enforceable quota a supplier would. Nor was any implementing decree for that accession found. verif · Aug 29, 2024 ↗

Key indicators
SaltaThe three numbers say the same thing from three angles, and what they say is that Salta is not a mining province in the sense that Catamarca or San Juan are: it is a large province with a mining front inside it. It is the country's ninth economy and the most populous of the five the observatory covers, with 1,441,351 inhabitants; its mining is 2.81% of output, twelve places behind retail, and even so it takes 61.4% of what the province exports in the January-April 2026 cumulative figure: the lowest share in the group of mining export provinces, that is, the only case where there is something else on the other side. Inside that front, the mineral that rules today is gold (59.1% of the basket), not lithium (26.7%), even though lithium is growing at 222% year on year. And mining employment —5,569 jobs as of March 2026, third in the country behind Santa Cruz (8,887) and San Juan (5,579)— is large on the national map and small on the Salta map. That combination defines who the client is here: not someone betting that the whole province turns into a mining pipe, but someone who sees three different calendars — gold already exporting, lithium starting up, copper deciding the decade — on top of an economic base that does not depend on any of the three working out.
What cools it downThe copper that has not come in yet and the implementing rules that do not exist. The province's largest capital commitment — Taca Taca, of First Quantum — has no public evidence of a RIGI application filed unconf status of the filing: the official portal does not publish the detail of the projects under evaluation, and until it does the Salta portfolio is lithium and gold, not copper. On the regulatory side, the provincial accession to the RIGI is two sections with no implementing decree and no reference to Act 8164: the tension between the 70% local content the provincial law demands and a national regime that does not mention it is legally unresolved, and whoever comes in as a supplier comes in without knowing which of the two rules will reach them.
2.81%
is mining's weight in Salta's output — and it explains 61.4% of what the province exports (cumulative Jan-Apr 2026)
the full data
The gap between what mining produces and what it exports is the whole province. In 2024 gross value added, metal ore and quarry extraction is 2.81% of gross provincial product and the twelfth sector, behind retail (16.09%), agriculture (11.97%), public education (7.98%), construction (6.15%) and six more. Yet in the January-April 2026 cumulative figure mining accounted for 61.4% of the province's total exports, with USD 274 million placing it fourth in the country by value, behind Santa Cruz (1,293), San Juan (849) and Jujuy (556), and above Catamarca (235). That 61.4% is the LOWEST share among the five mining export provinces — Catamarca 95.9%, San Juan 91.0%, Santa Cruz 88.3%, Jujuy 87.2% — and it is exactly what makes Salta different: it is the first diversified province in the observatory. When the price of lithium or gold moves, there is a cushion here; in Catamarca there is none.
59.1%
of Salta's mining exports is GOLD, not lithium — the province that does not fit the story
the full data
In 2025 Salta exported USD 502,567,944 FOB in mining across 148,968 tonnes, and the mix takes apart the lithium-province story: gold USD 297.2 million = 59.1% (+35.9%), lithium USD 134.3 million = 26.7% (+222.2%), borates USD 64.2 million = 12.8% (+23.8%) and copper 0.8%. It is the country's fourth mining export province with 8.3% of the national total (USD 6,091 million). Within the North-West, Salta concentrates 79.7% of the gold, 97.4% of the copper and 76.9% of the borate, but only 14.4% of the lithium: the region's lithium belongs to Jujuy and Catamarca. Destination matters as much as mineral — the United States takes USD 291.1 million (57.9%) and 94.5% of the metal ores, with China second and growing 905.4% from a small base.
5,569
mining jobs — the country's third province, behind Santa Cruz (8,887) and San Juan (5,579)
the full data
As of March 2026 mining employed 5,569 people in Salta: the country's third province, behind Santa Cruz (8,887) and San Juan (5,579) — the gap with San Juan is just 10 jobs. The three North-West provinces together account for 12,520 workers, 31.2% of national mining employment. Within the North-West, Salta has more mining employment than Jujuy (3,475) and than Catamarca (2,502) taken ONE AT A TIME: added together they come to 5,977 and overtake Salta. Two caveats the record does not hide: Salta is down 5.7% year on year and is the only one of the seven main provinces falling — in the same month Catamarca (+21.9%) and San Juan (+8.4%) grew — and female participation is 18.3% against a national average of 12.8%, peaking at 41.4% in metalliferous mining and exploration. Against a population of 1,441,351, 5,569 jobs are a small number in absolute terms: mining is not yet Salta's employer, and that is why the province's argument with the companies is not the royalty but procurement and jobs.
Investment climate
analyst readingSalta is the first province in the observatory that does not depend on mining, and that is at once its strength and the reason you come in differently.
It is the country's ninth economy, the most populous of the five we cover, with retail and agriculture above mining in output. But its mining front has three strands on three calendars: gold, which already exports and accounts for 59.1% of the mining basket; lithium, which is building and growing at 222% year on year; and the copper of Taca Taca, the province's largest capital commitment, which has yet to file its RIGI application. Three different client bases, not one. What a supplier has to understand before quoting is the tax step, because here it runs the opposite way to the intuitive one: the mine pays 0.75% turnover tax and, with the exemption certificate of section 174 of the Fiscal Code, pays 0%; whoever provides it services pays 3.60% with no permanent exemption. The nominal gap is 4.8 times and, for the exempt miner, infinite — although for a small self-employed taxpayer, who is the one that really comes in through the service gaps, the real gap is 4 times. On the good side, Salta has a piece the other provinces in the observatory do not: Act 8164 creates a provincial registry of local suppliers and asks mining companies to contract at least 70% of their annual amount from those listed, plus 60% of the payroll domiciled in the mining departments.
It has to be read in full, because the section says «preferentially» and refers to implementing rules: it is a soft mandate, not an automatic quota. And its relationship with the RIGI is unresolved — the provincial accession is two sections that mention neither local content nor tax stability. That registry's roll today holds 498 approved suppliers, with 340 registrations in the past two years: it is a market forming right now, not a closed one. To come in you need to be domiciled in Salta with 80% of the payroll provincial and 51% of the shareholding, and the door the rule itself leaves open is a joint venture with a Salta partner at 30%. The last thing worth knowing, and almost nobody attends to it, is that the Salar del Hombre Muerto sits on a disputed boundary: Salta and Catamarca agreed to split the area's taxes and royalties 50/50, and the protocol requires anyone operating there to register in BOTH jurisdictions of the Multilateral Agreement. It is a concrete obligation, little known and poorly attended to.
What to watch
Confidence holds by facing head-on what tests it. The factors to follow closely:
- The environmental permit for Taca Taca, which is the step that unlocks everything else. It is the province's largest capital commitment — USD 5,250 M declared — and the one that decides the decade of Salta copper. The useful reading is not that «it has not filed for the RIGI yet», but that the project has already climbed four steps of a six-step ladder and you can see which one it is on: the consultation with indigenous communities was certified by the Secretariat of Indigenous Affairs in January 2025; the hydrological feasibility certificate was GRANTED by Salta's Secretariat of Water Resources in April 2026 — and it is worth reading with its textual scope: it authorises water for the first stage, not for full capacity; the environmental impact study for the 345 kV line has been filed since September 2025 and is under review; and the mining ESIA is filed and awaiting approval, which the company itself places within 2026 once the public consultation is completed. Only then come the water concession, issued when the ESIA is approved, and the RIGI application, which the company said it will file after both. That is why the event to watch is not the national Official Gazette, which is the last link: it is the approval of the mining ESIA by Salta's environmental authority, which triggers the whole chain. A supplier that wants to be inside when construction starts has its clock right there, and it gives months of notice ahead of the other one. thesis the other data point worth watching in parallel is the operator's balance sheet — net debt of USD 5,407 M as of 30-Jun-2026, practically equal to the capital the project requires — which is the context in which the reported July 2026 process to sell a minority stake is to be understood; reading it as part of the clock is our own interpretation, and the company has declared no cause for any delay.
- The implementing rules for the RIGI accession and the tension with Act 8164. The provincial accession is two sections with no implementing decree, no tax stability and no reference to the local-content law. As long as it stays that way, a supplier registering with the provincial registry does not know whether the 70% of section 17 reaches it inside a RIGI project, and the chambers have already said so publicly. It is settled by a decree or by an act, and both show up in Salta's Official Gazette.
- The boundary with Catamarca in the Salar del Hombre Muerto. The two provinces created interprovincial authorities by law and a 50/50 split of the taxes and royalties of the disputed area, but the ninth clause of the agreement ceases to have effect once Congress settles the boundary: at that point the winning province becomes the sole authority, and whoever structured their operation around the split has to redo it. It is settled outside the province and on a timetable nobody controls.

The largest RIGI application Salta has filed, and the one its portfolio was missing: over USD 3,000 M across three stages on the Pozuelos and Pastos Grandes salt flats, filed on 28 Feb 2026 and still unresolved. Declared capacity at full build-out of the three stages is more than 150,000 tonnes of lithium a year — a figure both sources report without specifying whether it means lithium carbonate equivalent (LCE) or lithium metal, a ~5.3x difference that rules it out for any sizing. It comes from merging the Pozuelos and Pastos Grandes basins into a joint venture between Ganfeng and Lithium Argentina (Aug 2025); as of Jun 2026 the partners were seeking a third investor to finance development.

PPG is not one salar: it is Pozuelos + Pastos Grandes under a single operator, and its technical report is dated 30-Apr-2023, before that consolidation. A three-stage build-out over two aquifers forces a re-signing of the resource. The gap is NOT the metre drilled —AGV Falcon, a Salta firm, already lists Ganfeng among its clients— but the firm that models the aquifer. It deliberately overlaps with the hydrogeology block of the province's drilling niche, which already sizes it: here we state that this project is what triggers it. Media and not alta: CAPEMISA's register lists six geophysics/hydrogeology firms, so «there is no supply» would be false — what is scarce is the signed numerical model.

This is what a foreign supplier chain cannot self-supply: it requires an Argentine licence and a file before the provincial authority. The clock is a rule in force and read in its primary source: article 20 of Law 8164 conditions approval of the first-category environmental and social impact study on a progressive contracting system of between 40% and 70% of total payroll, «according to the stage and scale», and PPG only has the stage-1 permit approved. Media and not alta because the operator itself already reports >80% regional payroll at Mariana: the market is not «help me comply» but «prove it», which is smaller and which so far nobody has bought.

It is the ONLY RIGI project in Salta with a grinding plant: 9,000 t/d (3.15 Mt/year). The copper, gold and silver dossier flags it as an open gap in the province — nobody in Salta currently maintains mills of that class, and the package (relining, liner changes, alignment, vibration analysis, heavy-gauge welding) would today be imported from Chile or San Juan. It is a high-value-per-hour service with a scheduled shutdown window, and whoever gets certified during construction goes on to operate it.

Second stage of POSCO’s Sal de Oro lithium complex in the Salar del Hombre Muerto, on the disputed Salta/Catamarca border strip: it adds a 23,000 t/year lithium carbonate plant to the hydroxide plant opened in Oct-2024 in General Güemes (Salta).

A first-order data point for the satellite-services thesis: the committed supplier development plan is 21.02% of the amount allocated to suppliers, goods and works, and the resolution validates it against the 20% floor of section 47(l) of the annex to decree 749/2024 — the national RIGI regime — not against the 70% of Salta’s Act 8164.

Jurisdiction: Resolution 1157/2026 does not assign a province (it is a federal act), but it confirms the VPU's legal domicile is in Salta capital and that the project sits in the Salta/Catamarca border area of the Salar del Hombre Muerto — consistent with the 'Catamarca-Salta' attribution already carried by the National Mining Secretariat's 2025 Project Portfolio (probable, separate source). We count it once, under Salta, so the amount is not double-counted in the portfolio, with the shared nature declared here. Local content: 21.02% of the total amount to local suppliers. Milestone obligation (art. 3 of the same resolution): in the 1st and 2nd year counted from notification it must certify ≥40% of the minimum investment amount in computable assets; deadline to reach the minimum amount: 31 July 2029. Background found only in the resolution: a first application dated 30-Oct-2024 was WITHDRAWN by Posco on 17-Nov-2025; the approved one is a new filing dated 15-Nov-2025, already under the dedicated-branch VPU. The declared object (carbonate by solar evaporation plus brine treatment with calcium oxide) is destined entirely for export. verif · Jul 31, 2026 ↗

Expansion (Phase 1B) of the historic Fénix lithium-carbonate project in the Salar del Hombre Muerto, operated by Rio Tinto via Minera del Altiplano. It adds 9,500 t/year of capacity (to 38,000 t/year). Phase 1B already reached first production in Q2 2026, ahead of plan, and is still commissioning; the resolution sets >60% of the amount to local suppliers. The schedule the company announced —start toward Jul-2026 and works through Nov-2026— was overtaken by that early start.

Filing statusRIGI accession approved by Resolution 431/2026 (Ministry of Economy). An expansion of a pre-existing project that is not itself an adherent: 'Phase 1B Expansion' — it adds 9,500 t/yr of lithium carbonate (28,500 → 38,000 t/yr). Construction status (Jul 2026): Phase 1B reached first production in the second quarter of 2026, ahead of plan, and remains in commissioning; Rio Tinto describes it as 10,000 t/yr of battery-grade carbonate. In the same salt flat and under the same owner, Sal de Vida (15,000 t/yr, conventional ponds) also reached first production ahead of schedule in Q2 2026. Base caveat: the resolution says 28,500 → 38,000 t/yr and the company says 20 → 30 ktpa from Phase 1A plus 10 ktpa from 1B = 40 ktpa: these are two different accountings of the same asset. verif · Apr 6, 2026 ↗

Opportunities · where you come in · 9 satellite niches
The entry point to the boom: satellite-service niches quantified in USD, with their competitive map, the gap to enter and how demand evolves.
What this menu covers, said head-on: the nine quantified niches are the services economy that sells to the Salta puna — the lithium salars of Los Andes and the hard rock of Diablillos — which is where there is published computation, a legal clock running and derivable prices. Now: demand is up there, and the base you come in from is not always. The two salar departments are tiny — Los Andes 7,182 inhabitants and La Poma 1,789, against 627,704 in the capital (2022 Census, INDEC final results) — so the boom-town pattern is not repeated here. Counting the suppliers already identified across the nine niches, the split is nearly even but it divides by type of business, not down the middle: in the Salta city–General Güemes corridor sit the laboratory, metrology, drilling, chemicals and the railway (SGS and Conhidro in the capital, Transclor and the POSCO plant in Güemes, the C-14 branch line through Rosario de Lerma); up top, in San Antonio de los Cobres, Olacapato and Tolar Grande, sit catering and camps, the local suppliers' chamber, the lime plant and cooperative transport. Both are real doors in and they do not ask for the same thing: the corridor asks for equipment and authorisation, the puna asks for presence and high-altitude logistics. All of them annualise over the same 2026-2029 window, which comes from the investment deadlines of the resolutions already published, and that is why they can be added up and compared with each other. Added together they come to the order of USD 162 to 357 M per year — our own estimate, and it is worth reading with the limit attached: it is the sum of the nine floors against the sum of the nine ceilings, that is, extreme against extreme, and it is not a distribution, because the nine share drivers (the price of lithium appears as a risk in eight of the nine). It is an order of magnitude, not a forecast, and it is not a percentage of capex: it mixes construction demand with recurring operating demand. Copper is not in here, and it is the absence that weighs most: Taca Taca is the project that decides the province's decade — declared capex of USD 5,250 M in its February 2026 technical report — but its application to join the regime has not yet been filed, because the company said it will file after the environmental permit and the water concession (the full ladder, with the milestones already met, is in «What we watch»). With no resolution there is no legal deadline to annualise anything against. Quantifying it today would mean selling a market with no date. The same goes for Pozuelos-Pastos Grandes, filed and unresolved. Both are left declared and not added within each niche, so that nobody loses them or counts them twice: when the resolution comes out, the market that today appears as a ceiling moves into the count.

A perpetual core with a short competitive window. The niche's heart — the quality control of four lithium plants and a gold mine in production — scales with tonnes produced, not with construction capex: when the construction niches switch off in 2029, this one keeps billing every month. The window that does close is the other one: 12 to 24 months until one of the two reference laboratories registers accredited scope for lithium in brines with a site in Salta.

USD 0.4-2.8 M/yearurgent demand
The urgency does not come from volume —it is the smallest market in the province— but from three clocks running at once and none of them waits. The regime of Argentine accredited calibration is being rebuilt since INTI Resolution 198/2025, which declared the Argentine Calibration and Measurement Service dissolved on 1 December 2025, and 58 laboratories have already migrated: the board is reshuffled today and will be settled in a couple of years. The environmental permit of the shared-area project is what turns the obligation to measure into a purchase specification, and it is being decided now. And the agreement that creates that obligation carries its own switch: when Congress settles the boundary between the two provinces, it lapses. Whoever arrives with the technical specification written before it exists defines the tender specification the purchase is later made against.

It is not a window that closes: it is a clock that does not stop. The supplier certificate expires every 2 years and the whole roll rotates, the environmental impact study is accredited at every biennial renewal, the exemption certificate expires and is renewed, and compliance in two jurisdictions is filed every month. That is why it is one of the few markets in the province that does NOT switch off when the construction window ends in 2029. What does have a date is the structuring peak brought by the works starting now, and a concrete tax window for whoever registers: a zero rate for up to twelve months for a new taxpayer, expiring on 31 December 2026 unless extended.

The closest one is not an Argentine rule: it is the four international institutions that financed that project with USD 1,175 M in March 2026 and that audit occupational health and safety. And unlike almost every other service in the province, this one does not switch off in 2029: as long as there are people on a 7 by 7 roster above 3,500 metres, there is fitness, surveillance and transfer.

On top of that two clocks beyond anyone's control are running: the tender for the 91 km of gravel on RN 51 (if it comes late, Chile consolidates the flow through Jama) and the 50-year concession of the C-14 line (if the train scales, it eats the long-distance bulk).

Ecosystem companies · Salta
These companies are the concrete demand a supplier invoices, and it is worth looking at them knowing which of them invoices today: 59.1% of what Salta exports in mining is gold and 26.7% lithium, so the only one already selling metal at scale is Lindero, the open-pit mine Mansfield Minera operates in the Arizaro salar for Canada's Fortuna Mining. It produced 87,489 ounces of gold in 2025 and has guidance of 92,000 to 102,000 for 2026, with 1,091 people working between direct staff and contractors. It is the province's only door that buys operating services for a metal mine rather than for a construction site. On the lithium side, two deliver product with their start-up confirmed in the issuer's own primary source: Eramine, the Argentine subsidiary of France's Eramet, took its first lithium carbonate out of Centenario on 24 December 2024, and Posco Argentina has been operating its hydroxide plant in General Güemes since October 2024. A third, Litio Minera Argentina — of China's Ganfeng — built the perimeter's only lithium chloride plant at Mariana, although the production start-up does not appear confirmed in the issuer's primary source: what was opened is the start of construction. The others are putting in the steel: Rincón Mining, Rio Tinto's vehicle, holds the largest RIGI commitment in Argentine lithium at USD 2,744 M verif Res. 735 in the official gazette; Posco is adding a 23,000 t/year carbonate plant to the one it already runs verif; and AbraSilver closed the Diablillos feasibility study in June 2026, with 25 years of mine life ahead. That mix is what sets Salta apart from a province of promises: there is large construction starting and, at the same time, one mine and two plants already buying maintenance, laboratory and logistics every month. The opportunity map above comes from crossing that demand with what the province still does not know how to supply.
The crackThe way in here is not a reserved quota: it is qualifying. Salta's Act 8164 asks for 70% local content, but a project acceding to the RIGI is measured by the national yardstick — the 20% floor of decree 749/2024 — and there is concrete proof of how much that difference weighs: the supplier development plan Posco committed to is 21.02%, and its resolution validates it against that federal floor, not against the provincial 70%. For anyone wanting in, that orders the strategy: you compete on capability and certification, not on quota. And it is worth starting with the two plants already buying operating services, where the purchase order repeats every month and does not depend on a final investment decision that has not been taken yet.

What it does here
The most advanced silver and gold project in the Salta perimeter: definitive feasibility closed in June 2026 and RIGI accession approved, with a 9,000 t/day tank leaching plant and a projected 25-year mine life.
Production
No production yet: the definitive feasibility study was completed in June 2026. Study plan: a 9,000 t/day tank leaching plant, a 25-year mine life and average annual production of 10 Moz of silver equivalent. Initial capital, from the final investment decision to first production, is USD 721.5 M including contingency.
Reserves
Proven and probable reserves as of 16-May-2026: 77,911 thousand tonnes at average grades of 0.70 g/t gold and 73 g/t silver, equivalent to 183.5 Moz of silver and 1.76 Moz of gold.

Profile
AbraSilver Resource Corp declares 100% of Diablillos, the most advanced silver and gold project in the Salta perimeter: it closed its definitive feasibility study in June 2026 and already has its RIGI accession approved by Resolution 562/2026 of the Ministry of Economy, published in the Official Gazette of 11 May 2026. The holder of that accession is PACIFIC RIM MINING CORPORATION ARGENTINA S.A. (tax ID 30-67305977-1), a corporate name the resolution states and the operator does not mention on its project page; the corporate link between the two could not be opened against a primary source and is therefore not asserted here. Three different amounts coexist for this project, measuring different things and not to be added together: USD 721.5 M of initial capital per the feasibility study, USD 481.7 M of computable assets per the resolution and USD 764 M of total investment per the official RIGI portal. For the services ecosystem it is the client with the most legible calendar in the Salta puna: a project with engineering closed, scale defined at 9,000 t/day and twenty-five years of operation ahead.

Production
In production: first lithium carbonate delivered on 24 December 2024, after construction that began less than three years earlier. Design capacity of 24,000 t/year of battery-grade lithium carbonate. The salar's resources support an option to grow capacity above 75,000 t/year of LCE, with no committed date.
Reserves
Drainable mineral resources of the Centenario-Ratones salar: more than 15 Mt of lithium carbonate equivalent (LCE), with an average brine concentration of 407 mg/L of lithium.
Profile
Eramine is the Argentine subsidiary of the French mining and metals group Eramet, which took 100% on 24 October 2024 by buying out its partner's remaining 49.9%. It operates Centenario-Ratones, the first plant in the world to take Eramet's direct lithium extraction to industrial scale, and delivered its first carbonate on 24 December 2024, less than three years after breaking ground. For the satellite-services thesis it is one of only two doors in the Salta perimeter that already buys OPERATING services rather than construction services: while Rincón builds its large plant and Diablillos starts its engineering, here there is a plant doing maintenance, moving product and contracting laboratory work every month. The salar's resources, of more than 15 Mt of LCE at 407 mg/L, also leave it the option to scale above 75,000 t/year, although the group has committed to no date.

What it does here
The province's only producing metal mine, and the only Salta operation that buys OPERATING services at metal-mine scale rather than construction services: an open-pit mine with heap leaching that produced 87,489 ounces of gold in 2025 and 97,287 in 2024, operating with guidance of 92,000 to 102,000 ounces for 2026. The local vehicle is Mansfield Minera S.A.
Production
87,489 ounces of gold in 2025, against 97,287 in 2024 — 10% less, due to an operational stoppage and not to deposit decline: the HPGR tertiary crusher was out of service for 12 days in December and the primary one had failed in late September. The 2026 guidance rises again, to 92,000-102,000 ounces. A total of 6,471,573 tonnes were stacked on the leach pad at an average grade of 0.58 g/t.
Profile
Lindero is Salta's only producing metal mine, and therefore the province's only door already buying operating services at metal-mine scale — not construction services — every month. It is an open-pit gold mine with heap leaching in the Arizaro salar, some 50 km from Tolar Grande, operated by Mansfield Minera S.A. for Canada's Fortuna Mining Corp. Its product is doré, and that gold is what explains why 59.1% of Salta's mining exports are gold and not lithium: while the perimeter's four lithium projects build or start up, the one invoicing in metal today is this one. For a supplier that changes the conversation: Lindero declares 1,091 people working (683 direct and 408 from contractors, 98% Argentine and 30% from local communities) and USD 106 M of purchases from suppliers in 2025 — a figure the company reports nationally and does not break down by province, so it serves as an order of magnitude for the spillover of a metal mine in steady state, not as the spend that lands in Salta. The asset's limit is not regulatory but geological: what lies ahead is not a stuck permit but reserves that have to be replaced, and the brownfield exploration budget the company announced for 2026 is USD 3.7 M, with some 11,000 metres of drilling in neighbouring Arizaro.

Production
What this seal covers is the OPERATING STATUS, and that is why it goes as probable: there is no primary source declaring the start of production. The issuer published the start of construction — 30 May 2022, with the environmental impact study approved by the province in 2021 — but not a production start-up release.

Profile
Litio Minera Argentina S.A. is the vehicle through which Ganfeng Lithium, owner of 100% of the capital, develops the Mariana project in Salta. It is the only one in the Salta perimeter whose product is neither lithium carbonate nor hydroxide but chloride, and that changes the chain downstream: different logistics, different packaging and a different end customer. The issuer announced an investment of some USD 600 M for a 20,000 t/year base over resources of some 8.12 Mt of LCE, with the environmental impact study approved by the province in 2021, construction starting on 30 May 2022 and more than 1,700 declared local jobs. What this observatory has not yet been able to open against a primary source is the production start date: the operations start-up release is not in the issuer's press room, so the operating status is reported as probable and not as verified.

The only lithium operator in the Salta perimeter that also industrialises outside the salar: its General Güemes hydroxide plant has been operating since October 2024, and the approved second stage adds a 23,000 t/year carbonate plant destined entirely for export. The project vehicle has its registered office in the city of Salta.
Production
Lithium hydroxide plant operating in General Güemes since October 2024. The second stage approved under the RIGI adds a 23,000 t/year lithium carbonate plant by solar evaporation with calcium oxide treatment of the brine, destined entirely for export; the deadline to reach the minimum investment amount is 31 July 2029, with a milestone of at least 40% of the minimum amount within the first two years from notification.
Profile
Posco Argentina SAU SDE (tax ID 30-71922048-3) is the special dedicated branch through which South Korea's POSCO group operates the Sal de Oro complex, and it has its registered office in the city of Salta. Its RIGI accession was approved by Resolution 1157/2026 of the Ministry of Economy, published on 31 July 2026, with USD 207,936,427.20 in computable assets; the path was not direct, because a first application from October 2024 was withdrawn by the company itself in November 2025 and the approved one is a new filing. What sets it apart from the rest of the perimeter is that it does not stop at the salar: the General Güemes hydroxide plant has been operating since October 2024, which means there is industrial demand for services in the valley and not only in the puna. For the satellite-services thesis it also leaves the most concrete evidence this observatory has on how much local purchasing the regime really requires: its supplier development plan is 21.02% and the national resolution validates it against the 20% floor of the federal regime, which is less than a third of the 70% the provincial law demands.

The only lithium operation of a global diversified major in Argentina. The «Rincón 3000» starter plant (3,000 t/year) has been producing since November 2024; the 57,000 t/year expansion takes full capacity to 60,000 t/year, with first production expected in 2028 and a 3-year ramp-up.
Production
In production since November 2024 with the «Rincón 3000» starter plant: 3,000 t/year of battery-grade lithium carbonate, reached 32 months after closing the acquisition of the greenfield project. The approved expansion adds 57,000 t/year up to a full capacity of 60,000 t/year (the RIGI commits 53,000 t/year with declared potential of 60,000): construction from mid-2025, first production expected in 2028 and a 3-year ramp-up.
Profile
Rincón Mining PTY LTD. Argentine Branch (tax ID 30-70708643-9) is the vehicle through which Rio Tinto operates the Salar de Rincón, and it is the largest RIGI commitment in Argentine lithium: USD 2,744 M of total investment, of which USD 2,299 M are computable assets, approved by Resolution 735/2025 of the Ministry of Economy. Rio Tinto reached the salar by buying Rincón Mining — from funds managed by Sentient Equity Partners — in March 2022 for USD 825 M, and thirty-two months later it already had lithium: the 3,000 t/year starter plant has been producing since November 2024. What is being built now is the large plant, with direct extraction by nanofiltration instead of evaporation ponds. For the Salta services ecosystem it is the puna's anchor client: a global major with its own supplier standards, heavy construction under way in the middle of the puna and an operation that consumes services today, not in 2028.

▸RIGI: more time and more sectorsDecree 105/2026in forceNATIONALFeb 19, 2026
What changed
It amends Annex I of Decree 749/2024 (which regulates the RIGI of Law 27.742). It extends by one (1) year the deadline to adhere to the RIGI, counted from July 8, 2026 (new deadline: July 8, 2027). It reconfigures the Oil and Gas subsector with two investment floors: offshore exploration from USD 200,000,000 in eligible assets and new onshore developments from USD 600,000,000. It details the Technology sector, which includes biotechnology, nanotechnology, mobility with new powertrains, energy-transition technologies, the aerospace and satellite industry, the nuclear industry, software, robotics, artificial intelligence and the arms and defense industry.
In force
Signed on February 18, 2026, published in the Official Gazette on February 19, 2026 (notice 338519); it took effect the same day as its publication.
Who it affects
Owners of large investment projects that adhere to the RIGI, in particular in the oil and gas sector (offshore and onshore operators) and the new technology verticals (nuclear, aerospace/satellite, AI, software, biotechnology, defense). It benefits those who had not yet adhered by extending the deadline one more year.
Our reading: The Government not only sustains the RIGI: it expands it. It stretches the adhesion window by a year and lowers to USD 200 million the offshore-exploration threshold, two signals that the regime is State policy and not an experiment (R3 stability). Adding nuclear, aerospace and AI broadens the investment menu beyond classic energy (R4 deregulation). What to watch: that the extension is not a symptom of adhesions taking longer than expected. thesis
Impact on Salta: This is the federal reform that most decides Salta's future, and it has a date: Decree 105/2026 extended the filing deadline to 08-07-2027, and it is the only extension Law 27,742 allows. Taca Taca — USD 5,250 M declared, more than the province's entire approved RIGI portfolio combined (USD 4,055 M across three projects) — has NOT filed an application, and Pozuelos-Pastos Grandes is filed without a Committee decision. Salta's nine quantified niches are annualised over the 2026-2029 window of firm capex, which excludes copper: if copper enters before that date, the services market changes by an order of magnitude; if it does not, the construction demand peak stays capped at lithium and gold. This is a falsifiable prediction with a date, not an expectation. favorable stability → long-term investment thesis
▸Salta ratified first, and its Gazette publishes the annex that Catamarca’s does not: the 50/50 split is there in writingActs 8523 and 8524 (Salta)in forcePROVINCIALJan 9, 2026
What changed
Salta approved by law the two agreements it had signed with Catamarca to operate the mining projects that fall on the territorial strip both provinces dispute: Act 8523 approves the Framework Agreement for the SAL DE ORO project (POSCO Argentina S.A.U.) together with three additional protocols — Interprovincial Management Committee, Mining Royalties and Provincial Taxes — and Act 8524 approves the Mining Project Facilitation and Promotion Agreement signed on 27-03-2025 (the Diablillos one) with four protocols — Determination of the Scope of Application, Interprovincial Management Committee, Mining Royalties and Provincial Taxes.
In force
In force since their publication in the provincial Official Gazette on 09-01-2026.
Who it affects
The operators of the projects on the disputed strip — Sal de Oro (POSCO Argentina S.A.U.) and Diablillos — and every supplier that invoices there. The specific purpose of the Framework Agreement, read in the published annex, is to provide a promotional scheme allowing the provinces to split in equal parts the taxes, royalties and any other levy on minerals extracted in the disputed area, and it establishes that both will benefit in the same proportion from any future national or provincial tax benefit affecting the project. The scope of application is the cadastral overlap area between the two provinces plus an Operations Expansion Zone (ZAO). The agreement expressly states that it implies no waiver or recognition of either party’s territorial rights, and acknowledges that the boundaries of the two jurisdictions are not defined within the area. verif ↗
Our reading: The new fact is not the split — we already knew that from the press — but where it was written down. Catamarca ratified the agreement without publishing its Single Annex, and Salta published its own in full: the same fact that in one province was a journalistic account is, in the other, a legible act of State. For an investor that matters more than the anecdote, because it means the tax rules of the disputed strip can be verified without relying on a third party’s reading. It also confirms the real sequence of the file: Salta ratified on 18-12-2025 and Catamarca on 14-05-2026, five months later. The operational gap it opens is the same one as before and is now better grounded: two tax administrations will validate the same extracted tonne under a half-and-half split, and the agreement divides the revenue without setting the measurement method that produces it. thesis
Impact on Salta: It gives written, published legal certainty to two projects operating over a decades-old border dispute, without making them wait for the boundary to be settled. Investment proceeds under known tax rules. favorable thesis
Splitting in half doubles the auditor without creating the method: two tax authorities verify the same extracted volume. That is a compliance cost for the operator and for its supplier — and concrete demand for whoever can produce a number both administrations will accept. mixed thesis

▸Salta: 70/60 local mining procurementSalta Law 8164 (Official Gazette Oct 22, 2019)in forcePROVINCIAL2019
What changed
Mining companies operating in Salta “shall preferentially contract” works, goods, inputs and services from local suppliers listed in the Registry, in a share of no less than 70% of the total annual amount contracted with all their suppliers (section 17), and shall preferentially hire workers actually domiciled in the mining departments and then in the rest of the province, for no less than 60% of their entire payroll (section 18). It creates the Provincial Registry of Local Suppliers to Mining Companies (section 15). What gives that “preferentially” its teeth are two other sections: section 19 conditions access to the law’s core economic benefit — offsetting infrastructure works against royalties — on complying with and maintaining sections 17 and 18; and section 20 requires, for the authority to approve the Environmental and Social Impact Study of a first-category project, a progressive local-contracting schedule set between 40% and 70%. The benefit at stake is large: up to 50% of the royalty assessed per quarter, collectable in tax credit certificates that are endorsable and assignable to third parties (sections 9 to 13).
In force
In force since 2019 (unlike San Juan's analogous scheme, which as of May 2026 remains a bill).
Who it affects
Mining companies operating in Salta, and supplier SMEs that, to qualify for the quota, must register with the Provincial Registry of Local Suppliers to Mining Companies, which the law creates within the Salta Mining Secretariat, free of charge and public (section 15). Section 16 defines a local supplier with four requirements: (1) establishing and maintaining an actual or corporate AND tax domicile in the province of Salta; (2) at least 80% of its payroll actually domiciled in Salta, with specialised professionals and technicians registered with the corresponding provincial professional association; (3) if a legal entity, being incorporated in Salta and having 51% or more of its shareholding held by partners or shareholders with an actual or corporate domicile in the province; (4) if a joint venture, having at least one Salta-based partner with a minimum 30% interest.
Our reading: The 70/60 local procurement rule turns settling in Salta into a hard entry barrier, though not where it seems: the 70% of section 17 says “preferably”, so it is a preference and not a quota. The teeth are in sections 19 and 20 — without meeting and maintaining local procurement and local employment there is no access to offsetting infrastructure works against royalties, and without certifying the progressive system the environmental impact study is not approved. For the SME that settles and registers, it is a regulatory moat. We read it as governor's policy — provincial protectionism in tension with the national opening —, not as part of the Milei program. thesis

▸Salta cuts the rate 20% for retail and hospitality, and exempts newly registered taxpayers for 12 monthsAct 8496 (Salta)in forcePROVINCIALJul 11, 2025
What changed
It creates a promotional regime that cuts the rates in force of the Tax on Economic Activities — the name Salta gives to Turnover Tax — by 20% for two sectors: Wholesale, Retail and Repairs, and Hotels and Restaurants. It adds an incentive to formalise: a new taxpayer registering voluntarily is exempt from the tax for twelve months from the period of registration (General Regime), or from the provincial component of the Unified Monotax for the same period (Simplified Regime, from 01-01-2026). In parallel it repeals a block of fees and charges under Tax Act 6611 and rewrites section 59 so that the Tax Unit adjusts automatically under National Act 25,917 on fiscal responsibility.
In force
The Title I benefits apply from the moment the Directorate General of Revenue issues implementing rules and run until 31-12-2026, with the Executive empowered to extend them for one year (section 8).
Who it affects
Taxpayers under the General Regime who declared a 2024 taxable base not exceeding 8,250,000 Tax Units and who hold a “No Risk” tax compliance rating from 01-01-2026 (section 2). The rate benefit reaches only retail and hotels and restaurants: mining, mining services, freight transport and construction are NOT covered by the 20% cut. The twelve-month exemption, by contrast, reaches any new taxpayer registering voluntarily, whatever their sector.
Our reading: This is a provincial tax cut in the direction of the national programme, and it is worth reading for what it does rather than for how it is announced. The most powerful part is not the 20% on retail and hospitality — which is narrow and has an expiry date — but the twelve-month exemption for those who register: that targets informality, which is where a northern province has the most to gain, and it lowers the cost of starting up for any new SME, including one looking to enter the mining chain. The flip side for our reader is that the mining services supplier is NOT on the list for the cut: its rate remains whatever Tax Act 6611 and its amendments set. And the rewritten section 59 matters more than it looks: tying the Tax Unit to the framework of Act 25,917 makes indexation automatic — that is, it removes from the annual debate a variable that other provinces negotiate. thesis
Impact on Salta: It lowers the cost of entry for a new SME: twelve months free of the Tax on Economic Activities from registration, with no sector restriction. For the mining satellite ecosystem, which needs new suppliers, it is the section that moves the most. favorable thesis
The 20% cut leaves out mining, mining services, construction and freight transport — precisely the satellite sectors. The tax relief exists, but it does not reach the chain this observatory tracks. mixed thesis

▸Longer trucks: Annex R updated after 30 yearsDecree 689/2026in forceNATIONALJul 31, 2026
What changed
Replaces Annex R of Decree 779/95 in full — the Traffic Law regulation that sets weights and dimensions for freight transport — with a new annex (IF-2026-58308528-APN-SSTAU#MEC), after 30 years without an update. Maximum lengths are set at 19.60 m for a tractor unit with semi-trailer, and the road-train scale at three configurations: B1 23.40 m, B2 26.50 m and B3 31.25 m. The text also includes explicit promotion of dedicated CNG vehicles and pure or hybrid electric vehicles. Article 2 delegates to the Transport Secretariat the power to keep updating the annex as technology evolves, so that the next revision no longer requires a decree. One antecedent worth keeping in mind so as not to read too much into it: road trains do not start here — in August 2025 the government had already widened their circulation across the road network, and 75-tonne units have been running since then. What 2026 rewrites is the catalogue of configurations and their dimensions, not the permission for them to run.
In force
In force since 31/07/2026: the decree states that it «shall enter into force on the day of its publication in the OFFICIAL GAZETTE».
Who it affects
Anyone moving heavy freight by road, which across the observatory's five provinces is almost everyone: frac sand and tubulars towards Vaca Muerta, reagents and supplies up to the puna salt flats, ore and concentrate down to the ports. Also hauliers and the workshops that build and adapt equipment, because an approved configuration determines which fleet gets bought.
Our reading: Road trains were already running: what changes here is the entire catalogue of configurations and dimensions, frozen since 1995, and the fact that from now on the Transport Secretariat updates it without needing a decree. This is deregulation in its purest form (R4): it cuts freight costs, which are among the heaviest lines in the accounts of a satellite supplier based far from its customer, and it counts most where there is no rail — the road to Añelo, the approaches to the puna, the corridor to Punta Colorada. thesis
Impact on Salta: Reagents and supplies for the salt flats climb to the puna by road from a long way off, and freight is a high share of the delivered cost. The real effect depends on which mountain routes the province approves for each road-train class. mixed opening and deregulation thesis

▸Mining: imports by sworn statement and declarative fiscal stabilityDecree 482/2026 (Official Gazette Jun 23, 2026)in forceNATIONALJun 23, 2026
What changed
Decree 482/2026 entirely replaces the Annex of Decree 2686/1993 (the regulation of Law 24,196 on Mining Investments) without changing the law. Three substantive changes: (1) imports of capital goods under sec. 21 move from prior authorization/certificate by the enforcement authority to a SWORN DECLARATION of the good's mining destination, integrated into the National Single Window for Foreign Trade (VUCEA) with automatic validation via the Malvina IT System (SIM); (2) fiscal stability (30 years) becomes DECLARATIVE and its start date is set at the filing of the feasibility study; (3) the regional integration of the production chain (deposits and beneficiation plants) is redefined, extending its distance limit TO 500 km — 500 km is the new limit, the endpoint of the extension.
Who it affects
Mining companies with projects under the Law 24.196 regime (lithium, copper, gold, silver) and their capital-goods importers; customs brokers; the enforcement authority (Mining Secretariat). Direct impact in the mining provinces (San Juan, Catamarca, Salta, Jujuy) where the large copper and lithium projects are concentrated.
Our reading: A substantive deregulation of the mining regime that had gone 30+ years without updating: it lowers the friction to import equipment (sworn statement instead of prior authorization) and gives declarative fiscal predictability (30 years from feasibility). It complements the RIGI for the large projects (Vicuña/San Juan, NOA lithium) and reduces the entry cost for the mining-services ecosystem. Aligned with the course: less permit window, more sworn statement + automatic validation. thesis
Impact on Salta: The three Salta projects already approved under RIGI — Rincón (Rio Tinto), Sal de Oro II (POSCO) and Diablillos (AbraSilver) — are in construction or pre-construction, which is precisely the stage that imports capital goods: the sworn declaration replaces the prior procedure and brings equipment forward. But what weighs most here is fiscal stability declared from FEASIBILITY rather than from the resolution, because it reaches the two projects currently outside the regime that concentrate the province's upside: Taca Taca (USD 5,250 M declared in its February 2026 technical report, with no application filed) and Pozuelos-Pastos Grandes (filed and awaiting the Committee's decision). For satellite suppliers the effect is one of timing: it pulls forward the purchasing curve of those already in, and sets a floor of predictability for those still out. favorable opening and deregulation thesis

▸Mining: faster VAT refunds on investmentJoint Gen. Res. ARCA-Mining Secretariat 5878/2026 (Official Gazette, Jul 23, 2026)in forceNATIONALJul 23, 2026
What changed
ARCA (formerly AFIP) and the Mining Secretariat jointly repeal Joint General Resolution 1,641 (ex AFIP) and Resolution 11/2004 of the Mining Secretariat, which until now governed the procedure for refunding VAT tax credits on mining investments (art. 22 of Law 24,196 and Law 25,429). In their place, each agency will issue its own implementing rules for the aspects of the regime under its purview (ARCA on tax/customs matters, Mining on sector matters), with the declared goal of simplifying the application procedure and shortening processing times. Applications already filed under the previous rules continue through the 'VAT Recovery - Special Regimes v2.0' system until they are migrated to the new scheme.
In force
Published and in force since 07/23/2026 (Official Gazette), with a transition period for VAT refund applications already initiated under the previous regime.
Who it affects
Mining companies with projects under Law 24,196 (lithium, copper, gold, silver) that recover VAT tax credits on their investments — it shortens the time between investing (paying VAT on inputs/equipment) and recovering that credit, a real financial cost in capital-intensive projects with long maturation periods. Direct impact on the mining provinces (San Juan, Catamarca, Salta, Jujuy) where the large copper and lithium projects are concentrated.
Our reading: This is the complementary regulation that Decree 482/2026 had announced — and it confirms the decree's thesis rather than diluting it: less red tape, faster processing. Speeding up the refund of invested VAT lowers the financial cost of building a mine before producing a single gram, exactly the kind of friction a capital-intensive investor measures before committing to a project (R4 · opening and deregulation). thesis
Impact on Salta: Salta sits exactly in the stage this rule relieves: its three approved projects (USD 4,055 M) are in construction or pre-production, meaning they pay VAT on equipment and inputs without yet generating the output tax to credit it against. Accelerated refunds free up working capital precisely within the 2026-2029 window over which the province's nine service niches are annualised. It is the same mechanism already stated for San Juan, except that in Salta the capex is lithium and gold rather than copper. favorable opening and deregulation thesis
▸Glaciers: protection by water function and evaluation in provincial handsLaw 27.804 (Official Gazette Apr 24, 2026)in forceNATIONALApr 24, 2026
What changed
Law 27.804 rewrites the heart of the Glaciers Law 26.639: (1) the object is narrowed to protecting glaciers and periglacial landforms INSOFAR AS they fulfill a water function (strategic water reserves / basin recharge), with interpretation expressly tied to arts. 41 and 124 of the Constitution (original provincial ownership of resources); (2) the prohibitions of art. 6 —including mining and hydrocarbon exploration and exploitation— stop being general: they apply only to the glaciers IDENTIFIED by each jurisdiction's authority and only against activities that RELEVANTLY alter (art. 27, General Environment Law) their condition or water functions; (3) it is the provincial authority that determines, via case-by-case environmental impact assessment, which activities imply relevant alteration and which can be authorized; (4) precautionary principle (new art. 3 bis): what is inventoried stays protected until technical-scientific studies verify it does not fulfill a water function — and then it leaves the scope of the law and the IANIGLA Inventory.
In force
In force since early May 2026 (general Civil Code term: the eighth day from the Apr 24, 2026 publication; the law sets no own validity clause).
Who it affects
Mining companies (copper, lithium, gold, silver) and hydrocarbon companies with projects in mountain zones of glaciers/periglacial environment; the provincial environmental authorities (which come to identify the protected object and to decide via environmental impact assessment); the IANIGLA (National Glacier Inventory, now an unavoidable reference but with the removal of landforms without a water function). Provinces with the mining mountain range —San Juan, Mendoza, Catamarca, Salta, Jujuy— are the substantive addressees.
Our reading: The regulatory key of large-scale mining in the mountains: the general prohibition that froze projects through an extensive interpretation of the 'periglacial environment' is replaced by a decidable rule — proven water function + case-by-case impact assessment in the hands of the province that owns the resource (art. 124 Constitution). With the RIGI and Decree 482/2026 (mining regime) already operational, it unlocks the MINING strand of the program: San Juan and Mendoza copper stops having an indefinite environmental veto and moves to a procedure with rules. thesis
Impact on Salta: Salta is one of the five provinces the rule itself identifies as its underlying targets, because of its mining cordillera. The substantive change — defining the protected object by hydrological function, and putting the PROVINCIAL environmental authority in charge of identifying it — returns to the province the decision over the Puna's periglacial environment, where the lithium salt flats and the two highest-capex cordilleran projects (Taca Taca and Diablillos) are located. What is NOT measured here, and is declared as such: how much of the Salta projects' footprint actually falls within periglacial environment under the new criterion. Without that inventory, the effect is legal certainty over permitting, not the opening of new ground. favorable cheaper to meet the demand thesis

PENDINGclosing of the RIGI accession window (08-07-2027) with the province's largest project yet to file an application2026-02-19 ↗
Decree 105/2026 extended the deadline to file RIGI accession applications to 08-07-2027, and it is the only extension Act 27,742 allows. Taca Taca (First Quantum), the largest capital commitment in the province at USD 5,250 M announced — more than Salta's entire approved RIGI portfolio put together, which is USD 4,055 M across three projects — has no application filed to date. The same goes for Pozuelos–Pastos Grandes, filed and still without a decision from the Committee.
Our reading — If Taca Taca files and the Committee rules, the scale of the Salta Puna services ecosystem changes order of magnitude: the nine quantified niches annualise today over the 2026-2029 window of capex ring A, which does NOT include copper. If it does not file before 08-07-2027, the ecosystem's largest upside loses its tax vehicle and its date, and the construction demand peak stays confined to lithium and gold. Vector to watch: the official RIGI portal and the national Official Gazette (applications filed and Committee resolutions). the RIGI promise is kept + stability → long-term investment unconf
PENDINGpending settlement of the Salta-Catamarca interprovincial boundary in Congress, which extinguishes the 50/50 split of the Hombre Muerto2026-01-01 ↗
The Framework Agreement between Salta and Catamarca splits in half the taxes and royalties of the Salar del Hombre Muerto area, whose interprovincial boundaries are NOT defined, and requires anyone operating there to register in BOTH jurisdictions of the Multilateral Agreement. Its ninth clause establishes that the 50/50 split «shall cease to have effect» once the NATIONAL CONGRESS settles the boundary, at which point the winning province becomes the sole authority. It reaches Sal de Oro (POSCO Argentina S.A.U.) and Diablillos, and every supplier that invoices in the strip.
Our reading — A ruling by Congress extinguishes the regime of Protocol No. 2 and with it an entire block of the metrology and traceability and the compliance and local content niches: the supplier stops invoicing the reconciliation between two tax authorities and moves to a single client. As long as there is no act, dual registration remains mandatory and the gap for independent measurement stays open. Vector to watch: boundary bills in Congress, minutes of the bi-provincial management committee and the official gazettes of both provinces. federal-provincial tension + confirms the course unconf
PENDINGpending implementing rules for the provincial accession to the RIGI and how it articulates with the local-content requirement of Act 81642024-09-17 ↗
Salta's accession to the RIGI is Act 8451, passed on 29-08-2024 and enacted by Decree 588 of 17-09-2024. It is TWO SECTIONS long: they accede to Title VII of Act 27,742 and empower the Executive. It has NO implementing decree, it stabilises NO provincial tax and it makes NO reference to Act 8164 on local content, which requires companies to contract «preferentially» a share of no less than 70% of the annual amount from suppliers listed in the RPPLEM and 60% of the payroll from workers domiciled in the mining departments. Neither rule mentions the other: a registered supplier does not know whether the 70% of section 17 reaches it inside a project admitted to the RIGI.
Our reading — The implementing decree — or the act that corrects the accession — is THE document to read in order to size the floor of captive demand for the Salta supplier. If it implements the regime by referring to Act 8164, the 70% becomes enforceable inside RIGI projects and the TAM for local-content certification and auditing has a contour; if it implements it without mentioning Act 8164, or if it is never implemented, local content remains a declaratory preference and that TAM rests only on each operator's voluntary procurement policy. Vector to watch: Salta's Official Gazette (Executive decrees) and statements from the supplier chambers. federal-provincial tension + cheaper to meet the demand unconf

Substitution of federal financing: works migrate from discretionary transfer to sub-sovereign credit and private concession2/3 solid pieces · under waythesis lowers country risk + stability → long-term investment
There are public works even with the chainsaw, through THREE non-federal channels: the province finances with multilaterals (Neuquén: CAF USD 250 M road plan + USD 137.8 M power), taps the international capital market (USD 500 M bond at 7.65%, first placement since 2017) and the private sector takes concessions with no state contribution (Federal Concessions Network II-A signed: 1,871 km for 20 years; II-B >2,500 km under tender). The road-works niche changes client and risk: it stops depending on the federal budget and starts depending on multilateral disbursement, the capital market and the financial close of concessions.

Alto Neuquén road works: USD 250M CAF loan enacted in forceThe materialized case of the sub-sovereign channel: Neuquén enacted laws 3567+3568 and takes USD 387 M from CAF for road and electrical works.
Signal Provincia del Neuquén (colocación internacional de deuda) · 2026-07-23 The third non-federal channel, materialized: a USD 500 M international bond at 7.65% with no royalties pledged — Neuquén's first international placement since 2017.
National routes: to the private sector by toll in executionThe 100% private route: RFC II-A signed (1,871 km for 20 years, no state contribution) + II-B under tender.
Payment to holdouts: closing the 2001-default lawsuits in forceThe closing of the last front of the 2001 default by law: the normalization that enables the credit channel.
Country risk / cost of capital reinforcementThe sovereign ceiling in retreat: country risk at an 8-year low = a lower prime floor for the sub-sovereign debtor.
Public road works and toll road concessions reinforcementThe niche the theory reframes: it changes client (multilateral/concessionaire instead of the federal budget) and risk (execution, not legislative).
High-altitude logistics and export dispatch via the Paso de Sico (Salta) The second instance of the same channel, in a different province: Salta's Law 8506 authorises a FONPLATA loan of up to USD 100 M over 20 years, with 5.5 years of grace and SOFR + 233 bp, secured against federal revenue-sharing, earmarked for road works among other uses. It is the same move as Neuquén's CAF loan and confirms this is not an exception available only to a hydrocarbon-rich province: the gravel road of the Sico corridor — 143 km, of which 91 are still to be tendered — is the use that trade press attributes to that disbursement: the act earmarks the money by category (roads, water and sanitation, border-control technology) and does not name the works. For a supplier the clock on the works moves out of the Casa Rosada all the same: it sits with the multilateral lender and the provincial tender.
Trigger: Two facts that today live on opposite sides of the board are the same process: non-automatic transfers to provinces collapse (ATN in June, the worst since 2005) as the arithmetic flip side of the surplus, WHILE sovereign credit normalization (holdouts closed by law, World Bank guarantees, country risk at an 8-year low) reopens the channel that was blocked: sub-sovereign and project credit.
Mechanism: R1 + R6 + R3. The 'sovereign ceiling' (standard credit theory) left provinces and private players without financing while the sovereign was broken; with the sovereign premium compressed, the premium floor of every Argentine debtor falls and the alternative channel opens. The tension over transfers and its escape valve are the same phenomenon. lowers country risk + stability → long-term investment
The chain, link by link
- 1The fiscal anchor is sustained by cutting discretionary spending to provinces: non-automatic transfers collapse (June ATN −87.7% real, the worst June since 2005). The historical channel of provincial works financing —the discretionary federal purse— closes structurally, not cyclically.consistentMechanism: R1 (zero deficit as the mother of all anchors: the surplus IS the cut in discretionary spending; the withdrawal of transfers is its arithmetic flip side, not an accident).
- 2Simultaneously, sovereign credit normalization reopens the alternative channel: 2001-default holdouts settled by law (Law 27,818, Official Gazette Jul-01), World Bank guarantees (IBRD PBG + MIGA to refinance at market rates; the IDB tranche is NOT yet granted) and country risk at an 8-year low. The sovereign ceiling stops blocking sub-sovereign borrowing: provinces and private players can raise financing where they previously could not. Materialized cases: Neuquén passed laws 3567+3568 and takes CAF credit for USD 387 M; and on Jul-22-2026 it placed a USD 500 M international bond at 7.65% senior unsecured —the province's first international placement since 2017, ~180 bp cheaper than Chubut and with no royalties pledged—: the strongest confirmation of this link, the voluntary market open to the sub-sovereign.provenMechanism: R1 (lower sovereign premium → lower premium floor for every Argentine debtor, provinces included) + R6 (the upgrades-guarantees-program sequence as the signal that validates the channel).
- 3Works get executed through both non-federal lanes at once: the province with multilateral credit (Neuquén: USD 250 M road plan + USD 137.8 M electric) and the 100% private concessionaire with no state contribution (RFC Stage II-A signed by Res 706/2026: 1,871 km for 20 years; II-B >2,500 km in tender, not awarded). For the observatory: the public road-works niche changes client and risk — residual risk is execution/tendering, not legislative; and the tension with governors decompresses via the credit channel, not by reopening the federal purse.provenMechanism: R3 (credible long contracts → private capital for 20 years) + R1 via link 2 (sub-sovereign credit only exists because the sovereign normalized).
Also impacts: Public road works and toll road concessions
What we watch (observable data + external vector):
- That the multilateral channel does not disburse: an unmet CAF/IBRD disbursement schedule. Vector: loan contracts and provincial budget execution, observable.
- That the RFC II-B tender ends deserted or without financial close — private appetite for Argentine brownfield roads is a hypothesis until it closes. Vector: award resolution in the Official Gazette, observable.
- Country risk sustained back above ~800 bps, reactivating the sovereign ceiling and cutting sub-sovereign credit. Vector: market, observable daily.
Predictions we commit to
- pending Neuquén's CAF road plan moves from law to execution: first recorded disbursement and/or tenders for provincial routes 6/21/38/57 published during 2026. how we check: Provincial budget execution + Neuquén Official Gazette (calls for tender); quarterly check. Note 2026-07-24: CAF's board approved both loans (USD 387.8 M, Jul-22; executing agency UPEFE) prob press release not indexed — the announcement→law→multilateral-approval cycle closed in 5 weeks and advances the link, but the prediction requires disbursement and/or tenders: approval ≠ disbursement, still PENDING.
- met RFC Stage II-B (>2,500 km) is awarded with private financial close (appetite for Argentine brownfield roads is confirmed). how we check: Award resolution in the national Official Bulletin; horizon 2026-2027.
Competitive federalism: with no discretionary federal purse and no tax possible on RIGI projects, governors compete for business location — provincial risk flips into a tailwind4/4 solid pieces · ready to executethesis lowers country risk + federal-provincial tension + the RIGI promise is kept
The classic risk 'the province captures your rent' (R7 · federal-provincial tension) mutates into a structural tailwind: Río Negro adhered to RIMI unanimously with a single-window process (Law 5857) and 6 RIGI mining projects landed across 5 provinces that competed to host them. For the investor, provincial adhesion legislation (RIGI/RIMI + single-window + stacked exemptions) becomes a leading indicator of where the next capital lands.
New thesis (Jul 15, 2026), active: two of its three links rest on rules read in the official source — the RIGI sec. 165 shield and Río Negro's unanimous adhesion to RIMI —; the federal transfers datum (ATN) comes from a think-tank report prob. Its predictions are recorded below: if they fail, the thesis gets downgraded right here.

The pieces that converge, the chain and what we watch
Río Negro adheres to the RIMI: national benefit + provincial promotion in a single filing in forceThe case that debuts the pattern: Río Negro adheres to RIMI unanimously with a single window (Law 5857) — a non-aligned province lowering the cost of entry instead of capturing rent.
Ley Bases: the RIGI is born in forceThe lock that closes the capture route: RIGI's sec. 165 shields adhered projects from new provincial taxes (Río Negro's attempt to tax exports was struck down through it in 2025).
Los Azules — copper cathodes (McEwen Copper) approvedThe mining wave as evidence of competition to host: 6 RIGI copper and lithium projects landed across 5 provinces — Los Azules (San Juan, USD 2,672 M) is the first verified in the Official Gazette.
Fiscal anchor reinforcementThe surplus whose arithmetic flip side is the drought of discretionary transfers: without a sustained chainsaw there is no change of incentives.
Investment (RIGI) reinforcementThe board where the result is read: the project pipeline is no longer energy-only — a portfolio diversified by sector and province is the competition at work.
Salta: 70/60 local mining procurement in forceSalta shows the other half of the competition for investment — the half that does not appear in the capital ranking: it joined the RIGI through Law 8451 in August 2024 while keeping its own Law 8164 on local procurement and mining employment. This is the move available to a governor who can no longer capture rent and does not want to give it away either: instead of taxing a project shielded by article 165, it sets local-purchase conditions downstream. With three approved mining projects worth USD 4,055 M — plus Pozuelos-Pastos Grandes, over USD 3,000 M, filed on 28 Feb 2026 and still awaiting a ruling from the Committee — Salta runs in the pack rather than at the front: San Juan holds more than triple its approved mining capital (USD 13,328 M across four projects). That is exactly why it is the case that shows the remaining tool is local procurement, not taxation.
Trigger: Two simultaneous closures change the board for the 24 governors: the discretionary federal purse shut down as the arithmetic flip side of the fiscal surplus (June ATN transfers, the worst since 2005) and RIGI's sec. 165 shields adhered projects from new provincial taxes (Río Negro's attempt to tax exports was already struck down in 2025).
Mechanism: R1 + R7 inverted + R2. With no transfer to ask for and no new rent to capture, the margin left for a province to sustain its economy is attracting investment to its territory: competition among jurisdictions shifts from the war over rent to the war over location — lowering the cost of entry instead of raising it. lowers country risk + federal-provincial tension + the RIGI promise is kept
The chain, link by link
- 1The provinces' historical channel of political financing —the discretionary federal transfer— closed structurally as the flip side of the surplus (June ATN −87.7% real, the worst since 2005). The governor loses the instrument with which he sustained his economy without depending on private investment in his territory.consistentMechanism: R1 (the surplus IS the cut in discretionary spending; the withdrawal of transfers is its arithmetic flip side, not an accident) — same link as tes-sustitucion-financiamiento-federal, read here from the side of the governor's INCENTIVES, not of works financing.
- 2With the second channel also barred —RIGI's art. 165 shields the SPV against new provincial taxes; Río Negro's Feb-2025 'export royalty' attempt was struck down that way—, the governor's only margin is to compete for investment by lowering the cost of entry. The July-15 batch shows it operating simultaneously and across jurisdictions: Río Negro adhered to RIMI by UNANIMITY with a single-window procedure and its own stacked exemptions (Law 5857), and 6 mining RIGI projects landed across 5 provinces (San Juan, Mendoza, Salta, Jujuy, Catamarca) that competed to host them instead of taxing them.provenMechanism: R7 inverted (the tension over rent mutates into inter-provincial competition for investment: same actor, incentive flipped) + R2 (each provincial adhesion completes the federal regime's legal-certainty promise in its territory).
- 3Operational corollary: as long as the federal fiscal regime holds, the watch condition «governors' tension over rent» has a structural bias in its favor (not isolated cases but an equilibrium of incentives), and provincial adhesion legislation becomes a LEADING INDICATOR of where the next capital lands — a new observable to order the federal map and choose the observatory's next province.pendingMechanism: Synthesis R1 → R7 inverted → R2: no single rule describes the incentive-regime change or its methodological consequence (reading provincial adhesions as a predictor).
What we watch (observable data + external vector):
- A province with RIGI or RIMI projects under way raising royalties, gross-receipts tax or mandatory carry on the sector in its annual tax law. Vector: 2027 provincial tax laws in the Official Gazettes, observable — the exact signal of the governors-rent watch condition.
- Governors, via Congress, forcing over the veto the reopening of discretionary transfers or an automatic ATN revenue-sharing law: it would reopen the old channel and dismantle the incentive to compete. Vector: parliamentary proceedings, observable.
- Provincial legislature turnover in 2027 repealing or conditioning current RIGI/RIMI adhesions. Vector: provincial Official Gazettes, observable.
Predictions we commit to
- pending At least one more province adheres to RIMI (or enacts an equivalent single-window RIGI/RIMI adhesion process) before Mar-2027. how we check: Provincial Official Gazettes + the legislation monitoring register; re-checked periodically.
- pending No province with RIGI projects under way raises royalties, gross-receipts tax or mandatory carry on the sector in its 2027 tax law. how we check: Provincial 2027 tax laws (passed Nov-Dec 2026) in the provincial Official Gazettes; this is the exact vector of the watch condition «governors' tension over rent».
