Pro-mining cooperation / own agendaour own interpretation, anchored in the verified facts ↓
Pro-mining cooperation with the national investment agenda, with an agenda of its own in parallel thesis. San Juan joined the RIGI through Ley 2671-I, passed on 15-Aug-2024 verif. It has four mining projects approved under the regime: Los Azules, Gualcamayo, Veladero phases 8 and 9 and Vicuña, the last one as a long-term strategic export project, with Resolución 1154/2026 published in the Official Gazette on 30-Jul-2026 verif. In parallel, the province passed Ley 2827-M on Local Mining Development on 02-Jul-2026, with 80% local employment and 60% local purchases as targets for each project prob. After the second quarter of 2026 it closed a provincial agreement with Vicuña: long-term royalty stability, an infrastructure trust of 1.5% of gross revenue over the life of the mine and a USD 250 M advance scheduled for the fourth quarter of 2026 prob.

San Juan levies no new taxes on the mine: it charges 3% royalties on mine-mouth value (Ley provincial 716-M, within the framework of Ley nacional 24.196) and negotiates per-project agreements —the provincial agreement it signed with Vicuña adds royalty stability, an infrastructure trust and a USD 250 M advance—. What the province does impose is local content: 80% of jobs and 60% of purchases from San Juan as targets for each project (Local Mining Development Law, passed Jul-2026; regulations and RE.PRO.MIN promised before the end of 2026).
Fiscal regime & incentives in detail
Mining royalties: 3% of the mine-mouth value of the mineral (Ley provincial 716-M, art. 8), within the framework of Ley nacional 24.196 on Mining Investment, with 30-year fiscal stability. Collection Jan-May 2025: USD 20.9 M on gold and silver exports of USD 697.3 M. 2025 distribution: provincial Treasury 55%, producing municipality (Iglesia) 33%, Ministry of Mining 12%. That is the split governing Veladero, whose exploitation DIA predates 29-Nov-2007; projects with a DIA after that date split 70/20/10 and the department receives 20%, not 33% (ley 716-M art. 17, see the dedicated entry in this same block). Cumulative 2005-2025: USD 594.1 M, according to a calculation by a private group cited in the press. The provincial agreement signed with Vicuña after the second quarter of 2026 adds a long-term royalty stability framework for that project. prob May 2025 ↗
RIGI accession: Ley provincial 2671-I, passed on 15-Aug-2024 by 21 votes to 14 verif. It was enacted on 19-Aug-2024 and published in the Official Gazette on 22-Aug-2024 unconf. verif Aug 15, 2024 ↗
Turnover tax exemption for primary production based in the province. It is granted by article 120 subsection 16 of the Tax Code (Ley 151-I, as worded by Ley 2802-I of December 2025): it exempts primary production activities from the tax when the revenue originates in the sale of goods produced at the taxpayer's own operations, in activity, located in San Juan. The condition is being current: having paid, by the date set by the provincial revenue agency (Dirección General de Rentas), the Real Estate Tax and the Vehicle Registration Tax due as of 31 December of the immediately preceding year, on the taxpayer's own real estate and vehicles (the requirement does not apply to farmers with up to 30 cultivated hectares). Article 49 of the Tax Law expressly excepts it from the 0.75% primary production rate, and the exemption does not reach taxpayers enrolled in the Provincial Simplified Regime verif. It is the largest fiscal lever the province holds over extractive activity: it is what makes mining based in San Juan pay not the 0.75% of primary production but nothing at all thesis. verif Dec 23, 2025 ↗
Mining Activity Promotion and Development Regime (Ley provincial 1723-M, 2018): total exemption from provincial taxes for mineral exploration activities — turnover tax, Real Estate Tax on assets tied to the activity, Vehicle Tax on vehicles assigned to it, and elimination of Stamp Tax on every directly related contract — plus refundable contributions equal to the exploration VAT credit until the federal government restores it. For the following stages, up to the start of production, the exemptions are PARTIAL and set by regulation. Three conditions define its real scope: the benefit is gated by a fiscal quota that the province sets each year through the budget (art. 7); the beneficiary must be domiciled or incorporated in San Juan, or authorized to operate in its territory, or establish itself there for that purpose, and must register with the enforcement authority, with an Exploration and Business Plan that opens up its local purchases and contracting (art. 6); and the enforcement authority is the Ministry of Mining (art. 8). Its sister law, 1722-M, creates the Mining Entrepreneurial Activity framework and the Provincial Fund of Incentives for Mining Entrepreneurs (mixed trust, founding contribution of 500 million pesos); its art. 9 announces a turnover tax and Stamp Tax exemption regime but is NOT self-executing: it directs the Executive to pursue the enactment of the pertinent rules. verif Feb 16, 2018 ↗
Split of mining royalties among province, municipality and mining authority: ley provincial 716-M sets out, in its section 17, TWO different schemes depending on the date of the exploitation Environmental Impact Declaration (DIA). (1) Projects that as of Nov 29, 2007 had an approved Exploitation Environmental Impact report with a DIA —or had filed it and were in the final stage of obtaining it—: 55% to the Province's General Revenue, 33% to the Municipality where the deposit is seated and 12% to the Ministry of Mining. (2) Projects that obtained such approval, or whose Exploitation Environmental Impact reports are later than Nov 29, 2007: 70% to General Revenue, 20% to the Municipality and 10% to the Ministry of Mining. Under either scheme the municipality's funds must go to strategic economic, productive, industrial or tourism development projects that generate employment, and to housing construction; they cannot go to current expenditure. The Ministry of Mining's share is deposited in a special account and split 65% enforcement and ecosystem preservation, 25% mining promotion and 10% Secretariat of Science, Technology and Innovation. verif Aug 8, 2026 ↗
Key indicators
San Juan
Key indicators
San JuanSan Juan is already Argentina's first copper district in development, yet it does not export a single dollar of copper: its entire mining floor today —13.46% of GRP, 87.6% of provincial exports in January-August 2026— is gold and silver (Veladero, Gualcamayo). The bet is the transition. Vicuña (USD 18,100 M), Los Azules, El Pachón and the ~700 MW power expansion turn the province into a decade-long copper construction site, with an overlapping build peak in 2026-2030. Service demand is not generated yet by copper operations —which start around 2030— but by the construction already underway and the high-voltage grid that must be laid first.
What cools it downa delay in Vicuña's FID (which the company places, at the earliest, at the end of 2026) or in sealing the RIGI pipeline —El Pachón is still not approved— pushes the whole construction curve forward, and with it the peak of service demand.
87.6%
of what San Juan exports is mining (January-August 2026)
the full data
In the first 8 months of 2026 mining accounted for 87.6% of the province's total exports. Mining exports came to USD 1,302 M (+10.1% year on year; same period 2025: USD 1,183 M), 21.5% of the entire country's mining exports (2nd-largest mining exporter behind Santa Cruz). Gold was 97.9% of the mining basket for the period and 99.5% in August; the rest is lime and other minerals verif. Copper does not export yet: no copper project is in production prob.

Vicuña's capex (BHP-Lundin), the largest mining project in Argentine history
the full data
Lundin's integrated technical study for Vicuña, published on 16-Feb-2026, projects capex of USD 18,100 M in 3 stages (7,100 + 3,900 + 7,100). It covers Josemaría and Filo del Sol, in the Iglesia department, with average production of ~395,000 t/yr of copper and ~711,000 oz/yr of gold over the first 25 years and first production in 2030 prob. The RIGI Evaluation Committee recommended approving it on 16-Jun-2026 and Resolución 1154/2026 of the Ministerio de Economía approved its accession as a Long-Term Strategic Export Project (Official Gazette of 30-Jul-2026) verif. In February 2026 the company placed the final investment decision, at the earliest, at the end of that year prob.

El Pachón (Glencore), the 2nd mega-copper: filed with the RIGI and not approved as of 2-Oct-2026 — its approval is THE event to watch in the pipeline
the full data
Glencore filed El Pachón (copper and molybdenum, with silver; Calingasta department) with the RIGI on 18-Aug-2025 for a Phase 1 of USD 9,500 M. That is the midpoint of the 8,500-10,500 range stated in the application. Declared resource ~6,000 Mt @ 0.43% Cu. The company expects more than 10,000 direct jobs in construction and more than 2,500 in operation, but for El Pachón and Agua Rica combined (company figure) verif. As of 2-Oct-2026, when the approval of Agua Rica was announced, El Pachón was still not approved: it is the only one of San Juan's major copper projects still awaiting the act prob.
~700 MW
of new electric power the mountains need by 2030 — the grid expansion modelled for the three copper projects at once
the full data
The grid expansion modelled for the three copper projects at once now holds a certificate. ENRE Resolución 219/2026 (Official Gazette 24-Apr-2026) had put to public hearing the expansion of the transmission system for San Juan mining, with ~700 MW of demand modelled to 2030 (Vicuña 260 MW + Los Azules 140 MW + El Pachón 300 MW), a new 500 kV Extra High Voltage line Rodeo–Chaparro of 167 km and 90% access priority for 25 years for Vicuña. ENReGE Resolución 330/2026 (Official Gazette 29-Jul-2026) closed that file: it rejected all eleven objections —among them those of the province's own electricity regulator, La Rioja, three municipalities along the corridor and Barrick—, authorized access for the 260 MW of Josemaría phase 1 on the 220 kV busbars of the future ET Chaparro and issued the Certificate of Public Convenience and Necessity for the five works to Transener, at Vicuña's request verif. It remains the physical bottleneck of the boom: without the grid, the construction peak cannot be supplied; but the risk shifted from an open permit to an execution schedule thesis.
Investment climate
analyst reading
Investment climate
analyst readingSan Juan is not yet the province of copper: it is the province turning into one.
Its floor —what pays the bills today— is gold: Veladero and Gualcamayo account for 87.6% of what the province exports (January-August 2026) and anchor 13.46% of its GRP. On that floor it builds the largest development in Argentine mining: three overlapping copper mega-projects —Vicuña (USD 18,100 M, approved under the RIGI), Los Azules (McEwen, already approved) and El Pachón (Glencore, USD 9,500 M, filed)— plus the ~700 MW grid the mountains need to sustain them. San Juan has four mining projects approved under the RIGI today.
See the full analysis
Confidence rests on verifiable facts: a Vicuña technical study with capex and 25-year production, a comprehensive governor–Vicuña agreement that puts infrastructure and public works on the miner's account, and an ENRE resolution that already models electricity demand to 2030. The opportunity for those who plug in is not generated yet by copper operations —which only start around 2030—: it is generated by construction, which already hires and already buys. And the timing? Frankly: in Q1 2026 the country's aggregate investment (INDEC's gross fixed capital formation) fell 11.6% year on year.
But for San Juan that number reads the right way up: copper capex is a 25-year decision made on the metal price and RIGI stability, not on the quarter. The real risk is not that capital won't come —the studies, the amounts and the four RIGI approvals are already there—: it is timing. The company places Vicuña's FID, at the earliest, at the end of 2026, and El Pachón is still not approved; every month of delay pushes the construction peak forward. Entering now, with the works starting and the local supplier market still to be built, is entering early.
What to watch
Confidence holds by facing head-on what tests it. The factors to follow closely:
- The price of copper (LME) and gold, and Vicuña's FID: the three copper studies assume incentive prices and Vicuña is the most sensitive (IRR ~14.8%); copper below the FID threshold —or gold falling sharply, which would break the 87.6% export floor— would slow satellite construction demand.
- Social license and the implementation of the Glaciers Law: the reform is NOW law (Ley 27.804, passed 08-Apr-2026, enacted by Decreto 271/2026, Official Gazette 24-Apr-2026), and it lifted the indefinite environmental veto that hung over high-altitude copper —a clearance in favor of Vicuña and El Pachón, which operate in a periglacial environment—. The vector to watch is no longer passage but its provincial implementation and judicial risk: there is a real precedent of stoppage (in April 2026 a La Rioja court order banned Vicuña's transit through La Rioja for 30 days, and the company rerouted its logistics through San Juan).

Impact on San Juan: Ley 2827-M only counts RE.PRO.MIN registrants towards its 60% purchasing floor. The national roll helps a San Juan supplier be found from outside the province, not get inside the quota at home. mixed stability → long-term investment thesis
▸Salta: 70/60 local mining procurementSalta Ley 8164 (Official Gazette Oct 22, 2019)in forcePROVINCIAL2019
Impact on San Juan: The San Juan supplier that wants to scale into the neighboring mining belt runs into a definition of «local» that excludes it: Salta requires a Salta domicile, 80% of payroll domiciled in Salta and 51% of capital in Salta hands, or a Salta partner with 30% of the joint venture. San Juan reserves demand for it with its own 80/60 rule, but the same mechanism caps it next door: each province forces the corporate structure to be replicated. adverse federal-provincial tension thesis

Impact on San Juan: It is the entry key to the spending of the three copper mega-miners thesis. For a purchase to count towards the 60% target, the supplier must be registered and hold a valid certificate in the Mining Suppliers Registry (article 9) verif: provincial homologation stops being a competitive edge and becomes a condition of existence before El Pachón, Los Azules and Vicuña thesis. The requirement that weighs most on the San Juan SME is seniority: 24 months of establishment and domicile in the department of influence, or 12 in the rest of the province, and 24 months in the builders' registry for construction firms (articles 12 and 13) verif; whoever was not there does not make it in time for this wave thesis. The target has two exits for the miner, both on technical grounds: removing from the base the purchases with no local offer on reasonable terms of quality, capacity, quantity, timing or market price (article 9), and setting progressive targets below 60% justified category by category (article 10) verif. favorable thesis

The decree writes that renewing or rehabilitating existing track counts as construction for the incentive regime, provided a verifiable capacity increase is certified: the rail option can now build a case with 30-year tax stability, and that enters the comparison. favorable stability → long-term investment thesis
Fiscal and monetary anchor3
▸Fiscal anchor: surplus two years in a rowExecutive execution policy on the extended budget (Decreto 1131/2024)in forceNATIONALFeb 1, 2026
Impact on San Juan: San Juan's three copper giants — Vicuña (USD 18,100 M), El Pachón (USD 9,500 M) and Los Azules — do not yet invoice a single dollar: their capex is discounted entirely against a rate, with no cash flow of their own to cushion it. With Vicuña's FID expected before end-2026 and an IRR of ~14.8%, a sustained surplus — through a lower risk premium — moves the project above or below the approval threshold. favorable lowers country risk thesis
▸No excise duty on insurance, satellite or vehiclesLaw 27.802, arts. 189 and 195 (Titles XXIV and XXV)in forceNATIONALMar 6, 2026
Impact on San Juan: High-altitude mining runs on heavy fleet and a satellite link as its only means of communication. Removing excise duty from both categories bears directly on the cost of operating a project in the cordillera. favorable confirms the course thesis
▸Losses indexed to CPI, citizenship without tax residenceLaw 27.802, arts. 190, 191 and 194 (Title XXIV)in forceNATIONALMar 6, 2026
Impact on San Juan: San Juan's copper projects are the textbook case of the long tax loss: years of construction with no income and a first sale much later. Indexing those losses to CPI improves the project's cash flow in its first producing years. favorable confirms the course thesis

▸Dollar credit is no longer for exporters onlyDNU 736/2026 (Official Gazette, Aug 14, 2026) · BCRA Communication «A» 8467in forceNATIONALAug 14, 2026
Impact on San Juan: The San Juan copper supplier collects in pesos —the local mining development law reserves 60% of purchases for it and requires a provincial domicile— and equips itself in dollars: high-altitude fleet, camp modules, drilling rigs. That mismatch is what caps its scale. Allowing dollar credit for legal entities without export revenue targets exactly that point. The instrument already exists: BCRA Communication «A» 8467 (Aug 18, 2026) enables it with a cap of 15% of each bank's dollar deposits and 25% more capital required. favorable cheaper to respond: investing takes time, held-back supply shows up at once thesis
Trade opening3
▸Argentina and the US sign their first trade and investment agreementBilateral agreement signed Feb 5, 2026 (no number; pending congressional approval)pendingNATIONALFeb 5, 2026
Impact on San Juan: The agreement opens EXIM Bank and DFC financing for critical-minerals investors, and San Juan copper is Argentina's largest portfolio in that category: Vicuña USD 18,100 M, El Pachón USD 9,500 M, Los Azules. In parallel, Argentina's 0% on 221 machinery and transport lines cuts the cost of imported capex during construction, which is the stage San Juan is in today. The agreement is in process: it needs the approval of Congress and does not apply until voted. favorable lowers country risk thesis
▸Certifications: approval from a reference country is accepted, with no repeat processDecreto 892/2025 (Official Gazette, Dec 17, 2025)in forceNATIONALDec 17, 2025
Impact on San Juan: The San Juan supplier that wants into the 60% local purchase quota has to manufacture or integrate here, not resell imports. With re-certification of what is already approved in the EU or US gone, it can assemble panels, structures and equipment using components certified abroad without repeating local tests, and that purchase still counts as local for Vicuña, Los Azules and El Pachón. favorable opening and deregulation thesis

Impact on San Juan: It is the province with the most copper and gold projects under the Law 24,196 regime in the dataset, and where the local supplier already has a provincial purchasing floor to meet. Letting the service provider import its own equipment duty-free lowers the cost of entry for anyone moving from renting to owning a fleet. favorable

▸Public works: the registries that filtered who could compete fallDecreto 105/2025in forceNATIONALFeb 17, 2025
Impact on San Juan: The national builders' registry falls, but in San Juan the filter that still bites is provincial and fiscal: the tax law charges 2% turnover tax to a builder registered with the Provincial Registry of Public Works Contractors or with IERIC, and 2.50% to one that is not. With the copper construction peak running 2026-2030, half a point on the certificate decides a bid. mixed opening and deregulation thesis
▸Trucks: digital RUTA and the end of extra provincial requirementsDecreto 832/2024in forceNATIONALSep 13, 2024
Impact on San Juan: Project cargo for the three copper mines enters through an interjurisdictional corridor: it crosses La Rioja and exits towards Chile. The decree closes the list of documents that may be demanded and bars provinces and municipalities from asking a RUTA-registered carrier for anything extra. It does not reach the judicial route — access to Vicuña was cut once by a La Rioja injunction — but it removes the administrative layer from the corridor. favorable opening and deregulation thesis

▸Winemaking: the National Wine Institute repeals the bulk of its rulesINV Resolución 37/2025 (RESOL-2025-37-APN-INV#MEC)in forceNATIONALNov 7, 2025
Impact on San Juan: Food and beverages, which includes wine, is 7.21% of San Juan's provincial GDP: the third private sector behind mining and retail. The wine regulator's new code removes transit permits and intermediate inspections and controls the finished product, and that lowers the fixed compliance cost, which is the one that weighs most on the small producer. The injunction reinstating the grape intake certificate runs the other way: it gives the grower back its evidence against the winery. mixed opening and deregulation thesis

Impact on San Juan: It appears in two works, and in both as a node rather than a stopover: work 9 links Rodeo with Chaparro and continues to La Rioja Sur, and work 13 starts at Chaparro to cross to Antofagasta de la Sierra and La Puna. This is precisely the infrastructure the province needs so that copper does not depend on dedicated works project by project, and it gives the San Juan transmission plan a federal anchor it did not have before. favorable the bottleneck moves to transport thesis
▸Mining: export duties to 0% for most productsDecreto 563/2025in forceNATIONALAug 6, 2025
Impact on San Juan: From January to August 2026, 87.6 % of what San Juan exported was mining, and nearly all of it was gold verif. Of gold, the decree's Annex only lists the ore (2616.90) and gold powder (7108.11), not the other unwrought forms (7108.12), where doré is usually classified verif. If the doré from Veladero and Gualcamayo is declared under that position, it does not get the zero rate: this has to be confirmed before assuming the cut lifts their netback thesis. For the copper still to come, the 0% enters the investment-decision calculation thesis. Silver, which ships in the same doré, is left out of the Annex and according to the official communication stays at 4.5% prob. favorable better export netback thesis

Impact on San Juan: San Juan has both the country's largest installed solar fleet and the largest new electricity demand still to come: ~700 MW modelled to 2030 (Vicuña 260, El Pachón 300, Los Azules 140). Opening MATER to bilateral contracting lets a San Juan solar generator sell directly to the mine under a term PPA, bypassing the wholesale administrator.

▸Mining: new procedure for VAT refundsJoint Gen. Res. ARCA-Mining Secretariat 5878/2026 (Official Gazette, Jul 23, 2026)in forceNATIONALJul 23, 2026
Impact on San Juan: The article 14 bis refund is the one for exploration-stage VAT, which Decreto 482/2026 accelerates. It eases the projects that are still exploring and expanding resources before producing (Vicuña, Los Azules, El Pachón). This resolution organizes the procedure; it does not set the deadline. favorable opening and deregulation thesis

▸The registry that turns a supplier into a mining beneficiaryResolution 68/2026 of the Mining Secretariat (Official Gazette, 19 Aug 2026), creating the Mining Investment Registryin forceNATIONALAug 19, 2026
Impact on San Juan: The national registry gives the San Juan supplier a route to import equipment duty-free that it does not use today; but the 60% mining-billing floor clashes with the real profile of many SMEs around Gran San Juan, which combine mining with public works and farming. It coexists with the provincial local-purchase floor, which measures the opposite: how much the mining company buys locally, not how much the supplier sells to mining. mixed

Impact on San Juan: Veladero, Vicuña and Los Azules are supplied by mountain national roads with no alternative: a blockade there cannot be driven around, it stops the operation. The protocol puts federal forces in charge of clearing federal roads, and road blockades are precisely the signal the province's own watchlist records for water conflict and social license in Jáchal and Calingasta. favorable stability → long-term investment thesis

Impact on San Juan: The provincial local mining development law requires 80% of payroll to be from San Juan, in a labor market that has never operated a copper mine: the contractor is forced to hire where the experience does not yet exist.

Impact on San Juan: Here the framework is mining rather than oil and gas, and the effect arrives by another route: the San Juan niches that bill as a SERVICE have their labour cost tied to an industry agreement that makes no distinction between a large contractor and a twenty-person workshop.

Our reading — And the symmetrical risk is stated: managing is not funding — if the agreement transfers responsibility without the resources, the effect on the actual state of the road may be the opposite. The text of the agreement is not published, and that is where the question that decides the impact sits: whether it transfers only management or the funds as well.
San Juan begins a new stage in the integrated management of its roads. Together with Diego Santilli, Luis Caputo, Fernando Herrmann, Marcelo Campoy and Fernando Perea, we signed an agreement that will let us manage national routes that are vital for our province: Routes 40, 20, 153, 150 and 149, plus the 40/A014 road junction. We will have new tools to preserve, improve, maintain and build strategic corridors for our production, mining and tourism.

Our reading — The estimated +80% in own-source revenue is the figure that moves the needle most for provincial fiscal capacity, though it is a projection by the Ministry itself, not an observed figure.
VICUÑA RIGI: Excellent meeting alongside the Coordinating Secretary of Energy and Mining, Daniel González, and the Mining Secretary, Luis Lucero, with Vicuña Corp's CEO, Ron Hochstein, and the Country Director for Argentina and Chile, José Morea. The project approved under the RIGI is for the extraction of copper, gold and silver and will generate exports of more than USD 2,600 million a year and 31,700 direct and indirect jobs. Vicuña has an initial investment of more than USD 9,700 million and will be carried out by BHP and Lundin. Vicuña will also contribute, before year-end, USD 250 million for the Government of San Juan to allocate to public infrastructure works. The contribution is non-reimbursable and not subject to conditions, and will be used for previously agreed works. In addition, Vicuña will contribute to San Juan 1.5% of its gross revenue from the sixth year of production, once the mine is operating. This contribution comes on top of the 3% provincial royalty. The company and the Government of San Juan agreed to hold that 3% royalty stable throughout the life of the mine, currently estimated at 70 years. Based on the figures published in its Preliminary Economic Assessment, the 3% royalties and 1.5% contributions come to more than 100 million dollars a year over the first 10 years, rising to 450 million dollars from 2040. The province currently collects an estimated 430,000 million pesos (280 million dollars) in own resources; this new investment will bring San Juan, on average, 80% more own-source revenue, plus 5,000 new jobs.

Our reading — These USD 250 million do not buy mining services: they buy road, water and sanitation works, which is a provincial tender and not a contract with the miner. For a San Juan construction firm or sanitation-services company, the window does not depend on the project's calendar but on the province's, and it opens when each work is put out to tender. It is the most accessible entry point Vicuña has opened so far for a local SME.
A HISTORIC MOMENT FOR SAN JUAN: we signed an agreement with Vicuña for USD 250 million; a one-off contribution, neither repayable nor offsettable. After more than a year and a half of negotiations, this agreement will allow us to carry out works that will boost local employment, strengthen infrastructure and drive the growth of our province.

Our reading — The implementing decree is the document to read: it sets the procedure for enrollment and certification in RE.PRO.MIN, how long the certificate lasts and how progress is reported; the targets, the exclusion from the calculation base and the penalties are already in the law. Vector to watch: publication of the implementing decree in San Juan's Official Gazette (the law number is already known: 2827-M), and the actual launch of RE.PRO.MIN.
The Local Mining Development Law (local content: 80% of hiring and 60% of purchases from San Juan suppliers, plus the mandatory RE.PRO.MIN registry) was PASSED on 2 July 2026 (33-2) and NOW HAS A NUMBER AND A GAZETTE: it is Ley 2827-M, published on 16 July 2026 and in force according to the official digest. What remains pending as of 29 August 2026 is the implementing regulation — the digest's Implementing Decrees corpus returns 0 results for “2827” — and, above all, the registry actually starting: the Ministry of Mining's website makes no mention of RE.PRO.MIN. The minister had stated the full system would be operational before the end of 2026. ⚠️ The precedent matters and it is what sets what to watch: Ley 1208-M, which this law replaces (and repeals in its art. 31), DID get an implementing decree in 2014, and according to the press its registry never worked ⇒ the milestone is not the decree, it is the registry issuing certificates.

Vectors to watch, in order: (a) whether any of the eleven rejected objectors goes to court —Barrick and EPRE San Juan have the most capacity at stake—; (b) the tender for the 167 km EHV line and the ET Chaparro GIS, which is the real point of entry for suppliers; (c) Vicuña’s FID, still a shareholder decision and not mentioned in this resolution.
ENReGE Resolución 330/2026 (signed 28-Jul-2026, published 29-Jul-2026) closes the file on the grid works that will feed San Juan copper. It does three distinct things, and they are worth keeping apart. (1) It REJECTS the objections —art. 1— of eleven filers, among them San Juan’s own Provincial Electricity Authority, La Rioja’s Energy Secretariat, the municipalities of Calingasta, Jáchal and Iglesia, and the miners Barrick Exploraciones Argentinas, Minera Argentina del Sol, Golden Mining, Casposo and Andes Corporación Minera. (2) It AUTHORIZES access to existing transmission capacity for "the 260 MW demand used to supply the mining complex known as Josemaría (phase 1), to be connected at the future Transformer Station (ET) Chaparro on the 220 kV busbars" —art. 2— and ISSUES the Certificate of Public Convenience and Necessity for the expansion filed by Transener S.A. at the request of Vicuña Argentina S.A. —art. 3—: bay 05 of 500 kV at ET Nueva San Juan, the 500 kV yard at ET Rodeo with a 500/132/33 kV 600 MVA transformer bank, disconnection of the Nueva San Juan–Rodeo line from its 132 kV bays, the "new 500 kV EHV line between ET Rodeo and ET Chaparro of approximately ONE HUNDRED AND SIXTY-SEVEN KILOMETRES (167 km)" and the new ET Chaparro with GIS technology, 500/220 kV - 450 MVA, with "TWO (2) 220 kV line outputs to ET Josemaría". (3) It RATIFIES —arts. 4, 5, 6 and 8— the 90% priority of use over third parties already granted by ENRE Resolución 79/2026: on the Nueva San Juan–Rodeo line at 500 kV that 90% of remaining capacity equals, per CAMMESA’s calculations, 71% of total capacity, and the priority runs for 25 years "from the commercial commissioning of each of the works". Not everything was granted: art. 7 DENIES priority over the 500 kV yard at ET Rodeo, because that transformer’s loading "does not depend appreciably on the project’s demand".

Competitive federalism: with no discretionary federal purse and no tax possible on RIGI projects, governors compete for business location — provincial risk turns around and works in your favor4/4 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 (Ley 5857) and 6 RIGI mining projects landed across 5 provinces that competed to host them.
Open the thesis and its evidence — the reasoning, the pieces, the laws and what we watch
For the investor, provincial adhesion legislation (RIGI/RIMI + single-window + stacked exemptions) becomes a leading indicator of where the next capital lands.

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 (Ley 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 Ley 8451 in August 2024 while keeping its own Ley 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 in the first quarter of 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 (non-automatic transfers in June, the lowest for that month since 2005) and RIGI's art. 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 (non-automatic transfers to provinces fell 87.7% in real terms in June, the lowest June 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 the federal-funding substitution thesis, 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 (Ley 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 our 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 this reading takes for granted these are not sourced facts: this is the part of the reasoning you can argue with
- That the governor decides at the margin: with no federal cash to ask for and no new rent to tax, he would rather compete for investment than raise the pressure on what he already has inside. This is an assumption about political behaviour, not a datum.
- That the shutdown of discretionary federal cash holds. It is the arithmetic counterpart of the surplus: if the surplus gives way, the transfer comes back and the incentive to compete undoes itself.
- That art. 165 of the RIGI holds against whatever a province tries. Today it has one precedent —Río Negro's attempt to tax exports, struck down in 2025— not a body of case law.
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».
When the works are bigger than the place, what sells is service to the works, and it is sold from the provincial capital2/3 solid pieces · under waythesis each phase buys something different + high wages → local non-tradable boom
For a company that wants to sell: in the Andes and the Puna, the contract within its reach is not the works but service to the works (camp, food, staff transport, road maintenance, training), and it is won from the provincial capital.
Open the thesis and its evidence — the reasoning, the pieces, the laws and what we watch
For people who live in the department: the way in is the trade the works cannot find locally, not local retail, which does not receive the wage spending while people live in camp. In large cities it is the other way round: the local SME competes for the works themselves.
The strongest case: 2.1 times the registered jobs of Iglesia estim2.0 times the registered jobs of Los Andes (Salta), with 4,200 workers at the construction peak [validated]The intermediate case: the works are 38% of Andalgalá's jobs but 2.5 times its miners and construction workersThe market where the thesis turns into a sale in San JuanHigh-altitude catering: the spending the thesis says is contracted from the capitalStaff transport: a direct consequence of people not living in the departmentThe same market in the Salta Puna, where Rincón, Sal de Oro, Pozuelos and Diablillos share a departmentThe same market in Catamarca (Andalgalá, Tinogasta, Antofagasta de la Sierra)
Vicuña (Josemaría + Filo del Sol) — copper, gold and silver approvedThe strongest case: 2.1 times the registered jobs of Iglesia estim. The awarded stage of the new camp, about 25%, is being carried out by a consortium in which PowerChina holds the contract, Beijing Chengdong makes the modules in China and RAFA, from Santa Fe, does the civil works prob. The other known contractors are from San Juan city prob: none declared with an address in Iglesia.
Rincón Project — lithium carbonate (Rio Tinto) approved2.0 times the registered jobs of Los Andes (Salta), with 4,200 workers at the construction peak [validated].
Sal de Oro II — lithium carbonate (POSCO) approvedreinforcementThe same department as Rincón. Its known contractors are from Rosario and from the province of Salta prob, and 54 % of its 3,600 construction workers came from the province of Salta, not from the department.
Agua Rica / MARA — copper, gold, silver and molybdenum (Glencore) submittedThe intermediate case: the works are 38% of Andalgalá's jobs but 2.5 times its miners and construction workers. It shows where the thesis starts to hold.
Mining camps and modular housing (San Juan) The market where the thesis turns into a sale in San Juan.
Catering and remote high-altitude site hospitality (San Juan) High-altitude catering: the spending the thesis says is contracted from the capital.
Mining personnel transport and people-to-mine logistics (San Juan) Staff transport: a direct consequence of people not living in the department.
Camps, catering and the community joint venture of the Salta puna The same market in the Salta Puna, where Rincón, Sal de Oro, Pozuelos and Diablillos share a department.
Camps, catering and high-altitude living services in the Catamarca puna The same market in Catamarca (Andalgalá, Tinogasta, Antofagasta de la Sierra).
Trigger: Three mining projects need more people on site than all the registered jobs of the department where they are built: Vicuña, with an average of 5,500 direct jobs, against 2,597 jobs held by residents of Iglesia (2.1 times, and 9.8 times its 560 miners and construction workers); Rincón, with 4,200 workers at peak, against 2,071 jobs in Los Andes (2.0 times); and Sal de Oro, with 3,600, in the same department. Iglesia had 4 lodging businesses with employees in 2022 and Los Andes had 2. In Bahía Blanca, San Nicolás or San Lorenzo, the works of Fértil Pampa, Sidersa or Timbúes are between 1% and 5% of local employment.
Mechanism: R13 × R8. A project's first phase buys the camp, roads, heavy logistics and transport of people (R13 · each phase buys something different). When the place lacks the people and the firms for that, the works bring their workforce from outside and house it in a camp: the high wage that R8 turns into local spending is spent where the worker lives, which is the provincial capital or another province, not the department of the works. The private response (R9 · without controls, supply responds to the boom) does appear, but it comes from firms with the scale to set up and run a high-altitude camp, and those are in the capital. each phase buys something different + high wages → local non-tradable boom
What this reading takes for granted these are not sourced facts: this is the part of the reasoning you can argue with
- That the registered jobs of department residents in November 2023 describe today's local labour supply well. The official series was not updated after that, so it is the starting-point snapshot.
- That the construction employment figure each company publishes is close to the real peak. In Vicuña it is an average over the 40 months of construction its technical study foresees, so the peak is higher.
What we watch (observable data + external vector):
- That the supplier roll of Vicuña, Rincón or Sal de Oro shows that most camp, food or transport contracts are held by firms registered in the department of the works. Vector: each project's local-purchasing reports and provincial registers of mining suppliers.
- That, if the State publishes the jobs-by-department series again, the construction jobs of people living in Iglesia or Los Andes grow by a magnitude comparable to the works (thousands, not tens). Vector: CEP-XXI jobs-by-department series.
Predictions we commit to
- pending From now to 31-Dec-2027, among the camp, food and staff-transport contracts of Vicuña, Rincón and Sal de Oro that become public, most are won by firms registered in the provincial capital or outside the province, not in Iglesia or Los Andes. how we check: The awards and contractors published for Vicuña (San Juan), Rincón and Sal de Oro (Salta), with each firm's registered address. Only those with a declared address are counted.
