Pro-mining cooperation / own agendaour own interpretation, anchored in the verified facts ↓
Pro-mining cooperation with the national investment agenda: San Juan joined the RIGI (Law 2671-I, 15-Aug-2024) and is the country's leading province in mining RIGI projects (4 approved: Los Azules, Gualcamayo, Veladero Phases 8-9 and Vicuña as the first copper PEELP). In parallel it runs an intense agenda of its own: the Local Mining Development Law (80% local employment / 60% local purchases, passed 02-Jul-2026) and direct negotiation of an integrated agreement with Vicuña Corp (infrastructure + public works funded by the miner + royalty stability, Vancouver Mar-2026).

San Juan levies no new taxes on the mine: it charges a 3% FOB royalty (national Law 24,196, with 30-year fiscal stability) and negotiates per-project agreements —the integrated agreement with Vicuña adds infrastructure and public works funded by the miner plus royalty stability—. What the province does impose is local content: 80% of jobs and 60% of purchases sourced in San Juan (Local Mining Development Law, passed Jul-2026; regulations and the RE.PRO.MIN registry promised before the end of 2026).
Fiscal regime & incentives in detail
Mining royalties: 3% of exported FOB value (under national Law 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%. Cumulative 2005-2025: USD 594.1 M. The integrated agreement negotiated with Vicuña Corp (Mar-2026) also contemplates a per-project royalty-stability framework. prob · May 2025 ↗

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, 91% of provincial exports— 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 (expected before the end of 2026) or in sealing the RIGI pipeline —Vicuña's resolution still not out in the Gazette, El Pachón not yet approved— pushes the whole construction curve forward, and with it the peak of service demand.
91%
of what San Juan exports is mining
the full data
In the first 4 months of 2026 mining accounted for 91.0% of the province's total exports: USD 849 M in mining exports (+39.9% year-on-year; same period 2025: USD 607 M), 26.1% of the entire country's mining exports (2nd-largest mining exporter behind Santa Cruz). Gold was 99.0% of April 2026's mining basket — all current flow is gold/silver; copper does not yet export a single dollar.
USD 18,100 M
Vicuña's capex (BHP-Lundin), the largest mining project in Argentine history and the RIGI's first copper PEELP
the full data
Lundin's Integrated Technical Study (ITS) for Vicuña (Josemaría + Filo del Sol, Iglesia department) projects capex of USD 18,100 M across 3 stages (7,100 + 3,900 + 7,100), average production of ~395,000 t/yr of copper and ~711,000 oz/yr of gold over 25+ years, and first production in 2030. The RIGI Committee approved it as the country's first copper PEELP (Jun-2026); the Ministry of Economy's resolution is still pending publication in the Official Gazette and the final investment decision (FID) is expected before the end of 2026.
USD 9,500 M
El Pachón (Glencore), the 2nd mega-copper: filed with the RIGI and under review — its approval is THE event to watch in the pipeline
the full data
Glencore filed El Pachón (copper, silver and molybdenum; Calingasta department) with the RIGI on 18-Aug-2025 for a Phase 1 of USD 9,500 M (midpoint of the 8,500-10,500 range stated in the application). As of 19-Jul-2026 it remains under review, NOT approved: it is the only one of San Juan's major copper projects still awaiting the act. Declared resource ~6,000 Mt @ 0.43% Cu; expected employment +10,000 in construction and +2,500 in operation (company figure).
~700 MW
of new electric power the mountains need by 2030 — the grid works that enable all three copper projects at once
the full data
ENRE Resolution 219/2026 (Official Gazette 24-Apr-2026) called a public hearing on expanding the transmission system for San Juan mining: ~700 MW of demand modeled 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, with 90% access priority for 25 years assigned to Vicuña. It is the boom's physical bottleneck: without the grid, the construction peak cannot be supplied.
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 91% of what the province exports and anchor 13.46% of its GRP. On that floor it stakes the largest bet in Argentine mining: three overlapping copper mega-projects —Vicuña (USD 18,100 M, the RIGI's first copper PEELP), 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 is, today, the country's leading province in mining RIGI projects. Confidence rests on verifiable facts: a Vicuña technical study with capex and 25-year production, an integrated governor–Vicuña agreement that puts infrastructure and public works on the miner's account, and an ENRE resolution already modeling 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?
In all honesty: 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 RIGI leadership are already there—: it is timing. Vicuña's FID is expected before the end of 2026, Vicuña's RIGI resolution is still unpublished in the Gazette and El Pachón is still unapproved; 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. Two 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 91% export floor— would cool satellite construction demand.
- Social license and the implementation of the Glaciers Law: the reform is NOW law (Law 27,804, passed 08-Apr-2026, enacted by Decree 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 (a La Rioja injunction went as far as halting access to Vicuña before being overturned by the San Juan courts).

Ecosystem companies · San Juan
These six companies are the demand side of the market a supplier plugs into: the operators you invoice. Minera Andina del Sol (Veladero, Barrick-Shandong JV) and Minas Argentinas (Gualcamayo) bill the gold that sustains the province today; Vicuña Corp (BHP-Lundin), McEwen Copper (Los Azules) and Glencore (El Pachón) put up the capital for the copper to come. Vicuña is also already the largest buyer in San Juan's supply base: 264 supplier companies, 158 from San Juan (~60% of contracts) — already brushing the 60% the local-content law requires. The opportunity map above comes from crossing demand with local supply: where copper construction grows and the San Juan supplier does not yet reach.
The crackThe entry gap here is not only capital: it is a law. The Local Mining Development Law reserves 60% of purchases and 80% of jobs for San Juan residents and creates RE.PRO.MIN, the mandatory registry of mining suppliers. Whoever settles and gets certified first enters a market reserved by rule —with the caveat that the local supplier offers competitive terms— rather than fighting for share against a twenty-year incumbent in gold.

Who it affects
Miners (copper/gold/silver) operating in San Juan and supplier SMEs. Supplier requirement: an operating establishment + legal and tax domicile in San Juan and >=51% of the share capital in local residents, OR evidencing 24 months of billing with an establishment in the province. Priority order: 1) directly influenced communities (e.g. Jáchal, Iglesia, Calingasta), 2) indirect influence, 3) rest of the province, 4) national, 5) foreign. Local worker: 12 months of accredited residence. Sanctions: up to 60,000 tax units, suspension or cancellation of registration. Incentive: a tax-credit certificate applicable to provincial taxes for whoever simultaneously meets 80% employment + 60% purchases.
Our reading: It is now law: San Juan replicates the Salta moat over 28.5% of the national RIGI portfolio by amount estim, and provincial homologation becomes the entry key to the quota of the copper mega-miners (El Pachón, Los Azules, Vicuña) [enactment verified; the final wording, probable]. It is San Juan's piece of the local-procurement thesis — the same reading as Salta: governor's policy, not the national program's. The nuance that decides how much the moat weighs: the 60% procurement target applies only where the local supplier offers competitive terms prob — a quota with an escape valve, not a blank cheque for the San Juan supplier. thesis

PENDINGregulation of the Local Mining Development Law + launch of RE.PRO.MIN (before the end of 2026)2026-07-15 ↗
The Local Mining Development Law (local content: 80% of jobs and 60% of purchases from San Juan suppliers, plus the mandatory RE.PRO.MIN registry) was PASSED on 02-Jul-2026 (33-2), but its regulations, its law number and its publication in San Juan's Official Gazette are still pending. The Minister of Mining stated that the full system —including RE.PRO.MIN, 'well advanced'— will be operational before the end of 2026. The law replaces Law 1208-M, an earlier local-content rule that was never effectively applied.
Our reading — [INFERENCE] For the local supplier, RE.PRO.MIN is THE registry to enroll in first: provincial accreditation becomes a condition of entry to the quota of the copper mega-miners (Vicuña, Los Azules, El Pachón). The implementing decree is the document to read —it sets thresholds, deadlines, the competitiveness valve and enforcement—. Vector to watch: publication of the law number and the implementing decree in San Juan's Official Gazette, and the actual launch of RE.PRO.MIN. federal-provincial tension unconf
PENDINGformalization of the integrated San Juan Government–Vicuña agreement (infrastructure funded by the miner + royalty stability)2026-03-09 ↗
Governor Orrego consolidated in Vancouver (Mar-2026) the terms of an integrated agreement with Vicuña Corp (BHP-Lundin JV): infrastructure and public works funded by the miner, plus a per-project royalty-stability framework. It is the 'per-project agreement' model that San Juan negotiates alongside the national RIGI. The definitive legal instrument that would set those commitments —and their exact scope— has not yet been published.
Our reading — [INFERENCE] The instrument that formalizes the agreement will define which infrastructure works are included (roads, energy, water), who tenders them and with what local-content requirement — it is the document to read when it comes out. Vector to watch: the provincial law or decree that ratifies the integrated agreement and its detail of works, investments and royalty stability. federal-provincial tension + lowers country risk unconf
Convergence thesis · San Juan
1 thesis · how the pieces convergeWhen several pieces of the dataset —reforms, RIGI, opportunities— push in the same direction, we read them as a single actionable story. It is our reading (thesis seal), not a data point. The traffic light is not our opinion: it is derived from the real status of each piece — if the rules are in force, the thesis is ready to execute.
Competitive federalism: with no discretionary federal purse and no tax possible on RIGI projects, governors compete for business location — provincial risk flips into a tailwind3/3 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.
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».
