Pozuelos-Pastos Grandes (PPG)
The largest RIGI application filed by Salta and the one its portfolio was missing: >USD 3,000 M across three phases over the Pozuelos and Pastos Grandes salt flats, filed on 28-Feb-2026 and still unresolved, with approval expected by the company by the end of 2026. Build-out capacity across the three phases is 150,000 tonnes a year of lithium carbonate equivalent (LCE), stated as such by Lithium Argentina on 24-Aug-2026 - previously the two press sources gave it as «tonnes of lithium» without specifying the unit, and the gap between the two readings is about 5.3x. The project brings three neighboring deposits under a single basin-wide development: Ganfeng's Pozuelos-Pastos Grandes and Lithium Argentina's Pastos Grandes and Sal de la Puna. The joint venture was signed on 24-Aug-2026 with 67% Ganfeng and 33% Lithium Argentina, Ganfeng operates from Salta, and completion is expected in September 2026. The two companies have invested USD 1,800 M to date between property acquisition and development, and are still looking for a minority investor to finance construction.

Who owns it
Ganfeng Lithium 67% and Lithium Argentina AG 33%, under the Dutch holding company Millennial Lithium B.V.; Ganfeng's team in Salta is the operator. Ganfeng holds its stake through Ganfeng Lithium LATAM and its subsidiary Lithea Inc.

The works, milestone by milestone
Ganfeng and Lithium Argentina sign the definitive joint venture agreements: 67% and 33%, consolidated under the Dutch Millennial Lithium B.V., with Ganfeng's team in Salta as operator and closing expected in September 2026, according to Lithium Argentina's own release.
The RIGI accession application is filed for more than USD 3,000 M across three stages. Lithium Argentina itself later confirmed it: « Application submitted in Q1 2026, incorporating the full 150,000 tpa of LCE development plan, with approval expected by the end of 2026 ».
The province reports that the project already holds the environmental impact declaration for its first stage and announces Ganfeng's commitment with CAPEMISA on Salta suppliers. The declared development runs in three stages, with an initially approved capacity of 50,000 t/yr scalable to 150,000 t/yr, a 25-year life and a 3-year ramp-up.
Who already has a contract
The project has been filed under the RIGI and has not been approved yet. Construction awards come later.
How to supply itwhere to register, what they ask for and what they will buy
How to become a supplier
It cannot be stated yet. The project has applied to the RIGI and has no resolution, so no single-project vehicle has been determined; the first stage's environmental impact declaration was issued to Lithea Inc., Ganfeng's Argentine subsidiary, and the Argentine holding companies will sit under the Dutch Millennial Lithium B.V. Invoicing the wrong legal entity is a real risk while the structure remains open.
Ganfeng's team in Salta operates the project, as Lithium Argentina itself stated on 24-Aug-2026. ⛔ But there is no construction procurement process open today, and that is worth saying plainly: the joint venture was closing in September 2026, the financing is still being assembled with a minority investor yet to be found, and the company itself expects the RIGI resolution only by the end of 2026. No project of this scale breaks ground with all three still pending.
The registration routes that exist today, with their status. The one that is up and running is not always the official one.
RPPLEM — Salta Provincial Registry of Local Suppliers to Mining Companies
up and running todayThis is the registry created by art. 15 of Ley 8164 and the only one the law recognises. It is up and running and its roll is public: as of 31-Jul-2026 it listed 500 suppliers with approved applications, showing tax ID, legal name, registration date, chamber membership and line of business.

announced onlyGanfeng and CAPEMISA announced a commitment to work together so that Salta suppliers get new opportunities. Verbatim from the governor: « esa misma politica de Estado suma un nuevo capitulo con el reciente compromiso de Ganfeng y CAPEMISA de trabajar juntos para que los proveedores salteños tengan nuevas oportunidades ». ⚠️ It is an announcement, not a working channel: there is no published agreement, no percentages, and no verified matchmaking round with this operator.
Go to the single windowabrirWhat they ask you for
Qualify as a local supplier under art. 16 of Ley 8164, which requires four things at once: registered or corporate AND tax domicile in Salta; at least 80% of the payroll living in the province; for a company, 51% or more of the capital held by partners domiciled in Salta; and for a joint venture, a Salta partner with a minimum 30% stake. verif Oct 22, 2019 ↗Verbatim from art. 16: a local supplier must « constituir y mantener domicilio real o social y fiscal en la Provincia de Salta »; have « al menos el 80% de su nomina de trabajadores » living in Salta; if a legal entity, be registered in Salta with « el 51% o mas de su composicion societaria » held by partners domiciled in the province; and if a joint venture, a Salta partner with a minimum 30% stake.
Be registered in the Provincial Registry of Local Suppliers to Mining Companies (RPPLEM) and keep the certificate current: it expires two years after issue. verif Jul 31, 2026 ↗The registry is created by « la Ley N° 8164, en su artículo 15 », is free and public, is run by the Secretaría de Minería y Energía (Av. Bolivia 4650 PB, Salta), and the certificate runs for « dos años contados desde que se emitió ».
The specialised professionals and technicians the supplier puts on the job must be licensed by the province's own professional association. verif Oct 22, 2019 ↗A requirement of art. 16 of Ley 8164, read in the text published in the provincial official gazette: specialised professionals and technicians must be licensed by the corresponding provincial association.
Be on the roll on inspection day, not on an annual filing: enforcement cross-checks the list of suppliers present AT THE MINE against the Registry, on the spot. prob Aug 28, 2025 ↗Verbatim from the official release of 28-Aug-2025: « las empresas mineras deben brindar en mina, al momento de la inspeccion, la nomina de todos los proveedores », cross-checked « con el Registro de Proveedores Mineros ». The same measure gives CAPEMISA the power to « formular observaciones en el procedimiento » of registration.
Get the local-content file ready for stages 2 and 3: art. 20 of Ley 8164 makes approval of the environmental and social impact study of a first-category project conditional on a progressive local-hiring system of between 40% and 70% of total payroll, depending on the stage and the size. PPG has only its first stage approved. verif Oct 22, 2019 ↗Art. 20 of Ley 8164: to approve the Environmental and Social Impact Study of a first-category project, the authority requires a progressive local-hiring system set between 40% and 70%, measured on payroll.
The order you get in by
Register with the RPPLEM at the Secretaría de Minería y Energía. It is free and public, and without a current certificate the purchase does not count towards the miner's local-content target. the certificate expires two years after issue
If the ownership structure falls short of 51% Salta-held, form a joint venture with a local partner: art. 16 accepts a joint venture with a Salta partner holding at least 30%.
Join CAPEMISA or ask to be included in its matchmaking rounds: it is the chamber the provincial government placed inside the process, and the one that convenes the meetings with the operators.
What it will buy, and when
It is the largest RIGI application filed by Salta, more than USD 3,000 M across three stages, and it has been unresolved since Feb 28, 2026: a commitment on that scale rests on being able to repatriate the return, which is what the regime promises and free access to foreign exchange delivers.
Three stages across the Pozuelos and Pastos Grandes salars, in the Salta puna: if it is approved, the first market to open is not the plant's but that of keeping people at altitude —camp, food, transport, health care—, in towns that do not offer that today.
We have not built this project’s phase → demand chain: its schedule still has to be crossed with the province’s catalog of markets and trades.
What it will need and has no supplier for yet
Hydrogeology, flow model and sign-off of the consolidated basin's resource report
mediumPPG 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 meter 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.
Local-content file for the environmental permit of stages 2 and 3
mediumThis is what a foreign supplier chain cannot self-supply: it requires an Argentine license and a file before the provincial authority. The clock is a rule in force and read in its primary source: article 20 of Ley 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.

The RIGI act, in detail
The project has been filed under the RIGI and has not been approved yet. The instrument is published in the Boletín Oficial once the Committee approves the accession.
What we could not confirm
There are 2 in this project. Each says why it could not be confirmed and what it would take to close it.
H-01When construction starts and when operation begins+
The schedule of a RIGI project is read in the recitals of its admission resolution, and this project has no resolution published in the Official Gazette yet: it has been filed or announced, not approved. What circulates in the press are tentative company dates, with no act fixing them.
H-02Who holds a contract on the project, and the permanent infrastructure it would leave behind+
This is a pre-construction project with three open blockers — the joint venture not yet closed, the financing still being assembled and the RIGI application unresolved — so there are no awards to look for: no source names a PPG contractor, and the contracts Ganfeng holds at Mariana, a different project of the same operator in the same province, are not counted as this project's. Likewise, no permanent infrastructure has been published with a magnitude.
