The Ministry of Economy approved the incorporation of Rincón Mining PTY LTD. Argentina Branch to the Large Investment Incentive Regime (RIGI), as a Long-Term Strategic Export Project, within the Mining sector, subsector Potassium and Lithium.
The measure was made official through the Resolution No. 735/2025, published today (June 03.06.2025, XNUMX) in the Official Gazette. This is the first mining project to access this regime, designed to encourage long-term investments in sectors considered strategic for the country's development.
Investment details and stages
The company is committed to invest a total of USD 2.744 billion until 2029 to develop a “battery-grade lithium carbonate” production plant, with an initial capacity of 53.000 tons per year and a projected capacity to reach 60.000 tons per year.
The investment will be divided into two steps Main:
- Stage 1 (2024–2027): USD 1.653 billion
- Stage 2 (2026–2029): An additional USD 646 million
The investment in "qualifying assets" amounts to USD 2.299 billion, exceeding the minimum threshold required by the RIGI.
The “Rincón Project” is located in the Rincón Salt Flat, department of Los Andes, province of Salta, covering an area of 84.687 hectares.
Nanofiltration and brine pretreatment processes will be used to prevent solar evaporation, aligning with environmental sustainability practices.
In addition, the plant will use "direct extraction (DLE)" technology, which does not require evaporation ponds, making the process more efficient and environmentally friendly.
Tax, customs and exchange benefits
By joining the regime, Rincón Mining will be able to access the “tax, customs and exchange incentives” provided, and will receive a “Special CUIT" granted by the Customs Collection and Control Agency (ARCA), which simplifies administrative procedures.
It is also authorized to “import of capital goods"according to the approved list.
The project was recommended by the RIGI Project Evaluation Committee, which highlighted its export potential, technological impact, and contribution to national productive development.
The Ministry of Mining confirmed compliance with the “technical and environmental requirements” and the Central Bank supported the “exchange rate incentives" planned.
Formal incorporation into the regime will take place on May 19, 2025. In the first two years, the company must demonstrate compliance with at least "20% of the minimum investment amount."
Implications for mining and sustainable development
This approval marks a turning point for Argentine mining policy, consolidating the country as a competitive player in the international lithium market, a key sector for batteries and electric mobility.
In addition, it establishes a precedent for sustainable mining, integrating “technological innovation,” “environmental responsibility,” and “local employment generation,” in line with the objectives of economic growth and accumulation of international reserves.
Aduana News is the first Argentine customs newspaper to launch its digital version. With 20 years of experience, its publications and initiatives aim to provide the most relevant knowledge on customs issues in order to contribute to safe trade in the region.
