Argentina moves to classify rare earths as strategic state assets

The mining commission of Argentina's Chamber of Deputies has approved a motion to classify rare earth elements as first-category minerals under Article 3 of the Mining Code. This legislative step aims to formally recognize these materials as of strategic national interest, thereby establishing a clearer regulatory framework for their geological development and exploitation within the country.

The proposal responds to the absence of explicit references to rare earths in the current Mining Code, which has created ambiguity regarding their classification. By placing elements such as terbium, dysprosium, scandium, and yttrium in the first category, the state would assert exclusive ownership, requiring concessions for exploitation. This move aligns rare earths with other state-controlled metalliferous resources like lithium and copper, distinguishing them from second-category non-metallic substances.

Legislative consensus on strategic status

Deputies reached agreement on the necessity of specific regulations to facilitate the economic utilization of these critical minerals. The elements are essential for industries including electric vehicles, clean energy, defense, and advanced electronics. However, the commission did not reach a consensus on whether to include rare earth projects in the Large Investment Incentive Regime (RIGI), a framework designed to attract foreign capital for exploration, production, and refining.

While the inclusion in RIGI would serve as a direct signal to investors, the primary objective remains the reclassification of these minerals to accelerate project timelines. The recent scope of the commission establishes a basis for continued dialogue, with the current focus on legal certainty rather than immediate nationalization, though the concept of deepening state control has not been ruled out.

Geological resources and exploration potential

According to the Argentine Geological Mining Service (Segemar), the country holds approximately 190,395 tonnes of identified rare earth resources, with a potential 3.3 million tonnes yet to be explored. Primary mineralization is concentrated in the provinces of Salta, Jujuy, San Luis, and Santiago del Estero. Additional deposits exist in the pegmatites of the Valle Fértil district in San Juan and in clay deposits across Córdoba and the Barker area of Buenos Aires.

Offshore exploration also presents significant appeal, with studies indicating the potential for ferromanganese crusts containing rare earth elements on Argentina's continental shelf. This dual onshore and offshore potential positions the country as a key supplier of critical minerals, provided it can enhance applied research and adopt digital solutions to improve efficiency and sustainability standards.

Corporate activity and market implications

Among active projects, Litica Resources, a subsidiary of Pluspetrol, operates the most advanced exploration initiative. The company is developing a 320,000-hectare site in the Río Grande salt flat in Salta, where it maintains a research center to test efficient extraction methods. This operational activity underscores the commercial viability of the sector, even as legislative frameworks evolve.

As noted by World Bank Group officials in an interview with GN auto stocks/materials: rare earths, Argentina's ability to drive new skills and raise safety standards will be critical. A robust legislative framework is viewed as a necessary step to unlock these resources, ensuring that the country can effectively participate in the global supply chain for critical minerals.
