The National Mining Company of Chile (ENAMI), along with its international mining partners, updated lithium resource figures, reporting a 28% increase. Current assessments indicate that approximately 14.05 million tonnes of lithium resources are located mainly in the Antofagasta region. New brine surveys have led to a revision that aims to support the global expansion of the electric vehicle (EV) market and will define Chile’s battery-metal supply chain position by April 2025.

Resource Expansion by 3.05 Million Tonnes

Two major lithium-bearing salt flats in northern Chile are pivotal elements in this significant resource expansion. According to ENAMI, La Isla lithium resources now total 2.13 million tonnes which is 150% more than earlier estimates. The updated figure of Aguilar now stands at approximately 1 million tonnes which represents a 40% increase. The combined resource additions from mining projects now total an increased capacity of 3.05 million tonnes, according to Reuters.

Analysts point out that resources represent different categories than reserves despite positive outcomes. Reserves represent quantities that are both economically feasible and ready for extraction but resources include wider geological deposits which may need additional investment and processing innovation together with regulatory considerations (Reuters). Chile maintains its status as the top lithium reserve holder in the world which allows it to remain an essential supplier without competition.

Salares Altoandinos Project Developments

The Salares Altoandinos project by ENAMI demonstrates their intention to benefit from the increased resource inventory. The project achieves optimal positioning across several salar deposits within the Antofagasta area to enhance access to essential brine concentrations. Mid-2025 is the expected completion date for partner selection which will draw attention from mining companies that focus on cutting-edge brine extraction methods. ENAMI's recent statements indicate a shift toward joint ventures rather than independent projects to spread technical and financial risks.

Through this programme Chile demonstrates its dedication to utilise its lithium resources amid escalating worldwide battery market needs. Technologically advanced mining partners can help enhance brine extraction efficiency while adhering to local environmental standards.

Impact on the Global Battery-Metals Market

The 28% resource boost reinforces Chile's critical role in the battery metals supply network. The new figures released by analysts suggest that lithium shortages expected from the boom in global EV production might be alleviated while lithium-ion batteries continue to be the primary energy storage solution.

The global markets could experience price volatility shortly. A larger supply pool typically leads to reduced prices but intense demands from EV and grid storage markets can maintain stable market directions. Supply chain operators and traders will closely monitor announcements of the regulatory framework and production timelines, as these factors can affect future pricing.

Opportunities for UK-Based Investors

UK investors find strategic investment opportunities in Chile's updated lithium reserves, which span multiple asset classes. The announcement of specific international mining partners could trigger renewed investor interest in lithium equities associated with ENAMI partnerships. The Salares Altoandinos project development will drive increased demand for mining-service providers who focus on extraction efficiency and sustainability enhancements.

Investors can benefit from Chile’s expanded resource base via Exchange-Traded Funds (ETFs) that target the battery-metals supply chain without needing to purchase individual stocks. Analysing the weighting of lithium stocks within these ETFs could provide valuable insights for portfolio allocation decisions.

Key Takeaways for UK Portfolios

Institutional investors who track commodity markets will find Chile’s updated lithium reserves and ENAMI’s project path to be critical developments. Analysts advise investors to track partnership announcements, regulatory updates and financing rounds for the Salares Altoandinos project to maximise portfolio exposure.

The significant role lithium plays in battery metal supply chains enables Chile’s unexpectedly large reserves to match evolving EV market trends, establishing its leadership position in the sector.
