White Gold Rush

Critical Minerals of the Americas and the New Resource Geography

The White Gold Rush

Beneath the salt flats of the Andes, the desert basins of Nevada, and the boreal shield of northern Quebec lies the raw material of the twenty-first century’s defining industrial transformation. Lithium powers the batteries in every electric vehicle, grid-scale storage system, and portable device on the planet. Rare earth elements make the permanent magnets in EV motors and wind turbines possible. Cobalt, nickel, and copper wire the entire energy transition together.

The geography of these minerals is reshaping geopolitics. China dominates rare earth processing at roughly 60 percent of global output, and has invested heavily in South American lithium through companies like Ganfeng Lithium. The United States, despite sitting on vast deposits, produces almost no lithium domestically. The sole operating mine at Silver Peak, Nevada, has run since 1966 but supplies a fraction of national demand. The Inflation Reduction Act (2022) tied EV tax credits to domestic critical mineral sourcing, triggering a rush to permit new mines from the Nevada desert to the Minnesota wilderness.

The Lithium Triangle sits at the high-altitude salars of Chile, Argentina, and Bolivia, and holds roughly 60 percent of the world’s known lithium reserves. But extraction comes at a cost. Brine pumping depletes aquifers in some of the driest places on Earth, and Indigenous communities from the Atacama to the Boundary Waters have challenged projects that threaten their land and water. Every mine on this map sits at the intersection of industrial demand, environmental consequence, and political choice.

The Lithium Triangle

The Lithium Triangle straddles the high Andes where Chile, Argentina, and Bolivia meet. Salt flats called salares, at 2,300 to 4,000 meters elevation, formed over millions of years of volcanic activity that concentrated lithium in underground brines. Extraction is deceptively simple: pump brine into evaporation ponds, wait 12 to 18 months for the sun to do its work, then harvest lithium carbonate from the residue. The process is cheap but water-intensive. The Atacama Desert, where Chile’s Salar de Atacama sits, is the driest non-polar place on Earth.

Chile produces roughly a quarter of the world’s lithium through two operators at the Salar de Atacama: SQM (state-partnered) and Albemarle (US-based). Argentina has taken a more open approach, welcoming foreign investment into provinces like Jujuy, Salta, and Catamarca. Chinese firm Ganfeng Lithium is a major partner at the Cauchari-Olaroz project. Bolivia sits on the largest reserves of all at the Salar de Uyuni (21 million tonnes), but state control through YLB and technical challenges with high-magnesium brines have kept production minimal.

The triangle’s dominance is now being challenged by hard-rock deposits in Australia, Canada, and Brazil, where lithium is mined from spodumene pegmatites rather than evaporated from brines. This geological diversity matters: as demand surges, the Americas’ lithium supply chain is no longer just a story about salt flats.

Salar de Atacama, Chile | 23.5°S, 68.2°W | Elevation: ~2,300m

The world’s largest and highest-grade lithium brine deposit. Operated jointly by SQM and Albemarle under Chilean government concessions, it produces roughly one-third of global lithium supply. Brine pumping in the hyper-arid Atacama has drawn intense scrutiny from Atacameno Indigenous communities and conservationists.

Salar de Uyuni, Bolivia | 20.2°S, 67.6°W | Elevation: ~3,656m

The world’s largest salt flat (10,582 sq km), holding an estimated 21 million tonnes of lithium. Bolivia’s state company YLB is developing extraction with Chinese and Russian partners, but production remains minimal due to technical challenges with high-magnesium brines and shifting political frameworks around nationalization.
