SGML · XNCM · Other Industrial Metals & Mining · Brazil
Sigma Lithium Corporation is a materials company focused on the exploration, development, and production of lithium deposits in Brazil. The company holds a 100% interest in the Grota do Cirilo, Genipapo, Santa Clara, and São José properties, encompassing approximately 185 square kilometers in Brazil’s Minas Gerais state. Sigma Lithium’s core purpose is to supply high-purity, environmentally sustainable lithium concentrate, a critical input for lithium-ion batteries used in electric vehicles and energy storage systems. The company serves the burgeoning global lithium-ion battery supply chain, positioning itself as a key player in advancing the electrification of transportation and the global energy transition. A distinct hallmark of Sigma Lithium’s operations is its commitment to environmental and social sustainability, highlighted by initiatives targeting net-zero emissions and minimizing the use of hazardous materials, potable water, and tailings dams. These practices set a new benchmark for responsible lithium production. By delivering "green lithium" from one of the world’s largest hard rock lithium projects, Sigma Lithium Corporation plays an essential role in supporting the growth of the electric vehicle sector and enabling more sustainable battery technologies.

Supply Chain
Lithium Supply Chain
The lithium supply chain is shaped by three structural constraints that most commodity systems do not face simultaneously: extraction methods diverge so fundamentally that brine evaporation and hard-rock mining produce different timelines, geographies, and cost structures from the same element; chemical refining is concentrated in China regardless of where lithium is mined; and demand grows on EV product cycles while new mine development takes five to seven years, creating a timing mismatch the system cannot resolve through price alone.
Rare Earth Elements Supply Chain
The rare earth supply chain is governed by three structural constraints that most industries never encounter: rare earth elements occur together in ore and cannot be mined individually, separation requires toxic acid-based processes that produce radioactive waste, and China controls roughly sixty percent of mining and ninety percent of processing capacity worldwide.
Copper Supply Chain
The copper supply chain is shaped by three structural constraints that compound over time: ore grades are declining, forcing more energy and processing per ton of output; smelting and refining capacity is concentrated in China, which processes roughly forty percent of global copper; and new mines take ten to fifteen years from discovery to production, meaning supply cannot respond to demand on any timeline shorter than a decade.
