Sigma Lithium Resources is developing a world-class hard rock lithium project in Brazil. The company runs a green and sustainable mining business, operating within full corporate governance and transparency standards.
Backed by serious green fund investors, Sigma was created to contribute to the development of clean sustainable energy with plans to play a role in the global lithium battery supply chain and the flourishing electric vehicle industry.
Brazilian subsidiary Sigma Mineração has 28 concessions with full mining licenses in mines that have historically produced lithium. Sigma's concessions encompass one of the highest grade hard rock spodumene pegmatites in the world and span more than 18,000 hectares.
Sigma Value Proposition
Lithium is the answer to the future of clean energy and will have a significant role in reducing the global carbon footprint and dependence on fossil fuels. Backed by major green fund investors, Sigma operates a truly green open-cast low-risk mining operation that is focused on the sustainable management of resources.
As part of this, we are conducting an environmental impact study to develop a clean, safe and modern industrial-scale operation in the Vale do Jequitinhonha, Minas Gerais state, Brazil, that will adhere to best green mining practices.
Sigma is developing an industrial-scale green mining operation in the Vale do Jequitinhonha, Minas Gerais state, Brazil. The project will bring direct and indirect jobs to the local community and contribute to its economic development. Environmentally, we will adhere to best green mining practices and contribute to a cleaner and greener future for the community and Brazil.
The mines are located in the Vale de Jequitinhonha region between the cities of Araçuaí and Itinga.
Lithium will substitute fossil fuels in vehicles, make renewable energy such as wind and solar sustainable and underpin the future of clean energy.
Sigma was created by green investors to find significant lithium deposits and contribute to the global lithium battery value chain to help reduce pollution. Brazil, for example, has the third-and sixth-largest bus and car fleets respectively in the world and consequently some of the most polluted cities globally.
It is Sigma’s goal to become a key building block toward the manufacture of lithium batteries in Brazil, changing the future of industry and power storage in this country, contributing to a cleaner Brazil.
Brazil Bus Fleet
With nearly 400,000 buses in circulation in Brazil, Latin America’s biggest economy has the third-largest bus fleet in the world after China and India. Consequently, Brazil has some of the most polluted mega cities. Sao Paulo and Rio de Janeiro are ranked alongside the likes of Shenzen and not too far behind Shanghai but way ahead of Los Angeles and New York, according to World Health Organization statistics.
The expectation is that the air quality will change dramatically with the introduction and distribution of electric buses given that diesel-fuelled buses today represent approximately 43% of all vehicle emissions in Brazil.
Brazil is committed to reducing emissions by 37% in 2025 and by 45% in 2030.
A whole industry worth billions of dollars in investments will be borne thanks to lithium hard rock, providing thousands of jobs and assuring a green and sustainable future for the auto sector in Brazil – one of the biggest in the world. This is a vision that serious green investors first had in mind when they created Sigma, which was established to find significant high-grade lithium deposits around the world, representing a two-year journey that ended in the Vale de Jequitinhonha, Minas Gerais state.
In early 2018, there were a little more than two million electric cars in circulation in the world. This compares starkly to the 1.1 billion cars travelling on today’s roads. By 2040, the global car fleet is expected to nearly double to two billion cars, according to research house Bernstein.
Thankfully, governments around the world are working on new laws to ensure that petrol, diesel and flex-fuelled cars are substituted with lithium-battery-powered environmentally-friendly and quiet cars between 2030 and 2040. As lithium battery technology continues to evolve, consumers will also potentially have access to more economical cars as engines will be cheaper to build and last longer.
Sigma is developing a world-class industrial-scale hard-rock lithium project. The significant deposits in Brazil can be counted among some of the highest-grade spodumene pegmatites in the world.
The open-cast low-risk mining operation is a story six years in the making thanks to an international team of expert geologists and miners, who spent two years searching for the right high-grade lithium mine before buying a concession in Brazil and investing a further four years in exploring and mapping the resources at the Vale de Jequitinhonha site in the state of Minas Gerais.
Sigma is focused on 10 high-grade hard-rock lithium pegmatites, nine of which were past-producing lithium mines. Sigma is developing its first industrial-scale lithium mine at the historical Xuxa mine.

“Our goals are to open the industrial-scale mine in late 2019 and produce more than 220,000 tons of spodumene in its first full year of operation in 2020. Sigma currently has a NI43101 compliant resource of 13.5 million tonnes at 1.56% Li2O at the Xuxa mine. Sigma has a fast-mover advantage in Brazil and has already successfully produced high-quality battery-grade spodumene concentrate above 6% Li2O,” says CEO of Sigma Mineração Itamar Resende.
Sigma has already acquired a pilot plant to advance metallurgical and product testing further in the mining town of Aracuai and mining-friendly state of Minas Gerais that is well served by infrastructure, roads, hydroelectric power, water and the port of Vitoria in neighbouring Espirito Santo state.
Ultimately, Sigma’s project is in a race to production to meet local Brazilian and global lithium demand. Xuxa is one of six priority lithium deposits sites at Grota Do Cirilo. The mining company has identified more than 200 pegmatite bodies on all properties.
