Our Company

Mr. Wes Roberts, P.Eng., a member of the technical committee of the Company, is the “qualified person” under NI 43-101 who reviewed and approved the technical information included on the website.

Company Business

The Company, through its indirectly wholly-owned subsidiary Sigma Mineração S.A., is developing, with an environmental sustainably ESG focused strategy, the largest hard rock lithium deposits in the Americas, located in its wholly-owned Grota do Cirilo Project in Brazil (the ”Project”) with the goal of participating in the rapidly expanding global supply chain of electric vehicles (“EVs”).

Based on the Feasibility Study Report, the Company plans to produce 270,000 tonnes annually of battery grade lithium concentrate lithium (37,000 tonnes of lithium carbonate equivalent (“LCE”)) in Production Phase 1 and expects to be amongst the world’s lowest-cost producers. Adding Production Phase 2 and 3 production will be increased to 766,000 tonnes (104,000 tonnes of LCE) annually.

The Company is currently commissioning of our environmentally friendly, fully automated, dense media separator (“DMS”) production plant that applies proprietary algorithms to digitally control the dense media (the “Production Plant”). The Production Plant will be vertically integrated into the Company´s mining operations, exclusively utilizing as feedstock the high purity spodumene ore with exceptional mineralogy from the Project. The Production Plant will process the spodumene ore into a high purity 5.5% battery-grade lithium concentrate engineered to the specifications of its customers in the lithium-ion battery supply chain for EVs.

The first phase of the production (“Production Phase 1”) will utilize as feedstock spodumene from the Project’s Xuxa deposit. The next production phase of the Project (“Production Phase 2”) would be increased production including feedstock from the Project’s Barreiro deposit.

Since 2018, the Company has been producing low carbon high purity lithium concentrate at an on-site demonstration plant with the objective to ship samples to potential customers for product certification and testing. This demonstration production has been an important part of the successful commercial strategy of the Company for its low carbon high purity lithium.

The Company plans to achieve net-zero targets by 2024, partly as a result of its strategic decision to pursue generation of carbon credits through “in-setting” carbon credits (preserving and developing the agroforestry systems within its regional ecosystem).

In order to secure a leading position supplying the clean mobility and green energy storage value chains, the Company has adhered consistently to the highest standards of environmental, social, and governance (“ESG”) practices, which were established as part of its core purpose at inception in 2012. Its production process will be powered by clean energy and the Company will use state-of-the-art water recirculation circuits in its processing combined with dry stacking tailings management. The DMS process of the Production Plant does not utilize hazardous chemicals, as a result, its tailings are 100% recyclable into ancillary industries, such as ceramics.

The Company is currently undergoing an independent assessment of its net carbon footprint, conducting an independent ISO 14000 compliant audit of its life cycle analysis together with an independent expert validation of its carbon credits generated by its internal preservation, reforestation, and compensation forestry programs. The Company expects to complete this workstream in the second half of 2021.

Lithium Properties

The Project comprises four properties owned by SMSA and is divided into the Northern Complex (the Grota do Cirilo, Genipapo and Santa Clara properties) and the Southern Complex (the São José property). The Project consists of 27 mineral rights (which include mining concessions, applications for mining concessions, exploration authorizations, and applications for mineral exploration authorizations) spread over 191 km2. The Project area includes nine past-producing lithium mines and 11 first-priority exploration targets. Granted mining concessions are in good standing with the Brazilian authorities. The Project is located in Northeastern Minas Gerais State, in the municipalities of Araçuaí́ and Itinga, approximately 25 km east of the town of Araçuaí́ and 600 km northeast of Belo Horizonte.

Our mission is to enable electric vehicle industry growth by becoming one of the largest, lowest cost and lowest carbon producers of environmentally sustainable lithium products in the world.

Our goal is to reach net-zero by 2024.
