Sigma Lithium Corporation (NASDAQ: SGML) announced it has resumed sales of high-grade premium lithium oxide concentrate and completed its first sale of lithium fines, according to a company statement.

The company expects to generate gross revenues equivalent to approximately 28,000 tonnes of high-purity premium lithium oxide concentrate at a grade-adjusted price of $1,712 per tonne in the first quarter of 2026.

Sigma Lithium completed an inaugural sale of 400,000 tonnes of high-purity lithium fines for delivery at its plant at a fixed price of $50 per tonne. The transaction is expected to generate approximately $20 million in profit.

The company retains an inventory of approximately 300,000 tonnes of high-purity lithium fines at its plant, which it expects to generate at least an additional $15 million in profit.

"The resumption of sales of high-grade premium lithium oxide is in accordance with the outlook we highlighted at our investor presentations this year," said Ana Cabral, Co-Chairperson of Sigma Lithium.

The company said these results stem from industrially beneficiating its dry-stacked tailings and inventory of raw materials into both high-purity premium lithium oxide fines and high-purity lithium oxide.

Sigma Lithium operates what it describes as one of the world's largest lithium production sites at its Grota do Cirilo operation in Brazil. The company currently has nameplate capacity to produce 270,000 tonnes of lithium oxide concentrate annually and has begun construction of a second plant to double production capacity.

The information is based on a company press release statement.
