Sigma Lithium Corporation completed its first sale of 100,000 tonnes of high‑purity lithium fines, a by‑product of its Greentech industrial plant. The transaction generated $11 million in net revenue, with the fines sold at an average price of $125 per tonne—below the Shanghai Metals Market index range of $150 to $230 for material containing 1.2%‑1.5% lithium oxide but still a notable revenue source.
The sale is part of the company’s waste‑stream monetization strategy. Sigma has produced an additional 850,000 tonnes of high‑purity lithium fines at the plant, turning a low‑value tailings stream into a new cash‑flow stream that complements its core lithium oxide concentrate sales and reinforces its cost‑leadership model.
In addition to the sale, Sigma closed a working‑capital revolving facility, with the first tranche of $5 million secured. The facility provides liquidity to support the ramp‑up of Greentech Plant 2 and the remobilization of mining personnel and equipment, which is expected to conclude in January 2026. The company also appointed former Brazilian Minister of Agriculture Katia Abreu as an independent board member, underscoring a focus on governance and financial flexibility.
Guidance for 2026 output will be released once production resumption reaches a steady state in the first quarter. While analysts remain divided—some maintaining sell ratings due to profitability concerns and others bullish on the company’s low‑cost position—market reaction has been mixed. Operational progress and the new financing are viewed as positive, but lingering financial risks temper enthusiasm.
CEO Ana Cabral highlighted the company’s resilience in volatile lithium markets, noting that the fines sale and working‑capital facility strengthen cash flow and support expansion plans. The move signals confidence in the company’s ability to scale while maintaining a low‑cost advantage.
