Sigma Lithium Corp. is making significant progress on the expansion of its Greentech Industrial Plant in Minas Gerais, Brazil, with construction advancing on schedule and within budget. The company remains on track to double its lithium concentrate production capacity by 2025, with commissioning of the new plant set to begin in Q4 2025.
Sigma Lithium has successfully completed:
✅ 100% of the foundation earthworks for its second lithium beneficiation plant.
✅ The first cement pour and civil works, including water drainage infrastructure.
✅ Procurement and contractual negotiations for key equipment, with deliveries expected to begin in mid-2025, followed by the assembly of mechanical structures.
The company has secured a USD $100 million credit line from BNDES (Brazil’s Development Bank) to fully fund the construction, allowing the project to move forward despite the current lithium market cycle.
Once operational, the expansion will increase Sigma’s annual lithium concentrate production from 270,000 tonnes to 520,000 tonnes by 2026. An interim boost is expected in 2025, with output rising to 300,000 tonnes as the second plant ramps up.
Sigma’s ability to scale operations efficiently is supported by its existing infrastructure, which reduces capital expenditure intensity and enables the company to control costs while accelerating construction timelines.
💬 “As one of the world’s lowest-cost lithium producers, we are well-positioned to leverage economies of scale, further enhancing cost efficiency and solidifying our role in the global lithium supply chain,” the company stated.
Currently, 100 workers are engaged in the construction phase, with plans to expand to 1,000 at peak construction. Sigma Lithium has also accelerated its Homecoming Program, creating a training center for heavy machinery operators in a neighboring community, reinforcing its commitment to social and environmental sustainability.
Sigma Lithium continues to strengthen its position as a leading supplier of carbon-neutral, socially responsible lithium to support the growing global demand for electric vehicle batteries. As the lithium market expands, the company remains strategically positioned to meet future demand while maintaining cost efficiency and sustainability leadership.
