Sigma Lithium shares surge 14.43% intraday as lithium mining sector trends upward on supply concerns and resumption of concentrate sales.

Sigma Lithium surged 14.43% intraday as renewed mining operations and analyst upgrades drove optimism. The company announced resumption of high-grade lithium oxide sales, projecting $1.712/tonne revenue for 28,000 tonnes in Q1 2026, alongside a $20 million fixed-price sale of 400,000 tonnes of lithium fines. BofA Securities reiterated a $14 price target and "Neutral" rating, citing improved liquidity from concentrate sales and operational restarts. The stock’s rally aligned with broader lithium sector strength, as a Chinese mine shutdown raised supply concerns, lifting industry peers. Despite earlier volatility, the move reflected confidence in Sigma’s sustainability-driven production and near-term cash flow potential.
