Stardust Power shares surge 10.32% intraday after securing final air permit for Muskogee lithium refinery.

Stardust Power (NASDAQ: SDST) surged 10.32% intraday following the announcement that it secured the final air quality construction permit for its Muskogee, Oklahoma, lithium refinery. The permit, issued by the Oklahoma Department of Environmental Quality, clears regulatory hurdles for the project, which is among the largest lithium refining facilities planned in the U.S. The approval validates the refinery’s compliance with environmental standards, including a closed-loop water system and minor-source emissions classification, reducing regulatory timeline risks. This milestone positions the company to advance toward a final investment decision and construction, pending financing, with the facility expected to produce 50,000 metric tons annually of battery-grade lithium carbonate. The news, widely reported across multiple sources, underscores progress in establishing a domestic lithium supply chain, aligning with growing demand in North America’s clean energy and EV sectors.
