Important construction step taken by Stardust Power refinery

Lithium developer Stardust Power Inc. announced it has started site engineering activities at its refinery in Muskogee, calling it an “important step” in moving the refinery’s transition from front-end engineering into execution-level design.

Brown & Root, a leading EPC firm, has been engaged to perform the work, representing another important step in advancing the refinery’s detailed engineering. The geotechnical work will include a series of site borings and subsurface investigations based on the refinery’s completed Front-End Loading Level 3 (“FEL-3”) engineering design and current three-dimensional plant model. The work will evaluate subsurface conditions across key facility locations and translate the refinery’s completed FEL-3 engineering into site-specific design data supporting detailed engineering, procurement, foundation engineering and future construction planning. The results will provide critical inputs for site civil design, structural foundation design and infrastructure planning, further advancing the project toward execution.

“With FEL-3 complete, we are now advancing the engineering activities that move the project from design toward execution,” said Ken Pitts, Director of Construction and Contracts at Stardust Power. “This work provides critical site-specific information that supports foundation design, construction planning and future engineering. Each step further reduces execution risk and helps position the refinery for efficient execution and delivery. We are pleased to be working alongside experienced engineering and construction partner Brown & Root as we continue advancing the project.”

Roshan Pujari, Founder and Chief Executive Officer of Stardust Power, added: “Large-scale industrial projects are built through disciplined engineering and systematic risk reduction. These activities convert completed engineering into site-specific engineering data while further advancing the refinery toward construction. As we continue progressing the project, our focus remains on increasing engineering certainty, reducing execution risk and creating long-term value for our shareholders.”

The Muskogee refinery is designed to produce up to 50,000 metric tons per annum of battery-grade lithium carbonate and is expected to be one of the largest lithium refining facilities in the United States upon completion.

Stardust Power is building one of America’s largest battery-grade lithium carbonate refineries in Muskogee, Oklahoma, strategically located in the center of the United States’ growing energy and manufacturing corridor. The refinery is expected to have production capacity of up to 50,000 metric tons per annum and addresses the critical shortage of U.S. lithium refining capacity. The Company’s mission is to strengthen America’s critical mineral independence by building the domestic infrastructure needed to power the nation’s energy, manufacturing and technology future.
