Stardust Power Advances Execution Readiness at Muskogee Lithium Refinery
Rhea-AI Summary
Stardust Power (NASDAQ: SDST) has started site engineering at its Muskogee, Oklahoma lithium refinery, moving from FEL-3 front-end engineering into execution-level design. Brown & Root will conduct geotechnical borings and subsurface investigations based on the completed three-dimensional plant model.
The work will generate site-specific data for civil design, structural foundations, procurement and construction planning. The Muskogee refinery is designed to produce up to 50,000 metric tons per year of battery-grade lithium carbonate and is expected to be among the largest U.S. lithium refining facilities upon completion.

Positive project or partnership updates have sometimes seen aligned price gains, while larger financing or registration steps have coincided with negative reactions.
Over the past few months, Stardust Power has focused on building out its Muskogee lithium refinery and related funding. News included DOE-backed research participation on Jun 2, 2026, Q1 results and Muskogee progress on May 14, 2026, and multiple registration and investment frameworks supporting the refinery’s 50,000 tpa design. Some constructive project milestones, like expanded feedstock and institutional investment frameworks, previously coincided with share price declines, underscoring investor focus on financing risk and dilution alongside execution progress.
Regulatory & Risk Context
An effective S-3 shelf filed on 2026-04-08 allows Stardust Power to offer up to $100,000,000 of various securities via future prospectus supplements. Multiple 424B3 filings in May 2026 highlight active use of registration capacity and emphasize disclosed going-concern risk and reliance on additional financing.
Market Pulse Summary
This announcement details advancement from FEL-3 into execution-oriented engineering at the Muskogee refinery, including geotechnical work to support site civil and foundation design for a planned 50,000 tpa lithium carbonate facility. It follows recent financing and registration activity, including a $100,000,000 shelf and multiple resale prospectuses that highlighted going-concern risk. Investors may track future updates on construction timing, funding drawdowns under existing facilities, and how execution milestones interact with potential additional offerings under the shelf.

GREENWICH, Conn., June 16, 2026 (GLOBE NEWSWIRE) -- Stardust Power Inc. (NASDAQ: SDST) ("Stardust Power" or the "Company"), an American developer of battery-grade lithium carbonate, today announced the commencement of site engineering activities at its lithium refinery site in Muskogee, Oklahoma, marking an important step in advancing 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.
