Anson Stretches Green River Resource 650% to 773,000t LCE

Why It Matters

The massive resource boost positions Green River as a leading U.S. lithium play, enhancing Anson's ability to capture market share in the fast‑growing battery supply chain. It also strengthens the company’s financing narrative and could accelerate development timelines.

Key Takeaways

• Green River MRE now 773,000 t LCE after 650% increase.
• Indicated resources rose 863% to 183,000 t LCE.
• Inferred resources grew 602% to 590,000 t LCE.
• Anson aims >1 Mt LCE MRE, leveraging new mineral rights.

Pulse Analysis

Lithium demand is surging as automakers and energy‑storage firms chase cheaper, higher‑capacity batteries. The United States is eager to develop domestic sources to reduce reliance on South‑American brines, and Utah’s Green River basin offers a geologically favorable setting. Anson’s latest resource estimate places the project among the largest U.S. lithium deposits, potentially supplying a significant portion of the projected 1.5 million‑tonne annual demand by 2030.

The 650% resource uplift stems from an intensive drilling campaign that incorporated data from the Bosydaba #1 and Mt Fuel‑Skyline Geyser wells, alongside new mineral‑rights acquisitions. By refining stratigraphic thickness models and confirming higher brine lithium concentrations, Anson upgraded both indicated and inferred categories, delivering an 863% jump in the higher‑confidence indicated tier. This methodological rigor, aligned with JORC standards, boosts investor confidence and may lower the cost of capital for future development phases.

Looking ahead, Anson’s strategy hinges on securing additional permits to expand the resource beyond the 1 Mt LCE threshold without further drilling—a claim supported by the extensive oil‑and‑gas legacy data in the region. If successful, the company could fast‑track a pilot extraction program, positioning itself to partner with battery manufacturers seeking secure supply. The upgrade also puts pressure on competing U.S. projects to demonstrate comparable resource confidence, potentially reshaping the competitive landscape of North American lithium production.
