WHITEMOON
High-grade, high-purity magnesite from the American Southwest - restoring domestic supply security for a critical mineral.
A domestic source for a global-critical metal.
Whitemoon Magnesium is a US-based exploration and development company focused on 100%-owned historical claims in San Bernardino County, California - including the historic Whitemoon Magnesite Deposit and the El Capitan Deposit.
The Whitemoon Magnesite Deposit sits on 55 acres of private patented land, surrounded by 200 acres of placer / lode claims near the Arizona and Nevada borders.
Whitemoon is a historic mining site with visible magnesite material at surface, open at depth, and clear evidence of past operations - a high-grade, high-purity magnesite deposit on US soil.
San Bernardino County is a mining-friendly region with 90+ active mines, including Equinox Gold’s Castle Mountain Mine (60km) and MP Materials’ Mountain Pass Rare Earth Mine (100km).
Magnesium is a listed critical mineral in both the US and EU - vital to aerospace, automotive and defense. China dominates ~90% of global supply while US production is effectively zero. Whitemoon aims to help restore domestic supply security.
