A huge cache of critical minerals found in Utah may be the largest in the US

Ionic Minerals Technology announced a large, clay-hosted discovery of 16 critical minerals and rare earths at its Silicon Ridge site in Utah—including halloysite, gallium and germanium—which third-party testing confirmed and which the company says is easier and lower-impact to extract than hard-rock ores. With state leases covering more than 4,000 acres (and a request for an additional ~3,700 acres), permits in place, and a 74,000 sq ft processing plant in Provo, Ionic MT says it can rapidly supply materials for EV batteries, semiconductors and defense while generating local jobs and royalty revenue for Utah schools. The find, touted by state leaders and of interest to federal officials, could help diversify U.S. critical-minerals supply away from China, though commercial-scale reserves, extraction economics and confidential permit terms have yet to be publicly detailed.

Analysis

Ionic Minerals Technology reported a clay-hosted discovery at its Silicon Ridge site in Utah containing 16 critical minerals including halloysite, gallium and germanium, with third-party testing confirming consistent metal distributions across samples; the deposit is reported as suspended in clay rather than hard rock, which the company says enables easier extraction and lower environmental impact. The firm already operates a 74,000-square-foot processing plant in Provo, holds an initial 4,053-acre lease (seeking an additional ~3,700 acres), and has a permit from the Utah Division of Oil, Gas, and Mining (permit terms confidential), with state royalties set at $13 per acre per year and $1.60 per ton or 10% of gross value, whichever is greater.

The discovery is strategically significant because China currently supplies roughly 60% of rare-earth production and 90% of processing; Utah officials and federal parties have expressed interest, and Ionic MT positions the find as a potential domestic source for EV batteries, semiconductors and defense supply chains. The company claims minimal waste extraction methods and no explosives or chemicals, and projects local job creation and school revenue from lease payments.

Material uncertainties remain: commercial-scale reserves, detailed metallurgy, unit economics and confidential permit terms are not publicly disclosed, and any federal support or offtake agreements are unspecified. Market impact is moderately positive as a supply-diversification signal, but valuation and investment decisions should await audited resource estimates, scalable processing proof points and clear regulatory timelines.

Key Decisions for Investors

• Require audited, independent resource and metallurgical reports before increasing exposure or making material investment decisions
• Monitor disclosure of permit terms, lease expansion results and any announced federal funding or offtake agreements as primary catalysts for revaluing the opportunity
• Consider limited, tactical exposure to specialists in critical-minerals processing or halloysite applications if short-term supply tightness emerges, but cap position size until economics and scalability are demonstrated
• Price and hedge for execution and regulatory risk by tracking timelines for permitting, community/environmental approvals and production ramp; avoid aggressive commitments while key data remain confidential
