Technical Report For La Plata Project Mineral Resource Estimate

VANCOUVER – Metallic Minerals Corp. has filed the National Instrument 43-101 technical report (NI 43-101) – Allard Cu-Ag-PGE-Au Porphyry Deposit, La Plata Project, Southwestern Colorado.
Greg Johnson, Chairman and CEO, said, “The recently filed 2026 NI 43-101 Mineral Resource Estimate at the La Plata project marks a major milestone for the Company. The updated estimate expands the Inferred resource tonnage by approximately 23% to 181.4 Mt at 0.36% copper equivalent, containing 1,307 Mlbs of copper and 17.0 Moz of silver (1,455 Mlbs CuEq). Importantly, this updated estimate incorporates platinum, palladium and gold for the first time, with a 45.4 Mt subset now reporting 91,000 oz Pt, 121,000 oz Pd and 60,000 oz Au totaling ~272,000 oz of platinum group elements plus gold, which enhances the overall value and metal diversity of the deposit.
The La Plata project represents a rare large-scale U.S. based mineral system hosting many critical minerals identified as strategically important to U.S. supply chains. Located in southwest Colorado, the project is an alkalic porphyry copper-silver-PGE-gold system hosting a broad suite of critical minerals within accessory phases including magnetite, fluorapatite, titanite, and zircon. These minerals collectively host light and heavy rare earth elements along with six additional priority critical minerals including gallium, scandium, vanadium, titanium, zirconium and hafnium-many of which face severe U.S. supply vulnerabilities or 100% import dependence.”
