BCM Resources Corporation has completed core logging, sawing, and sample collection for diamond drill hole TK20 at its 100% owned Thompson Knolls copper, gold, and molybdenum project in Millard County, Utah.

The third and final batch of samples from the hole has been dispatched to the ALS preparation laboratory in Elko, Nevada. Due to intense potassic alteration and silicification, the core was exceptionally hard, requiring considerable time and multiple diamond saw blades to split.

Drill hole TK20 encountered intense porphyry-style quartz-molybdenum and skarn magnetite-chalcopyrite mineralization from one of the porphyry centers intersected during the project's Phase 4 drilling campaign. Visual estimates from the core show approximately 10% volume sulfides—mainly molybdenite—in quartz veinlets between 2,782 and 2,791 feet, and approximately 20% volume sulfides—mainly chalcopyrite—within a magnetite-sulfide hydrothermal breccia in green skarn from 3,644 to 3,652 feet.

Building on core preparation work that was underway in mid-August, the company has now advanced the neighboring TK21 drill hole located west of TK20. Fieldwork at Thompson Knolls also includes a completed ground-induced polarization and magnetotellurics geophysical survey. Zonge International Geophysical Services & Instruments acquired data across four lines covering three previously outlined anomalies, and those survey results are currently being processed.

“We are happy with the successful completion of intense sample preparation work of TK20 drill core. We are looking forward to the final assay results for the TK20 drill hole samples from the ALS International lab.”

— Dr. Sergei Diakov, President and CEO of BCM Resources

The exploration work at Thompson Knolls is backed by a $7,180,000 non-brokered private placement that closed in February 2026 to fund ongoing drilling and corporate purposes. Final assay results for TK20 and the processed geophysical survey data are currently pending.
