BCM completes core cutting and sampling of TK20 porphyry/skarn mineralized drill core

Vancouver, British Columbia--(Newsfile Corp. - September 3, 2026) - BCM Resources Corporation (TSXV: B) ("BCM" or the "Company") is pleased to announce that core logging, sawing, and sample collection of core from diamond drill hole TK20 at its 100% owned Thompson Knolls (TK) project has now been completed. The third and final batch of samples has been sent to the ALS preparation lab in Elko, Nevada. Due to intense potassic alteration and silicification of the rock encountered in this hole, the core was exceptionally hard and required considerable patience and multiple diamond saw blades to split.

Intense porphyry-style quartz-molybdenum and skarn magnetite-chalcopyrite mineralization from TK20 comes from one of the porphyry centers intersected in the Phase 4 drilling campaign at TK (see Figures 1 and 2 below). Currently, the Company is advancing its TK21 drill hole, located west of TK20 (see the Company news release dated August 17, 2026).

Fieldwork at TK continues. In parallel with drilling of hole TK21, BCM just completed its geophysical survey at Thompson Knolls. IP/MT data were collected by Zonge International Geophysical Services & Instruments. Data were collected from four lines covering all three previously outlined geophysical anomalies 1, 2, and 3 (see BCM presentation on the Company website) and are currently being processed.
