BCM Resources Corp Completes Deepest Diamond Drill Hole to Date at Thompson Knolls

Vancouver, April 27, 2026 - BCM Resources Corp. (TSXV: B) ("BCM" or the "Company") is pleased to announce completion of its first diamond core drill hole of the 2026 Thompson Knolls Phase 4 exploration campaign. Hole TK15, a vertical hole collared approximately 250 m southwest of Hole TK8, reached a depth of 3,995.5 feet (1,219 m), a record depth for the project (see Figure 1). This hole was designed to test the extension of skarn Cu-Au-Ag-Mo mineralization previously encountered in Hole TK8 (please refer to the Company's news release dated May 24, 2023). Drilling contractors, National EWP (undertaking reverse circulation pre-collar holes), and TonaTec Exploration LLC (completing diamond core tails), achieved completion of TK15 in record time, reaching the targeted depth in 38 days.

Highlights of TK15:

• Extensive intervals of pyroxene-diopside skarn were encountered within strongly marbleized dolomites beginning at the top of bedrock at approximately 1,950 feet (594.5 m) and continuing to a depth of approximately 3,900 feet (1,188.7 m) at which point quartzite became the dominant lithology. Importantly, the intensity of skarn appears to increase with depth. This increase in skarn intensity observed in Hole TK15 provides BCM's geologists with important information about the vertical component for vectoring within the system.

• Mineralization, represented by a magnetite-pyrite-chalcopyrite mineral assemblage of variable intensity, occurs in breccias, veinlets, and in disseminated form within multiple intervals of skarn.

• The top of the bedrock, approximately 300 ft (91 m), is heavily oxidized, perhaps due to a nearby structure allowing deep penetration of oxidizing groundwater in this area. The intensity of iron oxide formation in this zone provides BCM geologists with a reason to believe its origin is sulfide weathering.

• Thin fault-bounded dikes of silicified quartz-monzonite porphyry and silicified pyritic latite were encountered within marbles below the zone of oxidation.

• The most intense zones of mineralization contain up to 20% sulfides, with chalcopyrite accounting for up to 5% of the mineralized rock. These intervals are local and do not represent the full extent of the skarn-hosted mineralization.

• A tectonic shear zone, or fault, with fragments of quartzites began at approximately 3,900 feet (1,188.7 m) depth and continued to TD at 3,999.5 ft (1,219 m) depth.

Update on 2026 Thompson Knolls Drill Campaign:

Pre-collars for Holes TK16 and TK17, 250 m southwest of TK15 and a further 250 m, respectively, have been completed. TonaTec Exploration LLC is currently moving its diamond core rig to pre-collar TK16, where a deep core tail will be completed over the coming weeks.

National EWP is currently commencing pre-collar TK18, located approximately 250 m southwest of Hole TK17.

Core logging and diamond saw cutting of TK15 are advancing as the 2026 Phase 4 drill campaign continues.

Sergei Diakov, BCM's President and Chief Executive Officer, states: "We are excited that Hole TK15 confirms the extension of skarn mineralization southwest of TK8. Our team views this as an encouraging indication that we are dealing with a sizeable, mineralized trend. We are especially impressed by the technical performance of both drilling contractors, National EWP and TonaTec Exploration LLC, which have convincingly demonstrated their ability to reach targeted depth within a relatively short period of time."
