BCM Resources Corporation (TSXV: B) (“BCM” or the “Company”) is pleased to announce that diamond drill hole TK20, currently in progress, has encountered over 550 m of strongly mineralized porphyry and intercalated skarn mineralization at its 100% controlled Thompson Knolls project, Utah. Hole TK20 is a vertical drill hole collared 208 m northeast of discovery hole TK8 that intercepted 510 ft (155.4 m) of mineralized skarn grading 0.66% Cu, 0.12 gpt Au, and 7.4 gpt Ag…
Beyond the Headline
BCM Resources reported that Hole TK-20 intersected over 550m of strong porphyry-skarn mineralization at its 100% controlled Thompson Knolls Project in Utah. Hole TK-20 is a vertical drill hole collared 208m northeast of discovery hole TK8 that intercepted 510 ft (155.4 m) of mineralized skarn grading 0.66% Cu, 0.12 g/t Au and 7.4 g/t Ag. Assays on this hole are pending.
The Company reports that “TK20 is unquestionably the most strongly mineralized hole drilled to date at Thompson Knolls. Mineralization commences at the top of bedrock at a depth of 1,930 ft (588.4 m) and persists to the current depth of 4,062 ft (1,238.4 m). Given the strong mineralization observed in core, the Company is aggressively pushing this hole deeper.” Approximately 70% of the mineralized core encountered to date is reported to be comprised of mineralized intrusive rocks, both quartz monzonite porphyry and latite porphyry. These rocks are commonly strongly potassically altered and intensely and complexly stockwork-quartz-veined. The nature of this alteration and veining is interpreted to suggest TK20 has encountered the high-temperature core of a large, strong porphyry mineralizing system. The remaining 30% of the core from TK20 is comprised of mineralized magnetic skarn that is intercalated with the porphyry phases. In many places, abundant sulfides including chalcopyrite and pyrite are associated with magnetite mineralization. Locally, molybdenite is also present in skarn. The Company is currently drilling another vertical hole, TK21, collared 250 m west-southwest of TK20. This hole will effectively twin previous hole TK5, a hole drilled in 2022 that was abruptly terminated in mineralization due to bad ground conditions. The bottom of TK5 encountered magnetic skarn mineralization similar to that observed in TK20.
Final interpretation of the significance of Hole TK-20 awaits assay results however BCM’s interpretation that they are approaching the high temperature core of a large porphyry system appears quite reasonable. Hole TK-21 will be a very important hole to potentially confirm both the lateral and vertical extent of the porphyry system intersected in Hole TK-20. Things to look for in results from Hole TK-20 are the level of Cu grades through substantial portions of the porphyry, whether grades of Mo increase with depth and whether Cu-Au zones correlate with chalcopyrite enrichment or the first appearance of bornite.
