BCM Resources Logs Roughly 1,000 ft of Copper Skarn in Hole TK21 at Thompson Knolls, Utah

304.8 m copper skarn, down-hole length in TK21 (about 1,000 ft) 140 m sub-interval with chalcopyrite above 1% by volume (about 460 ft) 900–1,205 m depth range of copper mineralization in the logged hole 2 holes awaiting assays: hole TK20 at the lab, and hole TK21 now being sampled BCM Resources Corporation (TSXV: B) has completed diamond drill hole TK21 at its 100%-controlled Thompson Knolls project in Millard County, Utah, intersecting copper skarn over a down-hole length of approximately 1,000 ft (304.8 m). On October 15th, after a midday trading halt, the company reported the hole results. Assays for the hole are still pending. The results are visual and incredibly encouraging: a sub-interval of approximately 460 ft (140 m) carries chalcopyrite at more than 1% by volume, and the company describes disseminated chalcopyrite across multiple skarn intervals. True width was not stated in the release. Standard diamond drilling core size or NQ core from TK21 at 3,944 ft encountered intensely brecciated skarn with abundant sulfides and visible chalcopyrite. TK21 is a vertical hole drilled from the same platform as TK5, which intersected copper skarn at 2,758 ft (840.6 m) before it was lost to difficult ground. TK21 reached 4,241 ft (1,293 m). Copper mineralization began at approximately 2,952 ft (900 m) in dolomitic marbles and continued to approximately 3,952 ft (1,205 m), the interval that contains the skarn intercept. BCM previously reported 0.66% Cu over 155.4 m in hole TK8 on the same project. "We are happy to report that hole TK21 has confirmed the presence of significant copper skarn mineralization like both TK8 and TK5 to the west. Although we must await assay results to confirm grades, visual observations of disseminated chalcopyrite across multiple skarn intervals intersected by hole TK21 give us encouragement that we are near the proximal skarn environment." Dr. Sergei Diakov, President and CEO, BCM Resources The geology The hole reached bedrock at 1,867 ft (569 m) beneath fanglomerate cover. The upper bedrock was brecciated and limonitized Guilmette limestone, passing downward into Simonson dolomites and dolomitic marbles, which host the copper mineralization. At 4,086 ft (1,245.4 m) TK21 entered the Eureka quartzite, which carried discontinuous zones of sulfide mineralization. The company tried to reach the underlying Pogonip carbonate formation to test for more skarn, but the hole was lost in the quartzite at 4,241 ft (1,293 m). What comes next Two holes are now waiting on assays. Results from TK20 are still at the laboratory, held up partly by lab backlogs and by the multiple assay techniques needed for molybdenum, copper, gold, silver and rhenium. TK21's core is being logged, sawn and sampled. BCM said assays will be released when they return from the lab. Drilling moves to TK22, an inclined hole from the same platform at an azimuth of 80° and an inclination of 75°, aimed toward TK20. It is designed to test for displaced porphyry copper core mineralization and for proximal skarn along the projected margin of the porphyry molybdenite core encountered in TK20. BCM has also completed IP and MT geophysical surveys over the project. Its contractor is processing the data into 3D models that the company plans to use to design its Phase 5 drill program, with results to come in a later news release.
