BCM Resources Corporation Provides Exploration Drilling Update For Thompson Knolls Phase 4 Campaign
BCM Resources Corporation has completed two additional diamond core drill holes of the 2026 Thompson Knolls Phase 4 exploration campaign. Hole TK17, a vertical hole collared approximately 250 m southwest of hole TK16, reached a depth of 896 m (2,935.5 feet). Hole TK18, also vertical, collared approximately 250 m southwest of TK17, reached a depth of 917 m (3,007 ft). BCM is currently drilling hole TK20, a vertical hole located approximately 460 m (1,509 ft) northeast of hole TK15, with a targeted depth of at least 1,300 m (4,265 ft). This hole is designed to test the core of the proximal skarn deposit encountered by hole TK8 in 2023. Holes TK17 and TK18 were designed to test the extension of skarn Cu-Au-Ag-Mo mineralization previously encountered in Holes TK15 and TK16. Hole TK17 confirmed the extension of skarn with some mineralization. TK18 intercepted QMP intrusion at a much shallower depth of ~300 m (~984 ft) than previously expected. QMP intrusion here carries hematitic oxidation, indicating the possibility for significant leaching of the upper parts of the intrusion that could potentially result in the formation of a chalcocite blanket at moderate depths in the vicinity of this hole. Bedrock started with polymictic breccia in marbleized dolomites at 609 m (2,000 ft). QMP intrusive with sericitic alteration was encountered in the interval from 681 m (2,235 ft) to 698 m (2,289 ft), 17 m (55 ft) represented by intensely sericitized intrusive rock. From 736 m (2,415 ft) marbleized dolomite breccia with traces of skarn and occasional blocks of black limestones dominate. Top of bedrock is oxidized, carrying secondary copper minerals (chenevixite, malachite, rosasite). Below QMP, drilling intercepted marbleized dolomite with local presence of green skarn with copper arsenites. Gradual decrease in brecciation; mostly white marbles below 792 m (2,600 ft). No presence of proximal skarn. Drilling intercepted QMP intrusive with moderately to strongly pyritic zones at 354 m (1,160 ft). A significant portion is oxidized, forming an intensely hematitic cap. Below the oxidation zone, RC chips contain fragments of quartz veinlets with pyrite and spotty chalcopyrite, suggesting potential secondary enrichment within the intrusion (verification required). QMP extends to 790 m (2,591 ft) depth of lithological contact between QMP and marbles. No evidence of skarn or ore mineralization. From 867 m (2,845 ft), dominant rocks are marbleized dolomites with black limestones and some copper oxides. No economic sulfide mineralization. BCM terminated this drillhole at 917 m (3,007 ft). Preliminary results from four drill holes indicate that the skarn mineralization extends from TK8 to TK15 and TK16; however, further to the southwest, it becomes less pronounced. Intercepted in the TK18 QMP intrusion, the sample bears sericitic alteration, apparently indicating its peripheral part. The most impressive revelation came from TK18, indicating a relatively shallow depth below the top of QMP. The upper part of QMP is heavily oxidized. RC drilling at TK18 reached 610 m (2,001 ft) through the oxidation-reduction zone into the primary QMP. Therefore, we have no drill core from this interval. But RC chips were collected and sent to ALS for analysis. Drilling continues at TK20, a hole approximately 460 m (1,509 ft) northeast of TK15, targeting the core of the proximal skarn deposit intersected by TK8 in 2023. This hole is vertical and has a target depth of at least 1,300 m (4,265 ft). Core logging and diamond saw cutting are advancing. Given the encouraging observations from TK18, it is proposed to conduct an IP/MT survey to improve targeting in the southern block of TK along geophysical anomaly 2. BCM is engaged in discussions with several contractors to complete the survey in mid-August, enabling a much more reliable selection of the location for the TK19 drill hole to test the potential of the secondary enrichment blanket in this part of the project.
