(TSXV: BRC) (the \"Company\" or \"Blackrock\") is pleased to announce that drilling has encountered the strike extension of the Denver vein system 650 metres north of the DPB resource area on its 100% controlled Tonopah West project, located in the Walker Lane trend of Western Nevada. Drilling is continuing at the Tonopah West project with five (TW22-117 to -121) step-out drillholes completed to date. Drillholes TW22-119 and TW22-120 intersected the Denver vein system approximately one kilometre northwest of the DPB resource area. Assay determinations for TW22-119 are complete and show elevated gold and silver, along with its associated trace element signature of highly enriched antimony, lead, zinc and selenium, flanked by arsenic, potassium and aluminum as a halo around the quartz vein. This mineralization pattern is seen within the ore zones of the Tonopah West vein system. Figure 1 compares the Denver ore zone from TXC21-045 with TW22-119.Drillhole TW22-119 cut 4.5 metres of quartz vein material starting at 741 metres (2430 feet). Precious metal values reached 0.33 g/t gold and 24 g/t silver. From the same drill platform, TW22-120 was drilled southward with a 70-degree inclination targeting the same vein projection but shallower within the system. TW22-120 also encountered the vein over 3 metres at what may be a more favourable elevation within the system and assays are pending at this time. A cross section of the drilling shows the vein is located at the base of the Mizpah andesite which is the stratigraphic location of the Denver vein one kilometre to the southeast. In addition, drillholes TW21-073 and -074 are not deep enough to intersect the veinAndrew Pollard, Blackrock President & CEO, stated, \"As we await completion of our maiden resource estimate at Tonopah West, the latest assays from what is our largest step-out drill program to date have confirmed that this mineralized system goes well beyond the initial resource shell, far surpassing our initial targeting. By intercepting this mineralized vein structure far northwest of what was historically known to be an east-west vein corridor, confirms our geologic in...
