(TSXV: BRC) (the \"Company\" or \"Blackrock\") is pleased to report that the Company has commenced a fully funded 10,000 metre drill program on its Tonopah West project located in West Central Nevada along the Walker Lane gold and silver mineral belt. The project hosts a stope optimized inferred maiden resource estimate of 2.9 million tonnes at a block diluted grade of 208 grams per tonne (g/t) silver (Ag) and 2.5g/t gold (Au) for a total inferred mineral resource of 19,902,000 ounces Ag and 238,000 ounces Au, or 446 g/t silver equivalent (AgEq) for 42.6 million oz AgEq.[1] Silver equivalent grade is based on silver and gold prices of US$20/ounce and US$1750/ounce, respectively.The program consists of reverse circulation (RC) pre-collars with core tails through known mineralized zones. Blackrock has laid out 10,000 metres of drilling with 2,500 metres allocated for step-out and resource expansion drilling and a further 7,500 metres focused on drilling out high-grade structures internal to the resource area. Andrew Pollard, the Company's President and CEO, stated, \"Representing just 18 months of drilling data, baseline numbers from our maiden inferred resource estimate have established Tonopah West as one of the highest-grade undeveloped silver projects in the world[2], and we see significant opportunity for expansion, both within and external to the initial resource areas. With a refined model in hand, we have identified upside within the resource areas that should stand to benefit from additional drilling, targeting known, high-grade structures, in addition to infilling from successful step-out drillholes. Fully-financed for this program, drilling has commenced as we seek to grow our resource. We've seen remarkable return on investment via the drill bit thus far, with all-in discovery costs equating to US$0.62 per ounce AgEq. With less than two years of drilling at the project, it's evident we've only just scratched the surface in realizing its true potential.\"Expansion drilling to the northwest of the DPB resource shows upside with the intersection of the Denver vein confirmed in drillholes TW22-119 and 120.
