December 20th, 2021, ? Vancouver, British Columbia. Blackrock Silver Corp. (the “Company”) is pleased to announce additional high-grade silver and gold intercepts from its DPB in-fill core and RC step-out drilling programs on the 100% controlled Tonopah West project, located in the Walker Lane trend of Western Nevada.
Step-out drilling has successfully expanded the footprint of mineralization beyond the 800 metre by 800 metre area that will form the basis for the upcoming maiden DPB resource. In-fill results continue to demonstrate continuity of high-grade mineralization and enhance the Company’s understanding of the structural orientation of this growing, multi-vein system. The Tonopah West project is conveniently situated directly adjacent to the town of Tonopah, with Interstate 95 traversing the property, and the DPB resource area is entirely on patented ground. The Company is working towards delivery of a maiden resource estimate during Q1, 2022.
HIGHLIGHTS:
TXC21-020 hit significant mineralization in the Merten vein system, returning 48 g/t gold (Au) and 258 g/t (Ag) over 3.5 metres (500 g/t AgEq) including a 1.1 metre zone grading 4.37 g/t Au and 427 g/t Ag (864 g/t AgEq). (AgEq_= Ag_g/t + Au_g/t*100). The gold and silver values appear to thicken and increase in grade along this intersection zone;
Drillhole TW21-099 demonstrates that the Merten vein has an additional 275 metres of up dip potential, cutting 2.28 g/t Au and 0.48 g/t Ag or 232 g/t AgEq over 1.5 metres and a second intercept of 1.16 g/t Au and 127 g/t Ag or 243 g/t AgEq over 3 metres. Using a lower cut off of 31 g/t AgEq gives a result of 13.7 metres grading 0.53 g/t Au and 53.2 g/t Ag or 106 g/t AgEq starting at 215 metres down the drillhole. Additional drilling is required, but the near-surface projection of the vein system may represent a new, near-surface target to pursue. The Merten vein system is the largest mineralized feature identified to date. The vein and its accompanying hangingwall and footwall splays have 5 kilometres of strike and over 1,200 metresof drill-tested dip potential;
TW21-090 expanded the Bermuda vein system by 100 metres, cutting 2.15 g/t Au and 67 g/t Ag over 1.5 metres (282 g/t AgEq) east of the DPB resource area;
In-fill program has delivered an additional 20 significant intercepts ranging from above 200 g/t AgEq cutoff up to 864 g/t AgEq (4.37 g/t Au and 427 g/t Ag); and
Assays are pending for 13 core holes (TXC21-037 to TXC21-049) and 12 RC drillholes (TW21-105 to TW21-116). The 2021 program is complete.
Andrew Pollard, the Company’s President and CEO, stated, “With our maiden resource estimate on track for Q1, 2022, in-fill results continue to demonstrate excellent continuity of this prolific silver-gold system, while our step-out program has expanded the footprint of known mineralization across multiple veins, highlighting significant near-surface potential in the process. The Merten Vein system, already by far the largest mineralized structure we’ve identified on the property, continues to expand with drilling. We’ve completed over 80,000 metres of drilling at the project thisyear, and 110,000 metres since inception in June of 2020, and we believe that we’ve barely scratched the surface in understanding its’ true potential. We’re well-financed and gearing up to hit the ground sprinting in the New Year in our efforts to define just how large this system may truly be.”
