Discovery Of New Vein At The Tonopah West Project

VANCOUVER - Blackrock Silver Corp. reported more high-grade gold and silver drill intercepts from its core and RC drilling program on the 100% controlled Tonopah West project located in the Walker Lane trend of Western Nevada. These results support the high-grade nature of the DPB and Victor targets; validate the Company's understanding of the structural orientation of the vein structures at DPB; and highlight the considerable silver and gold potential within these two growing target areas.

The step-out drilling to the west intersected high-grade silver and gold in TW21-068 with 16.0 g/t Au and 1,722 g/t Ag or 3,322 g/t AgEq within a broader zone of 4.5 meters grading 6.56 g/t Au and 743 Ag or 1,399 g/t AgEq on the strike extension of the Merton vein (AgEq=silver: gold ratio 100:1). The Merton vein now has 1.5 kilometers of mineralized strike with high-grade shoots showing up to 400 meters of vertical elevation. At the Victor target TW21-077 cut two zones grading 3.075 g/t Au and 310 g/t Ag or 617.5 g/t AgEq over 3 meters and 7.6 meters grading 2.139 g/t Au and 230 g/t Ag or 444 g/t AgEq including 1.5 meters grading 4.89 g/t Au and 512 g/t Ag or 1,001 AgEq. The silver-gold results bolster the Victor target and confirm the thick, high grade nature of the Victor vein. The Victor/Murray veins system has 500 meters of strike from the eastern project boundary to the Pittsburgh-Monarch fault system. The TW21-093C represents a step out along the Victor/Murray vein system. This drillhole cut 1.93 g/t Au and 203 g/t Ag or 400 g/t AgEq over 0.8 meters and extends the mineral system to the east. Drilling has discovered a new mineralized vein on the footwall side of the Pittsburgh-Monarch fault system with 2.2 meters grading 1.53 g/t Au and 141 g/t Ag or 294 g/t AgEq in TW21-092C and 3.9 meters grading 0.48 g/t Au and 67 g/t Ag or 115 g/t AgEq in TW21-033C. This new vein may represent the faulted offset portion of the Victor/Murray vein system. The first hole of the core in-fill drilling program on the Denver vein returned 3.1 meters yielding 1.3 g/t Au and 136 g/t Ag or 265 g/t AgEq in TXC21-001.

"In under one year, we have completed 53,000 meters of drilling and have successfully identified ten high-grade veins ranging in size from 400 meters up to 1.5 kilometers in strike, almost all of which remain open for expansion. This silver-gold project continues to deliver world class results as drilling advances, expanding the footprint of known mineralization, both along strike and at depth. Not only is our geologic model predictive at this point, our understanding of the controls of the high-grade distribution are becoming readily apparent," said, Andrew Pollard, President & CEO. "On the Merton vein, we have now established 1.5 kilometers of strike, in addition to having identified two distinct high-grade zones, highlighting a vertical mineralized extent of over 400 meters. Merton represents just one of the six different veins that make up our DPB target, all of which shall form the basis for our maiden resource estimate we plan to deliver by the end of the year. Drilling continues to expand our Victor target, with 500 meters of mineralized strike now established to the eastern extent of our property, and the first drillholes testing the western extension of the system on the footwall side of the Pittsburgh-Monarch fault have returned impressive grades that highlight the potential for an additional 600 meters of strike within a new vein. With more assays pending, four rigs in operation, and 17,000 meters of drilling remaining for our 2021 program, investors have a lot to look forward to in the near term."
