Blackrock Silver Corp. (TSX.V: BRC) announced the successful completion of a small exploration drill program on its Silver Cloud project in Northern Nevada. The program included three core holes totaling 1,447 meters, two adjacent to the Silver Cloud mine target and one at Northwest Canyon.
The Silver Cloud gold mine had two holes intercepting a 30-meter-wide structural corridor oriented North-Northwest. Three core holes were drilled in 2019 as part of the Blackrock Silver program, including SBC19-001, which returned 3.928 g/t gold over a 0.8-m interval. The number of elevated gold intercepts from historic drilling and the Blackrock Silver results indicated that the North-Northwest structure was still plausible in the Silver Cloud mine. SBC22-019 and SBC22-021 were targeted to intersect a structural zone and tested 170 meters from the strike. SBC22-019 encountered pyrite-cemented breccia from 357 to 360 meters down the hole. Because the mineralization in this zone is similar to that in SBC19-001, the mineralization in this zone is similar.
The hole, SBC22-021, reached a maximum depth of 170 meters to the South-Southeast of SBC22-019. The drill penetrated oxidized breccia and fault gouge with intermittent quartz veining from 165 to 174 meters down the hole. The drill penetrated the North-Northwest structure, as indicated by the alteration. In Northwest Canyon, SBC22-020 was completed to a final depth of 464 meters. The North-Northwest structure that the Company observed in 2019 drilling (SBC19-002, 8.32 g/t gold over 1.52 meters) and Placer Dome’s 2002 drilling (12.2 meters grading 5.61 g/t gold), which was interpreted to project in the 350-meter step out to the South-Southeast, were targeted. From 307 to 309 meters down the
drill hole, SBC22-020 encountered quartz veins and stockwork containing pyrite and black sulfides. Results are pending at the moment.
