December 07, 2022, ? Vancouver, British Columbia. Blackrock Silver Corp. (the “Company” or “Blackrock”) is pleased to announce the results of its recently completed diamond exploration drill program on its 100% controlled Silver Cloud project situated 20 kilometres south of the Midas mine and 3 kilometres west of Hollister mine, along the prolific Northern Nevada Rift in north-central Nevada.

The Company completed three diamond core holes, SBC22-019, -020, AND -021, totalling 1,447 metres (4,746 ft) in two target areas on the Silver Cloud project. Two holes totalling 927 metres were completed adjacent to the Silver Cloud mine and one hole, 520 metres, was drilled at Northwest Canyon.

Highlights:
Bonanza grades were returned from SBC22-020, which intersected 52.62 g/t gold (1.53 opt) and 606 g/t silver (17.68 opt) over 1.5 metres in the Northwest Canyon area, representing a new high-grade vein discovery now known as Zeus;
SBC22-020 was directed at a conceptually projected structure based on results received from Blackrock’s SBC19-002 (8.32 g/t gold over 1.52m) and Placer Dome’s SCP-15 (5.61 g/t gold over 12.2m). These assay intercepts represent a high-grade drill defined structure separated by 425 metres;
The bonanza grades are associated with a banded quartz vein which contains black sulphides, and the 606 g/t silver is the highest-grade silver intercept on the Silver Cloud property to date;
SBC22- -021 drilled at Silver Cloud Mine returned significant thickness of low-grade gold returning 20.6 metres grading 0.458 g/t gold; and
Coarse gold is known to occur on the property, and all significant gold intervals will be re-submitted to the assay laboratory for metallic-screen analysis.
Andrew Pollard, Blackrock President and CEO, commented, “Silver Cloud was the project Blackrock was built around in its current form beginning three years ago, and though our Tonopah West property has now become a globally significant silver discovery, it’s Silver Cloud that has returned our highest-grade gold intercept as a Company to date, in the process, establishing a new bona fide high-grade discovery on one of the most prolific gold belts in Nevada. Our understanding of the rich ore deposits along the Northern Nevada Rift were key to making the Zeus discovery. The Midas mine, located 20 kilometres to the north, which started with a similar intercept, ultimately lead to the discovery of the Colorado Grande
and Gold Crown veins which were 0.3 to 6 metres wide, yet managed to form the basis for one of Nevada’s most iconic historic gold mines. Making a blind discovery of this magnitude on such a limited round of drilling is a testament to the calibre of our geologic team. The discovery of Zeus may have just parted the Silver Clouds once and for all, with indications that the system has plenty of room to grow from here.”
