Blackrock Silver Corp. announced drill results from the Company's ongoing step-out and in-fill drilling programs on its 100% controlled Tonopah West project located in West Central Nevada along the Walker Lane trend. These results demonstrate continued expansion of the key known mineralized structure on the project, the Denver vein system (also known as "Victor"), by an additional 600 metres to the Northwest, which has now grown to over 3 kilometres of drill-defined strike, and is projected to remain open to the west.

In addition, assays have encountered a substantial new zone of mineralization to the south, including highest-grade and shallowest intercept at the project to date. Drillholes TXC22-051 through -053 and TXC22-055 were completed in the Northwest Step Out target area. Drillhole TXC22-052 is 1,000 metres northwest of the DPB resource area and returned 4.6 metres grading 211 g/t AgEq beneath the Mizpah Andesite.

Data compilation in the Northwest Step Out target shows that drillhole TW22-118 encountered a mineralized structure and returned 170 g/t AgEq over 1.52 metres within the Mizpah Andesite; however, the drillhole terminated above the projected pay zone. TW22-118 is an additional 600 metres west of TXC22-052. Drillhole TW22-117 is 500 metres west of TW22-118.

The drillhole encountered the Mizpah Andesite, but was called at 762 metres; thus not testing the mineralized structure beneath the Mizpah. TXC22-055 was drilled to test the vein structure beneath the Mizpah andesite; however, the drillhole encountered a fault which off set the vein farther to the north. No significant assays were returned, but a better understanding of the cross structure was obtained from the drill information which will help to guide future drilling.

Blackrock's property boundary extends an additional 1,600 metres west of TW22-117. From the DPB resource area to the edge of the Company's property boundary, drilling suggests major potential along a 3,700-metre corridor immediately beneath the Mizpah Andesite. The vein system is in a similar stratigraphic position as the Denver vein drilled in the Victor and DPB resource areas.

The known strike of the Denver is 1,300 metres drilled in the Victor (500 m) and DPB (800m) resource areas. The Northwest Step shows an additional 3,700 metres of potential along the Denver vein system bringing the total to 5,000 metres of potential high-grade silver and gold on the Tonopah West project. Assay are pending from two core holes, and an additional five pre-collars are complete awaiting core tails.

Drilling in the New Discovery target was designed to follow up on Coeur Mining's 2018 drilling where drillhole TW18-004 encountered a 4.5 metre zone grading 4.933 g/t Au, 337 g/t Ag or 830 g/t AgEq. Core holes TXC22-056, -057, -058, -059 and TXC22-060 were completed in the target area. Core hole TXC22-057 returned one of the grade gold and silver intercepts from the project with over one ounce of gold (37.8 g/t Au) and 2.7 kilograms of silver reported over a 0.91 metre interval.

Drillholes TXC22-058, -59 and TXC22-060 all returned significant precious metal assays from the target. Expansion potential is evident, and additional drilling is highly warranted. Five core holes were completed in the Victor target to test down-dip extensions and footwall vein structures.

The drillholes encountered vein material and all assays are currently pending.
