Blackrock Silver Corp. announce 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. Initial results successfully expand the Denver vein one kilometre beyond the boundary of the April 2022 maiden resource estimate, effectively doubling the footprint of mineralization.

Step Out Program Blackrock kicked off the 2022 exploration program with highly aggressive step-out drilling that was guided based on the Company's learnings from drilling out the Tonopah West resource (2.9Mtonnes at a block-diluted grade of 446 g/t AgEq or 42.6 Mozs of AgEq; "Technical Report and Estimate of Mineral Resources for the Tonopah West Silver-Gold Project, Nye and Esmeralda Counties, Nevada, USA" effective April 28, 2022, and dated June 16, 2022). Core hole TXC22-052 intersected 4.6 metres of the Denver vein grading 0.63 g/t gold and 148 g/t Ag or 211 g/t AgEq including a 0.7metre zone grading 1.89 g/t gold and 513 g/t silver or 702 g/t AgEq. TXC22-052 is located one kilometre northwest of the northwest corner of the DPB resource area.

TXC22-052 is significant as it effectively doubles the strike potential of the Tonopah West vein system. The Denver vein, or its equivalent, has now been encountered at high grades over 2,500 metres of strike. The Company's April 2022 maiden resource estimate incorporated drilling that covered1,300 metres of strike.

Core hole TXC22-052 demonstrates that substantial upside potential exists along 1,200 metres of additional strike. TXC22-051 was drilled 650 metres north-northwest of TXC22-052. The drillhole encountered the Denver vein geology and intersected elevated gold and silver along with high values of copper (up to 541 ppm), lead (up to 532 ppm) and zinc (up to 10,000 ppm) within the projected Denver vein zone starting at 1,112 metres down the hole.

Immediately beneath the Denver vein, the drillhole interested a granodiorite intrusive. The granodiorite could be important and may have a genetic and spatial link to the source of the Tonopah district gold and silver mineralization as well as provide understanding on the structural architecture observed in the district. TXC22-053 was drilled 330 metres north of TXC22-052.

The core hole targeted the down dip projection of the Denver vein. The core encountered elevated gold and silver along with anomalous copper (808 ppm), lead (up to 395 ppm) and zinc (up to 688 ppm) over 5.52 metres interval at the projected depth (764 metres) of the Denver vein. TXC22-054 was a 200 metre step out to the west of the DPB resource area and was drilled to understand the structural orientations where the Denver vein rotates from east-west to northwest.

TXC22-054 returned 0.3 metres grading 1.81 g/t gold and 127 g/t silver or 308 g/t AgEq. In-Fill Program In-fill drilling started within the New Discovery area with core hole TXC22-056 through TXC22-060 having been completed and samples sent to the assay lab (assays pending). The drillholes are exploring for gold and silver mineralization that is within 200 metres of the surface.

To date, drilling has encountered mineralization in the form of stockwork quartz veins and breccia zones associated with the Oddie Rhyolite intrusive. XRF investigation of the core shows elevated values for gold and silver indicating near surface potential for the mineralized system. Assays are pending at this time.

Core TXC22-061 was completed in DPB. In-fill drilling is currently in process within the Victor area. On May 12, 2022, the Company announced commencement of a fully funded drilling program.

A total of 3,625 metres of core, 3,298 metres in pre-collar holes and 396 metres of RC drilling have been completed. The announced program has been expanded and is approximately 50% complete.
