Blackrock Silver Corp. announced 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, totaling 1,447 metres (4,746 ft) in two target areas on the Silver Cloud project.

Two holes totaling 927 metres were completed adjacent to the Silver Cloud mine and one hole, 520 metres, was drilled at Northwest Canyon. At Northwest Canyon, SBC22-020 cut bonanza grades, 52.62 g/t gold (1.53 opt) and 606 g/t silver (17.68 opt) over 1.5 metres, representing a new high-grade vein discovery. The high-grade interval is associated with a banded and stockwork quartz veins containing black sulphides from 307.5 to 309.1 metres (1,009 to 1,014 ft) down the drillhole.

The 606 g/t silver is the highest-grade silver drill intercept on the Silver Cloud property to date. SBC22-020 was completed to 464 metres (1,523 ft). The core hole targeted the projection of the NNW structure encountered in the Company's 2019 drilling (SBC19-002: 8.32 g/t gold over 1.52m), and Placer Dome's 2002 drillhole (SCP-15: 5.61 g/t gold over 12.2m).

SBC22-020's collar location is a 366 metre step out, drillhole collar to drillhole collar, to the SSE along the interpreted structure; however, and the assay intercepts are separated by 425 metres. At the Silver Cloud mine, SBC22-019 and SBC22-021 targeted an interpreted structural zone and tested 170 metres of strike. SBC22-019 encountered a zone of pyrite-cemented breccia from 357 to 360 metres down the hole.

The zone was mineralized but below the 0.3 g/t gold cut off grade. An additional three zones of gold mineralization were encountered between 219 and 267 metres down the hole. These zones range from one to three metres in thickness and have gold values from 0.377 g/t to 0.578 g/t gold.

The intervals have been submitted for metallic-screen analysis. SBC22-021 was drilled 170 metres to the SSE of SBC22-019, and it encountered oxidized breccia and fault gouge with intermittent quartz veining from 165 to 174 metres (540 to 572 ft) down the hole. The alteration suggests the drillhole penetrated the intended NNW structure which is mineralized over a thick zone and returned assays yielding 20.6 metres returning 0.438 g/t gold.

The intervals have also been submitted for metallic-screen analysis. Additional work is being planned for Northwest Canyon to follow up on the new discovery. This area has limited drilling and shows potential for a large vein-hosted deposit similar to Midas.

At the Silver Cloud mine, more exploration is warranted to understand the thick zones of alteration with lower-grade gold mineralization. Quality Assurance/Quality Control: All sampling is conducted under the supervision of the Company's project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The core samples are hauled from the project site to a secure and fenced facility in Battle Mountain, Nevada, where they are loaded on to American Assay Laboratory's (AAL) flat-bed truck and delivered to AAL's facility in Sparks, Nevada.

A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company's instructions. The core and QA/QC samples are crushed and pulverized, then the pulverized material is digested and analyzed for Au using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split. Silver is determined using five-acid digestion and ICP analysis.

Over limits for gold and silver are determined using a gravimetric finish. Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or certified reference material approximately every 15th to 20th sample.

In addition, a random selection of pulps are sent to ALS Minerals in Reno, Nevada, for check assays. Blackrock's exploration activities at the Silver Cloud, Tonopah North and Tonopah West projects are conducted and supervised by Mr. William Howald, Executive Chairman of Blackrock.
