Blackrock Silver Receives Permit and Signs Drill Contract to off Set Bonanza-Grade Gold and Silver Discovery on the Silver Cloud Project

Vancouver, British Columbia--(Newsfile Corp. - May 23, 2023) - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is pleased to announce that it has received approval from the Nevada Bureau of Land Management and finalized a drill agreement with Tonatec Exploration LLC to commence its Phase-1 drill program at the Company's Silver Cloud property ("Silver Cloud"). Silver Cloud is located along the prolific, high-grade Northern Nevada Rift in north central Nevada adjacent to the Hollister mine and 15 kilometres south of the Midas mine.

In January 2023, the Company confirmed its original bonanza-grade discovery intercept at the Northwest Canyon target with metallic-screen assay which returned 1.52 metres grading 70 g/t gold and 600 g/t silver in core hole SBC22-020 (see news releases dated December 7, 2022, and January 17, 2023). A severe winter in northern Nevada precluded immediate follow up on this bonanza-grade intercept.

With ground conditions improving, access to Silver Cloud has now been restored and equipment can now be mobilized to the property. The Phase-1 drill program at Silver Cloud is anticipated to start in early June 2023.


Andrew Pollard, President and Chief Executive Officer of the Company commented: "This bonanza-grade gold and silver discovery at the Northwest Canyon target is a potential game-changer for Blackrock Silver and we've been chomping at the bit to get back up there with the drills ever since. After what was a very severe winter in Nevada, the snow has finally melted and access has been regained allowing us to mobilize our equipment and commence drilling in June, giving Blackrock the opportunity to finally walk this new exciting discovery forward with this fully-funded program."

Pollard continued, "Nestled along the Northern Nevada Rift, in between and on trend of two of Nevada's highest-grade historic gold mines, the Silver Cloud property holds tremendous potential in what may be the missing link of what is one big, high-grade system. In January 2023, we reported the highest-grade intercept we've had as a Company in making this new discovery, intersecting 1.52 meters grading 70 g/t gold and 600 g/t silver in core hole SBC22-020 in Northwest Canyon. Based on the historic drill data which has assays of 5.61 g/t gold over 12.2 meters, the Company believes the vein could extend up to 2 kilometers along a north-northwest orientation. This Phase-1 program will test an initial 500 metres of that strike potential."

The initial Phase-1 program will commence with 2,200 metres of drilling for approximately 500 metres of strike along the Northwest Canyon vein projection. The vein does not outcrop at the surface and is hosted within the porphyritic Silver Cloud Rhyolite volcanic unit. Based on data from previous historic drilling in the target area, including a drill intercept in SCP-15 of 12.2 metres grading 5.61 g/t gold, the Company believes the vein could have as many as 2 kilometres of strike length along a north-northwest orientation.

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 Silver Cloud are conducted and supervised by Mr. William Howald, Executive Chairman of Blackrock. Mr. William Howald, AIPG Certified Professional Geologist #11041, is a Qualified Person as defined under National Instrument 43-101. He has reviewed and approved the contents of this news release.
