Vancouver - Blackrock Silver Corp. (TSXV: BRC) (the 'Company' or 'Blackrock') is pleased to report the results of its Maiden Resource Estimate ('MRE') at its 100% controlled Tonopah West project, located in the Walker Lane trend of Western Nevada.

The Tonopah West project is conveniently situated directly adjacent to the town of Tonopah in Western Nevada, with highway US 95 traversing the property, and the resource area is comprised entirely of patented mining claims.

The MRE was prepared in accordance with Canadian Institute of Mining, Metallurgy and Petroleum ('CIM') Definition Standards - For Mineral Resources and Mineral Reserves adopted May 10, 2014, and in accordance with National Instrument 43-101 'Standards of Disclosure for Mineral Projects' ('NI 43-101'). The effective date of the mineral resources estimated by RESPEC (formerly Mine Development Associates, 'RESPEC') is April 28, 2022.

Andrew Pollard, the Company's President and CEO, stated, 'Last prominent for the part it played during the era of the Pittman Act and the Peace Dollar, delivery of this maiden resource represents a historic milestone, as one of the great American silver camps has been re-awakened, at a time where silver serves as much more than just currency, but also as a crucial element required for the emerging global electrified economy. By stope optimizing our initial mineral inventory we've engaged the gold standard of detail, rigor and scrutiny for a project of this stage, which further de-risks the deposit while also bolstering the credibility in the baseline credentials of the Tonopah West project. Representing just eighteen months of drilling data, this maiden mineral resource estimate establishes Tonopah West as one of the highest-grade undeveloped silver deposits of size in the world[1], with substantial resource expansion potential remaining. We have seen an excellent return on investment via the drill bit, with all-in discovery costs of US$0.62 per ounce AgEq, and with drills at site turning at present we look forward to seeing this project continue to take shape. Congratulations to our Blackrock team, contractors, consultants and a heartfelt thanks to the community of Tonopah who have embraced us and for making this impressive high-grade precious metal discovery and maiden mineral resource estimate a reality.'

The MRE is presented as a stope optimized resource. Optimized stopes have a width of 1.5 metres, and a height and minimum length of 4 metres. The optimization resulted in stopes ranging from 4 metres to 100 metres in length. Block model metal values are based on US$20 per ounce of silver and US$1750 per ounce of gold with each block having a combined value per tonne based on silver and gold grade and their respective assigned recoveries.

The optimized resource is presented based on a split between cut-and-fill and longhole mining methods, which would be applied to exploit relatively shallow-dipping and steeply-dipping veins, respectively.

The MRE is based on a total surface drillhole database of 116 drillholes (65,870 metres) completed between June 16, 2020, and December 31, 2021. Total expenditures of $26.3-million USD have been made since acquiring the option on the project on April 1, 2020, to December 31, 2021, inclusive of all exploration, option payments and holdings costs, and G&A, which equates to a total discovery cost estimated to be US$0.62 per ounce of AgEq.

Drillholes were oriented between 90 to 50-degree inclinations from the surface with up to three drillholes at different inclinations completed from the same drill pad. Drillholes were spaced approximately every 50 to 100-metres along sections with 50-metre distance between sections in the DPB area. At Victor, drillholes were spaced between approximately 25 to 50 metres apart along sections with the sections 50 to 100-metres apart.

Forward-Looking Statements

This news release contains 'forward-looking statements' within the meaning of Canadian securities legislation. Such forward-looking statements concern the Company's strategic plans, completion of the maiden resource estimate on the Tonopah West project, timing and expectations for the Company's exploration and drilling programs, estimates of mineralization from drilling, geological information projected from sampling results and the potential quantities and grades of the target zones. Such forward-looking statements or information are based on a number of assumptions, which may prove to be incorrect. Assumptions have been made regarding, among other things: conditions in general economic and financial markets; accuracy of assay results; geological interpretations from drilling results, timing and amount of capital expenditures; performance of available laboratory and other related services; future operating costs and the historical basis for current estimates of potential quantities and grades of target zones. The actual results could differ materially from those anticipated in these forward-looking statements as a result of risk factors, including the ability of the Company to make payments related to the lease option to purchase the Tonopah West project; the timing and content of work programs; results of exploration activities and development of mineral properties; the interpretation and uncertainties of drilling results and other geological data; receipt, maintenance and security of permits and mineral property titles; environmental and other regulatory risks; project costs overruns or unanticipated costs and expenses; availability of funds; failure to delineate potential quantities and grades of the target zones based on historical data, and general market and industry conditions. Forward-looking statements are based on the expectations and opinions of the Company's management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statements were made.
