Blackrock Completes Synthesis of Silver Cloud Data and Has Identified 10 High-Priority Drill Targets
Vancouver, British Columbia--(Newsfile Corp. - June 22, 2022) - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") is pleased to report that the Company commissioned Goldspot Discoveries Corp. ("Goldspot") to complete a compilation and apply their proprietary machine learning program on the Silver Cloud project located along the high-grade Northern Nevada Rift in north-central Nevada.
The Goldspot synthesis utilized regional- and project-scale geophysical, lithologic and geochemical data sets to unmask and expose the fundamental gold-bearing structures that may contain high-grade gold and silver mineralization - similar to the nearby deposits of Midas and Hollister. The synthesis combined the compiled data set and machine learning technology to produce a set of targets that were then reviewed and adjusted based on the Company's project geologist's ideas and suggestions. The collaborative effort produced 10 high quality and high-priority drill targets.
Blackrock Silver President & CEO, Andrew Pollard, commented, "With an impressive track record of high-grade discoveries on established gold belts already to their credit, we felt our Silver Cloud project, adjacent to two of the highest-grade gold mines in Nevada, would make for the perfect collaboration with Goldspot to apply their machine learning algorithm, tasked with crunching an immense amount of regional and project level data in an effort to generate new targets. A significant amount of new regional geophysical data was unearthed and licensed in the process, the result of which has led to a new understanding of the project. We have identified 10 high-priority drill targets and permitting is underway that will allow us to test these concepts in the fall."

SCX-001 and -002 are testing a 30m wide structural zone with gold up to 7.7 g/t. High-grade gold was returned from core holes SBC19-001 (3.84 g/t Au), SCT-8 (7.68 g/t Au), SCT-9 (4.57 g/t Au) and SCT-7 (2.58 g/t Au). The gold mineralized structure is dipping steeply to the east. SCX-001 and -002 are designed to test this north-northwest trending mineralized zone.
After a review of previous drilling in the Northwest Canyon area, it appears the high-grade mineralization is oriented in a different direction than previously thought. SBC19-002 intersected coarse gold, up to 8.32 g/t Au over 1.5 metres in a series of quartz veins stringers. SCP-15 intersected 12.2 metres of 5.61 g/t Au. SCX-003 will attempt to tie the mineralization in SBC19-002 and the older PDX drillhole. Modelling now suggests mineralization is along a NNW structure dipping east.
In the centre of the Silver Cloud property is a demarcation between felsic volcanic rocks on the west side of the property and intermediate to mafic volcanic rocks on the east side of the project. SCX-004 and -005 are testing this NW oriented geologic boundary. At site SCX-005 there is elevated mercury in rock and soil samples following the geologic/structural break.
SCX-006 is in Honey Hill and will test an E-W structural corridor interpreted from the project gravity data. The drillhole will intersect the underlying unconformity between the younger volcanics and the Paleozoic basement.
SCX-007 and -008 are testing coincident gravity and geochemical anomalies in the Quiver target. SCX-007 will also follow up on gold mineralization intersected in SBR20-017 (15.2 m grading 0.222 g/t Au). It appears that SBR20-017 may have paralleled an important N-S structure. SCX-007 will cut across the structure.
SCX-009 is testing a newly identified northeast oriented outcropping vein that dips to the southeast. Geologic review of the Quiver target area shows a northeast oriented vein that has never been drill tested. The vein contains elevated mercury in outcrop.
Immediately west of the Silver Cloud mercury mine, Goldspot identified a parallel north-northwest trending structure. The position is based on geochemistry and gravity data. SCX-010 will test this parallel structure.
Permits have been summited to the BLM, and a core and RC drill have been scheduled for a fall drill program which will consist of 4,400 metres across 10 drillholes (5 RC, 5 core). Permits are anticipated before the end of summer.
Blackrock's exploration activities at the Silver Cloud project are conducted and supervised by Mr. William Howald, Executive Chairman of Blackrock.

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.
