Blackrock Silver Announces Silver Cloud Results; Tonopah West Resource Update Timeline
Drilling Update NevadaFollowTSX.V: BRCWebsite
Mr. Andrew Pollard reports:

Vancouver, British Columbia--(Newsfile Corp. - September 26, 2023) - Blackrock Silver Corp. (TSXV: BRC) (the "Company" or "Blackrock") reports assay results for its 100% controlled Silver Cloud project ("Silver Cloud") located in north-central Nevada along the Northern Nevada Rift trend.


Intercepts up to 2.24 g/t gold were encountered in banded epithermal quartz veins;

Multiple banded epithermal veins were encountered with drilling confirming the orientation and dip of the epithermal vein structure with a westerly dip; and

The mineral resource update for the Company's Tonopah West project located within the Walker Lane trend in west central Nevada remains on track for completion in October 2023.

The Company completed a core program centered on the Northwest Canyon epithermal vein intercept that encountered 1.52 metres grading 70 g/t gold and 600 g/t silver in its 2022 drill program (see January 17, 2023 news release). The 2023 drill program consisted of five core holes totalling 1,827 metres.

The drilling showed the epithermal vein system has a strike with azimuth of 340 degrees and a dip of 60 degrees to the west. The vein structure shows a much shallower dip than originally thought and drillholes were not in the optimum location for the shallow westerly dip. Several permitted sites were not drilled as a result.

Gold and minor silver mineralization was encountered in drillholes SBC23-025 and -026. These holes were 25-metre and 100-metre step-outs located north from the original high grade bonanza intercept. While the strike and dip of the vein is better understood, the orientation of the high-grade gold and silver is not. Table 1 shows assay results above 0.2 g/t gold.

Andrew Pollard, President and Chief Executive Officer of the Company, stated, "As we await completion of our updated mineral resource estimate for our flagship Tonopah West project, which remains on track for October, the results from our targeted follow-up campaign at Silver Cloud continue to refine our understanding of the geologic controls of the mineralized system at the Northwest Canyon target. Though we have a good understanding of the strike and orientation of the structure, we have not yet been able to replicate the grades seen in SBC-22-20. A review of the down-hole geochemical data is underway to better pinpoint where the high-grade system is localize."
