BLACKROCK SILVER DRILLS 4.7 METRES GRADING 714 G/T AGEQ (379 G/T AG AND 3.72 G/T AU) AND REPORTS MULTIPLE +1 KILOGRAM PER/TONNE AGEQ INTERCEPTS AT TONOPAH WEST

M&I CONVERSION PROGRAM EXPANDS AND CONFIRMS CONTINUITY OF HIGH-GRADE GOLD AND SILVER IN THE SHALLOWEST PORTION OF THE DEPOSIT

HIGHLIGHTS:

• TXC24-119 returned 4.69 metres of 714 grams per tonne (“g/t”) silver equivalent (“AgEq”) (379.0 g/t silver (“Ag”) and 3.72 g/t gold (“Au”)) from a depth of 370.4 metres, including 1.22 metres of 1,469 g/t AgEq (770.5 g/t Ag and 7.76 g/t Au).

• TXC24-117 yielded 2.01 metres of 1,783 g/t AgEq (1,141 g/t Ag and 7.13 g/t Au) from a depth of 261.2 metres, including 0.40 metres of 6,064.4 g/t AgEq (3,712 g/t Ag and 26.13 g/t Au).

• TXC24-102 intersected 0.98 metres of 1,048 g/t AgEq (628.0 g/t Ag and 4.67 g/t Au) from a depth of 152.9 metres, including 0.61 metres of 1,321 g/t AgEq (756.0 g/t Ag and 6.28 g/t Au).

• M&I Conversion Program: Assays for 5 completed drillholes are pending at this time, with a further 8 drillholes to be completed to finish off the program. An additional 6 reverse circulation (“RC”) drillholes have also been added to follow-up on high-grade mineralization encountered 200 metres to the east of the M&I Conversion Area.

• Resource Expansion Program: 9 drillholes testing broad continuity of high-grade gold & silver mineralization across a 1 kilometre vein corridor aiming to link the DPB resource area with the NW Stepout resource area have been completed with all assays pending at this time.

VANCOUVER, BRITISH COLUMBIA, CANADA (Newsfile Corp.– January 16, 2025) - Blackrock Silver Corp. (TSX-V:BRC) (OTC: BKRRF) (FSE: AHZ0) (“Blackrock” or the “Company”) is pleased to report the third tranche of assays from the M&I Conversion Program (as defined herein) on the Company’s 100% owned Tonopah West project (“Tonopah West”) located within the prolific Walker Lane trend in Esmeralda and Nye Counties adjacent to the town of Tonopah, Nevada, USA.

The Company's 2024 drill campaign on Tonopah West, which commenced in late July 2024, includes an in-fill drilling component consisting of approximately forty drillholes within the shallow southern portion of the DPB resource area with a goal to convert up to 1.5-million tonnes of material from inferred mineral resources to measured and indicated mineral resources (the “M&I Conversion Program”) and an exploration component that is targeting expansion potential across a one kilometre trend of vein corridor linking the DBP and the NW step out resource areas (the “Resource Expansion Program”).

The area in which the M&I Conversion Program is taking place (the “M&I Conversion Area”) represents the initial years of anticipated production based on the mine plan laid out in the Company’s Preliminary Economic Assessment on Tonopah West (the “PEA”) (see September 4, 2024 news release). The M&I Conversion Program has completed 32 of the planned 40 drillholes.? An additional 6 core holes from surface were added to follow up on high-grade intercepts encountered in the course of the M&I Conversion Program.? To the end of December 2024, a total of 10,055 metres (32,989 feet) have been completed. The Company has received assays for 28 of the 32 drillholes completed, with assays for five drillholes pending. Eight pre-collars and core tails will be completed in early 2025 to complete the M&I Conversion Program.? Table 1 shows the third installment of drillhole assays received to date at a 150 g/t AgEq cut-off grade.

Andrew Pollard, the Company’s President and CEO, stated, “Assay results from our ongoing M&I Conversion Program continue to tie together shallow high-grade gold & silver mineralization both within and up-dip from the existing resource area that is projected to represent the initial years of production at Tonopah West. A new very shallow zone of interest has emerged east of the M&I Conversion Area, and additional drilling is being deployed to test roughly 200 metres of new strike potential along what is thought to be the Merten vein.? In addition, we expect to have our first tranche of assays from our separate Resource Expansion Program over the coming weeks, where 1 kilometre of vein corridor is being drill tested with an aim of adjoining high-grade mineralization between our DPB and Northwest Step Out deposits. Drilling remains ongoing at site, and with a substantial backlog of assays pending at the lab from both our M&I Conversion Program and Resource Expansion Program, the Company is poised for an active start to 2025.”
