Blackrock Silver Corp.  (TSXV: BRC) (OTCQX: BKRRF) (FSE: AHZ0) (“Blackrock” or the “Company“) is pleased to announce the second set of assay results 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 is completing an in-fill drilling campaign (the “M&I Conversion Program“) consisting of forty drillholes within the shallow southern portion of its’ DPB resource area with an aim to convert up to 1.5-million tonnes of material to the measured and indicated mineral resource category, with the drillhole pattern being implemented on 25-metre centers. This area represents the initial years of proposed production based on the mine plan laid out in the Company’s recently announced preliminary economic assessment for Tonopah West (see news release dated September 4, 2024).

The M&I Conversion Program commenced in late July 2024 pursuant to which the Company has completed 32 of the planned 40 drillholes. An additional 6 core holes from surface have been added to the M&I Conversion Program to follow up on high-grade intercepts encountered in TXC24-087. Pursuant to the M&I Conversion Program, a total of 10,283 metres (33,737 ft) of drilling have been completed to date and the Company has received assays for 27 of the 34 drill holes completed (see Table 1 below for all assay results received to date from this program).

“Multiple high-grade zones are emerging on our Merten vein system as additional results from our ongoing M&I Conversion Program continue to increase confidence in our model. Near surface mineralization has been tracked from 137 metres down to 367 metres downhole, with each distinct zone delivering intercepts beyond 2,000 g/t AgEq while establishing exceptional continuity along the vein. Additional high-grade mineralization has been identified up-dip which appears to connect to a once thought isolated zone to the east (TW21-076: 4.6 metres grading 510 g/t AgEq). The M&I Conversion Program is targeting up to 1.5 million tonnes of material for potential conversion. Additional drillholes are being added to this fully-funded program to follow up on TW21-076. Drills are poised to remain at site through the end of the year and into Q1 2025, and with many completed drillholes pending assays, we expect to finish 2024 on a strong note.”

Andrew Pollard, the Company’s President and CEO, stated

The M&I Conversion Program establishes continuity of the high-grade zone within the Merten vein. Two additional zones are coming together and showing that Merten has potentially three high-grade silver and gold zones based on the drill results received to date. Figure 1 below illustrates a long section along the Merten vein illustrating grade times thickness, demonstrating the high-grade silver equivalent zones have up to 200 metres of length across the Merten vein structure.

TXC24-077, -078, 079, -082, -088, -089, -093, -096, -097 and TXC24-099 returned silver and silver equivalent assay intervals albeit below the 150 g/t AgEq cut-off grade. In these core holes: (i) gold values range from 1.45 to 0.185 g/t Au; (ii) silver values range from 91.9 to 3.4 g/t Ag; and (ii) silver-equivalent values range from 222.4 to 32.5 g/t AgEq, with drillhole intervals between 4.7 and 0.6 metres. Although the assays are below the cut-off grade, the low-grade intercepts confirm the modelled vein geometries and thicknesses along the Fraction caldera margin, and help to define the high-grade chutes within the Merten vein.

An additional high-grade silver equivalent zone has emerged to the east of the M&I Conversion Program drilling area, and the Company’s plans to drill additional drillholes in 2025 to follow up on this isolated intercept along the Merten vein.

The drilling conducted pursuant to the M&I Conversion Program utilized a reverse circulation (RC) to drill to complete pre-collar drillholes to various depths and then core tails to drill through the modelled target zones in DBP area.

TXC24-079, -089, -090 and 105 encountered voids in the drilling. The voids are the result of fault fractures and potentially old workings. The cavities were between 2 to 6 metres in width. The larger cavity caused TXC24-090 to be terminated prematurely.

The M&I Conversion Program is completing 2 to 3 core tails per week with lab turn around at roughly 6 to 8 weeks. With 34 drillholes completed to date, there are seven drillholes with assays pending. RC pre-collars have been completed for eleven holes that are awaiting core tails. Additional assay results from the M&I Conversion Program will be forthcoming over the next several months.

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 RC and core samples are hauled from the project site to a secure and fenced facility in Tonopah, 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 RC samples are lined out at the lab and logged in to AAL’s system. The core samples are cut using core saws and personnel at AAL’s facility in Sparks, Nevada according to the Company’s instructions delivered with each core hole.

All samples are dried, crushed to 85% passing 10 mesh (2mm) and a 250-gram sub-sample split is collected and pulverized to 200 mesh (74 micron) in a ring and puck pulverizer. Then the pulverized material is digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split (FA-PB30-ICP). Silver is determined using five-acid digestion and ICP analysis (ICP-5AM48). Over limits for gold and silver are determined using a gravimetric finish (GRAVAU30 and GRAVAG30). 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 a certified reference material approximately every 15th to 20th sample.
