Blackrock Silver Corp. (BKRRF) has announced significant results from its RC Scout Drilling Program at the Tonopah West project in Nevada. The program, completed between December 2024 and January 2025, consisted of ten exploration drillholes totaling 3,857 metres.

Key highlights include:

  • Discovery of a new high-grade zone extending up to 1,200 metres east of the existing DPB resource
  • Notable intercepts include TW25-128 with 9.6 g/t gold and 1,198 g/t silver over 1.52-metres
  • TW25-133 returned multiple mineralization zones, including 10.46 g/t gold and 10.6 g/t silver over 4.57-metres

The program successfully extended the Merten vein system by 540 metres along strike to the east. The new mineralized zone is not included in the 2024 resource and may significantly impact the upcoming DPB South resource update scheduled for Q3 2025. Additional drilling has been deployed with three core holes pending results.

Scout Drilling Confirms the Extension of the High-Grade Merten Vein Creating Potential to Expand the DPB Resource up to 1,200 Metres to the East

Vancouver, British Columbia--(Newsfile Corp. - March 31, 2025) - Blackrock Silver Corp. (TSXV: BRC) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") is pleased to announce the results from the reverse circulation ("RC") Scout Drilling Program completed on the southeastern side of the DPB M&I Conversion area on its 100% owned Tonopah West project located in Nye and Esmeralda Counties, Nevada, United States.

Starting in late December 2024 and finishing in late January 2025, the Company completed ten exploration RC drillholes in the eastern portion of the DPB area and the adjacent Ohio target to test for gold and silver along a structural zone and beneath a felsic sill. A total of 3,857 metres (12,655 ft) was drilled. The program was very successful with silver and gold being returned from all targets.

SCOUT PROGRAM HIGHLIGHTS:

  • Assays from our reverse circulation scout drill program have returned significant gold & silver values in 7 drillholes that have successfully expanded the footprint of mineralization up to 1,200 metres to the east of the existing DPB resource toward the historic Ohio mine;

  • These intercepts cover a new zone of mineralization not included in the 2024 resource that may impact the upcoming DPB South resource update (Q3, 2025);

  • TW25-128 which returned 9.6 grams per tonne (g/t) gold and 1,198 g/t silver over 1.52-metres (2,063 g/t silver equivalent (AgEq)) from 292 metres in the Ohio area;

  • TW25-133 returned multiple thick zones of mineralization including 10.46 g/t gold and 10.6 g/t silver over 4.57-metres (952 g/t AgEq) including 1.52 metres grading 21.45 g/t gold and 15.7 g/t silver (1,948 g/t AgEq) from 309 metres and 3.05 metres grading 270 g/t AgEq (129 g/t silver and 1.57 g/t gold) from 280 metres;

  • TW25-130 cut 1.52 metres of 587 g/t AgEq (3.3 g/t gold and 290 g/t silver) from 189 metres

  • Assays from multiple drillholes have extended the Merten vein system by 540 metres along strike to the east of the main DPB South resource. With the inclusion of discovery hole TW25-128, targeting an area historic miners referred to as the Ohio vein, the mineralized trend could extend up to 1,200-metres in length;

  • Additional drilling has been deployed to this area and assays for three core holes, TXC25-133, -134 and -135 are pending.

Andrew Pollard, Blackrock's President and CEO, stated, "Results from our RC Scout drilling program confirm the discovery of a new high-grade gold and silver structural zone extending 1.2 kilometres (km) east from our existing resource shell. Historic miners referred to this eastern target area as the Ohio Vein, a substantial producer in the early 1900's, but until now, its mineralization had remained elusive. With every drillhole in this program returning elevated grades across the trend, the scale of the project has increased dramatically, with the results suggesting significant new high-grade tonnage potential. Coupled with our recently released expansion results (see February 24, 2025 news release), where we successfully stepped out 500 metres to the northwest, we have increased the footprint of high-grade mineralization along the vein corridor by over 65% this year, adding an additional 1.7km of drill-defined strike. We have already deployed additional drilling to this new zone, with assays for three core drillholes pending."

TW25-133 returned significant silver and gold with values starting at 309-metres grading 10.46 g/t gold and 10.6 g/.t silver over 4.57 metres (952 g/t AgEq). This mineralization extends the Merten vein 540 metres to the east-southeast of the main DPB South resource. With the inclusion of TW25-128 which returned 9.6 g/t gold and 1198 g/t silver over 1.5-metres (2,063 g/t AgEq), the zone could be up to 1,200-metres in cohesive strike. Table 1 summarizes the assay results (150 g/t AgEq cutoff).

Drilling suggests the Merten vein extends eastward and is arched and dips southward. This orientation suggests multiple ring structures associated with the Fraction caldera. An inner structure hosting the Victor and DPB North (Denver and Paymaster) resources, and an outer, more southern, ring structure hosting DPB South (Merten and Bermuda) and the NW Stepout resources. The arching geometry of the Merten vein is similar to that described from the historic Ohio vein which was 15 metres thick when mined in the early 1900s1. Given the geometry and location, the Merten is potentially the extension of the Ohio vein.

The mineralized zone traced by these assay results is new and not included in the 2024 resource. These results may have a substantive impact on the planned DPB South resource update scheduled for Q3 2025.

Drillholes TW24-124, TW25-126 and TW25-129 did not return assay values above 150 g/t AgEq. TW24-124 and TW25-126 were in the DPB area while TW25-129 was collared in the Ohio area. These drillholes had mineralization which ranged between 49 to 60 g/t AgEq. Assays for three core holes, TXC25-133, -134 and -135 are pending.

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 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 into AAL's system. The 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.
