Blackrock Silver Steps Out and Hits Multiple +1 kg/t AgEq Intercepts in First Assays from Resource Expansion Program at Tonopah West

Multiple High-Grade Veins Encountered in Corridor Bridging the Southern Portion of a 1-kilometre Gap Between the DPB and the NW Step Out Area with Additional Resource Expansion Program Drilling Planned

RESOURCE EXPANSION PROGRAM HIGHLIGHTS:

  • TXC25-123 returned assays up to 23.47 g/t Au and 2,223 g/t Ag for 4,335 g/t AgEq over 0.31 metres within a 3.05 metre zone grading 225 g/t Ag and 2.41 g/t Au for 442 g/t AgEq;

  • TXC24-113 yielded 7.14 g/t Au and 614 g/t Ag for 1,257 g/t AgEq over 0.31 metres, and 1.68 metres of 364 g/t Ag and 0.03 g/t Au for 367 g/t AgEq;

  • TXC25-124 returned 8.06 metres grading 1.23 g/t Au and 122 g/t Ag for 233 g/t AgEq, including 0.76 metres of 779 g/t Ag and 7.85 g/t Au for 1,486 g/t AgEq;

  • Multiple high-grade vein intercepts in drillholes TXC24-113, TXC25-123 and TXC25-124 returning multi-kilogram AgEq assays;

  • The NW Step Out target shows potential to add an additional 30 to 50% of new resource to Tonopah West, allowing for the capture and inclusion of the NW resource (1.0M tonnes containing an inferred 6.4M ozs Ag and 63k ozs Au or 12.1M ozs AgEq)1 into a future updated preliminary economic assessment on Tonopah West; and

  • Seven additional core holes are planned to reduce the spacing to 50-metre drill centres along a 450 metre portion of the trend.

Vancouver, British Columbia--(Newsfile Corp. - February 24, 2025) - Blackrock Silver Corp. (TSXV: BRC) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") announces the first set of results from its exploration drill program (the "Resource Expansion Program") that is targeting expansion potential across a one kilometre trend of vein corridor linking the Denver-Paymaster ("DP") and Bermuda -Merten ("Bermuda) vein groups (collectively "DPB") and the Northwest ("NW") Step Out resource areas on its 100% owned Tonopah West project ("Tonopah West") located in Nye and Esmeralda Counties, Nevada, United States.

The first assays from the Resource Expansion Program targeting the extension of the Tonopah West vein system returned results that confirm the Company's geologic model and will be followed up on over the coming months in an expanded program. The initial Resource Expansion Program consisted of nine core holes with reverse circulation (RC) pre-collars and two core holes drilled from the surface. A total of 6,548 metres (21,484 feet) of drilling was completed.

The assay results show the extension of the silver and gold system continues to the northwest from the DPB resource area across the 1-kilometre vein corridor with each drillhole intersecting multiple mineralized quartz veins. A follow-up drill program is being planned that will reduce the drill spacing for over 450-metres of strike to 50 to 75-metre centers along the silver-gold trend that will be included in a future updated resource estimate. The NW Step Out zone is also open to the northwest and down dip, and connection with the DPB resource looks promising.

The mineralized quartz veins returned significant gold and silver values with gold (Au) up to 23.467 grams per tonne (g/t) Au and silver (Ag) values at 2,223 g/t Ag. In addition, drill thickness shows significant potential with vein intercepts exceeding 8 metres in TXC25-124. The NW Step Out target shows potential to add an additional 30 to 50% of new resource Tonopah West, connecting the zone to DPB, allowing for the capture and inclusion of the existing NW resource (1.0 million (M) tonnes containing an inferred 6.4 M ounces (ozs) Ag and 63k ozs Au or 12.1M ozs silver equivalent (AgEq))1 into a future updated preliminary economic assessment on Tonopah West.

Andrew Pollard, the Company's President and Chief Executive Officer stated: "Initial assay results from our Resource Expansion Program have validated our geologic model, confirming multiple +1k g/t AgEq intercepts on the extension of the system across a host of veins over a 500-metre span of our one-kilometre gap. These results strengthen our confidence in adding both significant ounces and mine life at Tonopah West. Drilling has successfully connected high-grade mineralization within the southern portion of a one-kilometer gap within the vein corridor, linking the DPB resource area and mine plan to the 12-million-ounce AgEq NW Step Out deposit-excluded from our 2024 preliminary economic assessment. Initial results have successfully traced mineralized structures along a 500-metre extension of this zone, suggesting the potential to increase our existing mineral inventory by 30% to 50% and integrate the orphaned NW Step Out deposit. With our model becoming more robust, we are increasing expansion drilling with the goal of fully integrating the one-kilometre trend into our next preliminary economic assessment on Tonopah West, with an updated mineral resource estimate on Tonopah West planned in both Q3, 2025, in addition to a further updated mineral resource estimate and preliminary economic assessment on Tonopah West scheduled for completion in Q2 2026."

Drillholes TXC24-106, -109, -110, and -111, drilled on the northern portion of the trend were too far east to reach the mineralized structures. Drillhole TXC24-108 cut multiple veins, but returned values below the cut-off grade (0.31 metres grading 117 g/t Ag, 0.165 g/t Au for 132 g/t AgEq; 0.67 metres grading 73 g/t Ag, 0.263 g/t Au for 96 g/t AgEq; and 0.64 metres yielding 50 g/t Ag, 0.24 g/t Au for 72 g/t AgEq starting at 578m, 590m and 631m respectively). TXC24-112 was drilled in a northwesterly direction and deviated to the northwest thereby paralleling the main structural grain. One drillhole, TXC24-107, which was cored from surface was lost before reaching the target depth.

With drillholes TXC24-113, -114 and TXC25-123 and -124 cutting multiple high-grade veins, the exploration group has a better understanding of the geometry of the NW Step Out structures that will be used for refined targeting of our expanded Resource Expansion Program.

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.

Blackrock Silver Commences Eastern Expansion Drill Program Targeting 1.2km Trend at Tonopah West

Scout Drilling Discovered the Extension of the High-grade Merten Vein Creating an Opportunity to Expand the Dpb Resource up to 1,200 Metres to the East

SCOUT PROGRAM HIGHLIGHTS:

  • Assay results from the Company's reverse circulation Scout Drill Program (see March 31, 2025 news) returned significant gold & silver values in 7 drillholes that successfully expanded the footprint of mineralization up to 1,200 metres from the east of the existing DPB resource toward the historic Ohio mine;

  • These intercepts cover a new zone of silver and gold interpreted to be the outer ring structure of the Fraction caldera, and are not included in the 2024 resource;

  • A fully funded 15 drillhole program totalling up to 5,000 metres is underway; and

  • Results from this program will be incorporated into an updated Mineral Resource Estimate in Q1, 2026.

Vancouver, British Columbia--(Newsfile Corp. - July 21, 2025) - Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") announces commencement of a fully-funded expansion drill program ("Expansion Program") to follow up on the successful Scout Drilling campaign that expanded the DPB South zone 1,200 metres in an easterly direction on its 100% owned Tonopah West project located in Nye and Esmeralda Counties, Nevada, United States.

The Expansion Program will utilize one Reverse Circulation (RC) drill overseen by Legacy Drilling and two core drill rigs operated by Alloy Drilling to complete 2,450 metres (8,000 ft) of RC precollars and 2,550 metres (8,400 ft) of core tails across 15 drillholes targeting the Eastern Expansion zone between the DPB resource area and the eastern extent of the project. Drilling is anticipated to be completed in October with assay results expected through year end.

Andrew Pollard, Blackrock's President and CEO, stated, "With drills now turning on this fully financed program, we're stepping out across a 1.2-kilometre corridor with strong potential to significantly expand our mineral inventory at Tonopah West. Scout drilling confirmed the eastern extension of the high-grade Merten vein well beyond the current resource boundary, returning standout grades including 2,063 grams per tonne (g/t) silver equivalent (AgEq) (1,198 g/t silver (Ag) and 9.6 g/t gold (Au)) over 1.52 metres, and 952 g/t AgEq (10 g/t Ag and 10.5 g/t Au) over 4.57 metres. This newly defined zone, situated along the outer ring structure of the Fraction caldera, lies entirely outside our 2024 resource and presents an opportunity to quickly and meaningfully grow the scale of the project. Results from this program are expected to underpin a resource update in Q1 2026. The Company remains on track to deliver a separate resource update in Q3 2025 that will incorporate all results from the recently completed M&I conversion program."

As announced on March 31, 2025, the Company discovered the 1,200 metre eastern extension zone representing the continuation of the outer-ring structure or Fraction caldera margin from DPB South to the historic Ohio mine. The Scout Drilling showed the Merten vein extends eastward and is arched and dips southward. This orientation suggests multiple ring structures associated with the Fraction caldera running across Tonopah West. 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 (See Figure 1). 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. Table 1 summarizes the Scout Drilling assay results above 150 g/t AgEq.

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), and show mineralization extends along the Merten vein for 540 meters 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 length.

The mineralized zone traced by these assay results is new and not included in the 2024 resource. These results could have a substantive impact on the future resource estimate.

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.
