Blackrock Silver Corp. advances the high-grade Tonopah West Project in Nevada as an American-focused primary silver developer. Company news centers on Tonopah West mineral-resource work, NI 43-101 preliminary economic assessment updates, expansion drilling, permitting activity and technical programs tied to potential silver and gold development in the historic Tonopah mining district.
Blackrock Silver updates also cover governance and capital-compensation matters, including board appointments and deferred share units under its omnibus equity incentive plan. Sector commentary may place BKRRF among silver and polymetallic exploration companies affected by silver supply, critical-minerals demand and Nevada project-development themes.
Blackrock Silver (OTCQX: BKRRF) has begun Phase 2 hydrology, geotechnical and seismic programs at its 100% owned Tonopah West project, Nevada, to advance permitting for an exploration decline, test mining and a bulk sample.
Key actions include installing 5 additional piezometers, a dewatering well and a monitoring well; geotechnical evaluation on 22 drillholes and 36 geotechnical samples; and an 18 km, seven-line 2D seismic survey. An updated preliminary economic assessment is scheduled for Q1 2026.
Blackrock Silver (BKRRF) filed an independent NI 43-101 technical report titled "Mineral Resource Estimate Update, Tonopah West Silver-Gold Project" on SEDAR+ with an effective date of August 25, 2025 and a report date of October 22, 2025.
The report covers the company’s 100%-owned Tonopah West project, was prepared to CIM and NI 43-101 standards, supports the September 8, 2025 updated mineral resource disclosure, and reports no material differences from that September disclosure. The report is available on SEDAR+ and the company website.
Blackrock Silver (OTCQX: BKRRF) says Canada Post strike may prevent mailing of proxy and annual report materials for its Annual General Meeting on November 21, 2025 at 11:00 a.m. Vancouver time.
The company posted electronic Meeting Materials and Financial Statements and MD&A on SEDAR+ and its website and will provide copies by email on request. It is relying on CSA Blanket Order 51-932 and has waived the proxy cut-off time: proxies must be received by Computershare by 11:00 a.m. Vancouver time on November 20, 2025 or delivered to the chair before the meeting.
Blackrock Silver (OTCQX: BKRRF) has announced an updated mineral resource estimate for its 100% owned Tonopah West project in Nevada. The new estimate shows 21.1 million ounces of silver equivalent (AgEq) in indicated resources and 86.88 million ounces AgEq in inferred resources.
The indicated resources grade at 493 g/t AgEq, containing 0.107 million ounces of gold and 9.5 million ounces of silver. The inferred resources grade at 525.9 g/t AgEq, comprising 0.47 million ounces of gold and 35.5 million ounces of silver. The estimate includes 83 new drillholes completed in 2024-2025.
The mineralization remains open to the northwest, east, internally between main bodies, and at depth. The company plans to pursue permits, refine engineering designs, and advance to the next phase including an exploration decline and test mining.
Blackrock Silver (OTCQX: BKRRF) has received C$4.24 million from warrant exercises and expanded its Eastern Expansion drill program at the Tonopah West project in Nevada. The company has completed 19 out of 22 planned drillholes in the expanded program, which now targets up to 7,000 metres of drilling in the 1.2-kilometre Eastern Expansion zone.
The warrant exercises resulted in the issuance of 9,830,880 common shares, bringing the total outstanding shares to 325,490,026. Additionally, 5,733,000 warrants with an exercise price of C$0.75 expired unexercised on September 2, 2025. The company expects to release an updated mineral resource estimate in early September 2025, followed by another update in Q1 2026.
Blackrock Silver (OTCQX: BKRRF) has initiated a fully-funded expansion drill program at its Tonopah West project in Nevada, following successful scout drilling that extended the DPB South zone by 1,200 metres eastward. The program will utilize three drill rigs to complete 5,000 metres of drilling across 15 holes.
Scout drilling revealed significant results, including 2,063 g/t silver equivalent over 1.52 metres and 952 g/t silver equivalent over 4.57 metres. The newly defined zone, located along the outer ring structure of the Fraction caldera, lies outside the 2024 resource and presents substantial growth potential. The program is expected to complete in October, with results incorporated into a Q1 2026 resource update.
Blackrock Silver (OTCQX: BKRRF) has announced significant drilling results from its Resource Expansion Program at the Tonopah West project in Nevada. The program's final assays confirmed high-grade silver and gold mineralization extending 500 metres beyond the current DPB resource.
Key highlights include intercepts of 10.12 metres grading 467 g/t silver equivalent (including 3.51 metres of 1,020 g/t AgEq) and 11.58 metres grading 327 g/t AgEq (including 0.67 metres of 3,264 g/t AgEq). The 18-drillhole program, totaling 10,802 metres, has established continuity of mineralization along a significant portion of the one-kilometer northwest trend.
The company is now targeting the remaining 500-metre gap of vein corridor to fully bridge mineralization to the NW Step Out deposit, with potential to materially expand the resource and extend mine life at Tonopah West.
Blackrock Silver (BKRRF) has initiated a core drilling program for piezometer installation at its Tonopah West project in Nevada. The program includes four core holes totaling 1,565 metres and represents a crucial step in the permitting process for the proposed exploration decline, test mining, and bulk sample extraction.
The piezometers will be strategically placed to measure water flow along faults, lithologic contacts, and specific lithologies. The collected data will address water management questions for underground mining, including permitting requirements, engineering design, and water disposal solutions. This initiative demonstrates Blackrock's commitment to advancing the high-grade silver-gold asset while maintaining environmental and regulatory compliance.
Blackrock Silver Corp. (BKRRF) has reported significant high-grade silver and gold drill results from its M&I Conversion Program at the Tonopah West project in Nevada. Key highlight includes drillhole TXC25-138, which returned 4.24 meters grading 700 g/t silver equivalent, including 0.31 meters of 3,182 g/t AgEq, and 5.18 meters grading 556 g/t AgEq.
The company is completing a 62-drillhole infill program at the DPB South resource area, aiming to convert up to 1.0-million tonnes from inferred to measured and indicated resources. Notably, TXC25-138 delivered the thickest composite zone drilled in the district outside the historic Victor mine, with 11.46 metres of 514 g/t AgEq. The company expects to complete an updated mineral resource estimate in Q3 2025, with ten drillholes still pending assays from the M&I program and seven from the Resource Expansion program.
