Blackrock Silver (BRC) Mining Forum Americas 2026 summary

Project milestones and resource growth

• Advanced from initial drill hole to over 123 million silver equivalent ounces in six years, marking the largest and highest-grade silver discovery in America in decades.

• Transitioned from conceptual engineering to imminent underground development, with ground-breaking planned for next year.

• Resource footprint expanded to 5.5 km of cohesive mineralization, with a current market cap between CAD 400–500 million and CAD 20 million in cash.

• Inclusion in major ETFs and coverage by leading financial institutions, reflecting increased prominence and investor confidence.

• Board strengthened with experienced industry leaders in preparation for transition to a major exchange listing.

Historical context and district significance

• The district, discovered in 1900, is renowned for its ultra-high-grade silver, producing 400 million silver equivalent ounces by 1930.

• Historic production achieved a 100:1 silver to gold ratio, with 178 million ounces of silver and 1.8 million ounces of gold from just 7.5 million tons.

• Mining ceased in the 1930s due to technical limitations, not resource depletion, leaving significant unmined extensions.

• The project consolidates these unmined extensions, now proven to contain about 125 million ounces of silver equivalent.

Economic and technical highlights

• Updated PEA (March 2026) projects an after-tax NPV over $1.55 billion, with annual production of 7–8 million ounces over 11 years at all-in sustaining costs below $17.50/oz.

• High-margin, low-cost operation with a block-diluted grade just under 0.5 kg/ton and simple metallurgy, all on private land for expedited permitting.

• Payback period projected at just over one year, with a manageable CapEx of CAD 190 million and robust economics across metal price scenarios.

• One-third of ounces now indicated, mine life extended by 40% through targeted drilling, and environmental baseline work well advanced.
