Welcome to The
Silver State
Fraser Institute Annual Survey of Mining Companies 2025, Nevada has reclaimed the #1 spot as the most attractive mining jurisdiction in the world (Investment Attractiveness Index).
Tonopah West represents the largest patented claim package in the Tonopah Silver district, 100 patented and 279 unpatented claims covering 25.5 km2.
Tonopah Silver District: One of the largest historic silver districts in North America, producing 174 Mozs Ag & 1.8 Mozs Au from 7.5m tonnes
Mined from underground from 1900 to 1930, with peak years producing up to 14,000,000oz/ year AgEq; Victor vein was 24m thick where production ceased
A 2026 Updated Preliminary Economic Assessment (PEA)* outlines an average annual production profile of 7.1 million silver equivalent ounces per year at an all-in sustaining cost of USD$17.44 per AgEq ounce over an 11.2 year mine life.
The project currently hosts an indicated mineral resource estimate of 2.75 million tonnes at a block diluted grade of 216.8 grams per tonne (g/t) silver (Ag) and 2.25 g/t gold (Au) for a total of 19,167,000 ounces of silver and 199,000 ounces of gold. In addition, the project currently hosts an inferred mineral resource of 5.5 million tonnes at a block diluted grade of 188.5 g/t Ag and 2.62 g/t Au for a total of 33,560,000 ounces of silver and 467,000 ounces of gold.


#1 Mining Jurisdiction
in the World
Nevada has reclaimed the #1 spot as the most attractive mining jurisdiction in the world (Fraser Institute Annual Survey of Mining Companies 2025), combining exceptional geologic mineral potential with highly favorable government policies.
Tonopah West represents the largest patented claim package in the Tonopah Silver District, comprising 100 patented and 279 unpatented claims covering 25.5 km².
Known as the Queen of the Silver Camps, the Tonopah Silver District is one of the largest historic silver districts in North America, having produced 174 Moz Ag and 1.8 Moz Au from 7.5 million tonnes.
Mining ran from 1900 to 1930, with peak years reaching up to 14,000,000 oz/year AgEq — and the Victor vein was still 24m thick where production ceased.

Resource Estimate
Certain scientific and technical information relating to the MRE and the PEA on the Tonopah West Project contained in this presentation is derived from the Company's press release titled "Blackrock Silver Announces Updated Preliminary Economic Assessment For Its Tonopah West Project In Nevada; +10 Year Mine Life Fortified By 90% Increase In Indicated Mineral Resources" dated March 31, 2026. Details of the PEA and MRE will be provided in a technical report prepared in accordance with NI 43-101 to be filed on SEDAR+ and the Company's website within 45 days of March 31, 2026.
All historic production information from Nevada Bureau of Mines & Geology, Bulletin 51 and Bulletin 92. US short tons have been converted to metric tonnes by multiplying short tons by 0.9072 AgEq = (historic gold production times historic gold price) divided by historic silver price) plus historic silver production . Production figures representative of entire district.

1. AgEq cutoff grade is based on total mining, processing and G&A costs of $128.6/tonne and a silver price of $34/ounce.
2. For non-Victor areas a Silver Equivalent grade ratio used is 108:1 based on silver and gold prices of $35/ounce and $3,500/ounce, respectively, and recoveries for silver and gold of 88% and 95%, respectively. For the Victor area, Silver Equivalent grade ratio used is 102:1 based on silver and gold prices of $35/ounce and $3,500/ounce, respectively, and recoveries for silver and gold of 96% and 98%, respectively. AgEq Factor= (Ag Price / Au Price) x (Ag Rec / Au Rec); g AgEq/t = g Ag/t + (g Au/t / AgEq Factor).
3. Rounding as required by reporting guidelines may result in apparent discrepancies between tonnes, grade, and contained metal content.
4. Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources estimated will be converted into mineral reserves. The quantity and grade of reported Inferred mineral resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred mineral resources as Indicated mineral resources. It is uncertain if further exploration will result in upgrading them to the Indicated mineral resources category.
