Blackrock Silver – Final Set Of Drill Assays From Eastern Expansion Step Out Program, Building Towards Expanded Resource Estimate And Updated PEA In Q1 2026
Andrew Pollard, President and CEO of Blackrock Silver (TSX.V:BRC – OTCQX:BKRRF), joins us to discuss the final set of diamond core drill assays, from this year’s exploration program, stepping out into the Eastern Expansion area at their 100% owned Tonopah West project located in West-Central Nevada, United States. The Eastern Expansion Program was a follow-up to the Company’s reverse-circulation scout drill program at Tonopah West completed in February 2025, which showed significant potential to expand the DPB South resource area 1,200 metres in an easterly direction.
EASTERN EXPANSION PROGRAM HIGHLIGHTS:
At least three mineralized northwest oriented structures have been identified within the 1.2 kilometre eastern expansion trend running parallel to the Pittsburg-Monarch fault that suggest a series of footwall fault splays as opposed to a singular east-west structure;
TXC25-173 cut 0.92 metres of 2,122.7 grams per tonne (g/t) silver equivalent (AgEq) (1,162 g/t silver (Ag) & 8.79 g/t gold (Au)) from 220.9 metres, and a separate zone of 1.04 metres grading 534.8 g/t AgEq (189.8 g/t Ag & 3.16 g/t Au) from 215.5 metres;
TXC25-178 drilled 6.4 metres of 296.6 g/t AgEq (135.7 g/t Ag & 1.47 g/t Au), including 0.46 metres of 3,853 g/t AgEq (1,771 g/t Ag & 19.06 g/t Au) from 183.8 metres in a north-south oriented structure within the M&I Conversion Area at DPB South; and
Results from the Company's drill program targeting expansion potential across a one kilometre trend of vein corridor between the DPB and Northwest Step Out resource areas and the Eastern Expansion Program will be incorporated into an updated mineral resource estimate and preliminary economic assessment on Tonopah West estimated to be completed in February 2026.
Andrew reiterates that the silver and gold mineralization at Tonopah West remains open to the northwest, east and internally between the main bodies of mineralization, as well as at depth. He also highlights how this new understanding of the North-South orientation to mineralization in the Eastern Expansion area that will inform next year’s follow up drilling. We also discuss how with more drilling this area could be important earlier on in the mining development sequencing.
As it stands today, before all this expansion drilling gets included, the updated MRE released in September, based on just the M&I conversion drilling, contains a total of 0.107 million ounces (“Mozs”) of gold (“Au”) and 9.5Mozs of silver (“Ag”), or 21.1Mozs of silver equivalent (“AgEq”) of indicated mineral resources, and 0.47 Mozs of Au and 35.5Mozs of Ag, or 86.88Mozs of AgEq of inferred mineral resources.
We discussed that this Tonopah West Project really works even at far lower silver and gold prices due to the very high-grade nature of the deposit, and has excellent torque to rising metals prices. At a 180 grams per tonne (“g/t”) AgEq cutoff, the average block-diluted grade of the indicated mineral resources is 493 g/t AgEq and the average block-diluted grade of the inferred mineral resources is 525.9 g/t AgEq. This actually keeps the proposed head grade at much higher levels than other peer development projects, once the economics and stope optimization process is factored in.
The Company is engaged in many derisking and development activities from hydrology and geotechnical drilling, to permitting, engineering, metallurgical studies, and this will all be factored into the updated Preliminary Economic Assessment due out in February of 2026.
