Blackrock Silver Drills Multiple +1 kg/t AgEq Intercepts and Establishes Grade Continuity over 350 Metres in Final M&I Conversio

  • Final Assay Results from the M&I Conversion Program Confirm High-Grade Continuity of Gold and Silver Mineralization over 350 Metres in the M&I Conversion Area HIGHLIGHTS: TXC25-139 cut 9.05 metres grading 367 grams per tonne (g/t) silver equivalent (AgEq) (182.8 g/t silver (Ag) & 2.04 g/t gold (Au)) from 187.5 metres, including 0.82 metres grading 2,886 g/t AgEq (1,411 g/t Ag & 16.13 g/t Au), Ag/Au ratio 90:1; TXC25-150 drilled 2.84 metres grading 671.5 AgEq (367 g/t Ag & 3.41 g/t Au) from 162.3 metres, including 0.76 metres grading 1,554 g/t AgEq ( 819 g/t Ag & 8.14 g/t Au); TXC25-146 intercepted 1.16 metres of 1,111 g/t AgEq (615 g/t Ag & 5.50 g/t Au) from 189.5 metres; Results from the entirety of the M&I Conversion Program have validated the geologic model, successfully establishing continuity of the high-grade shoots bearing robust geometry over 350 metres. The shoots remain open to the Northwest and downdip; Significant new zones of near-surface mineralization were encountered during the M&I Conversion Program at higher-than-average grades updip from the existing resource shell; Modelling of the M&I Conversion Program drillholes is now underway with an updated mineral resource estimate on Tonopah West on track for Q3, 2025; and Assay results for 7 drillholes from the Company's Northwest step out resource expansion area are currently pending.
