Comstock Project

Comstock Historic Drilling (Original-Diane, 1988)

Limited, shallow drilling has been conducted on the Comstock property to date
In 1988, a 9-hole drill program totaling 570 m was carried out at the Original-Diane
Copper values exceeding 1% were never re-assayed and only ~22% of the drill core was assayed
Despite the shallow drilling and limited analytical work at the time, the program returned encouraging copper and gold intercepts, underscoring the strong underlying potential of the Original-Diane Zone.

Limited historical drilling delivered strong copper-gold grades

1988, 9-holes totaling 570 m with 90 m max depth
Drilling stopped in mineralization
Solely targeted trench discoveries
24.7 g/t Au over 0.75 m, ≥ 2 g/t Au over 0.62 m, 0.91 m, and 1.07 m
≥ 1% Cu over 0.61 m, 0.92 m, 1.0 m, 1.22 m
All 9 shallow drill holes intercepted copper-gold mineralization, despite only 22% of the drill core being assayed
Multiple intercepts reporting copper values exceeding 1.0% were never re-assayed

Results obtained from Nelles, 1988 (AR17721). *Drill core assays were capped at 10,000 ppm Cu (1%) and approximately only 22% of the total 570 metres of core was assayed. The estimated true width of mineralization is unknown.
