Nord Precious Metals Mining (TSX-V:NTH) reports ‘high-grade’ silver-cobalt intervals from wedge hole CS‑26‑140W1 at its Castle East Project near Gowganda, Ontario, Canada.
The hole returned 4,683 grams per tonne silver (Ag) with 0.53% cobalt (Co) over 2m between 404.2m and 406.2m downhole. This includes 20,676g/t Ag with 1.16% Co over 0.3m and 6,159g/t Ag with 2.32% Co over 0.3m.
A lower interval graded 4,540g/t Ag with 0.24% Co over 0.9m, including 10,414g/t Ag with 0.72% Co over 0.3m, within a broader 4.2m interval averaging 1,546g/t Ag. A middle interval returned 1,560g/t Ag over 0.3m.
The three intervals occur across a 59.4m downhole span and are not continuous mineralisation. The company interprets the intersections in relation to the Robinson structure and the Big Silver structure, a parallel silver-bearing plane east of the Robinson Zone.
The intersections lie approximately 9m from a 914g/t Ag intercept in hole CS‑21‑92 and 10m from a 992g/t Ag intercept in hole CS‑20‑43.
Visual logging documented native silver stringers and millimetre‑scale silver flakes around calcite veins, with native silver concentrated along vein contacts.
CEO Frank Basa says the results provide important new data for the Castle East model and complete the sequence the company has been building.
“CS-26-140W1 adds three separate high-grade silver-cobalt intervals across a 59.4m downhole span and gives our technical team important new data for the Castle East model,” Basa notes.
“Set beside the surface gold work and the conceptual open-pit assessment, it completes the sequence we have been building: gold at surface, near-surface evaluation, and high-grade silver at depth.”
The hole continues a model-led drilling sequence following the company’s 2025 three‑dimensional modelling review of more than 75,000m of drilling and 29 modelled veins.
Recent results include 2,344g/t Ag over 1.85m, 2,848g/t Ag over 6.65m, and 13,620g/t Ag with 1.84% Co over 0.6m.
Nord operates TTL Laboratories, the only permitted ‘high-grade’ milling facility in Ontario’s Cobalt Camp.
Results from CS‑26‑140W1 are being incorporated into the expanded Castle East geological model, with follow‑up work focusing on continuity and orientation of the mineralised intervals.
