Nord Precious Metals completes radar survey at Castle

Executive Summary

• Nord Precious Metals completed a four‑day deep ground penetrating radar (DGPR) orientation survey at the Castle property to map historic underground workings down to ~100 m depth.
• The survey aims to identify mineralized stopes, fractures, vein extensions, and lithologic contacts that will guide upcoming sonic drilling of historic tailings and future back‑fill operations.
• Results will be delivered by Earth Scan Technologies as maps, vertical sections, and a 3‑D model; the data may support expansion of the survey area pending findings.

Key Details

• Survey Scope: DGPR conducted with Earth Scan Technologies; penetrates to 200 m, targeting upper four levels (21 m & 48 m depths) of historic mine openings at Castle.
• Objectives:
• Distinguish mineral‑filled versus empty stopes.
• Map fractures and potential new vein structures or extensions.
• Delineate Nipissing diabase contact, source of high‑grade silver mineralization.
• Data Deliverables: Final report with maps, vertical sections, interpretations of stope/vein characteristics, and a 3‑D model (contingent on data density).
• Integration with Future Work: Survey results will be combined with an upcoming sonic drill program on Miller Creek tailings to assess recovery of silver and critical metals.
• Remediation Plan: Using Ontario’s new recovery permit, Nord intends to process historic tailings into a high‑grade silver gravity concentrate containing critical metal sulfides, then backfill empty stopes with cemented tailings for ground stabilization.
• Survey Duration: Completed in four days on site; potential expansion if depth detail and vein identification warrant further work.
• Qualified Person: Frank J. Basa, P.Eng., (Peo), director of Nord Precious Metals, approved the technical information per NI 43‑101.
