Canuc Reports on MacDonald Mines Acquisition

Executive Summary

• Canuc Resources reports the acquisition and initial geological review of its wholly‑owned East Sudbury Project (ESP), encompassing ~197 km² of mining claims and leases in eastern Sudbury, Ontario.
• The ESP contains extensive historic drill data (32,685 m from 213 holes) and multiple high‑grade gold and copper‑gold targets, including the Alwyn Cu‑Au prospect (4.2 m @ 1.07 % Cu & 3.01 g/t Au) and Gold Lens 1 (36.27 g/t Au over 12.27 m).
• A 15‑hole drill program targeting Gold Lens 1 is slated to start in early October 2025, aiming to define a maiden resource for the high‑grade gold zone.

Key Details

• Acquisition: 100 % ownership of ESP obtained on 8 May 2025 via purchase of MacDonald Mines.
• Land Package: 906 unpatented mining claims + 6 mining leases covering ~19,710 ha (≈197 km²).
• Historical Data:
• 117 drill holes (20,688 m) by MacDonald Mines (2019‑present).
• 96 holes (10,304 m) by Trueclaim Exploration Ltd.
• 1,693 m from Northern Sphere Mining.
• Total core stored on‑site: 32,685 m across 213 holes.
• Geology: Predominantly Paleoproterozoic Huronian Supergroup intruded by Nipissing Diabase; metasomatic iron‑alkali‑calcic (MIAC) system providing IOCG potential.
• Key Targets & Intercepts:
• Alwyn Cu‑Au Prospect – historic production 6,300 t @ 1 % Cu & 5.67 g/t Au (1902). Recent drilling: AW‑22‑102 intersected 4.2 m @ 1.07 % Cu & 3.01 g/t Au; broader zone 0.16 % Cu & 0.36 g/t Au over 90.44 m.
• Ashigami Prospect (grab samples): 3.11‑5.55 % Cu, 1.00‑6.45 g/t Au.
• Crerar Prospect (grab samples): up to 4.09 % Cu & 3.1 g/t Au.
• Gold Lens 1 (Scadding Gold Mine) – SM‑19‑001: 36.27 g/t Au over 12.27 m (incl. 221.4 g/t Au over 1.9 m). Estimated true thickness ≈80 % of intersected width.
• Gold Lens 2 (Glade Prospect) – AG‑22‑97: 113 g/t Au over 0.96 m; lower interval 5.17 g/t Au over 22.67 m.
• Planned Drilling: 15‑hole program commencing Oct 2025 to verify and expand Gold Lens 1, with the goal of calculating a maiden resource. Additional work planned on Lenses 2 & 3 and other fault‑related targets.
• AI Targeting (2022): ALS Goldspot identified five high‑priority zones; limited field follow‑up completed to date.
• Assay Verification: 86 mineralized intervals submitted for re‑assay; core integrity and collar locations verified via GPS.
• Infrastructure: On‑site office, warehouse, core logging facility, power access, maintained roads, and groundwater resources available.

Notable Quotes

“The East Sudbury Project hosts multiple historical high‑grade gold and copper mines… we have identified several new high‑grade gold zones… there is a growing body of evidence to support an IOCG model for ore genesis.” – Chris Berlet, CEO & Director

“We are setting up to recover gold profitably from historic tailings and advancing studies to quantify unmined, high‑grade Gold Lenses.” – Chris Berlet
