The 2025 Exploration Program at the Samapleu-Grata Nickel-Copper Project Identifies New Polymetallic Mineralization 10 kilometers to the South-Southwest of the Existing Mineral Resources

Executive Summary

• Discovery of significant polymetallic mineralization at the Mossikro Prospect (10 km SSW of existing deposits) and additional mineralization southwest of the Samapleu Extension Deposit.
• Drill hole results include multiple intercepts with notable CuEq grades (e.g., 5.62 m @ 0.67 % CuEq, 99.55 m @ 0.48 % CuEq).
• The 2025 program still has ~3,000 m of infill drilling planned at the Grata Deposit to upgrade Inferred Resources to Indicated Resources, supporting future permitting and economic studies.

Key Details

• Joint Venture: Sama Resources (40%) – Ivanhoe Electric (60%); Ivanhoe also holds 22.7 % of Sama’s common shares.
• Exploration Scope: 4,500 m total planned drilling; ~840 m completed to date at Mossikro and Samapleu Extension.
• Mossikro Prospect – Hole S‑354: 5.62 m @ 0.67 % CuEq from 167.28 m depth (Ni cut‑off 0.10 %).
• Mossikro Prospect – Hole S‑355: 5.90 m @ 0.29 % CuEq from 184.25 m depth; includes 1.25 m @ 0.80 % CuEq.
• Samapleu Extension – Hole S‑353: 99.55 m @ 0.48 % CuEq from 15.55 m depth; includes 7.15 m @ 1.27 % CuEq and several higher‑grade sub‑intervals (e.g., 0.30 m @ 2.69 % CuEq).
• Future Drilling: ~3,000 m infill program at Grata Deposit slated for fall 2025 to convert Inferred Resources (~67.3 Mt @ 0.24 % Ni, 0.25 % Cu, etc.) to Indicated Resources.
• Environmental Work: Ongoing baseline studies (wildlife, vegetation, water) completed by SIMPAE to meet permitting standards.
• Assay Methodology: Core logging in‑field; samples sent to Bureau Veritas (Abidjan) and Activation Laboratories (Ontario) for ICP and fire‑assay analyses.
• Technical Review: Dr. Marc‑Antoine Audet, Ph.D., President & CEO of Sama, qualified person under NI 43‑101, reviewed the technical information.

Notable Quotes

“The discovery of Samapleu‑like polymetallic mineralization at the Mossikro Prospect is further testament to the regional prospectivity of the broader Samapleu‑Grata Project.” – Dr. Marc‑Antoine Audet, President & CEO, Sama Resources.
