Sankamap Announces Airborne Geophysical Survey Results Highlighting Promising Anomalies

Executive Summary

• Sankamap Metals completed processing of a 374 km airborne Magnetotelluric EM (Mobile MT) survey over the 4,500‑ha Kuma property, revealing a 5 × 2 km conductive ring and central resistive feature consistent with porphyry Cu‑Au mineralization.
• Surface geochemistry continues to show high‑grade assays (up to 11.7 % Cu and 13.5 g/t Au), reinforcing confidence in the continuity of the system and guiding drill target definition.
• The company has secured $4.7 M financing (Oct 3, 2025) and plans a January 2026 drilling campaign, with pad & camp construction slated for late November 2025.

Key Details

• Survey Coverage: 374 line‑km Mobile MT survey flown July 2025 over 3,500 ha of the Kuma property (excluding populated areas).
• Geophysical Highlights:
• Broad 5 × 2 km conductive zone flanking a central 2 × 3 km resistive body – interpreted as a potassic intrusive core surrounded by conductive alteration halos.
• Conductivity and magnetic trends suggest multiple intrusive centers, structural controls, and fluid pathways typical of porphyry systems.
• Correlation with Surface Data:
• Conductive anomaly aligns with mapped lithocap and advanced argillic/clay‑mica alteration zones.
• Grab samples from the property returned up to 11.7 % Cu and 13.5 g/t Au, supporting the geophysical model.
• Comparative Context: Kuma lies on a trend that hosts Lihir (71 Moz Au) and Panguna (19.3 Moz Au + 5.3 Mt Cu), indicating similar geological potential.
• Technical Interpretation: Porphyry Cu‑Au systems with intact lithocaps often exhibit conductive halos; the observed resistive core likely represents a magnetite/K‑feldspar altered zone with low sulfide content.
• Financing: $4.7 M financing closed on 2025‑10‑03, providing capital for exploration activities beginning November 2025.
• Upcoming Exploration Milestones:
• Pad & Camp Construction: Late November 2025.
• Field Visit: Early November 2025 to ground‑truth targets and finalize logistics.
• Drilling Campaign: Inaugural drill program commencing January 2026, targeting high‑priority zones identified from the Mobile MT data.
• Fauro Property Update: Prospecting to start following magnetic highs linked to elevated Au/Cu values (referencing July 16, 2025 press release).
• Option Grant: 2,250,000 stock options granted to directors/officers/consultants at $0.30 per share, subject to regulatory approval.

Notable Quotes

“We are very encouraged by the results of the airborne geophysical survey, which reveal clear signatures consistent with porphyry‑style mineralization… gives us greater confidence in the continuity of mineralization at depth and helps refine our upcoming drill targets.” – John Florek, CEO
