Sankamap completes survey data processing at Kuma

Executive Summary

• Sankamap Metals Inc. reports the completion of data processing for a 374-line-kilometre airborne magnetotelluric (MT) electromagnetic survey conducted in July 2025 on its Kuma property in the Solomon Islands.
• The survey results highlight a broad, ring-shaped zone of high conductivity flanking a central resistive feature, which the company interprets as consistent with porphyry-style mineralization, including potential intrusive centres and structural controls.
• The company is advancing its strategic plan with a $4.7-million financing closed in October 2025, targeting an inaugural drilling campaign scheduled to commence in January 2026, following pad and camp construction in late November.

Key Details

• Survey Specifications:
  • Conducted by Expert Geophysics in July 2025.
  • Covered 374 line-kilometres along north-south lines at 100-metre intervals.
  • Covered 3,500 hectares of the 4,500-hectare Kuma property (excluding populated areas).
• Geophysical Findings:
  • Identified a broad five-by-two-kilometre ring-shaped zone of high conductivity flanking a central two-by-three-kilometre highly resistive feature.
  • The conductive feature spatially correlates to the mapped lithocap.
  • Data indicates potential for multiple intrusive centres and porphyry systems.
  • Alignment of magnetic and conductive trends suggests structural controls or fluid pathways associated with mineralization.
  • Resistive and conductive trends display typical porphyry signatures similar to other economic porphyry systems.
• Geological Context & Corroboration:
  • Results corroborate earlier surface exploration findings, including a well-developed lithocap exceeding two kilometres in extent.
  • Hyperspectral analysis outlines extensive phyllic, argillic, and advanced argillic alteration zones.
  • Historical grab sampling returned assay results of up to 11.7% copper and 13.5 grams per tonne gold.
  • The Kuma project is located along a trend hosting major deposits: Lihir (71 million ounces Au) and Panguna (19.3 Moz Au plus 5.3 Mt Cu).
• Strategic Plan & Timeline:
  • Financing: $4.7-million financing closed on October 3, 2025.
  • Equipment: Acquisition and deployment of drilling equipment underway.
  • Logistics: Pad and camp construction scheduled to begin in late November 2025.
  • Field Work: Planned field visit for early November 2025 to ground-truth targets and finalize logistics.
  • Drilling: Inaugural drilling campaign to commence in January 2026.
• Other Property Activity:
  • Fauro Property: Prospecting activities to begin, following up on magnetic highs associated with elevated gold and copper values.
• Corporate Actions:
  • Grant of 2.25 million stock options to directors, officers, and consultants, exercisable for five years at a price of 30 cents (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. The strong alignment between these geophysical features, surface geochemistry and alteration mapping gives us greater confidence in the continuity of mineralization at depth and helps refine our upcoming drill targets." — John Florek, Chief Executive Officer
