Fathom Nickel extends Gochager Lake over 3.5 km

Executive Summary

• Fathom Nickel Inc. has updated its geology map for the Gochager Lake project, confirming that the historic deposit's host rock (variable-textured gabbro) extends along a minimum 3.5-kilometer strike length northeast of the historic deposit.
• The company received all assay results from its July 2025 exploration program and is awaiting rock assay and whole-rock geochemistry results from a September-October prospecting campaign, expected in mid-November.
• The expansion of the "container rock" along this strike length, combined with untested borehole electromagnetic (BHEM) anomalies, suggests significant potential for additional high-grade Ni-Cu-Co sulphide mineralization, including massive sulphide veins and breccias.

Key Details

• Host Rock Extension: The historic Gochager Lake deposit host rock (variable-textured gabbro) has been mapped consistently along a northeast strike for a minimum distance of 3.5 kilometers.
• Geological Context: The mineralized variable-textured gabbro continues toward and under Scurry Lake, south of Rainbow Lake, and to the north shore of Weaver Lake. Clotted gabbro, which defines the footwall lithology at the historic deposit, is mapped in direct contact with the variable-textured gabbro along much of this 3.5 km strike.
• Wildfire Impact: A wildfire in late July 2025 resulted in significant new outcrop exposure, facilitating a second prospecting campaign from Sept. 25 to Oct. 1, 2025.
• Sampling Data:
  • 684 outcrop chip samples were collected and analyzed on-site using pXRF.
  • 79 rock grab samples (including standards and blanks) were submitted for multielement assay and whole-rock geochemistry.
• Historic Drill Intersects:
  • Hole GL23008: 0.64 m at 3.25% Ni, 0.26% Cu, 0.11% Co in a massive sulphide vein.
  • Hole GL24016: 7.39 m at 1.43% Ni, 0.38% Cu, 0.11% Co, including 2.94 m at 2.43% Ni, 0.55% Cu, 0.19% Co in semi-massive to massive sulphide breccias.
• Future Targets: Fathom drill hole GL23011, drilled near the well-mineralized variable-textured gabbro on the west shore of Scurry Lake, identified three prominent off-hole conductivity anomalies via BHEM survey that remain untested. The company believes the expanded container rock has the potential to yield similar high-grade sulphide breccia mineralization and massive sulphide bodies.
• QA/QC: The company utilized a portable Vanta XRF analyzer for real-time lithogeochemical data on surface rock chip and grab samples.
