Fathom releases preliminary soil geochemistry results

Executive Summary

• Fathom Nickel Inc. released preliminary results from its 2025 soil geochemistry program at the Gochager Lake project, expanding the favorable geochemical footprint to a strike length exceeding 8.6 kilometers.
• The results validate the company's hypothesis that the historic Gochager Lake deposit is part of a larger, highly prospective mineralized trend with potential for multiple magmatic Ni-Cu-Co sulphide deposits.
• A new, robust nickel-in-soil anomaly measuring 1,500 m by 400 m was discovered approximately 2.7 km southwest of the historic deposit, while final rock assays from the fall prospecting program remain outstanding.

Key Details

• Geochemical Footprint Expansion: The 2025 soil geochemistry program expanded the favorable soil geochemistry footprint over a strike length in excess of 8.6 kilometers.
• Sample Collection: The program collected 2,998 B-horizon soil samples, including 86 field duplicate samples.
• New Anomaly Discovery: A newly discovered robust nickel-in-soil anomaly measuring 1,500 m by 400 m was identified approximately 2.7 km southwest of the Gochager Lake deposit.
• Geological Correlation: Mineralized variable-texture gabbro/container rock mapped over a strike of 3.5-plus km occurs within and coincident with the 8.6-plus km linear nickel-in-soil geochemical footprint.
• Interpretation: The 8.6-plus km geological/geochemical footprint is interpreted as a structural corridor/conduit suitable for the emplacement of multiple magmatic intrusions and associated Ni-Cu-Co mineralization.
• Drilling Context: Current drilling at the historic Gochager Lake deposit covers only a strike length of 240 meters, highlighting the significant exploration potential of the newly identified 8.6 km footprint.
• Program Interruption: Blank sections in the southwest corner of the 2025 program were not sampled due to an encroaching wildfire that truncated the field program.
• Geostatistical Thresholds (99th to 90th Percentile):
  • 99th percentile: >306 ppm Nickel (Ni) (50 samples)
  • 98th percentile: >201 ppm Ni (47 samples)
  • 95th percentile: >87.2 ppm Ni (144 samples)
  • 90th percentile: >48.2 ppm Ni (240 samples)
• QA/QC: Samples were analyzed by ALS Canada Ltd. using ultratrace ICP-MS (ME-MS41) after partial digestion (aqua regia). Internal QA/QC included 86 duplicate samples to monitor for contamination.
• Outstanding Data: Final rock assays from the fall prospecting program are still pending; further announcements will be made upon receipt and interpretation of these results.

Notable Quotes

• "One of our exploration goals at the Gochager Lake project has been to demonstrate potential scale and confirm our long-held belief that the historic Gochager Lake deposit is just one part of a highly prospective mineralized trend." — Ian Fraser, CEO and VP of Exploration
• "Our drilling to date at the historic Gochager Lake deposit only covers a strike length of 240 metres and we now have 8.6 kilometres of positive geochemical footprint to explore. These results are another step in validating the potential scale at the Gochager Lake project and our hypothesis that this trend has potential to host numerous additional magmatic Ni-Cu-Co sulphide deposits." — Ian Fraser, CEO and VP of Exploration
