Transatlantic extends Golden Jubilee exploration permit

Executive Summary

• Transatlantic Mining Corp. has received an extension and approval from the U.S. Department of Agriculture for the plan of operation at its Golden Jubilee gold project in Montana, valid until December 31, 2026.
• The extension allows the company to resume drilling and dewatering operations, which were previously postponed due to winter weather conditions and the expiration of an interim permit on December 1, 2025.
• The upcoming 2026 exploration program is designed to test the downdip extension and plunge of the main mineralization zone, as well as a new geophysical offset target, with plans to drill up to 1,000 meters in two to four holes.

Key Details

• Permit Extension: The U.S. Department of Agriculture approved the plan of operation for the Golden Jubilee project, extending the approval period to December 31, 2026.
• Previous Delays: Drilling previously disclosed on September 8, 2025, was postponed due to winter weather; drill contractors could not mobilize before the interim permit terminated on December 1, 2025.
• 2026 Program Scope:
  • Test the downdip extension and plunge of the main zone of mineralization.
  • Test a geophysical offset target that has not been drilled previously.
  • Dewater the mine and survey it for further exploration potential.
  • Planned drilling volume: Up to 1,000 meters in two to four holes.
  • Target depth: Moderately shallow depths of 300 meters.
• Strategic Impact: CEO Bernie Sostak notes that testing the geophysical offset could more than double the known strike length and potentially double the gold-bearing potential and future endowment.
• Historical Drill Results (April 13, 2023 Program):
  • Hole 2201: 9.1 meters at 7.8 g/t Au from 64 m depth (8.0 m true width), including 1.5 m at 16.11 g/t Au; and 6.1 m at 6.86 g/t Au from 86.9 m depth (5.5 m true width).
  • Hole 2203: 6.1 m at 13.1 g/t Au from 111.3 m depth (6.0 m true width), including 3.0 m at 17.3 g/t Au.
• Project Location: 22 claims in Granite County, Montana, situated at an elevation of approximately 2,350 m on the regional Red Lion vein line trend.

Notable Quotes

• "After the last successful program in 2023, we're excited to test further the downdip and plunge of this main zone of high-grade gold mineralization," said Bernie Sostak, chief executive officer of Transatlantic. "There is also the potential to test the geophysical offset as a discovery, which would more than double the length of known strike, as well as any parallel mineralized zones at Golden Jubilee. This could have significant impact on the overall gold-bearing potential and future gold endowment."
