Transatlantic Intercepts up to 6.0 g/t Au and 13.71 g/t Ag over 1.5 Meters at the Historic Miller Gold Mine, Montana

The news release dated January 23, 2026, provides assay results from the completed 2,070-meter, 25-hole Phase 1 reverse circulation drill program at the historic Miller Gold Mine in Montana. The drilling intersected the targeted sediment/granodiorite contact, returning 22 intercepts ranging from 1.03 g/t Au to 6.00 g/t Au over widths of 1.5 meters. The highlight was 6.00 g/t Au over 1.5 meters in hole MMRC2514. Eleven holes returned no significant intercepts. The CEO stated the program confirmed the contact along strike and down dip, with the deposit remaining open. The release also provided operational updates: the planned "Lower Target" underground drilling at Miller is postponed to 2026 due to an expiring permit (extension applied for); drilling at the Golden Jubilee project is postponed due to winter weather (permit extension sought); and the company is awaiting results from a muon tomography trial at the Monitor project's Anvil prospect. A webinar to discuss the results was scheduled for January 26, 2026.

The news is materially positive as it delivers the first batch of assay results from the long-anticipated maiden drill program at the flagship Miller project, confirming the presence of gold mineralization at the targeted geological contact. The grades (1-6 g/t Au) are generally in line with historical high-grade production (historical average ~7.94 oz/t or ~272 g/t, but over much narrower widths). However, the impact is tempered by several factors: the intercepts are narrow (predominantly 1.5m), the true width is unknown, and a significant portion of the holes (11 out of 25) returned no significant results. The concurrent announcement of permit-related delays for follow-up work at Miller and Golden Jubilee introduces near-term operational uncertainty. The market had likely priced in some positive results given the stock's rise from ~$0.10 in early January to $0.14 ahead of the news. The results are confirmatory but do not indicate a major, high-grade, bulk-tonnage discovery that would be a game-changer for the company's valuation.

Transatlantic Mining Corp. is a Canadian junior exploration company listed on the TSXV (TCO). Its primary assets are three exploration-stage projects in the USA: 1. Miller Gold Mine (Montana): The current flagship, a historic high-grade gold mine. The company is earning a 100% interest through a production royalty agreement, with an option to purchase for $4.5M (less royalties paid), after which a 1% NSR remains. 2. Monitor Copper-Gold Project (Idaho/Montana): An 80%-owned copper-gold-silver project with established Exploration Targets. Strategy focuses on cost-effective underground access for evaluation. 3. Golden Jubilee Project (Montana): A gold exploration property with high-grade drill intercepts from a previous program.
