Vancouver, British Columbia–(Newsfile Corp. – August 27, 2025) – Transatlantic Mining Corp.\u00a0<\/b>(TSXV: TCO)\u00a0(the “Company”) is pleased to provide an update on drilling at the historic Miller Mine in Montana, USA.<\/p>\n
On December 21,\u00a02020 Transatlantic exercised its initial option term to acquire 100% of the Miller Mine located in the Broadwater County in the State of Montana , USA. These claims are approximately 29 miles to the northeast of Townsend in Montana USA with gold mineralization that has been verified on the old levels of the historic Miller mine predominantly mined between 1900 and the 1940’s.<\/p>\n
Transatlantic is drilling down dip of the historic lower levels to over 100 metres of strike and depth on the principal vein structure as well as exploration along strike north and south. Transatlantic has completed 2,069 metres (m) in 25 holes of a 3,000 m planned program in phase 1 campaign.<\/p>\n
The hole depth range is from 10 m to 207 m. Phase 1 comprises of a total of 25 holes. (Hole # 14: Figure 2). Of the 25 holes completed, 8 have been drilled deeper under the existing workings in the upper target area (Figure 1), 10 have explored extension to the north and south and 7 shallow holes have tested an old mine dump. The main target and focus is the vein\/s on the contact of the sediment and granodiorite. <\/p>\n
Samples from the first 17 holes have recently been submitted to the Laboratory with assays and results projected to be completed end of August early September.<\/p>\n
In concert with the surface drilling phase 1, we are now mobilising an underground drill rig today for testing the lower target area (Figure 1).<\/p>\n
The target is being well intersected on the sediment granodiorite contact to date,” said Transatlantic CEO Bernie Sostak. “We are getting near the end of the phase 1 drilling campaign, and are looking forward to sharing the results with investors.”<\/i><\/p>\n

The mine is approximately 29 miles northeast of Townsend in Montana USA. The presence of gold mineralization has been confirmed by previous sampling in areas of the mine where access is possible. Transatlantic is earning into the historic Miller Gold Property by means of a gold production royalty near Helena, Montana.<\/p>\n A historical Report (*) on the Miller Mine notes that historically, gold bearing ore was mined on a small scale by individual owners with sporadic production between 1901 and 1948. The mine is being re accessed by Transatlantic to review existing ground conditions and infrastructure for ongoing rehabilitation.<\/p>\n Located at the top end of the Confederate Gulch near what is now a ghost town in Diamond City, of which once had a population of + 10,000. Placer gold was abundant and rich in this Gulch.<\/p>\n The Miller Mine mineralization occurs in quartz veins within and on the contact of a quartz granodiorite stockwork. The discrete veins dip between 30 and 80 degrees whilst the stockwork has multiple veinlets that range in width from a few cms to 2 metres. The contact zone of alteration has been noted as over 15 m wide ( 50 feet ). Mining has been undertaken on both an open cut and underground methodology. The mine is at an elevation of 2000 m ( 6650 feet)<\/p>\n Highlights of previous sampling ( see news release dated June 14, 2023)<\/i><\/p>\n Miller Mine – Lower Level <\/b><\/p>\n About the Miller Mine and Claim Group:<\/b><\/p>\n Transatlantic has access to the Upper and Lower Level of the mine. The Miller Mine is situated amongst patented and unpatented claims at an elevation of 1920 m (6,400 feet) and accessible by roads 50 miles from Helena, Montana USA. Should mining occur at any time, an 8.5% royalty on ounces is to be paid. During the term of the agreement, the Company may purchase the property for US $4,500,000, less the royalty payments made above, with a perpetual 1% NSR to the vendor thereafter.<\/p>\n The gold and silver mineralization generally occurs on the contacts of sediments and igneous intrusive with native gold and sulphides including pyrite often observed amongst the 4 known adits located on the property.<\/p>\n Qualified Person and NI 43-101 Disclosure<\/b><\/p>\n Aslam Awan PhD MAusIMM (CP Geo) is the Qualified Person pursuant to National Instrument 43-101 for having reviewed, only the technical information contained in this news release.

The samples were crushed in whole to plus 70 % passing 2 mm and then split and pulverised with analysis for gold and silver at the Christofferson Laboratory, Smelterville, Idaho USA. The Laboratory is an independent assay and umpire laboratory that follows industry techniques. The samples after being pulverised are analysed with a 15 to 30 gram fire assay charge and gravimetrically finished.<\/p>\n (*) Hemsworth FJ: Report on the Miller Mine Helena Montana ( July 2 1969)<\/i><\/p>\n (**) Company News Release dated June 14, 2023<\/i><\/p>\n About Transatlantic Mining Corp.<\/b><\/p>\n Transatlantic Mining\u00a0(TSXV: TCO)\u00a0is an emerging precious and base metal explorer.
