Transatlantic Provides Update on Drilling at the Historic Miller Gold Mine, Montana
MWN-AI** Summary
Transatlantic Mining Corp. (TSXV: TCO) has announced that it is progressing with its drilling campaign at the historic Miller Gold Mine in Broadwater County, Montana. The company, which acquired 100% of the mine in December 2020, aims to further explore the gold mineralization previously identified at the site, which was actively mined from the early 1900s until the late 1940s.
As part of its phase 1 drilling program, Transatlantic has completed 2,069 meters across 25 holes of a planned 3,000 meters. The drilling focuses on the principal vein structures, with particular attention to areas extending north and south of the mine and assessments beneath the existing workings. The drilling depth ranges between 10 meters to over 200 meters. Samples from the first 17 holes have been sent to the laboratory, with results expected by the end of August or early September.
In addition to surface drilling, Transatlantic is mobilizing an underground drill rig to test lower target areas. CEO Bernie Sostak has expressed optimism about the drilling results, noting that the targeted veins are being well intersected on the contact between sediment and granodiorite.
Historically, the Miller Mine reported an average recovered gold grade of 7.94 ounces per ton, with previous high-grade samples indicating potential for substantial mineralization. The site is situated to the northeast of Townsend, Montana, accessible by roads, making it a prime candidate for future mining operations.
Transatlantic Mining remains committed to evaluating and rehabilitating the mine's infrastructure, with an extended lease and royalty purchase agreement in place. The company is positioned not only to explore this historical site but also to capitalize on the opportunities it presents within a stable mining jurisdiction.
MWN-AI** Analysis
Transatlantic Mining Corp. (TSXV: TCO) has recently provided updates on its drilling activities at the historic Miller Gold Mine in Montana, which could significantly influence its market performance. As the company approaches the conclusion of its Phase 1 drilling campaign, investors should consider several key factors.
The Miller Mine, known for its high historical grades of gold (averaging 7.94 oz/ton) and recently notable rock chip samples (up to 27.6 g/t), demonstrates potential for economically viable mineral extraction. The ongoing drilling program, which has covered 2,069 meters across 25 holes, targets extensive vein structures known for their gold-bearing potential. Notably, preliminary assays from these holes will bolster investor sentiment when released in early September.
The strategic expansion of drilling into both deeper and lateral zones emphasizes the management's confidence in the mine's geology and potential recoverable resources. The decision to mobilize an underground drill rig indicates a commitment to further exploratory success, which may yield significant findings that can drive higher valuations.
As the market reacts to the upcoming assay results, potential catalysts may include favorable drill results, increased investor interest in precious metals due to economic uncertainties, and the company’s demonstrated ability to responsibly develop mining assets in a stable jurisdiction. However, mining operations come with inherent risks including fluctuations in commodity prices, regulatory changes, and operational challenges.
Investors should keep a close eye on TCO’s stock performance following assay results, and consider exposure to precious metals as a hedge against inflation and economic volatility. Current trading levels may present an entry opportunity; however, due diligence and risk assessment are paramount before making any investment decisions in this evolving resource sector.

Vancouver, British Columbia--(Newsfile Corp. - August 27, 2025) - Transatlantic Mining Corp. (TSXV: TCO) (the "Company") is pleased to provide an update on drilling at the historic Miller Mine in Montana, USA.
On December 21, 2020 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.
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.
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.
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.
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).
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."

The Miller Gold Mine is located in the Broadwater County in the State of Montana, USA. 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.
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.
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.
- Miller had an average recovered mine grade of 7.94 Oz /ton Au (248 g/t Au ) and 4.65 Oz /ton Ag ( 145 g/t Ag)(*)
- Hole #1 was drilled 300 feet below the lowest recorded workings and recorded 14.7 Oz /ton Au (516 g/t Au)
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)
Highlights of previous sampling ( see news release dated June 14, 2023)
Miller Mine - Lower Level
- Opened up Lower Winze Level immediately below the Lower Level.
- First grab samples from Lower Level Winze include 27. 6 g/t Au(**), visual gold has also been observed.
- Extended Lease Agreement to first renewal term with option to purchase by production royalty.
About the Miller Mine and Claim Group:
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.
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.
