TRANSATLANTIC MINING TO COMMENCE RESOURCE DRILLING AT HISTORIC MILLER GOLD MINE, MONTANA

Transatlantic Mining Corp. will commence resource definition drilling on its Miller gold mine project near Helena, Mont., United States.

Transatlantic has received its drill permit for the Miller mine and plans to drill downdip of the historic lower levels to over 100 metres of strike and depth on the principal vein structure. The ground conditions are envisaged to be good where the old workings have been open. Transatlantic plans to drill up to 3,000 metres this spring targeting the untested deeper zones.

Results from the assay laboratories are expected from six to eight weeks after the drill campaign and geological evaluation are completed.

Webinar: Transatlantic chief executive officer Bernie Sostak will host an interactive webinar discussing the company's drill program and future plans on Feb. 25, 2025, at 11 a.m. ET.

The Miller gold mine is located in Broadwater county, Montana, United States. The mine is approximately 29 miles northeast of Townsend, Mont., United States. The presence of gold mineralization has been confirmed by previous sampling in accessible areas of the mine. Transatlantic is earning into the historic Miller gold property by means of a gold production royalty.

A historical report on the Miller mine notes that gold-bearing ore was mined on a small scale by individual owners with sporadic production between 1901 and 1948. The mine is being reassessed by Transatlantic to review existing ground conditions and infrastructure.

Located at the top end of the Confederate gulch, near what is now a ghost town in Diamond City with a once population of 10,000 people, placer gold was abundant in this gulch.

Miller had an average historical recovered grade mined of 7.94 ounces per ton gold (248 grams per tonne gold) and 4.65 ounces per ton silver (145 grams per tonne silver).

Historical hole No. 1 was drilled 300 feet below the lowest recorded workings and recorded a grade of 14.7 ounces per ton gold (516 grams per tonne gold).

The Miller mine mineralization occurs in quartz veins within and on the contact of a quartz-diorite stockwork. The discrete veins dip 30 degrees to 50 degrees whilst the stockwork has multiple veinlets that range in width from a few centimetres to two metres. The contact zone of alteration has been noted as over 15 metres wide (50 feet). Mining has been undertaken on both open-cut and underground methodologies near surface. The mine areas is at an elevation of 2,000 metres (6,650 feet).

Highlights of previous sampling (see news release dated June 14, 2023) include:

• Miller mine -- lower level:
  • Opened up unsurveyed lower winze level immediately below the lower level;
  • First grab samples from lower winze level include 27.6 grams per tonne gold; visual gold has also been observed;
  • Extended lease agreement to first renewal term with option to purchase by production royalty.

Mr. Sostak said: "We are excited to be following up on the initial favourable rock sample program, historical high-grade drilling and production. The upcoming season of drilling and sampling will aid us in determining the continuity along strike and downdip efficiently."

About the Miller mine and claim group

Transatlantic has access to the upper and lower levels of the mine. The Miller mine is situated amongst patented and unpatented claims at an elevation of 1,920 metres (6,400 feet) and accessible by roads 50 miles from Helena, Mont., United States. Should mining occur at any time, an 8.5-per-cent royalty on ounces is to be paid. During the term of the agreement, the company may purchase the property for $4.5-million, less the royalty payments made above, with a perpetual 1-per-cent net smelter return royalty 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 electrum and pyrite often observed amongst the four known adits located on the property.

Quality assurance/quality control and core sampling protocols

The rock-chip samples are grabs from the winze-level drive of five kilograms in weight. The samples were crushed in whole to plus 70 per cent passing two millimetres and then split and pulverized with analysis for gold and silver at the Christofferson laboratory in Smelterville, Idaho, United States. The laboratory is an independent assay and umpire laboratory that follows industry techniques. The samples, after being pulverized, are analyzed with a 15-gram-to-30-gram fire assay charge and gravimetrically finished.
