ATCO MINING SIGNS DRILLING CONTRACT WITH BASE DIAMOND DRILLING LTD. TO DRILL ATLANTIC URANIUM PROJECT IN ATHABASCA BASIN

Atco Mining Inc. has signed a drilling contract with Base Diamond Drilling Ltd. to conduct drilling work at its newly optioned Atlantic uranium project in the Athabasca basin. An initial deposit has been paid and the Company will update its shareholders once drill rigs have been mobilized and the program begins.

About the Atlantic Uranium Project

The Atlantic Project consists of 7 mineral claims totaling 3,061 hectares. The Project is situated in the Mudjatik geological domain where several recent discoveries have been made, including IsoEnergy's Hurricane uranium deposit. The Project covers 6.5 km of an 18 km long, east-west trending conductive exploration trend which hosts numerous uranium occurrences. Standard Uranium completed a high-resolution ground gravity survey on the project in 2022, revealing multiple subsurface density anomalies, potentially representing significant hydrothermal alteration zones in the sandstone and proximal to basement conductors.

Historical drilling by Cameco in 1992 (Hole BE-04) encountered up to 0.06% U 3 O 8 over 0.5 metres in the sandstone, proximal to the unconformity. Follow-up drilling by Denison Mines in 2012 (Hole BL12-13), next to BE-04, encountered a metal-enriched fault-zone in the sandstone located 130 metres above the basement rocks that contains 10.2 ppm uranium, 786 ppm lead, and 2,270 ppm zinc over 0.1 metre. Additionally, a composite sample of the basal 13.4 metres of sandstone returned 477 ppm uranium. At the western claim block, drilling by Denison Mines in 2016 (Hole BL16-32) identified 342 ppm uranium over 0.5 metres at the base of the sandstone.

The scientific and technical information contained in this news release has been reviewed, verified, and approved by Neil McCallum, P.Geo, a director of Atco and a "qualified person" as defined in NI 43-101.
