ATCO MINING'S GRAVITY SURVEY SUPPORTS PRESENCE OF THREE LARGE SALT DOME TARGETS

Atco Mining Inc. has received preliminary data from the airborne gravity survey recently conducted on its 100-per-cent-owned salt projects, located within the St. George's Bay basin in southwestern Newfoundland.

The preliminary data and interpretation reveal that three high-priority oval-shaped gravity anomaly targets are present on the company's tenures. The geometry of the gravity-low features suggests the presence of underground salt dome structures. Additional interpretation will be performed upon receipt of the final survey data from the contractor and will be provided in an additional news release.

Neil McCallum, director of Atco Mining, states: "I am very encouraged by the data that I have seen thus far from the survey. It confirms our geological exploration model of the presence of salt dome structures on our project and I am looking forward to showcasing our final results to our shareholders upon receipt. Having the survey confirm three large high-priority targets at this early stage is much better than we could have hoped for."

The geophysical program was completed approximately three weeks ago (see news release dated Jan. 25, 2023) utilizing the Falcon Plus airborne gravity gradiometer (AGG) and magnetics completed by Xcalibur Multiphysics of Mississauga, Ont. Falcon is the world's only purpose-built AGG system, designed to isolate aircraft motion noise. The survey was managed and will be interpreted by GroundTruth Exploration of Dawson City, Yukon.
