Vancouver, British Columbia - TheNewswire - July 13, 2023 - Atco Mining Inc. (the “Company” or “Atco”) (CSE:ATCM) (OTC:ATMGF) (Frankfurt:QP9) is pleased to announce the results of the final interpretation by GroundTruth Exploration on its 100%-owned Flat Bay salt project, located within the St. George’s Bay Basin in southwestern Newfoundland, which confirm that the gravity-low is centered on the Company’s tenures.

The detailed interpretation includes inversion modelling to attain a 3D view of the gravity anomaly at depth.  The relatively low density of salt with respect to surrounding rock types makes the survey an ideal exploration method.  The results of the interpretation reveal a high-priority gravity-low anomaly that is consistent with the interpretation of a salt-dome structure at the Company’s tenures.  The 3D interpretation of the model suggests that the salt dome structure may be present at a depth of approximately 1,000 metres below surface and extending as deep as the model predicts (approximately 1500 metres below surface).  This depth estimate is consistent with historical drilling of hole “ST-1” located on the Flat Bay Tenures, which only reached a depth of 411.5 metres below surface, and the salt-bearing Codroy Group was estimated to be at a depth of approximately 1,100 metres based on stratigraphical relationships.

“The recent interpretation of the modern historical data supports our view that the Flat Bay target has the characteristics to host a salt dome of significant scale” states Neil McCallum, director of Atco Mining, “we will continue to integrate this information with other available datasets, such as the seismic surveying completed in 2005.”
