Coast Copper Corp. announced that since completion of its drill program in 2022 on the optioned Empire Mine property (the "Property"), focus has been on utilizing all recent and historical data available to develop a new geological model that incorporates the structural and lithological controls observed on surface, underground and in drill core. The company new model highlights the potential down dip continuation of near surface, stacked thrust horizons that are associated with copper-gold-iron mineralization observed at the historical Merry Widow Pit approximately 1 kilometer ("km") east northeast to the Benson Lake Mine.

Surface geological observations and mapping, ore mineral occurrences, underground workings and drillhole data also indicate that these thrust horizons and associated mineralization occur along strike over a 5 km northerly trend. Recently completed field work, led by Dr. Jim Oliver, identified the significance of regional scale planar features to the current resource block, and to other mineral occurrences across the Property. The new model highlights the potential for significant copper-gold-iron mineralization to continue adjacent to, and up to 500 metres ("m") in elevation below the Merry Widow Pit mineralization, as well as continuing along the trend of these regional features and down dip towards Benson Lake Mine.
