Coast Copper Corp. announced that the Controlled Source Audio-frequency Magnetotellurics ground geophysical survey completed on its optioned, past-producing Empire Mine property located on Northern Vancouver Island, B.C. has generated three high-priority drill targets. In December 2023, Coast Copper engaged Peter E. Wallcott and Associates to complete a 5-line (totaling 5 line kilometers ("km")) CSAMT survey over portions of the Property near the historical Benson Lake Mine representing one of numerous targets on the Property.

Two drillholes were completed in this area in 2007 (MW07-48 & 49) by Grande Portage Resources Inc., with drillhole MW07-48 intercepting 7.5 m of a massive magnetite layer assaying 0.27 g/t Au, 0.45% Cu and 24.1% Iron ("Fe") and MW07-049 intercepting 6.7 m of a semi-massive sulphide and dike breccia assaying 0.25 g/t Au, 0.,64% Cu and 8.1% Fe 3. This resistivity low anomaly also appears to correlate with a historical "remaining mineable resource block" identified by Cominco Ltd. in December 1972 just prior to the mine being closed. One drillhole was completed in this area in 2007 ("MW07-51") that encountered skarn bands between 207-328 metres down the drillhole and a 2 m massive magnetite band even though it was drilled in a southerly direction and away from the target. In the first kilometer, very widely spaced and sometimes abandoned and technically directed drilling was completed in 2006 and 2007 (drillholes MW06-25,26 & 27 and MW 07-52,53 & 54) and although assay results were not as high-grade as most of the drilling at the Merry Widow Deposit, with the value of hindsight and a better understanding of the Old Sport Mineralized Horizon, they are very technically significant with some of the results highlighted below: MW06-25 returned an epidote skarn with pyrrhotite from 261-275 m with a one-meter interval of 1.46 g/t Au and 0.44% Cu, MW06-27 returning a 20 cm semi-massive pyrrhotite interval of 0.14% Cu, 484 parts per million Cobalt and 37.5% Fe which is even more significant considering the previous 5 m interval had no recovery, MW07-52 returning a 1.62 m intercept of massive magnetite of 0.54 g/t Au, 0.'52% Cu and 29.6% Fe, MW07-053 returning a 4.52 m intercept of 34.12% Fe and MW07-54 returning a 14.24 m intercept of 0.12 g/t Au and 0".

When these drillholes were completed to depth they also identified the transition to underlying Karmutsen volcanics and proved that the Old Sport Horizon continues for up to a kilometer south of the Benson Lake Mine. Based on the success of the CSAMT geophysical survey, further lines are proposed to generate new drill targets on the Property.
