Coast Copper Corp. has identified four exploration targets each with the potential to expand Coast Copper's recently announced National Instrument ("NI") 43-101 Mineral Resource Estimate (the "2023MRE") for the gold-copper Merry Widow open pit located at its optioned Empire Mine property ("Empire Mine "or the "Property") on northern Vancouver Island, B.C. The 2023 MRE for the Merry Widow open pit hosts an inferred resource of 81,322 ounces ("oz") gold equivalent ("AuEq") grading 3.52 grams per tonne ("g/t") gold ("Au") and 0.50% copper ("Cu") within 0.59 million metric tonnes Mt), using a net smelter return ("NSR") cut-off of $30 CDN1 The 2023 MRE covers a 170-meter ("m") strike length to a depth of 130 m below surface. The Merry Widow resource is open along strike and down-dip based on a review of the updated geological model, historical data review and the 2023 MRE.

This updated information shows the potential to grow the resource footprint (in what has been defined as the " upper zone"). The four drill target areas that could potentially expand the 2023 MRE are: Along strike to the north-northeast ("NNE") for at least 150 m to the Raven Bluff zone, To the south for at least 200 m to the Marten zone, At depth for at least 70 m based on geological mapping and sampling from the Kingfisher underground, as well as the geological observations noted while historically mining magnetite in the 1960s, and the footwall of the magnetite bodies as noted in 1989 drillholes and observed along the footwall of the current pit.
