Coast Copper Provides Update on Scottie West property and Jeff Kyba Joins as Technical Advisor

VANCOUVER, March 6, 2023 - Coast Copper Corp. ("Coast Copper" or the "Company") (TSXV: COCO) is pleased to provide an update on its 100% owned Scottie West property (the "Property") located in British Columbia's ("B.C.") Golden Triangle district approximately 35 kilometers ("km") northwest of Stewart, B.C. and immediately west of Scottie Resources Corp.'s Scottie Gold Mine project¹ (see Figure 1). The Company also wishes to announce that Jeff Kyba has joined as a technical advisor.

The Property was acquired by staking in May 2020 for $11,128 and optioned to Europacific Metals Inc. ("EuroPacific") (formerly known as Goldplay Mining Inc.) on November 23, 2020. As announced November 21, 2022, the Property was returned to the Company as a result of EuroPacific moving its exploration focus to projects in Portugal after spending more than $330,000 in exploration expenditures, making cash payments of $50,000 to Coast Copper and issuing $75,000 worth of shares to Coast Copper in regards to the Property option. EuroPacific completed surface exploration programs as well as completed a National Instrument 43-101 technical report. The conclusion of the 2021 report noted that the surface program identified numerous mineralized showings with at least 13 zones of gold-bearing quartz-carbonate sulphide (pyrite ± arsenopyrite ± pyrrhotite ± chalcopyrite ± galena ± sphalerite) veining occurring on the Property. These veins host sulphide-rich shoots with highly anomalous gold values and are hosted in a package of andesitic volcanics from the Unuk River Member of the Betty Creek Formation situated adjacent to the contact with the Summit Lake stock, part of the early Jurassic aged Texas Creek Plutonic Suite. This style of mineralization is characteristic of intrusion-related mesothermal veins. The Property occurs along the southwest extension of the apparent mineralized belt that includes Scottie Resources' Blueberry Zone, the Scottie Gold Mine and the recently discovered Domino Zone ¹. Highlights from EuroPacific's 2021 sampling include²:

• Rock sample assaying: 5.90 grams per tonne ("g/t") gold ("Au") and 155 g/t silver ("Ag") on the SE Exposure.
• Rock sample assaying: 5.29 g/t Au on the Leduc NE Ridge.
• Rock sample assaying: 2.19 g/t Au and 119 g/t Ag on the Leduc East Central Ridge.
• Rock sample assaying: 0.95 g/t Au, 91.87 g/t Ag, and 2.77% zinc on the East Border Nunatak.

Adam Travis, Coast Copper's CEO comments: "Upon receiving the property back from EuroPacific, we conducted a review of their work in the context of new discoveries and the work being completed on the adjacent Scottie Resources property. We were excited to see gold in rock samples up to 5.29 g/t which were reported from veins and structures. Some of these appear to be associated with structural and magnetic trends consistent with what has been observed on the Scottie Resources property. I've admired Jeff Kyba's work over the last decade, in both government role and industry, particularly in the Golden Triangle where 'Kyba's Red Line' has been an important exploration guide. Jeff joining Coast Copper as a technical advisor speaks volumes about the caliber of our projects and our team. Although Scottie West is not our principal project, and we remain focused on the Empire Mine property, we are very excited to get out on the ground with Jeff and make additional discoveries."

Mr. Kyba's experience spans grassroots exploration to deposit delineation for precious and base metals as well as five years of regional oversight of all exploration and mining projects in northwestern B.C. for the provincial government. During his 5+ year tenure as Regional Geologist, he completed extensive site visits and field work investigating the variety of mineral deposits throughout the region. This work resulted in several government publications and a map identifying favorable areas to explore for minerals, commonly known as the 'Kyba Red Line'; a stratigraphic unconformity located within 2 km of nearly all major deposits in the Stikine Terrane. His map remains in use today.

Jeff Kyba comments: "The Coast Copper team and projects are an inspiring combination. Scottie West is an exciting discovery in an area with a highly prospective geological address and long-lived exploration history. Adam and his team have yet again demonstrated there are more discoveries to be made and I'm looking forward to working with them."

Coast Copper has granted Mr. Kyba a total of 100,000 stock options of the Company pursuant to the Company's 20% fixed Long-Term Incentive Plan, subject to TSX Venture Exchange approval. Each stock option is exercisable into one common share of the Company, subject to certain vesting requirements at an exercise price of $0.07 per share with an expiry of March 3, 2028.
