/NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES./

TSX.V: COCO

VANCOUVER, May 16, 2024 - Coast Copper Corp. ("Coast Copper" or the "Company") (TSXV: COCO) is pleased to announce it has closed its previously announced non-brokered private placement (see news release dated May 8, 2024), issuing 8,750,000 units ("Units") at an issue price of $0.06 per Unit for gross proceeds of $525,000 (the "Offering").

Each Unit will consist of one common share of Coast Copper and one non-transferable common share purchase warrant, with each warrant entitling the holder to acquire an additional common share of the Company at an exercise price of $0.12 per share with an expiry date ("Expiry Date") of 36 months from completion of the Offering (the "Closing Date").

Coast Copper would like to highlight that as a result of the Company selling its 100% interest in the Gin, Bonanza and Eldorado properties (collectively, the "Red Chris Properties") to Skeena Resources Ltd. ("Skeena") in October 2022 for an aggregate purchase price of $3,000,000 in cash and shares, this is the first financing the Company has undertaken since September 2022. The Company has been able to move its projects forward systematically and at low cost with minimal dilution over the last 18 months and is positioning itself for a market recovery. The Company will continue to receive the final $1,000,000 in cash and shares from Skeena over the next 12 months.

Tim Thiessen, Coast Copper CFO comments: "As many of our owners and stakeholders are already aware, we have been extremely prudent with the proceeds from our Red Chris Properties sale to Skeena in 2022. We still have over 40,000 common shares of Skeena on hand plus another $1,000,000 in receivables pursuant to the sale. The overall market appears to be on the cusp of revaluing copper-focused assets like our Empire Mine property which includes Benson Mine, a former producing copper mine operated by Cominco from 1968 to 1972, which returned head grades averaging 1.9% copper and 1.8 grams per tonne gold (in 1,196,117 tonnes) in massive sulphide zones up to 30 metres thick ¹ ². Insiders and close associates with a long-term outlook now hold approximately 47.3% of the Company on an undiluted basis and we are excited to continue creating value for our shareholders."

Two directors and one officer of the Company (the "Insiders") participated in the Offering for an aggregate of 1,800,000 Units, representing 20.6% of the Offering. The participation by the Insiders in the Offering is considered to be a related-party transaction as defined under Multilateral Instrument 61-101 ("MI 61-101"). The transaction is exempt from the formal valuation and minority shareholder approval requirements of MI 61-101, as neither the fair market value of the securities being issued nor the consideration being paid exceeds 25% of the Company's market capitalization.

Following the Offering, the Company's CEO Adam Travis will own or control, directly and indirectly, securities representing 9,009,833 common shares of the Company on an undiluted basis, and 13,453,166 on a partially diluted basis, representing approximately 12.25% and 17.25% of the Company's issued and outstanding shares, respectively. As required for the purposes of National Instrument ("NI") 62-103, Mr. Travis has filed an early warning report ("EWR"), completed filings on SEDI and the Company has issued this news release to announce that he has increased his position by more than 2%, on a partially diluted basis, since the filing of his last EWR on September 28, 2022. Mr. Travis acquired these shares for the purposes of an investment and depending on market and other conditions, Mr. Travis may from time to time in the future increase or decrease his ownership, control or direction over securities of the Company, through market transactions, private agreements, or otherwise.

In satisfaction of the requirements of TSX-V Policy 4.1 - Private Placements, TSX-V Policy 5.9 - Protection of Minority Securityholders in Special Transactions, MI 61-101 - Protection of Minority Security Holders in Special Transactions, NI 51-102 - Continuous Disclosure Obligations, NI 62-104 - Take-Over Bids and Issuer Bids, and NI 62-103 - The Early Warning System and Related Take-Over Bid and Insider Reporting Issues, a material change report respecting the acquisition of securities by the related party transactions and an early warning report respecting Mr. Travis' increased holdings of the Company's capital structure will be filed under the Company's SEDAR Profile at www.sedarplus.com.

As noted in its news release dated May 8, 2024, the net proceeds raised from the issuance of the Units will be used:

• to make the final payment due September 2024 in relation to the Company's optioned Empire Mine property mineral claims;
• to conduct field work on the newly acquired Sully property located adjacent to the PJX Resources Inc.'s Dewdney Trail property³ (see news release dated February 12, 2024);
• to continue Coast Copper's strategic mineral property acquisition program; and
• for working capital and general corporate purposes.

Finders acting in connection with the Offering received aggregate cash fees of $8,820 and a total of 147,000 finders' warrants, with the warrants having the same terms as those in the Offering.

The Offering remains subject to customary closing conditions including the approval of the TSX Venture Exchange. All securities issued in the Offering will be subject to a statutory hold period of four months and a day from the Closing Date.

This news release does not constitute an offer to sell or a solicitation of an offer to sell any of the securities in the United States. The securities have not been and will not be registered under the United States Securities Act of 1933, as amended (the "U.S. Securities Act") or any state securities laws and may not be offered or sold within the United States or to U.S. Persons unless registered under the U.S. Securities Act and applicable state securities laws or an exemption from such registration is available.
