Coast Copper to sell Borealis to Hi-View

Mr. Adam Travis reports COAST COPPER SELLS ONE OF ITS THREE TOODOGGONE PROPERTIES FOR $1.375 MILLION IN COMBINED CASH AND SHARES Coast Copper Corp. entered into an asset purchase agreement on Aug. 27, 2025, with Hi-View Resources Inc., which will acquire a 100-per-cent interest in Coast Copper's Borealis property located in the Toodoggone district in north-central British Columbia. In consideration, Hi-View will pay Coast Copper $500,000 in cash, issue 3.5 million Hi-View common shares to Coast Copper at a deemed price of 25 cents per consideration share and grant Coast Copper a bonus payment under certain conditions, as more fully described below. Coast Copper will also retain a 3-per-cent net smelter return royalty subject to buyout provisions as outlined below. Adam Travis, chief executive officer, commented: "With the recent Aurora discovery made by Amarc Resources Ltd. and Freeport-McMoRan Mineral Properties Canada Inc., the Toodoggone district has become one of the hottest exploration regions in Canada. The sale of one of our Toodoggone properties to Hi-View validates our strategy of acquiring underappreciated exploration properties throughout B.C. while we advance our core projects. Borealis is highly prospective for porphyry copper-gold, polymetallic and skarn targets, and we are extremely excited to be able to participate in the upside of the district by becoming the largest shareholder of Hi-View as well as retaining a NSR royalty and potentially receiving a transaction bonus. We are committed to completing the first phase of exploration in September, which will include an airborne magnetic survey and further compilation, such that Hi-View will be in a position to quickly move towards ground geophysical surveys to expand and better define historical induced polarization geophysical anomalies prior to drill testing." The property covers 9,106 hectares and is over 25 kilometres in length, located immediately west and adjacent to Amarc's Joy property and Centerra Gold Inc.'s Kemess mine. For more details on this property, as well as the two others in the district that Coast Copper continues to hold, please see the news release dated April 8, 2025. Coast Copper's chair of the board, Dr. Fletcher Morgan, is the chief executive officer of TDG Gold Corp., a company that has other interests in the Toodoggone district, and, as a result, recused himself from voting on this transaction, which received unanimous support from the rest of the Coast Copper board. Tim Thiessen, chief financial officer, commented: "Selling our Red Chris properties in 2022 provided the company with sufficient working capital such that we have not needed to raise any significant funds since then while, at the same time, continuing to advance our core projects and acquire new ones. Adam Travis has a remarkable ability to locate, review and acquire prospective properties in strategic locations. The Hi-View transaction, with a value of over $1-million, will further assist Coast Copper in maintaining our working capital without diluting shareholders. We look forward to the future success of Hi-View as it advances exploration at the Borealis property." Agreement terms Under the terms of the agreement, Hi-View will: Immediately pay Coast Copper a non-refundable deposit of $50,000, which will be spent on exploration expenditures on the property to keep it in good standing for a period of 12 months; Upon closing of the transaction, make a cash payment of $450,000 to Coast Copper; Upon closing of the transaction, issue to Coast Copper 3.5 million common shares of Hi-View; the first 1.05 million consideration shares will become free trading four months after the completion of the transaction, and the remaining consideration shares will become free trading in equal amounts of 350,000 consideration shares at the end of each following month, such that the final 350,000 consideration shares will become free trading 11 months after the completion of the transaction. Coast Copper will retain a 3-per-cent net smelter return royalty on the property, of which Hi-View will have to right to repurchase 1 per cent for $2.5-million and an additional 1 per cent for $5-million. Transaction bonus If, after the closing date, Hi-View completes a sale transaction, defined as a transaction resulting in a direct or indirect sale or transfer of property or a takeover, amalgamation, plan of arrangement or business combination in respect of Hi-View, the result of which 51 per cent or more of the issued and outstanding equity or voting interests of Hi-View is acquired by a single arm's-length third party, and provided that immediately before the consummation of such sale transaction, either: (a) Hi-View, or an affiliate thereof, continues to own an interest in the property; or (b) Hi-View, or an affiliate thereof, has disposed of an interest in the property in a transaction connected or related to the sale transaction, Hi-View agrees to pay to Coast Copper, within five business days following the completion of the sale transaction, a one-time bonus payment in accordance with the following scale: If the transaction is less than $10 million, the bonus payment would be $500,000, if $10-million to $20-million, the bonus payment would be $1-million and, if greater than $20-million, the bonus payment would be $1.5-million.
