COAST COPPER CEO INCREASES OWNERSHIP POSITION TO 19.42 PER CENT

Coast Copper Corp. has been filed by Adam Travis, chief executive officer and a director of the company. Since his last EWR (early warning report) which was filed on May 16, 2024, Mr. Travis has indirectly acquired, through Cazador Resources Ltd., a private company controlled by him, an additional 1,455,500 common shares of the company and has received an additional 600,000 incentive stock options. These transactions have increased his share ownership in the company's current issued and outstanding shares by 2.17 per cent on a partially diluted basis.

Prior to the transactions, Cazador held 9,009,833 common shares of the company, 2,643,333 share purchase warrants and 1.8 million incentive stock options. This represented 17.25 per cent of the company's issued and outstanding shares on a partially diluted basis. Mr. Travis now controls 10,465,333 common shares of the company, 2,643,333 share purchase warrants and 2.4 million incentive stock options, which represents 19.42 per cent of the company's current issued and outstanding shares on a partially diluted basis.

Adam Travis, chief executive officer, comments: "Coast's focus in 2025 was to expand our generative pipeline and complete baseline studies for a discovery-focused 2026. Our portfolio now includes mineral tenures covering high-grade silver, copper, gold and rare earths, all located within some of the best mining districts in B.C. In parallel, we increased our treasury through the vending of a non-core Toodoggone property and had no dilutive capital raising events during 2025. On behalf of Coast's management team and board, we'd like to thank all our shareholders for their loyalty and support in 2025. With the backdrop of the prices of key minerals in the Coast project portfolio at or near all-time highs, we look forward to continuing to advance our execution strategy in 2026. That's also why I continue to be a buyer of Coast shares."

The securities were acquired for investment purposes. Mr. Travis has a long-term view of the investment and may, in the future, acquire and/or dispose of securities through the open market, through private transactions or through the company's long-term incentive plan as circumstances or market conditions may warrant.

In total, the directors and officers ownership percentage is 40.42 per cent of the company's current issued and outstanding shares on a partially diluted basis.
