COAST COPPER HIGHLIGHTS ITS ANYOX AREA PROJECTS AND CONGRATULATES BOTH TDG AND GOLIATH

Coast Copper Corp. has highlighted its mineral claim holdings in the Anyox area of northwestern British Columbia based on recent activity in the area by TDG Gold Corp. and Goliath Resources Ltd. Coast Copper first started acquiring its Anyox mineral claims in October, 2024. Coast Copper congratulates TDG on its recent discovery of the new 4300 zone volcanogenic massive sulphide (VMS) lens, which sits below the former-producing Hidden Creek mine at TDG's Anyox project and which it acquired in July, 2025. The company also wishes to congratulate Goliath, which has been reporting numerous high-grade gold intercepts from its Surebet discovery approximately 20 kilometres to the north of Anyox. Coast Copper holds some of the only mineral claims adjacent and internal to the Goliath ground.

Adam Travis, chief executive officer, commented: "Leveraging our hundreds of years of combined experience in B.C., we have been strategically acquiring key land positions over the last few years, mostly through staking in at least seven active mining camps, including in the Anyox area, to capitalize on the millions of dollars in exploration being spent by our neighbours. This is one aspect of our three-pronged approach, whereby we: (1) continue to advance our flagship Copper Kettle and Empire mine projects; (2) gain exposure to silver (Sweeney and Virginia silver properties) and rare critical elements (Rock Canyon South and Rock Candy North properties); and (3) monetize our other non-core properties and utilize the funds to advance our key projects in the least dilutive manner possible to existing shareholders, of which insiders hold a very significant portion."

Anyox area mineral claim holdings

The company holds two main blocks of claims in the Anyox area, consisting of the Anyox East Islands (approximately 2,002 hectares) and the Bonanza South (404 hectares) properties. The Anyox East (Islands) property was acquired in October, 2024, over the Jurassic sediments that overlie the volcanic contact and site of VMS mineralization. Limited historical work, including some airborne geophysical anomalies and structural zones with associated intrusive dikes, warrants follow-up. The Bonanza South property was acquired in February, 2025, and covers the favourable contact between volcanics and sediments that hosts mineralization in the Anyox camp as noted as a potential VMS trend highlighted by TDG Gold.

Golddigger area claim holdings

The David property (approximately 1,408 hectares) is a thin (one kilometre by seven kilometres east-west and seven kilometres north-south) strip adjacent and internal to Goliath's Golddigger property. In 1990, a small sampling program (three rock, 11 soil and seven silt samples) identified a 900-metre-long metasedimentary belt and quartz veins with silt samples up to 167 parts per billion gold (S-17) at Mastodon South. The Mastodon property (approximately 109 hectares) includes a Minfile showing that consists of an 820-metre-long, northwest-trending siliceous replacement zone 0.3 metre to 1.8 metres wide in a 30-to-60-metre-wide belt of Middle-Upper Jurassic Hazelton group metasedimentary rocks within granitic rocks of the Eocene Coast plutonic complex. Precious metal assays range from trace gold and silver over 1.5 metres to 11.0 grams per tonne gold and 3.4 grams per tonne silver over 0.46 metre.

Next steps

Based on compilation work completed by the company and the exciting new results of both TDG and Goliath, the company is intending to complete fieldwork this summer, consisting of surface sampling, prospecting and geological mapping, followed by possible airborne surveys.

About Coast Copper Corp.

Coast Copper's flagship projects are the Copper Kettle postdiscovery copper-gold-molybdenum project, located in the Island copper cluster on northern Vancouver Island; the former-producing copper-gold Empire mine, also located on northern Vancouver Island; and the former-producing Emerald and Virginia silver mines located near the Huckleberry mine and Smithers in Northern British Columbia. Coast Copper has an additional 18 projects in British Columbia that are available for acquisition, partnering or option that are strategically located in seven advanced mining camps that include the Toodoggone, Golden Triangle, Anyox, Goliath Resources (Golddigger), Babine, Bralorne and Sullivan camps providing exposure and leverage to millions of dollars being spent on neighbouring properties. Coast Copper's strategy is to optimize the value of each mineral property within its portfolio through a combination of prospect generation and discovery-focused, high-impact exploration while minimizing share dilution through active deal making.
