Coast Copper Highlights its Anyox Area Projects and Congratulates Both TDG and Goliath

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^1,4 and which it acquired in July 2025. The Company also wishes to congratulate Goliath who has been reporting numerous high-grade gold intercepts from its Surebet discovery¹ approximately 20 kilometers ("km") to the north of Anyox. Coast Copper holds some of the only mineral claims adjacent and internal to the Goliath ground.

Adam Travis, CEO, comments: "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 (see Figure 1)²

The Company holds two main blocks of claims in the Anyox area consisting of the Anyox East Islands (approximately 2,002 hectares ("ha")) and the Bonanza South (404 ha) 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 dykes warrant 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 the potential VMS trend highlighted on Figure 1 sourced from the TDG Gold website².

Golddigger Area Claim Holdings (see Figure 1)²

The David property (approximately 1,408 ha) is a thin (1 km) by 7 km east –west and 7 km north-south strip adjacent and internal to Goliath's Golddigger property¹.  In 1990 a small sampling program (3 rock, 11 soil and 7 silt samples) identified a 900 m long metasedimentary belt and quartz veins with silt samples up to 167 ppb Au (S-17) at "Mastodon South"⁵. The Mastodon property (approximately 109 ha) includes a minfile⁶ showing which consists of an 820 m long NW trending siliceous replacement zone 0.3 to 1.8 m wide in a 30- to 60-m-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 m to 11.0 grams per tonne gold and 3.4 grams per tonne silver over 0.46 m ^3,5.

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 post-discovery Cu-Au-Mo project located in the Island Copper Cluster on northern Vancouver Island, the former producing Cu-Au 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 B.C. Coast Copper has an additional 18 projects in B.C. 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 neighboring properties. Coast Copper's strategy is to optimize the value of each mineral property within our portfolio through a combination of prospect generation and discovery focused, high-impact exploration while minimizing share dilution through active deal-making.
