Coast Copper Confirms and Expands Upon 3 Regional Structures and Vein Systems on its Scottie West Property in the Golden Triangle

VANCOUVER, Oct. 24, 2023 - Coast Copper Corp. ("Coast Copper" or the "Company"; TSX-V: COCO) is pleased to provide an update on exploration of its 100% owned Scottie West property (the "Property") located in British Columbia's ("BC") Golden Triangle district approximately 35 kilometers ("km") northwest of Stewart, BC and 8 km west of the past producing Scottie Gold Mine¹ (see Figure 1).

In September 2023, the Coast Copper technical team, together with technical advisor Jeff Kyba, P.Geo., visited the property focused on prospecting three key precious metal mineralized zones: Leduc Northeast Ridge ("Leduc NE"), Leduc East-Central Ridge ("Leduc East Central") and the Southeast Exposure ("SE Exposure"). These zones are located along the southwest extension of the interpreted mineralized trend that includes neighboring Scottie Resources Corp.'s Domino Zone, Blueberry Zone¹ and the historical producing Scottie Gold Mine¹ (see Figure 1). In addition to following up sampling from 2021, the program benefited from glacial retreat and snow melt which provided significant new exposures to identify and expand veins and structures. New showings were discovered each day on the property.

Adam Travis, Coast Copper's CEO commented: "Our field observations and results from our September program are very encouraging and consistent with structural and magnetic trends observed at the adjacent Scottie Resources property. New bedrock exposures resulting from the receding glaciers have led to the discovery of new mineral showings in altered and sheared volcanic rocks on our property. In addition to the vein and outcrop sampling, the anomalous precious and base metal assay results have provided a good indicator of favorable geochemistry and will help delineate additional prospective target areas for future exploration."

Coast Copper's exploration program included prospecting, sampling and mapping of veins and structures in areas of newly exposed, altered and sheared volcanic and sedimentary rocks. 130 rock samples were collected from vein, grab and float materials, which resulted in anomalous gold, silver and tellurium assay values at the SE Exposure and Leduc East Central Ridge locations. Surficial sampling of vein and select float samples at the SE Exposure and Leduc East Central produced ten samples ranging from 0.5 to 5.5 grams per ton ("g/t") gold ("Au"), 10.9 to 189.0 g/t silver ("Ag"), and up 0.75% lead ("Pb") and 0.59% zinc ("Zn"), with two anomalous tellurium ("Te") values of 16.99 and 25.26 g/t noted at the SE Exposure (see Table 1).

The Leduc NE, Leduc East Central and SE Exposure zones are hosted in Jurassic age andesitic volcanic rocks from the Unuk River Member of the Betty Creek Formation, which are in contact with the Summit Lake stock, part of the early Jurassic aged Texas Creek Plutonic Suite. At both the SE Exposure and Leduc East Central areas, a sedimentary package consistent with Stuhini Group sediments was identified which could indicate the lower contact of the Hazleton-Stuhini stratigraphic contact to be confirmed with detailed mapping. The precious metal mineralization on the Property consists of east-west trending, steeply dipping quartz-carbonate-pyrite-arsenopyrite-pyrrhotite veins that are characteristic of other intrusion-related, mesothermal precious metal mineralized veins reported along this regional mineralized trend.

Quality Assurance/ Quality Control ("QA/QC") Procedures
Sampling completed on the project in 2023 was supervised by on-site Coast Copper personnel and sub-contractors who collected and tracked samples and implemented a full QA/QC program using blanks, standards and duplicates to monitor analytical accuracy and precision. The samples were sealed on site and shipped to MSA Labs in Langley BC for analysis. MSA Labs' quality control system complies with global certifications for Quality ISO9001:2008. Rock samples were dried and crushed to 70% passing 2mm mesh and split to 250g samples which were pulverized to 85% passing 75?m. The samples were then analyzed by a multi-element 20g 3:1 Aqua Regia, ICP-AES/MS (IMS-131), Ultra Trace Level. Silver assays greater than 100 g/t were completed with ICF-6Ag, 4 acid, ICP-AES ore grade analysis.
