Coast Copper Corp. provided results from a September 2023 field program following up on several geophysical and gold in soil anomalies at its optioned Empire Mine property ("Empire Mine" or the "Property") on northern Vancouver Island, British Columbia ("BC"). This exploration work included expanding the gold ("Au"), copper ("Cu") and tellurium ("Te") in soil and rock anomaly to over a 250 meter ("m") x 500 m area around the newly discovered B3 showing which reported several chip samples averaging 31.60 grams per tonne ("g/t") Au, 15.97 g/t Te, and 0.11% cobalt ("Co") in sample MWR2023-009. Additional work included initial prospecting and sampling in an underexplored 1-kilometer ("km") x 2 km area between the Upper Merry Widow Trend ("Upper Trend") and Lower Benson Lake Mine Trend ("Lower Trend"), known as the Middle Trend. This area was highlighted during geological compilation and fits with the model of probable multiple stacked thrust systems, which indicate potential for mineralization in this area. Preliminary investigations show promising initial surface results. A total of 76 soil and 25 rock samples were collected during this field program from targeted areas across the Upper and Middle Trend zones on the Property. Coast Copper's technical team collected 42 soil samples and 10 rock samples in the area surrounding the B3 discovery, specifically between the Bluebird 1, Marten and Snowline mineral
occurrences. Notable assay results from sampling include outcrop samples up to 11.1 g/t Au and up
to 191.50 g/t Te above the Snowline showing, a 9.60 g/t Au rock float sample and 368.00 ppb Au in
soil samples between Bluebird 1 and Bluebird 2 and up to 2,100.00 ppb Au in soil samples down slope of Snowline. This work has extended the soil anomaly to an area roughly 250 m in width and 500 m in length and shows good potential to link the Bluebird 1, Bluebird 2 and Snowline showings with newly discovered B3 showing. Emerging Middle Trend (1 km x 2 km area between Upper Trend and Lower Trend) Fieldwork by Dr. Jim Oliver in 2022 identified the presence and importance of regional thrust systems in the Merry Widow Pit and along the Upper Trend. A thorough review of the recent drillhole data and relevant historical work led to a geological model of multiple stacked thrust faults, or thrust panels, occurring between the Upper Trend and the Lower Trend potentially linking up mineralization between these deposit areas. The importance of cross structures within these favorable trends has also been recognized as a significant control on mineralization across the Property. This concept was further validated when examining historical drill-hole logs from 2007 located above the Benson Lake Mine which indicated mineralized intervals occurring hundreds of meters above the Benson Lake Mine in areas that should have been barren limestone. As such, initial prospecting and sampling was completed with the expectation that mineralization could occur within this 1 km x 2 km area, that had previously seen no systematic work. Coast Copper's preliminary work in this area that was previously not thought to be prospective, shows promising copper and gold values from both rock and soil samples. A total of 34 rock 15 soil samples were taken across the emerging Middle Trend zone. Rock samples returned assay values up to 1.90% Cu and up to 1.25 g/t Au, with one soil sample returning 9,995.00 ppm Cu and 1,210 ppb Au. These encouraging results indicate that further work is warranted in this area. Quality Assurance/Quality Control ("QA/QC") Procedures: Soil samples were taken at 25 m spacings when possible and by up to 50 m spacings in areas of interest. All samples were taken from the B horizon soil profile. 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. Soil samples were dried and screened to 80 mesh and then analyzed in 20g samples with multi-element ICP-MS Aqua Regia digestion (IMS-111). Rock samples were dried and crushed to 70% passing 2mm mesh and split to 250g samples which were pulverized to 85% passing 75m and then analyzed by Aqua Regia, ICP- AES/MS (IMS-131). Copper assays greater than 10,000 ppm were completed with ICF-6Cu, 4acid, ICP-AES ore grade analysis.
