Coast Copper Corp. (“Coast Copper” or the “Company”; TSX-V: COCO)is pleased to announce the staking of the Copper Kettle property (the “Property”) which is located between the past producing Island Copper Mine¹ and the Northisle Copper and Gold Inc¹. (“Northisle”) North Island project on northern Vancouver Island. This new property, along with Coast Copper’s Knob Hill NW property, now bookend the Northisle North Island Project¹. See Figure 1.
Adam Travis, Coast Copper CEO comments: “We continue to acquire prospective ground in areas of interest at low cost through staking. Our new Copper Kettle property, along with our Knob Hill NW property, which has been the subject of positive advancements since 2021, now bookend the Northisle property and are part of the 50-kilometer prospective trend for porphyry copper-gold deposits that originates at the Island Copper Mine, an open-pit copper mine that operated from 1971 to 1996. We will be completing work on both properties in 2025, as well as numerous other projects. We would like to extend our congratulations to the Northisle team on the recent positive Preliminary Economic Assessment for its North Island project. This advancement further solidifies the past and present potential of northern Vancouver Island.”
The Property totals 2,582 hectares (“ha”) and is located 3 kilometers (“km”)northwest of the past-producing Island Copper Mine and sits adjacent to the southeast side of Northisle’s property. The Property has six known “MINFILE” occurrences that have varied amounts of exploration work completed on them, with the most recent work recorded in 2016. The Property is prospective for both porphyry style mineralization as well as high-grade skarn mineralization. Historical exploration highlights include:
– 5 km skarn trend which has returned prospecting samples up to 5.8% copper (“Cu”), 19.9 grams per tonne (“g/t”) silver (“Ag”) and 0.17 g/t gold (“Au”) (in 1995). The results yield an average value of 1.66% Cu analyzing 20 surface pits at Hill 160 MINFILE and an average value of 0.27% Cu analyzing 2 surface pits at Hill 140 MINFILE ³.
– Copper-molybdenum porphyry occurrences that are on trend and on the boundary of the past-producing Island Copper Mine.
– Historical drilling around the Bay MINFILE occurrences intersected both skarn and porphyry style alterations with encouraging assays including 177 meters (“m”) of 0.44% Cu in drillhole 1986-E-69 ⁴, and 24.4 m of 0.83% Cu, 0.022% molybdenum (“Mo”) and 4.1 g/t Ag in drillhole 1989-E-90 ⁵.
– Drillhole Q89-1, completed in 1989 between Hill 160 and Hill 140 MINFILE occurrences, returned 0.91 m of 0.36% Cu ³.
– In 1997, a rock sample from the Hill 160 showing, which is noted as 25 centimeters wide, returned 3.7% Cu, 98 parts per billion (“ppb”) Au and 11.3 parts per million (“ppm”) Ag ⁶.
– A 1995 sampling of mineralized boulders at Kettle Pot MINFILE returned 1.18% Cu and 0.63 g/t Au ³.
Coast Copper also holds a 100% interest in the 7,769 ha Knob Hill NW property which is prospective for porphyry copper-gold mineralization similar to deposits located to the southeast as it occurs along a similar geological trend to the northwest with encouraging regional magnetic features. As announced on September 23, 2024 and December 10, 2024 , the Company continues to advance its knowledge of the Knob Hill NW property with significant copper geochemical anomalies peripheral to prospective magnetic features similar to those associated with the porphyry deposits in the region. Coast Copper’s fall 2024 sampling results returned elevated copper-in-soil (copper values up to 1,031 ppm) from the west central portions of the Knob Hill NW property that are associated with a 1.1 km by 3.6 km magnetic high. Strongly elevated gold values (up to 863 ppb) in moss mat samples occurring along the southeastern portion of the property have not yet been sourced but are located on the edge of a large magnetic high trend extending from the NW Expo region. This combined area represents a large 4 km by 7 km region showing magnetic data peripheral to anomalous copper and gold in limited sampling.
