NorthWest Copper Completes 2024 Drill Program at Lorraine - Top Cat Exploration Site

NorthWest Copper (“NorthWest” or “the Company”) (TSX-V: NWST) is pleased to announce the successful completion of the 2024 drill program at the Lorraine-Top Cat project in north-central British Columbia. Crews will begin demobilizing from the field once the diamond drill core has been processed.

Approximately 800 meters of drilling was carried out at the regional Nova and Road IP Targets, as previously reported on July 4, 2024. Three holes were drilled—one at Nova (356 meters) and two at Road IP (totaling 456 meters). The drill holes are now being logged and sampled. Around 470 half-core diamond drill samples, including QAQC samples, will be sent to Activation Laboratories in Kamloops for analysis.

Assay results are anticipated in the coming weeks, and a comprehensive report on the findings and observations will be issued upon receipt of the assays. These results will be used to refine future targets at Lorraine-Top Cat, aligning with the Company’s strategy to expand its mineral resource base through exploration.

The Project spans over 65,000 hectares and is situated in north-central British Columbia, 280 km northwest of Prince George, BC, and approximately 45 km from NorthWest’s Kwanika-Stardust Project. The Lorraine deposit is classified as a silica-undersaturated alkalic copper-gold porphyry deposit, similar to the Galore Creek and Mount Polley deposits. Mineralization at the Lorraine - Top Cat Project is primarily hosted by Early Jurassic syenite and pyroxenite intrusions within the Duckling Creek Syenite Complex (DCSC), though additional targets like Road IP are associated with other phases of the Jurassic Hogem batholith or older Takla Group volcanic rocks. A modern mineral resource estimate (MRE) completed in 2022 for parts of the Lorraine deposit includes indicated resources of 12.952 Mt with grades of 0.55% Cu and 0.16 g/t Au, and inferred resources of 45.252 Mt with grades of 0.43% Cu and 0.10 g/t Au at a 0.20% copper cut-off grade. Previous disclosures suggest that gold concentrations may be underestimated and that silver was not included in the estimation due to inconsistent analysis of these metals in historical drill holes. The MRE covers the surface and includes the Lower Main, Upper Main, and Bishop Zones, as well as the surrounding rock. Copper sulphides are present in various combinations of chalcopyrite, bornite, and hypogene chalcocite, with generally low pyrite concentrations.

NorthWest Copper is a copper-gold exploration company with a portfolio of projects in British Columbia. Positioned in a top-tier jurisdiction with a strong project lineup, NorthWest Copper is well-placed to benefit from the growing global copper market. The company is dedicated to responsible mineral exploration, which includes collaborating with First Nations to ensure that future development adheres to stewardship best practices and respects traditional land use.
