Northwest Copper Corp. Announces Standout Assay Results from the Fourth Drill Hole of Its 2025 Drilling Program
NorthWest Copper Corp. announced standout assay results from the fourth drill hole of its 2025 drilling program at the Company's 100% owned Kwanika project in British Columbia. Drill hole K-25-280 successfully intersected both the Pit and Central copper-gold zones, highlighted by an exceptional intercept of 36 metres grading 0.80 % Cu, 3.21 g/t Au (3.67% copper equivalent1, “CuEq”) in the Central Zone. This drill hole returned results that exceeded expectations in both grade and thickness. Drill hole K-25-280 achieved two important objectives. The hole advanced our understanding of the Central Zone, expanding the area of high-grade copper-gold mineralization within the core of the system, with thicknesses and gold grades greater than expected. The hole also encountered broad zones of mineralization in the Pit Zone, confirming the location and grade of mineralization and supporting the potential for near-surface open pit mineral resources. Pit Zone: 66 metres of 0.48 % Cu, 0.16 g/t Au (0.64% CuEq) from 116 metres, including: 30.0 metres of 0.55 % Cu, 0.22 g/t Au (0.77% CuEq) from 126 metres, Central Zone: 60 metres of 0.67 % Cu, 2.12 g/t Au (2.11% CuEq) from 269 metres, including: 12 metres of 0.79 % Cu, 0.58 g/t Au (1.33% CuEq) from 269 metres, and 36 metres of 0.80 % Cu, 3.21 g/t Au (3.67% CuEq) from 285 metres. The Company’s 2025 expanded 6,435 metre drill program is designed to define higher-grade zones within the current mineral resource, with a particular focus on underground targets. The program is focused on zones with grades approximately 150% - 250% higher than the grades incorporated in the 2023 PEA2. Results to date from the first four holes have met or exceeded these expectations, demonstrating the potential opportunity to improve on the economics of the 2023 PEA. The Company expects to release additional results from the remaining fourteen holes over the coming weeks. Drilling intersected multiple intervales of near-surface, lower-grade, mineralization surrounding the Pit Zone. This intercept confirms the location and grade of near-surface copper-gold mineralization with attractive grades for potential inclusion in open pit mineral resources, returning: 0.49% Cu, 0.18g/t Au, and 1.38 g/t Ag for 0.66 % CuEq over 26.6 m with an estimated true thickness of 15.6 m starting at 57.0 m, and 0.48% Cu, 0.16g/t Au, and 1.56 g/t Ag for 0.64 % CuEq over 66.0 m with an estimated true thickness of 46.7 m starting at 116.0 m, including: 0.55% Cu, 0.22g/t Au, and 1.96 g/t Ag for 0.77 % CuEq over 30.0 m with an estimated true thickness of 21.2 m starting at 126.0 m. Below the Pit Zone, the hole intersected and confirmed an outer higher-grade copper interval within the Central Zone, characterized by a relatively high copper to gold ratio consistent with the Target Model expectations, returning: 0.58% Cu, 0.28g/t Au, and 1.73 g/t Ag for 0.85 % CuEq over 16.0 m with an estimated true thickness of 13.9 m starting at 239.0 m, including: 0.70% Cu, 0.32g/t Au, and 1.97 g/t Ag for 1.01 % CuEq over 6.0 m with an estimated true thickness of 5.2 m starting at 239.0 m. Further down, the hole intersected a wide mineralized interval within the Central Zone that infills an area poorly defined by low-angle drillholes. The intersection is sub-divided into continuous upper and lower intervals, separated by unmineralized dykes, that have high gold to copper grade ratios, suggesting a lateral metal zonation within the Central Zone. The Central Zone intersection was materially wider than predicted by the Target Model, returning: 0.67% Cu, 2.12g/t Au, and 2.11 g/t Ag for 2.57 % CuEq over 60.0 m with an estimated true thickness of 52.0 m starting at 259.0 m, including: 0.79% Cu, 0.58g/t Au, and 3.02 g/t Ag for 1.33 % CuEq over 12.0 m with an estimated true thickness of 10.4 m starting at 269.0 m, and 0.80 % Cu, 3.21 g/t Au, and 2.22 g/t Ag for 3.67 % CuEq over 36.0 m with an estimated true width of 31.2 m starting at 285.0 m. Drilling the Central Zone from east to west has returned consistent, representative, continuous mineralized widths and improved the understanding of lateral metal zonation within the deposit that enhances the project’s potential and can guide future exploration. Drilling at Kwanika in 2025 was designed and supervised by NorthWest, implemented by InData Geoscience with assay QA/QC checks by Explore Geosolutions. Samples were collected, tracked and an external QA/QC program was implemented using blanks and standards to monitor analytical accuracy and precision. The samples were sealed on site and shipped to Activation Laboratories Ltd. (“Actlabs”) in Kamloops BC. The laboratory’s internal quality control system complies with global certifications for quality ISO 17025. Drill core samples were analyzed using a combination of Actlabs multi-element 1F2 analysis for low level concentrations (4-Acid Digestion, ICP-OES) and the 8-4 Acid ICP-OES analysis for higher level concentrations (4-Acid Digestion, ICP-OES with automatic over limits for base metals and silver). Gold, platinum and palladium assaying was completed with 1C-OES method, using a 30-gram fire assay with ICP finish analysis. In addition, about 5% of the sample pulps are re-assayed at a secondary laboratory to confirm reproducibility and check for bias.
