VANCOUVER, British Columbia, April 10, 2025 (GLOBE NEWSWIRE) -- NorthWest Copper (“NorthWest” or the “Company”) (TSX-V: NWST) announces a new higher grade target model for Kwanika, which represents the first step in advancing on one of the Company’s strategic initiatives to enhance the value of the existing PEA1 on its 100% owned Kwanika-Stardust project through a staged development approach.

A new three-dimensional (3D) target model, available here (Kwanika Higher-Grade 3D Target Model), has been developed to improve the understanding of the geometry and continuity of higher-grade zones within the current Mineral Resource at Kwanika. The higher-grade zones are based on an inflection in the gold assay distribution, indicative of a higher-grade sub-population above 1.0g/t. Visual inspection of higher-grade values shows them to be continuous and correlate with 3D zones that define the new target model. Gold values were used as the primary basis for correlations, as it is believed gold is less susceptible to re-mobilization and as such a better indicator of primary mineralizing pathways than copper. The resulting target zones generally form two wide parallel zones that take various turns as they migrate 30 degrees up-plunge from west to east, potentially enhancing previous models.

The 3D target model zones support a target size range between 15 to 30 million tonnes of higher-grade mineralized material mostly from two broad parallel zones with a combined mineralized true width ranging between 30m and 45m at higher grades between 1.5% and 2.5% CuEq2.

CEO Paul Olmsted stated, “The creation of the target model is a significant step in moving forward on our strategy to focus on higher-grade zones at Kwanika. The target model will provide a base for executing on our planned phased approach with the initial phase focusing on a higher-grade, lower capital cost development project. This is in line with our objective to enhance the value of the current PEA.”

The higher-grade target zones are grouped into three areas based on zone orientations, summarized as follows:

  • The Western area has two key parallel zones trending east-west, dipping 47 degrees north, with drill intercept grades between 1.7% and 1.8% CuEq, and true widths estimated between 20m and 24m each (Au_HG_1, Au_HG_2).

  • The Central area has two key parallel zones trending north-south, dipping 55 degrees east, with drill intercept grades between 2.2% and 2.5% CuEq, and true widths estimated between 10m and 14m each (Zones Au_HG_4, Au_HG_6).

  • The PEA pit area has two key sub-parallel zones trending east-west, variably dipping between 49 and 66 degrees, with drill intercept grades between 1.7% and 2.4% CuEq, and true widths estimated between 11m and 29m each (Au_HG_5, Au_HG_10). In addition, a low-grade zone is interpreted to potentially support open pit mining in this area (Au_LG_8).
