NorthWest Reports Near Surface Intercept of 44.0 Metres of 0.62% Copper and 0.42g/t Gold (1.01% CuEq) at Kwanika from 172 Metres
NorthWest Reports Near Surface Intercept of 44.0 Metres of 0.62% Copper and
0.42g/t Gold (1.01% CuEq) at Kwanika from 172 Metres
TORONTO, Nov. 19, 2025 -- NorthWest Copper Corp. (“NorthWest” or the “Company”) (TSX-V: NWST) is pleased to announce
continued positive assay results from the fifth drill hole of its 2025 program at the Company’s 100% owned Kwanika project in
British Columbia. Drill hole K-25-278 intersected two broad zones of near-surface copper-gold mineralization, including a
highlight intercept of 44 metres grading 0.62 % Cu, 0.42 g/t Au (1.01% copper equivalent1, “CuEq”).
Drill hole K-25-278 achieved two key objectives: it confirmed near-surface mineralization over significant widths within the
current open-pit mineral resource and improved the confidence in both the position and thickness of the upper Central Zone in
an area with limited historical drilling. Notably, the upper Central Zone was intersected closer to surface than expected,
suggesting changes in geometry as it approaches higher-grade areas within the Pit Zone, which could indicate that these
zones are potentially continuous.
Drill Hole Highlights:
Pit Zone: 80 metres of 0.59% Cu, 0.16g/t Au (0.75% CuEq) from 47 metres, and
44 metres of 0.62% Cu, 0.42g/t Au (1.01% CuEq) from 172 metres.
Central Zone: 36 metres of 0.65 % Cu, 0.64 g/t Au (1.25% CuEq) from 222 metres, including:
10 metres of 0.79 % Cu, 0.77 g/t Au (1.50% CuEq) from 222 metres, and
18 metres of 0.77 % Cu, 0.80 g/t Au (1.51% CuEq) from 238 metres.
In the upper portion of the hole, two broad zones of near-surface mineralization were encountered within the current open-pit
resource (see Table 1). The first zone (Zone 8) consists of a wide, copper-dominant interval of continuous mineralization, while
the second zone (Zone 10) is narrower and carries higher gold relative to copper grades. Together, these intervals indicate an
east-west lateral metal zonation trend that continues into the Central Zone intercept where gold to copper ratios approach 1:1.
This pattern provides valuable geological insight that may support an improved understanding of metallurgical recoveries across
the deposit.
Paul Olmsted, CEO of NorthWest stated: “This hole builds on the strong momentum we’ve established at Kwanika. The
results confirm continuous near-surface mineralization and reinforce the potential for a high-grade starter pit that could
enhance the project’s near-term economics. In the upper Central Zone, results continue to demonstrate strong and consistent
higher-grade mineralization as expected. The combination of broad, higher-grade near-surface intervals and continuous
mineralization within the Central Zone strengthen our confidence in delivering meaningful improvements to project economics in
an updated Preliminary Economic Assessment (“PEA”).”
The Company’s 2025 expanded drill program, totalling 6,435 metres, is aimed at defining higher-grade zones within the current
mineral resource. The program focuses on underground targets that could support a more selective, top-down, mining method,
while also evaluating higher-grade areas within the open-pit mineral resource that could serve as a starter pit. Results from the
first five holes have met or exceeded these expectations, highlighting the opportunity to improve on the economics outlined in
the 2023 PEA2. The Company expects to release additional results from the remaining thirteen holes over the coming weeks.
Geoff Chinn, VP Business Development and Exploration of NorthWest added: “Hole K-25-278, continues to confirm the
continuity of copper dominate mineralization within the Pit Zone over substantial widths inside the current open-pit mineral
resource. Better definition of these zones will directly improve the quality of the mineral resource and future mine plans based
on it. In the upper Central Zone, the hole returned a combined true width of 25.4 metres grading 1.50% CuEq, within our target
range of 1.5-2.5 times the current 1.0% CuEq underground mineral resource 3. The Central Zone was intersected higher in the
hole than expected, suggesting changes in zone geometry as it approaches higher grade areas in the Pit Zone. Results from
additional holes in the 2025 program will determine if these two zones are continuous. We are also pleased with metallurgical
test work progress aimed at improving copper and gold recoveries, with initial results expected before year end.”
Kwanika Exploration Program
On April 10, 2025, NorthWest announced a refined model for its flagship Kwanika project (“Target Model”), highlighting three
key higher-grade zones: the Pit, Central and Western Zones. These zones target grades of 1.5% to 2.5% CuEq over combined
true thicknesses of 30 to 45 metres, potentially supporting a more selective top-down bulk underground mining method.
The 2025 exploration program is designed to validate, infill and expand on the Company’s understanding of higher-grade
copper-gold mineralization within the current mineral resource, with the aim of supporting alternative bulk mining methods.
Early results from the first five holes, including hole K-25-278, confirm significant progress toward these objectives.
Figure 1 illustrates the position of hole K-25-278 relative to the Target Model Central and Pit Zones. Collar locations and
continuous mineralized intercepts are summarized in Table 1 and Table 2. Hole locations for the program are available in the
news release dated September 2, 2025.
A summary of the geological aspects of the hole is presented below.
Figure 1: Cross Section of Target Model at K-25-278 Drill Location
Hole K-25-278 was drilled with HQ core size and sampled on approximately 2-meter intervals from sawn half core material. The
hole was drilled on a 285° azimuth with a -60° dip to a depth of 341 metres. The main purpose of the hole was to validate the
location of the upper Central Zone mineralized interval (Zone 4) in an area poorly defined by previous low-angle holes and to
test a step-out of the lower Central Zone mineralized interval (Zone 6) towards the north.
At 220 metres, the hole intersected the upper Central Zone (Zone 4) approximately 25 metres higher than predicted, indicating
an offset or shift in direction of the zone in this area. The interval comprises a broad, well mineralized section with elevated
gold values relative to copper, consistent with metal zonation trends within the Central Zone.
Further downhole at 272 metres, the hole intersected the lower Central Zone interval (Zone 6). This interval returned lower
grades hosted in a quartz stockwork, and displayed higher gold to copper ratios, aligned with zonation trends in the lower
Central Zone.

Quality Assurance / Quality Control
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.
