NORTHWEST ANNOUNCES TARGET MODEL AT KWANIKA WITH HIGHER-GRADE

ZONES OVER SIGNIFICANT THICKNESSES TO SUPPORT NEW STRATEGIC

APPROACH

Vancouver, BC – April 10, 2025 – 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 strategi c initiatives to enhance the value of the existing PEA 1 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 inspect ion 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 r e-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).

February 17, 2023, with an effective date of January 4, 2023, filed under the Company’s SEDAR+ profile at www.sedarplus.com.

2CuEq assumes long term USD metal prices of $2210/oz gold, $4.25/lbs copper and $27.70/oz silver, calculated as follows:CuEq = Cu %

+ (Au g/t /31.1035g/oz * $2210/oz) / ($4.25/lb * 2204.62lbs/t) * 100 + (Ag g/t /31.1035g/oz * $27.70/oz) / ($4.25/lb*2204.62lbs/t) * 0

• The Central area has two key parallel zones trend ing 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).

Regardless of area, the two parallel higher -grade target zones are separated by up to 20m of

unmineralized dykes. Other smaller target zones are also beginning to be identified that require more

drilling to define (Au_HG_3, Cu_HG_7, Cu_HG_9).

Drill holes at Kwanika have multiple orientations that complicate the interpretation and reporting of

historical results. To help, t he Company has created a 3D model available via Seequent Central’s Open

Scene with the goal of assisting stakeholders to understand historical drilling in the context of the new

target model. The target model was interpreted into distinct higher -grade zones based on position and

orientation of mineralization from historical drill holes . Using the current mineral resource drill hole

database, t he drill holes were intersected with the target model and screened for the more

representative, higher-angle intercepts reported in Table 1 , representing 52 of a total of 90 drill holes

intersecting the target model. The selected drill hole locations are shown in Figure 1 with collar details

provided in Table 2.

The higher-grade target model also helps to assess potential next steps. Additional infill and step -out

drilling is required to confirm, extend, and enhance the confidence of the higher -grade target zones and

planning is underway to define a phased drill program, to achieve a regular 50m drill spacing across some

target zones in addition to testing targets beyond the model extents.

VP Business Development and Exploration Geoff Chinn, P. Geo ., stated, “ The higher-grade targets

identified within the current Kwanika mineralization allows the Company to assess opportunities to

extend and better define the zones in leading to potential alternative mining methods and an updated

PEA. The two broad parallel zones identified represent a combined mineralized true width ranging

between 30m and 45m at higher grades between 1.5% and 2.5% CuEq that provide an interesting basis

for alternative potential bulk mining methods than the block cave envisioned in the current PEA. In

addition, considering the grade-recovery relationship developed during the metallurgical test work used

in the current PEA, the potential for enhanced recoveries by flotation alone looks promising for both

copper and gold.”

The Company will provide additional updates on its progress in advancing the plan for the coming year.

The target model was developed by Geoff Chinn P.Geo. and checked by comparing the zones to logged

geology, reviewing plans and cross-sections, and reviewing core photos. In addition, the target model was

peer-reviewed by James Lang Ph.D, P.Geo..
