NORTHWEST COPPER ANNOUNCES NEW HIGH-GRADE DRILL

RESULTS AT KWANIKA

HIGH-GRADE INTERCEPTS EXPAND NEAR-SURFACE FOOTPRINT AT KWANIKA.

HIGHLIGHTS INCLUDE 230.95m AT 0.99 % CuEQ AND 155m OF 0.93% CuEQ

Vancouver, BC – September 9, 2021 – NorthWest Copper (“NorthWest” or “the Company”) (TSX-V: NWST)

(OTCQX: NWCCF) is pleased to announce that assays have been received from the initial surface expansion

and confirmation drilling at Kwanika. The results, with consistently high-grade intercepts starting at 25 to

36 metres downhole, support Kwanika as a unique high-grade porphyry copper-gold deposit and expand

the near-surface footprint of potential open pit mineralization. Additional Kwanika results will follow for

ongoing deeper drilling and step -out drilling. As a reminder our first East Niv drill program is also in

progress. Additional assay results will be disclosed as results become available.

Highlights are given below:

• Drillhole K-21-205 – 230.95m1 at 0.99% CuEq2 including 94.6m at 1.62% CuEQ

• Drillhole K-21-207 – 187m at 0.81% CuEq including 73.0m at 1.22% CuEQ

• Drillhole K-21-208 – 196m at 0.65% CuEq including 52.5m at 1.47% CuEQ

• Drillhole K-21-209 – 154.5m at 0.93% CuEq including 53m at 1.66% CuEQ

• Drillhole K-21-211 – 137.5m at 0.91% CuEq including 71m at 1.34% CuEQ

A plan map and figures are included below.

The 2021 drill program at Kwanika was designed to expand and better define coherent zones of high grade

Cu-Au mineralization and use this as a basis for an updated resource estimate and future economic study.

Since the creation of NorthWest in March 2021 we have focussed on our high-grade Stardust deposit and

on the high-grade portion of Kwanika. We delivered favourable Stardust metallurgy in April 2021 and an

updated and expanded high-grade Stardust resource in May 2021. The current drill assay results enhance

and expand the near -surface high-grade portion of Kwanika. These results, along with a set of deeper

holes still to be released, will support an updated Kwanika resource planned for Q4 2021. Kwanika is

(%) + (Gold (g/t) x 0.7182) + (Silver (g/t) x 0.0090).

unique not only in having a distinct and coherent high-grade zone of mineralization, but also by having it

come close to the surface. The current near-surface results clearly support this.

The assays from this drilling enhance the existing block model 3. The holes extend high -grade

mineralization into previously modelled lower grade zones and add confidence to the interpolated grade

in other areas. Tw o of the holes are outside of the historic grade boundary. These two holes, K-21-207

and K-21-208, can be seen to intersect grades up to and above 1% copper equivalent (“CuEQ”) into areas

with lower grade to no grade. This can be seen in Figure 2.

Peter Bell, President & CEO of NorthWest states: “These are excellent first results and a great start for our

new company, NorthWest Copper. They highlight the high -grade nature of our Kwanika deposit and

increase the near -surface footprint of that mineralization. The new results will be incorporated in our

updated Kwanika resource planned for Q4 2021 . We will have additional drill results from deeper holes

and step out targets to follow these results.”

“The expansion of the Kwanika high-grade footprint compliments the new high-grade resource at our

adjacent Stardust project, presented to the market in May. We believe both deposits to be exceptional

and the results to date support our strategy of advancing these scalable high-grade Cu-Au projects. Every

hole in this program intercepted significant intervals of copper equivalent grade above 1% starting at the

bedrock surface as shallow as 25 m . The identification of additional high-grade so close to surface is

especially valuable to the project as it is easy to access and early in the life of a potential mining

operation.”

These results represent the first 2 ,000 metres of a program of more than 8 ,500 metres of drilling at

Kwanika. We expect additional results later this month for the deeper Kwanika holes followed by ongoing

results from East Niv and Kwanika regional exploration.

The drillholes in this release were all collared as angle holes with an inclination of - 50 to -65 degrees. All

exhibit similar geology. Mineralization in all holes was encountered directly below overburden with the

strongest mineralization occurring coincident with porphyritic monzonite with strong potassic alteration.

Alteration associated with high-grade includes intense quartz stockwork veining with chalcopyrite with

minor bornite. Zones of moderate grade mineralization occur in monzonite, monzodiorite and diorite

with moderate potassic alteration and quartz veining grading into propylitic alteration with local zones of

mineralized potassic alteration as vein and fracture selvage alteration . This intrusive complex is cut by

feldspar porphyry dikes. A full table of results is provided below:

Quality Assurance / Quality Control

Drilling completed at Kwanika in 2021 was supervised by on-site NorthWest personnel who collected and

tracked samples and implemented a full QA/QC program using blanks, standards and duplicates to

monitor analytical accuracy and precision. The samples were sealed on site and shipped to Bureau Veritas

(BV) in Vancouver BC for analysis. BV’s quality control system complies with global certifications for

Quality ISO9001:2008. Core samples were analyzed using a combination of BV’s MA20 0 process for all

samples (ICP-MS/4 acid digestion ) and the MA 370 process for overlimit samples of higher level

concentration (ICP-ES/4 acid digestion). Gold assaying was completed with FA 430, a 30- gram fire assay

with AAS finish. A silica wash was used between high-grade samples to ensure no sample carry over.

Technical aspects of this news release have been reviewed, verified and approved by Ian Neill P.Geo., Vice

President Exploration of NorthWest, who is a qualified person as defined by National Instrument 43 -101

– Standards of Disclosure for Minerals Projects.

Stardust

As a continuation of the Kwanika drilling, NorthWest is drilling three holes at Stardust. These are intended

to test continuity of mineralization below the main trend and parallel to the main trend. The three-hole

program is expected to commence shortly.
