NORTHWEST COPPER ADDS MORE HIGH-GRADE

DRILL RESULTS AT KWANIKA

HIGH-GRADE INTERCEPTS CONTINUE TO EXPAND THE NEAR-SURFACE FOOTPRINT.

HIGHLIGHTS INCLUDE 202 METERS OF 0.74% CUEQ INCLUDING 45.8 METRES OF 1.57% CUEQ

Vancouver, BC – September 28, 2021 – NorthWest Copper (“NorthWest” or “the Company” ) (TSX-V:

NWST) (OTCQX: NWCCF) is pleased to announce that additional assays have been received from our near-

surface high-grade expansion and confirmation drill program at Kwanika. This second batch of high-grade

assays from the 2021 program at Kwanika were drilled north of previously released results. Like the results

released previously1, these continue to expand the near -surface footprint of mineralization. W ith high-

grade starting at the bedrock surface , these new assays also continue to support our focus on the best

part of this unique deposit . Results from deeper drilling and step -out drilling at Kwanika , drilling at

Stardust, and our first pass East Niv drill program are also pending.

Highlights are given below:

• Drillhole K-21-212 – 202.2m2 at 0.74% CuEq3 including 45.8m at 1.57% CuEq

• Drillhole K-21-213 – 38.5m at 0.85% CuEq

• Drillhole K-21-214 – 63.5m at 0.77% CuEq

A plan map and figures are included below.

Drillhole K-21-212 returned higher grades than the surrounding block model grades as indicated on Figure

2. Mineralized intervals appear outside of previously modelled high-grade4 suggesting potential resource

growth. K-21-213 shows mineralized material, including significant > 1% copper intervals at the bedrock

surface where previously low grade was modelled. Finally, K -21-214 provides higher grade intercepts in

2 True widths of the reported mineralized intervals have not been determined .

3 Assumptions used in USD for the copper equivalent calculation were metal prices of $3.25/lb. C opper, $1,600/oz Gold, $20/oz Silver, and recovery is

assumed to be 100% given the level of metallurgical test data available. The following equation was used to calculate copper equivalence: CuEq =

Copper (%) + (Gold (g/t) x 0.7182) + (Silver (g/t) x 0.00 90).

the upper part of the hole vs the existing blocks. Importantly all drillholes have their highest -grade

intervals starting at or close to the bedrock surface.

The 2021 Kwanika drill program is consistent with our high -grade growth strategy and focusses on

expanding and improving understanding of the best grade material. NorthWest has focussed on our high-

grade Stardust deposit and on the high -grade portion of Kwanika since the C ompany was created in

March. Our previous Kwanika assay results ¹ followed releases of favourable Stardust metallurgy in April

20215 and an expanded high-grade Stardust resource in May 2021. The near-surface results, along with a

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

Peter Bell, President & CEO NorthWest Copper states: “These excellent near-surface results in the north

part of the Kwanika deposit continue the trend of enhancing and expanding near -surface, high-grade

mineralization. We continue to see high-grades from surface and importantly we have significant

intercepts where we previously had no grade or low-grade modelled.”

“We are executing on our plan to expand the size of Kwanika through a targeted angle drill program .

Throughout this drill program, we have encountered grades higher than adjacent resource blocks, which

should favourably affect our upcoming resource as well as the proposed PEA. The continued success of

the drilling reflects the high-grade of Kwanika and speaks to the quality of NorthWest’s portfolio.”

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 overbu rden 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 from the program to date 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 AQ270 process for low

level concentrations (ICP -ES/MS aqua regia) and the MA270 process for higher level concentrations

(ICPES/MS 4 acid digestion). Gold assaying was completed with FA330, a 30 -gram fire assay with ICP -ES

finish. Base metal overlimits were finalized with titration, with gold overlimits completed w ith a

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