NORTHWEST COPPER ANNOUNCES SUCCESSFUL STEP-OUT RESULTS FROM 2021

KWANIKA DRILLING. MINERALIZATION ENCOUNTERED OUTSIDE THE RESOURCE

AREAS WITH 137 METRES OF 0.52% CUEQ INCLUDING 34 METRES OF 1.30%

CUEQ.

Vancouver, BC – March 10, 2022 – NorthWest Copper (“NorthWest” or “the Company”) (TSX-V:

NWST) (OTCQX: NWCCF) is pleased to announce that drilling at Kwanika has encountered strong

copper-gold grades in holes designed to expand the footprint of mineralization at the Kwanika

Central and Kwanika South Zones. These are the first results from 2021 Kwanika drilling that are

outside of the Central Zone footprint. Highlights include:

• K-21-223: 137.00 metres1 of 0.52% Copper Equivalent (“CuEq”) 2 including 34.00 metres

of 1.30% CuEq;

• K-21-221: 99.70 metres of 0.28% CuEq.

The 2021 Kwanika program focussed on enhancing high-grade copper-gold mineralization within

the known resource footprint of the Central Zone. This program was very successful incl uding

identification of a new style of very high -grade in hole K -21-2173. NorthWest also conducted a

limited step-out program, designed to test areas of sparse drilling around both the Central Zone

and the South Zone. To date the Central Zone contains the bulk of the tonnes and grade at

Kwanika. K-21-221 was drilled north of the Central Zone and K-21-223 and K-21-224 were drilled

at the South Zone.

K-21-223 is a high -grade intercept in the South Zone. South Zone mineralization is distinctive

from that of the Central Zone and includes significant levels of molybdenum as well as copper,

gold and silver. It is separated from the Central Zone by a fault system and is a little over one

kilometer to the southeast (Figure 1). The South Zone was drilled with mostly shallow and wide-

spaced holes by our predecessor company Serengeti Resources. Both new holes are encouraging

with K-21-223 being the highest grade and filling a sparsely drilled gap. More work is planned.

1 True widths of the reported mineralized intervals have not been determined

2 Assumptions used in USD for the copper equivalent calculation were metal prices of $3.25/lb. Copper, $1,600/oz Gold, $20/oz S ilver, 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 0.0090). For intersections in the South Zone where Molybdenum is present, assumptions used in USD for the

copper equivalent calculation also include $9.00/lb. Molybdenum, 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 0.0090) + (Molybdenum (%)

x 2.77).

K-21-221 was drilled several hundred metres north of the limit of the Central Zone resource

shape4(Figure 2). The target was developed with a combination of geochemical vectoring and a

coincident induced polarizatio n (IP) geophysical anomaly. The hole was drilled in a different

orientation than the surrounding holes to test a potentially mineralized intrusive body. The long

interval of anomalous gold and copper that was intersected opens up a large volume of undrilled

material to further exploration. This will be followed up in 2022.

“These results provide additional targets and, importantly, expansion potential at Kwanika ”

commented President and CEO Peter Bell. “The southern holes highlight the opportunity around

the South Zone, which is much less drilled than Kwanika Central Zone. The drilling by the team

continues to deliver high grades on multiple targets, consistent with our high- grade corporate

focus. The northern hole shows the undrilled po tential north of the Kwanika Central Zone,

identified through interpretation by our geologists. We look forward to following up these results

in the 2022 program.”

The drill hole s reported here encountered materials geologically like those intersected by

previous drilling campaigns. At Kwanika Central, c opper-gold porphyry -style mineralization is

hosted by intermediate to felsic intrusions and by greatly subordinate mafic volcanic rocks .

Highest grade intervals commonly correlate with the abundance of very well mineralized quartz-

sulphide veins that conta in chalcopyrite variably accompanied by bornite . D isseminated

mineralization occurs in strong potassic alteration between and related to the se veins, but also

in areas of pervasive potassic alteration. Mineralization is dominated by hypogene sulphide, with

a mostly narrow zone of paleo-supergene mineralization that is commonly present at the top of

the mineralized interval. Late-to post-mineral dykes locally cut the copper-gold mineralization.

The South Zone is hosted by a quartz monzonite intrusion that has not been encountered at

Kwanika Central. Mineralization is hypogene and occurs in zones of potassic alteration related to

quartz-sulphide veins, and more locally in altered breccias. The South Zone to date is

distinguished by higher molybdenum grades than Kwanika Central.

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 MA200 process for low level concentrations (ICP -MS/4 Acid digestion) and

the MA370 process for higher level concentrations (ICP -ES/4 acid digestion). Gold assaying was

completed with FA430, a 30-gram fire assay with AAS finish. Base metal overlimits were finalized

with titration where required, with gold overlimit s completed with a gravimetric finish. A silica

wash was used between high-grade samples to ensure no sample carry over.
