NORTHWEST COPPER REPORTS LONG INTERCEPTS WITHIN THE NORTHERN
EXTENSION OF THE KWANIKA DEPOSIT, INCLUDING 364.20 METRES AT 0.27%
CUEQ
Vancouver, BC – October 24, 2022 – NorthWest Copper (“NorthWest” or “the Company”) (TSX -
V: NWST) (OTCQX: NWCCF) is pleased to announce results from four holes drilled in the northern
lobe of the Kwanika Deposit ’s Central Zone 1 (Figures 1 and 2). These holes returned long
intercepts of copper and gold mineralization. Highlights include:
• K-22-237: 364.20 metres2 of 0.27% CuEq3 from 27.80 to 392.00 metres including:
o 24.55 metres of 0.86% CuEq from 229.30 to 253.85 metres
• K-22-238: 167.85 metres of 0.32% CuEq from 33.55 to 201.40 metres
“These holes confirm that strong copper and gold mineralization continue in the northern portion
of Kwanika Central Zone,” said President and CEO Peter Bell. “These holes demonstrate that the
Kwanika system contains a cluster of deposits over three kilometers, from South Zone to these
recent holes in the north of the Kwanika Central Zone. Further drilling results are expected from
the South Zone at Kwanika as well as our other projects in the coming weeks.”
Drill Results Discussion
We have now released results from 20 of the 30 drill holes competed at Kwanika in 2022. We
anticipate that we will continue to publish results from the 2022 program over the remainder of
the year
Diamond drill holes K -22-237, 238, and 246 were designed to target structurally controlled
higher-grade mineralization in the northern portion of the Central Zone (Figure 2). They
complement previously released drill holes K-22-234, 235, 236, 239, 241, 24 3, 244, and 245 4.
The results of all of these holes collectively demonstrate continuity of grade within the currently
defined resource.1 Including the previously reported holes, the northern portion of the Central
Zone was drilled over approximately 450 metres in strike length and results demonstrate that
mineralization continues to the north of the conceptual open pit5 (Figure 2). All three holes in

recovery is assumed to be 91% for Copper, and 75% for Gold and Silver. The following equation was used to calculate copper equivalence: CuEq =
Copper (%) + (Gold (g/t) x 0.5666) + (Silver (g/t) x 0.007 4

this release hit mineralization that is relatively shallow with overburden cover ranging from 27.80
to 43.50 metres downhole depth. Results from the drilling in the northern extent of the
conceptual open pit will also help constrain our structural and geological models and help focus
future exploration programs.
K-22-237 has the longest intercept with 364.20 metres of 0.27% CuEq (Figure 3). This intersection
is on the same section as K-22-236 that was reported as 179.60 metres with 0.33% CuEq 6, and
the two holes demonstrate continuity of grade on this section. Hole K-22-237 also intersected
mineralization below the current conceptual open pit and could add value to the project in the
future. Mineralization in K -22-237 is hosted in andesites to 117.85 metres depth with strong
pervasive propylitic alteration and chalcopyrite hosted in quartz-sulphide veins. This is followed
by diorite with strong pervasive propylitic alteration and an overprint by potassic alteration. The
copper mineralization is in chalcopyrite and occurs as disseminations and in quartz-sulphide veins
that become the predominant style of mineralization downhole. From 277.50 metres to end of
hole the dominant alteration is pervasive potassic alteration and chalcopyrite occur s as
disseminations and hosted in quartz-sulphide veins.
K-22-238 was drilled on a section approximately 90 metres to the north of K-22-237 (Figures 2 &
4). It intersected 167.85 metres grading 0.32% CuEq and is on the same section as K-22-241 that
was previously reported at 305.75 metres with 0.29% CuEq6. Again, these two holes show grade
continuity in the conceptual open pit area. Mineralization in K -22-238 is hosted by diorite with
strong pervasive propylitic alteration that is locally overprinted by moderate to strong potassic
alteration. Chalcopyrite occurs in quartz-sulphides veins and as disseminations.
K-22-246 was drilled in the northern extent of the conceptual open pit area and returned 145.70
metres of 0.20% CuEq including 64.60 metres of 0.28% CuEq with most of this intersection sitting
outside of the current conceptual open pit volume (Figure 5). Mineralization is hosted by diorite
with moderate pervasive propylitic alteration along with irregular zones of pervasive potassic
alteration. Chalcopyrite mineralization is either disseminated or hosted in quartz -sulphide veins
or both. Results from this hole further demonstrate that the mineralized system is present and
is potentially open to the north of the current proposed open pit.
K-22-247 was drilled approximately 600 metres north-northwest of the conceptual open pit and
tested a geophysical induced polarization anomaly (Figure 1). The drill did not intersect
significant mineralization but it did intersect geology that explains the anomaly, as well as faults
that validate our current structural geology model.

Quality Assurance / Quality Control
Drilling completed at Kwanika in 2022 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 and to AGAT Laboratories (AGAT) in Calgary AB.
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 overlimits completed
with a gravimetric finish. AGAT’s quality control system complies with global certifications for
Quality ISO 9001:2015. Core samples were analyzed using a combination of AGAT’s 201 -071
process for low level concentrations (ICP-MS/4 Acid digestion) and the 201-079 process for higher
level concentrations (Sodium Peroxide Fusion/ICP-OES). Gold assaying was completed with 202-
055, a 30 -gram fire assay with ICP finish . Base metal overlimits were finalized with Fusion/ICP -
OES method.
