News Release
NORTHWEST COPPER DISCOVERS NEW MINERALIZED ZONE AT THE
LORRAINE-TOP CAT PROJECT
First Ever Drill Assays from the Road IP Target Return 104.7 metres at 0.13% Copper
Vancouver, BC – October 10th, 2024 – NorthWest Copper (“NorthWest” or “the Company”) (TSX-V: NWST)
is pleased to announce the discovery of a new mineralized zone at the Lorraine -Top Cat pro ject ( the
“Project”). The first ever drill assays from the Project’s Road IP Target returned 104.7 metres of 0.13%
copper (“Cu”). This area has never been drilled before and the closest historical drill hole is 6.3 kilometres
away. Highlights from the Project’s 2024 drill program include:
• IP-24-002: 104.7 metres1 of 0.13% Cu from 58.3 metres downhole;
o including 7.4 metres of 1.10% Cu from 147.6 metres downhole.
• IP-24-001: 60.0 metres of 0.06% Cu from 127.0 metres downhole.
• NV-24-001: 24.0 metres of 0.08% Cu from 241.0 metres downhole.
“We are very encouraged by the results from holes drilled at the Road IP and Nova Targets this summer,”
said Tyler Caswell, NorthWest Copper’s VP Exploration. “ We drilled two new target areas and hit base
metal mineralization in all of the holes.”
“The results from this drilling support our thesis that we can find more mineralized centres outside of the
existing Lorraine resource,” commented Mr. Caswell. “There is still a lot of discovery potential at Lorraine-
Top Cat. The geology we are seeing at the Road IP target area is similar in style to a calc-alkalic porphyry
copper system, analogous to the Central Zone at our Kwanika-Stardust project, and which is potentially a
large tonnage, high-grade target type.”
Exercise of Top Cat Option
As of the date of this news release, the Company has now made all required cash payments, issued all
required common share payments, and incurred the required exploration expenditures under an option
agreement entered in July 2019. The Company has now acquired 100% ownership of the Top Cat claims,
subject to a 3% net smelter royalty (NSR). The Company may purchase 2% of the NSR for $2,000,000 at
any time prior to the first anniversary of commercial production on the Top Cat property.
2024 Lorraine-Top Cat Program
Approximately 800 m etres of drilling was completed in July 2024 at the regional Nova and Road IP
Targets2. The objective of th e program was to expand known mineralization to areas outside of the
current Lorraine mineral resource estimate (“MRE”) (indicated resources of 12.952 million tonnes (“Mt”)
grading 0.55% Cu and 0.16 g/t gold (“Au”), and inferred resources of 45.252 Mt grading 0.43% Cu and 0.10

g/t Au at 0.20% copper cut -off grade)3,4. Three holes were drilled, one at the Nova Target (356 metres)
and two at the Road IP Target (456 metres total). The program was successful in its objective as it
discovered mineralization in two previously un-drilled target areas. Follow-up drilling is recommended at
these targets to delineate size potential and the potential high-grade core of the system.

Road IP Target
The Road IP Target is defined by an IP chargeability anomaly that is coincident with a magnetic low (630 x
425 metres) with a subtle magnetic high in the middle ( Figure 2). Additionally, historical surface
geochemical samples show a geochemical anomaly coincident with these geophysical anomalies. Outcrop
has not been identified in the area and the target area remains covered by a veneer of glacial sediments.
The closest historical drill hole at Lorraine-Top Cat is 6.3 km away from this target area. Two diamond drill
holes were completed from a single drill pad at the Road IP Target and both encountered mineralization.

The first hole IP -24-001 was drilled to a depth of 1 87 metres and stopped in mineralization due to
challenging ground conditions, whereas the second was drilled to a depth of 269 metres.
Drill hole IP-24-001 (Road IP Target)
IP-24-001 was the first of two diamond drill holes drilled at the Road IP Target (Figure 2 & Figure 3). Drilling
was terminated prior to planned target depth due to difficult ground conditions. D rilling results show a
broad zone of anomalous copper-silver mineralization with 60.0 metres of 0.06% Cu and 0.2 g/t Ag from
127.0 metres to the end of hole. Mineralization remains open downhole. Chalcopyrite occurs on fracture
coatings and within quartz- sulphide veinlets hosted by a quartz monzodiorite to quartz monzonite
intrusion. The mineralized interval starts within a fault zone that marks a significant change to a more
intense potassium feldspar alteration that hosts chalcopyrite-pyrite and trace molybdenite
mineralization.

Drill hole IP-24-002 (Road IP Target)
Hole IP-24-002 was the second of two diamond drill holes at the Road IP T arget. Assay results show a
broad zone of anomalous copper-silver mineralization with 104.7 metres of 0.13% Cu , 0.01 g/t Au and
0.5 g/t Ag from 58.3 metres , which includes 7.4 metres of 1.10% Cu , 0.04 g/t Au and 5.6 g/t Ag from
147.6 metres downhole . Mineralization occurs as chalcopyrite and pyrite hosted in quartz- sulphide
veinlets and as fine disseminations and fracture coatings in quartz monzodiorite to quartz monzonite
intrusion. Higher grade mineralization is coincident with zones of increased quartz-sulphide vein density
and an increase in potassium feldspar alteration intensity.

Drill hole NV-24-001 (Nova Target)
NV-24-001 was drilled at the Nova target and was designed to test a highly chargeable Induced
Polarization (IP) anomaly that is coincident with a very strong magnetic high (Figure 5). Historical surface
geochemical samples also showed polymetallic mineralization coincident with the anomaly. The closest
historical drill hole on the Lorraine-Top Cat project is 11 km away from this drill collar. Assay results show
discrete zones of anomalous precious and base metal mineralization, including 12.0 metres of 0.07% Cu,
0.2 g/t Ag, and 0.04 g/t Pd from 208.0 metres, and 24.0 metres of 0.08% Cu, 0.4 g/t Ag, and 0.02 g/t Pd
from 241.0 metres downhole (Figure 6). Mineralization in both zones occurs as finely disseminate d
chalcopyrite and pyrite in fine -grained pyroxenite with abundant chlorite and magnetite, and patchy
biotite and epidote alteration. In the lower interval, c halcopyrite also occurs within a 1.5-metre interval
of sheared quartz- carbonate-sulphide veins at the end of the intersection , which could demonstrate a
structurally controlled zone of mineralization.

There are two additional zones with anomalous palladium-silver mineralization with 7.15 metres of 0.15
g/t Pd and 0.5 g/t Ag from 54.0 metres, and 16.0 metres of 0.11 g/t Pd and 0.4 g/t Ag from 172.0 metres
(Figure 6). There is also a weak correlation in these zones with copper, with each intersection returning
0.03% Cu & 0.04% Cu , respectively. Mineralization in both intersections is also hosted in fine -grained
pyroxenite with abundant chlorite and magnetite, with patchy biotite and epidote alteration.

The Lorraine-Top Cat Project
The Lorraine-Top Cat Project covers 65,000 hectares and is located in north-central British Columbia, 280
km northwest of Prince George, BC and approximately 4 5 km north of NorthWest’s Kwanika -Stardust
Project. The Project comprises the contiguous Lorraine and Top Cat properties.
Rock types across the Project are dominated by intrusions of the Hogem Batholith that were emplaced
into mafic volcanic and sedimentary rocks of the Late Triassic Takla Group. Intrusions include mafic to
felsic phases of the calc-alkalic Thane Creek suite and, possibly, the younger Osilinka suite of the Hogem
Batholith, which was subsequently intruded by Early Jurassic, alkalic ultramafic to felsic rocks of the
Duckling Creek Syenite Complex (“DCSC”). At least 30 exploration targets for copper -gold-silver±PGE
mineralization are distributed across the Project. Most prospects are hosted by the DCSC, with additional
prospects, such as the Steelhead and Road IP targets, hosted by the older phases of the Hogem. A smaller
number of copper-gold targets are associated with Late Triassic intermediate calc-alkalic intrusions on the
east side of the property, including the Dorothy -Rhonda and Cat Mountain targets. Currently, the most
important feature of the Project is the Lorraine deposit. This significant deposit is located near the centre
of the Project tenure and is a silica-undersaturated alkalic copper-gold-silver-PGE porphyry deposit, which
is the same classification as the Galore Creek and Mount Polley deposits. Mineralization at the Lorraine
deposit is hosted mostly by Early Jurassic syenite and pyroxenite intrusions of the DCSC.
A compliant mineral resource estimate (MRE) was completed in 2022 that includes indicated resources of
12.952 Mt grading 0.55% Cu and 0.16 g/t Au, and inferred resources of 45.252 Mt grading 0.43% Cu and
0.10 g/t Au. As described in previous disclosures, h owever, gold concentration is likely under- reported
and silver was not included in the estimation because many historical drill holes were inconsistently
analyzed for the two metals. The MRE extends to surface and includes the Lower Main, Upper Main, and
Bishop Zones and intervening, more sparsely drilled rock. Copper sulphides manifest various combinations
of chalcopyrite, bornite and hypogene chalcocite, and the concentration of pyrite is generally low. Gold,
silver, copper, and palladium in the deposit are all closely related, as illustrated by flotation results on five
scoping metallurgical composites from the Lower Main and Bishop Zones, which returned cleaner
flotation recoveries of up to 94% for copper, 71% for gold, 92% for silver and 76% for palladium to a high-
grade concentrate that contains 31 -54% copper and has low concentrations of potentially deleterious
trace metals6.
Quality Assurance / Quality Control (QA/QC)
Drilling completed at Lorraine-Top Cat in 2024 was supervised by on-site NorthWest personnel. Samples
were collected, tracked and a full QA/QC program was implemented using blanks, standards and field
duplicates to monitor analytical accuracy and precision. The samples were sealed on site and shipped to
Activation Laboratories Ltd. (“Actlabs”) in Kamloops BC. Actlabs quality control system complies with
global certifications for quality ISO 17025. Drill core samples were analyzed using a combination of Actlabs
1F2 process for low level concentrations (4-Acid Digestion, ICP-OES) and the 8-4 Acid ICP-OES process for
higher level concentrations ( 4-Acid Digestion, ICP -OES with automatic overlimits for base metals and
silver). Gold, platinum and palladium assaying was completed with 1C-OES, a 30-gram fire assay with ICP
finish.
