Copper Quest Initiates 32.4 Square Kilometer Induced Polarization
Survey over the Stars Copper-Molybdenite Property
May 19, 2026
Vancouver, British Columbia – Copper Quest Exploration Inc. (CSE: CQX; OTCQB: IMIMF; FRA: 3MX)
(“Copper Quest” or the “Company”) is pleased to announce that it has commenced a 32.4 km2
induced polarization (“IP”) geophysical survey on its 100% owned Stars Property (“Stars” or the
“Property”). Stars is a porphyry copper-molybdenum (“Cu-Mo”) project covering 9,693 hectares (“ha”)
in the Stikine region of British Columbia, situated approximately 60 km north of Imperial Metals
Corporation’s (“Imperial Metals”) past producing Huckleberry Cu-Mo mine, 50 km north-northeast of
Surge Copper Corp’s advanced stage Berg copper project, and 30 km north-northwest of Vizsla Copper
Corp’s Poplar copper-gold project. Imperial Metals is exploring Huckleberry and its surrounding claims
for additional Cu-Mo resources.
This very large IP survey represents the first time this geophysical technique has been applied across
the full extent of the Stars Property, including over the Tana Zone discovery area and its along-strike
extensions. Induced polarization is a proven method for detecting sulphide mineralization, the type
of copper-bearing material found at Stars, at depth and at distance from known drill holes. By imaging
the full 32.4 km² footprint of the magnetic anomaly, the Company aims to determine the true scale of
the mineralized system in terms of strike length, width, and depth, and to identify potential new drill
targets beyond the current Tana Zone.
Highlights of the Stars Property:
• Road accessible, 9,693 ha property in a top tier exploration and mining district, the Bulkley
Porphyry Belt.
• A 230 X 180 metre (“m”) domain (the “Tana Zone”) of chalcopyrite-molybdenite-bornite quartz
stockwork that has been intersected from surface to greater than 350 m depth. The zone is
open in two directions as well as to depth. Drill Intersection highlights include:
o 0.466% Cu over 195.07 m* in drill hole DD18SS004 from 23.47 m
o 0.200% Cu over 396.67 m* in drill hole DD18SS010 from 29.37 m
o 0.205% Cu over 207.27 m* in drill hole DD18SS015 from 163.98 m
• A highly prospective, approximately 5 X 2.5 kilometre (“km”), annular magnetic anomaly that
is interpreted as an altered monzonite intrusion and surrounding hornfels (Figure 1).
• Numerous underexplored soil and induced polarization geophysical targets within the larger
magnetic anomaly (Figure 1).
Brian Thurston, President & CEO of Copper Quest, commented: "Copper Quest controls 9,693 ha
covering the Stars Property and prospective surrounding area with two complementary exploration upsides
being an established zone of higher-grade mineralization that the Company can grow and define, and a
much broader under-explored area with high potential for new discovery. This is a very large geophysical
program that combined with the historic 9,016 m of drilling will help guide exploration to provide the best
information to make new discoveries in this very large anomaly that has a footprint five times that of the
Huckleberry Mine. Combined with the contiguous 5,389 ha Stellar Property, Copper Quest has assembled a
dominant land position and created a unique opportunity that unlocks a district scale copper porphyry
project in the Bulkley Porphyry Belt. Given the global movement towards AI, electrification, environmental
concerns, infrastructure development, and the forecasted demand for copper, the combined properties
make a very compelling exploration package."
The Stars Property
The 9,693 ha, road-accessible Stars Property is located in central British Columbia, 40 km southwest
of Houston. It hosts porphyry copper-molybdenum mineralization associated with a Bulkley Suite
monzonite stock. The Bulkley Suite is linked to mineralization at Imperial Metals' past-producing
Huckleberry mine, 60 km to the south, and other porphyry deposits in the region. Three drilling
campaigns on the Stars Property, totaling 9,016 m, have identified a broad area of anomalous copper,
and molybdenum within the monzonite stock. The most important drilling to date is at the Tana Zone
(Figure 1), where the contact between the stock and surrounding volcanic rock contains chalcopyrite,
molybdenite and bornite bearing quartz stockwork veining. Tana Zone drilling has defined an
approximately 230 x 180 m domain with significant copper and molybdenum grades (Table 1).

CS-07 58.51 170.38 111.87 0.255 54
Outside the Tana Zone, most drilling on the property encountered altered and anomalous mineralized
monzonite within an approximately 1.8 x 1.0 km area marked by a broad magnetic low (Fig. 1). While
there is potential for an undiscovered porphyry deposit within the monzonite intrusion, Copper
Quest's future exploration will concentrate on specific IP targets along the contact zones. Several
historical drill holes are believed to have approached this contact, with assays at their bottoms
showing increased copper and molybdenite values (Table 2). Their drill logs also indicate an increase
in quartz-chalcopyrite-molybdenite ± bornite veins with pink K-feldspar altered selvages, similar to
those found in the Tana Zone.

About Copper
Copper is an essential industrial metal at the heart of the global energy transition and modern
infrastructure. It plays a critical role in electrification, renewable energy systems, electric vehicles, data
centers, and smart technologies. With global demand rising and new supply challenged by declining
grades, complex permitting, and underinvestment, the copper market faces persistent deficits and
growing geopolitical scrutiny. Recent U.S. policy announcements, including import tariffs and
initiatives to secure domestic and allied supply chains, underscore copper’s strategic importance and
the need for resilient, localized resource exploration, development, production and processing
capacity.

Copper Quest has a 100% interest in the past-producing Alpine Gold Mine located approximately 20
kilometers northeast of the City of Nelson British Columbia, spanning 4,611.49 hectares with a 2018
National Instrument 43-101 Standards of Disclosure for Mineral Projects historical inferred resource
of 268,000 tonnes, estimated using a cut-off grade of 5.0 g/t Au and an average grade of 16.52 g/t Au,
that represents an inferred resource of 142,000 oz of gold* (*McCuaig & Giroux, March 6, 2018, NI43-
101 Technical Report for the Alpine Property, BC, Canada. Further drilling is necessary by the Company to
upgrade/verify the estimate. The QP has not done sufficient work to make the resource current and the
Company is not treating the estimate as current.). Apart from the Alpine Mine itself the property hosts
4 other less explored significant vein systems including the past -producing King Solomon vein
workings, the Black Prince and the Cold Blow veins system, and the Gold Crown vein system. *The
Company has not yet completed sufficient work to verify the 2018 historic inferred resource results.
