Cassiar Gold Reports New Geophysical Targets
NEWS RELEASE
Cassiar Gold Reports New Geophysical Targets
CALGARY, ALBERTA – (May 22, 2025) – Cassiar Gold Corp. (TSX-V: GLDC, OTCQX: CGLCF) (“Cassiar Gold” or the
“Company”) is pleased to report the results of a series of geophysical surveys conducted across the Cassiar Gold
Property in northern British Columbia during the 2024 exploration program (Figure 1). The DCIP, magnetic, and
VLF-EM surveys have identified multiple anomalies. These anomalies may be representative of new prospective
structures, extensions of known gold-bearing quartz veins, and broad areas of potential hydrothermal alteration
and disseminated sulphide mineralization in host rocks similar to those that host the Taurus deposit . These
results provide critical structural and geological context to advance the pipeline of targets for the 2025 field -
based investigations and future drill targeting.
Highlights:
The 2024 surface program was designed to enhance the geological, geochemical, and geophysical base for
exploration beyond established drill targets, providing further context to support potential new discoveries and
expansion of known mineralized areas. Several geophysical surveys, reported here, were conducted concurrent
to the Company’s 2024 diamond drill program. These included 3D DC-resistivity and induced polarization (DCIP),
magnetics, and very low frequency electromagnetic (VLF-EM) surveys. The newly acquired data has identified
multiple anomalies that will contribute to exploration program planning.
Geophysical surveys completed at Cassiar North (drone -supported magnetics and DCIP) and Cassiar South
(drone-supported VLF -EM) identified multiple high-priority targets that have not been tested by previous
exploration. Collectively, these datasets:
• Outlined multiple new prospective targets parallel to structures which control mineralization in known
productive trends
• Extended the interpreted strike length of several known gold-bearing quartz vein systems
• Identified several previously untested areas with signatures that suggest broad areas of potential
prospective alteration of host rocks
“The results from our 2024 field program suggest a structural and geologic setting with potential for mineralized
vein systems to span several kilometres. ” said Jill Maxwell, VP Exploration for Cassiar Gold Corp. “ Anomalies
identified using new and historical datasets have identified a geophysical signature interpreted to be related to
the mineralizing hydrothermal system which extends well beyond the current areas of drilling, opening up new
ground for exploration in the upcoming field season.”

Property Overview
The Cassiar Gold Property hosts several regional prospects with potential to host Taurus deposit-style
mineralization in outlying areas to the Taurus bulk-tonnage Inferred gold resource estimate of 1.4 million
ounces grading 1.14 grams per tonne (g/t) gold (Au) [1]. High-grade shear veins comprise the deposit style
typical of the past-producing mines at the Cassiar South project area which holds potential to host new
parallel veins associated with high-grade mineralization, and extensions and fault offsets of past-producing
vein systems.
Cassiar North Project Area: DCIP and Drone Magnetics Surveys
The Company contracted Pioneer Exploration Consultants Ltd. (“Pioneer”) to complete a drone-based
magnetic survey over a 60 km2 area of the northern Cassiar project. Dias Geophysical Ltd. (“Dias”) was
engaged to complete a 3D direct current-resistivity and induced polarization (DCIP) survey over
approximately 6 km2 (Figures 1,2,3,4) of this area with the objective to expand modern data coverage and
integrate with 2023 datasets to evaluate the potential for direct detection of quartz vein-associated
disseminated sulphide mineralization beyond the extent of the inferred mineral resource. These surveys also
aimed to evaluate the potential to identify structural and lithological features that may play a role in
controlling, or may host, gold-bearing quartz veins.

North. Apparent magnetic lows (blue dashed lines), peripheral to magnetic highs, bear spatial association with
moderate to strong chargeable responses (yellow dashed lines) coincident with areas host to known gold-showings
at surface, with & without previous early-stage drilling (blue & white stars, respectively).
Magnetics
The domain that hosts the 2022 Taurus Resource exhibits a strong magnetic response in the survey area with
several discrete subcircular magnetic features throughout the domain, one of which coincides with the footprint
of the Taurus deposit (Figure 2).
Moderate chargeability anomalies are apparent in the DCIP survey, w hich may represent direct-detection of
gold-related sulphide mineralization occurred near the edges of magnetic anomalies – a pattern noted at both
the Taurus deposit and the Wings Canyon brownfields target.
The analytical signal magnetic data revealed several areas of apparent lower magnetism peripheral to magnetic
highs, thought to represent areas of magnetite destruction. These zones are interpreted to reflect hydrothermal
alteration related to gold-bearing vein systems, similar to the Taurus deposit.
Importantly, newly identified structural lineaments may represent east-northeast extensional splays from a
major northwest regional control to mineralization in the district. The interaction of these primary and
secondary structures are known to influence the distribution of gold on the property and will be key targets in
the coming field season.
DCIP
Dias generated a 3D inversion model of chargeability, conductivity, and resistivity, integrating 2023 and
2024 survey datasets. The integrated datasets outline three distinct geophysical domains, each with
promising exploration targets (Figures 2,3).
Domain 1 initially surveyed in 2023 and includes both the Taurus deposit and Wings Canyon target
area, hosts moderate chargeability responses associated with known gold and disseminated sulphide
mineralization. Anomalies identified east and west of Taurus, and east of Wings Canyon, in areas with
lower apparent magnetic responses are considered prospective for follow up.
Domain 2 is characterized by low resistivity and magnetic responses, interpreted to be due to
underlying sedimentary rocks, allowing the contact to be traced under cover. A series of discrete
chargeability anomalies near the boundary of this domain may represent pyritic alteration envelopes
with potential to host gold mineralization and warrant further ground truthing.
Domain 3 exhibits a banded series of resistivity and chargeability lineaments which may indicate a new
area of gold-bearing quartz veins with carbonate rich and pyritic alteration envelopes. This series of
features is characterized by low magnetic responses and alternating lineaments of high resistivity/low
chargeability and moderate resistivity/high chargeability. Much of this area is under cover, as such
several IP anomalies have not been explored and present high-quality targets for follow up
investigations.

Drone VLF
The Company contracted Pioneer Exploration Consultants Ltd. (“Pioneer”) to complete a drone-based
magnetic survey over a 7.5 km2 area at the Cassiar South project area (Figure 5). The survey was designed to
evaluate the suitability of high-resolution modern VLF data to detect known near-surface structures that could
host gold-bearing quartz veins, key faults, and geological contacts at the project area, while potentially
identifying new exploration targets.
The survey area included the East Bain vein – a known and unmined segment of the past-producing Bain Mine
– and the thrust contact between mafic volcanic rocks, known host to gold-bearing veins on the property, and
overlying sediments.
The survey successfully outlined the relatively flat lying thrust contact. Results suggest that structures which
host the known gold-bearing veins in the area often correspond with breaks or changes in orientation of the
thrust fault contact. The presence of such breaks or deflection features will contribute to exploration targeting
and prioritization.
Importantly, responses suggest a series of east-northeast trending structural lineaments, including several on-
trend with known gold-bearing quartz vein segments. This observed response aligns with the unmined East
Bain vein of the past-producing Bain Mine where survey results suggest the vein system may extend well
beyond its currently known extent. Several other prospective parallel lineaments were also highlighted and are
considered high priority for follow-up investigation.

strike extensions of known vein systems as well as new blind parallel veins.
Summary
The recent DCIP, magnetic, and VLF-EM surveys at the Cassiar Gold property have successfully identified multiple
anomalies which may be representative of new prospective structures, extensions of known gold-bearing quartz
veins, or broad areas of potential hydrothermal alteration and disseminated sulphide mineralization in host
rocks similar to those that host the Taurus deposit mineralization. These results provide critical structural and
geological context to advance the pipeline of targets to guide 2025 exploration, including field- based
investigations and drill targeting. The technical team is actively integrating survey outcomes into program
planning as we look toward the upcoming field season.
Survey Specifications
The magnetic survey was completed using a GEM Systems GSMP-35U UAV Magnetometer mounted and
suspended below a Hercules X4 UAV, with the sensor set to 35 m above ground level. Lines were spaced at
50 m, flown at an azimuth of 022.5o, for a total of 1384 line-kilometres flown.
The principal VLF airborne sensor used was a GEM Systems GSM-90AVU UAV-VLF system being carried in a
towed bird with a heavy lift Hercules X8 multirotor UAV, with the sensor set to 45 m above ground level.
Lines were set at 50 m spacing and 022.5o orientation, for a total of 155 line-kilometres flown.
The DCIP survey was completed using the DIAS32 acquisition system with a Dias GS5000 25kW transmitter,
and a rolling distributed 3D array with pole-dipole transmitter configuration. The inversion model derived
from integration of 2023 and 2024 provided near surface resolution of approximately 25 m x 50 m, and a
depth search of approximately 400-600 m.
The survey was comprised of 19 transmit lines alternating with 20 receiver lines, oriented southwest-
northeast with an azimuth of 016.5o and 175 m spacing. Transmitter stations were spaced 150 m apart and
receiver stations were spaced 75 m apart along their respective lines. Two current extensions were
extended beyond the ends of the transmit lines to increase depth of investigation along grid margins; a
current remote electrode station was established approximately 5 km west of the grid.
