IDEX Metals Drills 182.25m of 0.32% Cu From Surface at the Kismet Tourmaline Breccia, Freeze Project, Idaho
IDEX Metals Drills 182.25m of 0.32% Cu From Surface at the Kismet Tourmaline Breccia,
Freeze Project, Idaho
Vancouver, B.C. – September 10, 2025 - IDEX Metals Corp. (“IDEX” or the “Company”) (TSXV:
IDEX; OTCQB: IDXMF) is pleased to announce that the first ever drillhole completed by IDEX on
the Freeze property (“Freeze” or the “Property”) intersected 182.25 m of 0.32% Cu , from
surface. The drill hole, KSMT25001, intersected variable intervals of oxide copper mineralization
beginning at 1.5 metres downhole, with malachite, chalcocite, and chrysocolla occurring as
supergene replacement of primary chalcopyrite and minor bornite.
KSMT25001 was targeting the Kismet Tourmaline Breccia and intervals of historical copper
mineralization drilled in 1965. The first drillhole at Kismet has expanded the historical
mineralization to a minimum depth of 3 to 4 times the historical drilling, and has confirmed the
existence of a mineralized, near-surface, magmatic-hydrothermal copper system.
Key Highlights
● Significant highlights from drill hole KSMT25001 include:
○ 182.25 m grading 0.32% Cu, 1.08 g/t Ag, from 1.5 m
■ Including 3.2 m grading 1.44% Cu, 1.11 g/t Ag from 109.0 m
■ Including 1.0 m grading 1.41% Cu, 8.34 g/t Ag from 140.0 m
○ 89.34 m grading 0.26% Cu, 2.25 g/t Ag, from 189.0 m
■ Including 7.0 m grading 1.00% Cu, 10.84 g/t Ag from 217.0 m
■ Including 5.0 m grading 1.39% Cu, 8.85 g/t Ag from 243.0 m
○ 278 m grading 0.29% Cu across the entire length of the hole, and not accounting
for internal dilution.
○ Variable oxide copper mineralization (malachite, chrysocolla, and chalcocite
replacing primary chalcopyrite) was intersected from surface and persisted
throughout the entire 278 m length of KSMT25001.
● The ground-based magnetotelluric (MT) geophysical survey outlined a NW-SE
trending structural corridor with three major high-resistivity anomalies, interpreted as
potential intrusive centers, spatially associated with Kismet and Cuddy Mine (CM) targets.
● The second drill hole at Kismet, KSMT25002, has been completed to a depth of 422.7
m, with assays expected in October 2025.
● Field programs continue to generate new targets across the broader Freeze Project
area, setting the stage for a pipeline of future drill testing.

Clayton Fisher, CEO of IDEX Metals commented: “From the very first meter, hole KSMT25001
has confirmed a mineralized breccia and delivered continuous copper mineralization over its
entire length. This result highlights the potential of the Freeze property, and the Idaho Copper
Belt, to host large, near-surface copper mineralization in a Tier 1 jurisdiction.”

Drillhole Summary
Hole KSMT25001 was collared in a tourmaline breccia unit with mixed clasts of porphyritic
granodiorite, tonalite, diorite and early gabbro intrusives. The breccia is matrix supported with
secondary tourmaline and magnetite overprint which transitions to a tourminalized monzonite
intrusive matrix at depth. The tourmaline bearing matrix displays patchy weak-moderate potassic
alteration, which is associated with tourmaline infill and secondary copper oxide overprint. Oxide
copper mineralization in the tourmaline breccia matrix occurs as secondary malachite, chrysocolla
and chalcocite. The copper oxides are interpreted to be derived from primary chalcopyrite. There
is an overall transition from the oxide copper assemblage to sulfide-dominant chalcopyrite
mineralization downhole; however, localized oxide copper intervals are preserved at depths
exceeding 200 m. Structurally controlled chrysocolla and malachite also occur as fracture
coatings throughout the entirety of the hole. The mineralized breccia interval was encountered
over broader intercepts in hole KSMT25002.
KSMT25001 transitions to an early tonalite intrusive that contains intermittent 10 to 20 m intervals
of mineralized magmatic breccia. The hole bottomed in an earlier phase of diorite intrusive, which
showed malachite and chrysocolla as fracture coating mineralization.

MT Results
IDEX is also pleased to announce the results of the ground-based magnetotelluric (MT)
geophysical survey at the Freeze Property. The survey was completed by Moombarriga USA Ltd.,
over the course of 5 days with a total of 31 MT stations taken across the property. The primary
goal of the MT survey was to gain an understanding of the geophysical responses of the Kismet
and CM target areas in the subsurface, and to expand the known footprint of the targets into the
subsurface.
Hole KSMT25001 was drilled to the north at a steep angle, through moderately resistive features
ranging from 200-600 Ohm-m. This moderate feature was on the flank of a major >800 Ohm-m
body. This major resistive body will be tested in future drilling; however, the focus remains on
intersecting the moderately resistive features between the main resistive bodies, as these units
may correlate with zones of moderate silicification and disseminated sulfides.

Regionally, results of the survey indicate three major high-resistivity anomalies that trend along a
NW-SE corridor. A fourth, smaller high-resistivity anomaly can be found at depth, protruding from
the northwestern-most major feature. It was found that both the Kismet and CM targets occur
along the margins of the resistive centres. This may indicate the possibility that the resistive
features are unaltered or potentially potassically altered cores of a shallow intrusive body. It
should be noted that the resolution of the MT survey is decreased in the east and south of the
property due to a lack of station data.

seated features with broad less resistive (more chargeable) isosurfaces along flanks of the

The existence of a third anomaly to the south of the Kismet and CM targets, was believed to be
under basalt cover. However, through follow-up fieldwork, this area was found to be a large body

of quartz-diorite/tonalite. Currently the exposed MT corridor is 11 km in length and 4 km in width
and occurs along a NW trending axis. The exposure varies and can often be covered in a
moderate veneer of soil, which obscures the underlying geology; however, tonalite / diorite can
be mapped and linked in several areas, and an inference can be made on the underlying geology
between these areas. Basalt cover exists to the east and west of the MT corridor and can be
highlighted by intermediate to high-MT responses.
The tonalite-to-diorite is locally mineralized; however, these mineralized zones are currently
discrete. Large sections of the tonalite / diorite have been overprinted by tourmaline, which
replaces primary hornblende in the tonalite / diorite. The intensity of the tourmalinization increases
towards the NW, and Kismet. This overprinting pattern encourages the thesis of a large magmatic
hydrothermal event linked to the Kismet Breccia, or the large MT anomalies seen at depth.
Upcoming Catalysts
IDEX is advancing exploration at Freeze designed to generate steady news flow through the fall
and winter:
● KSMT25002 was completed to a depth of 422.70 m. Drill core has been processed and
assays are expected in October.
● KSMT25003 is currently in progress and is a 75 m step-out from hole KSMT25001. The
hole was drilled to the north and parallel to KSMT25002. At the time of writing the hole
has a current depth of 281.33 m.
● KSMT25004 is planned as a 150 m step-out from hole KSMT25001, and the drill
orientation is currently unconstrained.
● Field exploration at Freeze remains ongoing, with new drill targets identified and to be
disclosed in upcoming press releases.
Sample Analysis and QAQC
All drill core samples were prepped and analyzed at AGAT Labs Analytical in Calgary, Alberta,
and Thunder Bay, Ontario, an ISO 17025 and ISO 9001 certified laboratory. Samples were dried
and crushed to 2 mm, from which a 250 g sub-sample split was then pulverized to 85% passing
a 75 micron sieve. Following preparation, a 48 element 4-acid digestion (method 201-071) was
conducted. For this, a 0.25 g aliquot of the prepared pulp was digested in a 4-acid solution
consisting of hydrochloric, nitric, perchloric and hydrofluoric acids. 4-acid is a near total digest
and only the most highly resistant minerals are not dissolved. The resulting solution was analyzed
via ICP-OES and ICP-MS. Lower detection limits for this procedure are 0.01 ppm for silver, 0.5
ppm for copper and 0.05 ppm for Molybdenum.
Gold was analyzed by 202-051, a 30-gram fire assay fusion with AAS finish. No significant results
were reported.

Samples with initial results beyond the upper detection limit of the 201-071 method were analyzed
by over-limit 201-470 procedure (ICP-OES and/or ICP-MS) for Copper. For copper, the threshold
is >1%.
AGAT Labs Analytical employs internal quality control standards, duplicates and blank samples
at set frequencies. Blind certified reference materials (CRMs), blank samples and duplicate ¼
core samples were systematically inserted by the Company into the sample stream and analyzed
as part of the Company's quality assurance/quality control protocol.
