IDEX Metals Outlines Four Broad Chargeability Targets Across 91.45 Line-Kilometre IP Survey
at the Freeze Copper Project, Idaho, USA
Vancouver, British Columbia: August 11, 2026 - IDEX Metals Corporation (“ IDEX” or the “ Company”) is
pleased to announce the results of a 91.45 line-kilometre induced polarization (“IP”) survey completed on
its 31,645 acre Freeze Project in Washington County, Idaho. The survey was carried out by TMC
Geophysics between April 1 and June 11, 2026, and has been integrated with IP data acquired over the
same ground by Dias Geophysics in 2024 and Moombarriga Geophysics in 2025 to produce a merged
three-dimensional resistivity and chargeability model extending to approximately 600 metres below
surface.
Highlights
• 91.45 line-kilometres of pole-dipole IP acquired along 27 lines, with individual line lengths of 2.0 to
6.25 kilometres and effective penetration to approximately 275 to 550 metres depending on
electrode spacing.
• Four broad anomalous corridors each traced over approximately 1.1 to 1.6 kilometres of strike,
spatially associated with the Shiver, Kismet, North Breccia and CM targets.
• Anomalies correlate with known porphyry-style alteration and mineralization drilled in 2025 and
2026.
• Chargeability and resistivity zonation consistent with a porphyry system, the survey has outlined a
district-scale polarizable footprint with an inner low-chargeability, elevated-resistivity domain
flanked by a strongly polarizable halo, a pattern typical of zoned porphyry systems. The corridors
remain open in several directions.
• Copper, molybdenum and tungsten occurring at both priority targets: 2026 drilling has encountered
visually logged chalcopyrite, molybdenite and tungsten at North Breccia — an 800-metre step-out
north from 2025 drilling — while Kismet drilling continues to expand copper oxide mineralization,
including an 80-metre step-out west, that extends the known oxide zone laterally and at depth.
“This is a huge moment for Freeze." said Clayton Fisher, CEO of IDEX Metals. "The IP survey has
connected the dots across the project and shown us that we’re not looking at one isolated target —
we’re looking at a much larger system with four major chargeability corridors and several targets still
open.
Target A is the one we’re most focused on right now. It sits between Kismet and North Breccia, where
we already have copper, molybdenum and tungsten in the system, and it gives us a clear drill target in
the heart of our highest-priority area.
We have drills turning, assays pending, and a growing list of targets across the property. This is exactly
why we expanded the 2026 program — Freeze has scale, it has momentum, and we believe we’re just
getting started.”
IP Survey

IDEX completed 91.45 line-kilometres of pole-dipole induced polarization over the northwestern portion
of the Freeze Project between April 1 and June 11, 2026, carried out by TMC Geophysics. The survey
comprised twenty-seven lines in two orthogonal sets, allowing polarizable features to be traced in two
directions rather than inferred from a single orientation: thirteen lines, oriented NW/SE, ranging from
3.10 to 6.25 kilometres in length and totalling 63.45 line-kilometres, and fourteen lines, oriented NE/SW,
at 2.00 kilometres each, totalling 28.00 line-kilometres. Core coverage was acquired at 200 metre line
spacing across the highest-priority ground from L-3800N through L-5600N, widening to 400 metres to the
north, with the cross-cutting set averaging approximately 250 metre spacing across the main block and a
wider-spaced group of four reconnaissance lines to the south.
The 2026 data were merged with induced polarization surveys completed by Dias Geophysics in 2024 and
Moombarriga Geophysics in 2025 and inverted as a single three-dimensional dataset extending to
approximately 600 metres below surface, giving continuous coverage across the three campaigns.
Depth of investigation varies with electrode spacing and line orientation. Resolution of the inversion
decreases with depth, and features imaged below approximately 450 metres are less well constrained,
particularly on the wider-spaced lines.

Target A
Target A is a broad, moderate to strong polarizable response in the east-central grid, trending northeast-
southwest over approximately 1.3 kilometres. The anomaly appears to sub-outcrop to the south (at the
North Breccia and Kismet) and deepens rapidly to the north. Target A is believed to be related to
mineralization and/or alteration associated with the North Breccia and Kismet targets.
Target A is the Company’s highest-priority target and is currently being drilled on both flanks of the
anomaly. The chargeability pattern at the margins of Target A is characteristic of the pyrite halo that
typically envelops a porphyry centre, and the copper, molybdenum and tungsten mineralization logged in
the 2026 core are consistent with a magmatic hydrothermal metal assemblage. Drilling will subsequently
trace the chargeability feature to the north to define the relationship between chargeability, resistivity
and mineralization.
Target B
Target B occupies the northeast of the survey area and comprises a broad, moderate to strong polarizable
response trending north-south over approximately 1.1 kilometres, locally coincident with a slight
resistivity decrease. The source is better defined below 250 metres of vertical depth and appears to
deepen westward. Target B is coincident with a broadscale copper-in-soils anomaly in the north of the
anomaly at the Shiver target and may reflect mineralization associated with deeply seated intrusions
largely covered by tertiary basalt.
Permitting for this target is in progress and IDEX anticipates receiving approval by the end of August 2026.
Target C
Target C covers the west-central grid and is defined by a broad, moderate to very strong response trending
northeast-southwest over approximately 1.3 kilometres. The anomaly widens markedly to the south,
where sources may also extend along northwest-southeast trends, and is locally shallow-seated in the
west.
Permitting for this target is in progress and IDEX anticipates receiving approval by the end of August 2026.
Target D
Target D in the northwest of the survey area, comprises a cluster of closely spaced moderate to very
strong polarizable anomalies trending northeast-southwest over approximately 1.6 kilometres and
remaining open to the northeast. Sources are generally better defined below 150 to 200 metres of vertical
depth. Target D may reflect mineralization (copper and gold) associated with the CM target. This portion
of the survey was completed by Dias Geoscience in 2024. This target is fully permitted.
Porphyry Potential
Taken together, the merged 2024 to 2026 inversion outlines a coherent, district-scale polarizable system
across the northwestern Freeze Project. The four corridors are individually 1.1 to 1.6 kilometres in strike
length, several remain open, and the strongest responses persist to the base of the reliably imaged model,
indicating the sources are not confined to near-surface cover. At Target A the chargeability halo, its spatial
coincidence with the pyrite intersected in drilling, and the copper-molybdenum-tungsten assemblage
logged in core together provide a coherent vector toward an interpreted porphyry centre to the east.
IDEX considers the Freeze Project to have the scale and zonation characteristics of a porphyry copper-
molybdenum-gold system and intends to test that interpretation directly with the current and planned
drill programs.

2026 Drilling Update

North Breccia
Drilling has commenced at North Breccia, with holes KSMT26-007, KSMT26-008 & KSMT26-011 having
been completed. The holes have intersected chalcopyrite, molybdenite, and tungsten mineralization has
been identified in the drill core by visual logging. The first drillholes were designed to test outcropping
mineralization at the North Breccia which is believed to be related to or a continuation of mineralization
encountered at the Kismet Breccia complex.
For the next hole, the Company will step out 800 m to the east to test the core of the chargeability high
at Target A and its relationship to mineralization in holes KSMT25-006, KSMT26-007, KSMT26-008,
KSMT26-009, KSMT26-010 and KSMT26-011. This collar location will allow the Company to test multiple
geological hypotheses related to the high chargeability feature at Target A. It will also allow IDEX to test
the anomaly to depth and in multiple directions including to the N-NW and S-SE.
The goal of the next series of drillholes will be to provide further information on the correlation between
high chargeability features and potential magmatic-hydrothermal alteration and mineralization.
Assays are currently pending for holes KSMT26-007 and KSMT26-008.
