IDEX Identifies Multiple Porphyry Targets at Freeze Project with Final Drill Results and

Integrated Geophysics

Vancouver, B.C. – February 25th, 2026: IDEX Metals Corp. (“ IDEX” or the “ Company”) (TSXV: IDEX;

OTCQB: IDXMF) is pleased to report final assay results from drill holes KSMT25005 and KSMT25006

at its 100% -owned Freeze Copper -Gold-Molybdenum Project in Idaho, USA (“Freeze”, or the

“Property”). The 2025 drill program succeeded in confirming continuous mineralization across the

Kismet Breccia Complex (“Kismet”), with each of the campaign’s six drill holes intersecting

significant copper.

Drilling demonstrated that the Freeze system extends from a surface-exposed tourmaline breccia

complex into deeper intrusive -hosted mineralization. Notably, drill hole KSMT25006 intersected

intrusive-hosted copper-molybdenum mineralization, following the penetration of a pyrite-rich shell,

representing a key geological transition within the system. Increasing molybdenum grades and

molybdenite-chalcopyrite-bearing vein networks occurring towards the bottom of the hole – strong

geochemical vectors – suggest proximity to a deeper magmatic-hydrothermal source.

These geological observations are supported by newly -acquired induced polarization (IP) and

Magnetotelluric/Extremely Low Frequency (MT/ELF) geophysical data, which define a large,

coherent conductivity anomaly at depth beneath the Kismet and North Breccia trend; this represents

a priority porphyry target to begin drilling in 2026.

Exploration Highlights

• KSMT25005 intersected 87.03 m of 0.36% CuEq (0.285% Cu, 2.04 g/t Ag, 57 ppm Mo), within

287.43 m of 0.27% CuEq (0.19% Cu, 1.27 g/t Ag, 72 ppm Mo)

• KSMT25006 intersected 1 09.80 m of 0. 54% CuEq (0.12% Cu, 0.65 g/t Ag, 517 ppm Mo),

within 428.55 m of 0.278% CuEq (0.12% Cu, 0.68 g/t Ag, 186 ppm Mo)

• Largest intersection of intrusive-hosted copper–molybdenum mineralization to date, in drill

hole KSMT25006, following penetration of a pyrite-rich shell

• Strong molybdenum enrichment and molybdenite veining at depth , supporting vectoring

towards a magmatic-hydrothermal source

• IP and MT/ELF geophysics define a large conductivity anomaly at depth , directly beneath

Kismet and the North Breccia

• Expanded Phase II drill program set to begin Spring 2026, designed to expand the resource

through the Kismet Corridor (Kismet>North Breccia>Frostfall), along with exploratory drilling

at the CM, Olive Creek, and Devils Slide targets

• First, drill-ready target defined for 2026 , stepping onto the North Breccia and testing the

center of the geophysical anomaly

Clayton Fisher, CEO of IDEX Metals Corp. commented, “Our 2025 drill program clearly demonstrated

the consistent presence of copper mineralization from surface to depth across an emerging porphyry

prospect at Freeze. We have two tourmaline breccias exposed at surface, copper mineralization in all six

drill holes completed to date, and — critically — we’ve now intersected intrusive -hosted copper -

molybdenum mineralization, after drilling through a pyrite shell in hole KSMT25006.”

“The increasing molybdenum grades and molybdenite veining at the bottom of that hole provided

exactly the kind of geological indicators we want to see as we vector towards a deeper magmatic source.

When we overlay that data with our IP and MT/ELF geophysics – which define a large conductivity

anomaly directly below Kismet and the North Breccia – the picture becomes very compelling. In 2026, we

plan to step out onto the North Breccia and drill straight down into the heart of that anomaly.”

KSMT25005

Drill hole KSMT25005 was drilled off the same pad as KSMT25001 and KSMT25002 but oriented at

an azimuth of 45 degrees , to evaluate the eastern extent of the Kismet Breccia Complex. The hole

was completed to a depth of 287.43 metres. KSMT25005 was c ollared in the same breccia unit

encountered at the top of all previous holes, consisting of a clast -supported breccia hosting oxide

copper mineralization derived from the alteration of primary chalcopyrite with rare bornite. Copper

mineralization is strongest near surface and becomes variable downhole.

The breccia matrix is dominated by a distinctive tourmaline -bearing monzonite that brecciates

porphyritic granodiorite. This monzonite contains abundant 0.5 –1 cm acicular tourmaline and

represents a late -stage intrusive phase that can be correlated across all drill holes completed to

date. Toward s the end of the hole, a sequence of tourmaline -bearing intrusive pulses and

hydrothermal fluids overprints an earlier tonalite phase, accompanied by magnetite, tourmaline, and

pyrite. These features indicate a sust ained and evolving hydrothermal system along the eastern

margin of the breccia complex.

KSMT25006

Drill hole KSMT25006 was the final hole completed during the 2025 exploration campaign at the

Property. The hole was collared approximately 340 metres north of drill holes KSMT25001,

KSMT25002, and KSMT25005, and was drilled at an azimuth of 340 degrees to a total depth of

428.55 metres. The primary objectives of KSMT25006 were to test the northern extent of the Kismet

Breccia Complex, evaluate its potential connection to the North Breccia Zone (as referenced in a

previous news release), and assess the structural and mineralogical relationship with Hornet Creek,

which is interpreted to represent a m ajor control on mineralization across the Freeze Property.

Drilling was terminated due to challenging weather conditions, access, drill suitability and safety

considerations.

Alteration & D-Vein Stockwork

KSMT25006 intersected a magmatic breccia sequence at surface, characterized by a monzonitic

matrix containing clasts of porphyritic granodiorite and alternating between clast -supported and

matrix-supported textures consistent with breccias observed elsewhe re on the Property. At depth,

the hole transitioned into porphyritic granodiorite that is strongly overprinted by quartz -sericite-

pyrite alteration, including D -type pyrite veins and quartz -pyrite-molybdenite-chalcopyrite vein

networks. This interval repr esented the first occurrence of well -developed vein -hosted

mineralization encountered during the drill program and is interpreted to form part of a pyrite -rich

shell associated with an underlying magmatic-hydrothermal system.

Integrated evaluation of lithology, alteration, and geochemistry at the bottom of KSMT25006

indicates a vector towards a potential heat source, highlighted by increasing molybdenum values (as

molybdenite) and the development of localized potassic alteration overprinted by phyllic alteration.

These observations, when considered alongside newly -acquired geophysical data, support the

interpretation that a deeper, mineralized magmatic-hydrothermal system may be present within the

broader Kismet corridor.

Induced Polarization (IP) Survey

Figure 4: IP Results, High Chargeability Feature Trending NW Along the Kismet Corridor

IP was completed during the 2025 season by Moombarriga Geoscience Pty. LT totalling 4.8 line-km.

The IP was targeting the zone between the North Breccia Target and the Olive Creek drainages. The

IP reveals several conceptual targets that will be followed up on during the 2026 exploration

campaign.

At Kismet, IP data define a broad, mildly -chargeable and moderately -resistive feature spatially

coincident with the Kismet tourmaline breccia complex. This feature occurs outboard of a distinct,

highly-chargeable and highly -resistive anomaly that extends northward from Kismet toward the

North Breccia. The Hornet –North Breccia anomaly is spatially coincident with a pyrite -rich shell

intersected in drill hole KSMT25006 and is interpreted to represent the flank of a magmatic -

hydrothermal system.

Figure 5: IP Results (Figure 4, Cross Section B-B')

The Olive anomaly is defined as a focused zone of elevated chargeability within a moderately -

resistive host, consistent with a discrete and vertically-continuous subsurface feature. The continuity

and geometry of the anomaly are interpreted to suggest a localized structural conduit or a vertically-

continuous intrusive feature. Its position outboard of the Kismet complex and the Hornet –North

Breccia system highlights it as a prospective target where in sulfide mineralization may be spatially

concentrated along a structural corridor. Field reconnaissance indicates that the area is covered by

Tertiary basalt flows, which mask the interpreted lithologies at depth. The Olive target is therefore

considered to warrant follow -up drilling to test its depth extent and relationship to known

mineralized zones.

The southeasternmost portion of the IP section is characterized by a zone of elevated resistivity with

minimal associated chargeability. This anomaly is currently unconstrained but spatially coincides

with mapped diorite intrusive rocks with localized tourmaline development, sodic–calcic alteration,

and zones of autobrecciation. The geophysical response defines a coherent and laterally-continuous

zone that is distinct from the chargeable features observed to the northwest. Additional fieldwork

will aim to further constrain the relationship between the IP and lithological characteristics within

this zone.

Magnetotelluric (MT) and Extremely Low Frequency (ELF) Surveys

Figure 6: MT & ELF Results with 2026 Drill Targets

In 2025, IDEX completed a joint Magnetotelluric (MT) and Extremely Low Frequency (ELF) survey

covering large parts of the Freeze Property, with a particular focus on the Kismet Breccia Complex

and the surrounding mineralized corridor. The survey produced a Property-wide resistivity and

conductivity dataset that has since been inverted and reprocessed. The results continue to outline a

large and coherent geophysical system centered on the Kismet corridor.

In the immediate vicinity of the Kismet breccia pipe, the resistivity model defines a shallow, localized

zone of relatively weak resistivity (~400 ohm -m) that is limited in vertical extent. This shallow

response is spatially associated with – but offset from – a deeper zone of moderate conductivity

developed beneath and adjacent to the breccia. This geometry is consistent with the Company’s

interpretation of Kismet as a shallow expression of a deeper magmatic -hydrothermal system, with
