IDEX Metals Receives USFS Approval & Provides Drilling Update for

Freeze Project, Idaho

Vancouver, B.C. – August 25, 2025 – IDEX Metals Corp. (“IDEX” or the “Company”) (TSXV:

IDEX; OTCQB: IDXMF) is pleased to announce that the U.S. Forest Service (“USFS”) has

approved the Company’s Plan of Operations under a Categorial Exclusion (“CE”) for expanded

exploration at its 100% owned Freeze Project, located in Washington County, Idaho, USA.

With the CE approval in place, IDEX is now positioned to advance exploration on its highly

prospective USFS claims that form the western part of the Freeze project. Anticipated work

programs include diamond drilling, ground-based geophysics, and expanded mapping and

sampling programs, all aimed at advancing the Company’s magmatic-hydrothermal copper-gold

model. This approval also allows for future drilling at the CM prospect, a large previously untested

target that will complement ongoing drilling at the Kismet area.

Clayton Fisher, CEO of IDEX Metals, commented: “We’re really pleased to have the green light

to drill CM. It’s a big target we’ve been eager to test and adding it to the program makes this

project even more exciting. With current drilling at Kismet, and the CM prospect now ready to go,

we have a real opportunity to show the scale of what is emerging at the Freeze Project.”

Drilling Update: Kismet Target

The 2025 drill program at the Kismet target was designed with two primary objectives: (1) to

confirm the sub-surface presence of a mineralized tourmaline-bearing breccia reported in

historical records (see June 10 th, 2025, news release ), and (2) to test at depth for a potential

causative porphyry source to the breccia.

IDEX has now completed the first drill hole (KSMT25001) of the 2025 season at the Kismet target.

KSMT25001 was designed to test and confirm the existence and extent of the tourmaline breccia

and associated intrusive lithologies documented at surface and in historical reports. Historical

drilling at the Kismet prospect from 1965 yielded an intercept of 41.15 m at 0.85% Cu from 9.14

m in Hole 4 (Table 1; June 10th, 2025, news release).

Hole KSMT25001 ended at a depth of 278 metres, which is over four times greater than the depth

of the historical hole drilled in 1965 (67.54 metres). Furthermore, KSMT25001 encountered both

2

oxide and sulfide mineralization throughout the length of the hole with varying degrees of intensity.

KSMT25001 ended in mineralization but had to be stopped due to technical drilling conditions,

with further drilling planned in follow-up holes. Core processing has now been completed, and the

samples have been submitted to AGAT Laboratories in Calgary, Alberta. Assay results from hole

KSMT25001 are expected in September.

The Company continues to advance drilling of the second hole at Kismet, KSMT25002. At the

time of writing, KSMT25002 has surpassed 404 metres depth and continues to encounter

mineralized intrusive and breccia units. Drilling remains ongoing, with assays expected in

October.

Geological Description

KSMT25001 was designed with the purpose of confirming the historical information encountered

in the tourmaline breccia drilled at Kismet in 1965. The Company is happy to report that hole

KSMT25001 has confirmed historical descriptions of lithology, mineralization and alteration.

The hole encountered mineralization from surface in the form of oxide minerals malachite and

chrysocolla, which occurs on fracture surfaces and replaces primary chalcopyrite in the matrix of

the tourmaline breccia / magmatic breccia system. The mineralization continues downhole with

zones of oxide-copper mineralization transitioning to more sulphide dominant (pyrite-chalcopyrite-

molybdenum) hydrothermal infill mineralization downhole. Oxide-copper mineralization continues

to occur at depths >200 metres along local structures.

The hole is characterized by a suite of intrusive rocks, varying from gabbro to diorite to

granodiorite in composition. The units have a complex geological interrelationship but often form

the host rocks and clasts contained in intervals of magmatic breccia. The magmatic breccia

system has been variably overprinted by variably mineralized hydrothermal fluids, including a

tourmaline-magnetite (hematite)-pyrite-chalcopyrite assemblage that acts as infill to, or entirely

overprints the system. There are intermittent zones of silicified intrusive that appear to pre-date

the brecciation event; however, the relative timing of emplacement, brecciation and mineralization

and subsequent faulting of all units at Kismet is not currently constrained. Additional drilling along

and parallel to section is anticipated to aid in this interpretation.

The hole was stopped at a depth of 278 metres within a mineralized interval of breccia with

fracture coating oxide copper minerals, malachite and chrysocolla. Drilling was terminated due to

circulation loss and challenging ground conditions; however, the hole successfully confirmed

mineralization at depth and remains open for follow up drilling.
