IDEX Metals Reports Integrated 2025 Soil Geochemistry Exploration Results, Freeze Property, Idaho

(TheNewswire)

Vancouver, B.C., March 25, 2026 –TheNewswire – IDEX Metals Corp.(“IDEX” or the “Company”) (TSXV: IDEX; OTCQB:IDXMF)is pleased to report results from its 2025 Freeze Property(“Freeze”, or the “Property”) soil geochemistry programlocated in Idaho, USA. The program has defined a cohesive,multi-kilometre hydrothermal footprint consistent with anintrusive-centered porphyry copper-molybdenum system. When combinedwith drill results and geophysical data acquired during the 2025exploration season, the soil geochemistry completes amulti-disciplinary dataset strongly inferring the presence of a buriedintrusive centre beneath the North Breccia-Kismet Corridor.

Highlights

Soil geochemistry suggests a buriedintrusive centre under the North Breccia-Kismet Corridor:

• Molybdenum at the core of the NorthBreccia-Kismet Corridor: a concentratedmolybdenum anomaly approximately 700 to 900 m in length is expressedat surface along the North Breccia-Kismet Corridor, representing thestrongest and most reliable indicator of proximity to a mineralizedburied intrusion 

• Tellurium confirms thehigh-temperature signal: tellurium enrichmentoverlaps the molybdenum core at North Breccia and western Kismet,providing a significant vector towards a high temperaturesource 

• Copper wraps around the core:elevated copper values form a shell around theanomalous molybdenum domain across a width of 400 to 700 m. Thiscopper halo is also coincident with tourmaline-copper breccia showingslocally, and a broader dispersal pattern 

• Metal ratios vector inward to thesource: copper-to-molybdenum ratios are lowestdirectly over the center of the Kismet target and increaseprogressively outward, pointing to a single buried intrusive centerbeneath the North Breccia 

Soil geochemistry, drill results, andgeophysics converge at the North Breccia:

• Three independentdatasets all lead the Company to the sameconclusion: the highest-priority target lies beneath the North Brecciaand immediate drill testing is required 

2026 exploration season set tocommence April 2026:

• Induced Polarization survey isexpected to begin in early April 2026, with the Phase II Drill Program to follow inlate April to early May. 

CEO Clayton Fisher, commented, “The 2025 program atFreeze has given us a very clear picture of the potential mineralizedsystem within the Kismet Corridor. Soil geochemistry has nowcorroborated what lithological observations in drilling andoverlapping geophysical anomalies (both MT and IP) were telling us: wehave a potential buried mineralized intrusive in our sights at NorthBreccia. We’re approaching the 2026 drill season with excitement andincreased confidence that the Kismet Corridor – and especially theNorth Breccia – will deliver the goods for IDEX.”

Soil Geochemistry at theKismet Corridor

Results from the 2025 soil survey reveal aconcentrically zoned metal system centered on the North Breccia andKismet Corridor. Molybdenum and tellurium define the innermost zone,potentially marking the highest temperature and most proximalexpression of a magmatic-hydrothermal system. Surrounding the Mo-Tecore is a broader Cu shell, beyond which lies an envelope of tungstenand bismuth that establishes the outer region of hydrothermalinfluence. This progression from core to halo – all centered on theKismet Corridor – is a typical pattern associated with buriedmineralized intrusive systems.

The copper-to-molybdenum ratio map reinforces theCompany’s interpretation. Ratios are at their lowest directly overthe North Breccia and Kismet core (where molybdenum dominates) andincrease progressively outwards in all directions. This concentricgradient is consistent and systematic, possibly indicating a buriedintrusion and mineralization source at the Kismet and North Brecciasystems.

The geochemical surface expression at Kismet issignificant in its implications regarding target depth. Molybdenum andtellurium are high-temperature indicators that sit near the top of theporphyry zonation sequence. Their presence and strength at surface(Mo: 2-6 ppm; Te >0.5 ppm) imply that the erosion level at Kismetintersects the upper portion of the system rather than its roots. Thisis highly significant in that the majority of the porphyry system – including its upper portions –could remain preserved and uneroded.

Integrated Soil and GeophysicalInterpretation

The soil geochemistry findings are directly supportedby magnetotelluric (MT), and Vector IP data geophysical data acquiredacross the Freeze Property during the 2025 field season (see February25th,2026, news release). The KismetBreccia Complex itself produces a relatively resistive geophysicalresponse at surface, consistent with the tourmaline-bearing brecciaand oxide copper mineralization encountered in relatively shallowdrilling.

Beneath the Kismet breccia, the MT inversion defines alarge conductive zone at moderate depth corresponding to a pyrite-richshell. This interpretation was directly validated by drill holeKSMT25006, which penetrated the breccia and intersected the pyriteshell, with coincident quartz-sericite-pyrite alteration at depth andthe first instances of elevated molybdenum andmolybdenite-chalcopyrite vein networks.

The property-wide MT data also defines a large, highlyconductive body at approximately 800 m depth directly beneath theNorth Breccia trend, with resistivity values in the 100 to 200 ohm-mrange. This deep conductor sits precisely below the broad molybdenumand tellurium core defined by the soil survey and has not yet beentested by drilling. Its size, depth, and alignment with the KismetCorridor, elevate the North Breccia to the primary drill target of the2026 exploration season.

The convergence of vectors from three independentdatasets at the Kismet Corridor is the most compelling takeaway fromthe 2025 exploration program. The soil geochemistry identifies theNorth Breccia and Kismet Corridor as the highest-priority drilltargets, with molybdenum, tellurium, and metal ratio gradients allpointing inward to the same theorized buried intrusive body. The drillresults from KSMT25006 confirm the existence of a developed pyriteshell with increasing molybdenum and molybdenite veining at depth. TheMT geophysics defines a large transitional conductive response from300-800 m beneath the same corridor. Each dataset was acquired andinterpreted independently. All three point to the same target beneaththe North Breccia and Kismet Corridor.

2026 Exploration Season

IDEX’s 2026 exploration season is scheduled to commence in earlyApril 2026 with an expanded Induced Polarization survey across theKismet Corridor to better define near-surface structures and improvethe efficiency and accuracy of drill targeting, followed by drillingat the North Breccia porphyry target in late April to early May. Thecompany also anticipates continuing with generative surfaceexploration, which includes mapping and soil & rock samplingacross the remaining unexplored areas of the project.

Sample Analysis and QAQC

Rock and Soil samples taken during the 2025 program were prepped andanalyzed in Calgary, Alberta and Thunder Bay, Ontario, by AGAT LabsAnalytical, an ISO 17025 and ISO 9001 certified laboratory. Soilsamples were dried and screened to 180 micron mesh, followed byassaying via method 201-074, a 51-element aqua regia digestion methodwith an ICP-OES/MS finish. Rock samples were crushed to 2 mm, fromwhich a 250 g split was further pulverized to 85% passing a 75 micronsieve. Following preparation, a 30 g sample was analyzed by method202-051 with a 30 g sample being analyzed by fire assay with an AASfinish. Multi-element assays for rocks were determined by method202-071 where a 0.25 g aliquot was digested in a 4-acid solution andanalyzed by ICP-OES/MS. Samples with initial results beyond the upperdetection limit of the 201-071 method were further analyzed byover-limit 201-470 procedure (ICP-OES and/or ICP-MS). For copper, thethreshold is >1%. AGAT Labs Analytical employs internal qualitycontrol standards, duplicates and blank samples at set frequencies.Blind certified reference material (CRM), blank and standard sampleswere also systematically inserted by the Company into the samplestream and analyzed as part of the Company's qualityassurance/quality control protocol.
