IDEX Metals Intersects Significant Copper Mineralization at Freeze Property

Vancouver, B.C. — September 10, 2025 — Leads & Copy — IDEX Metals Corp. (TSXV: IDEX; OTCQB: IDXMF) has announced its first drillhole on the Freeze property intersected 182.25 m of 0.32% Cu from the surface. The drill hole, KSMT25001, intersected variable intervals of oxide copper mineralization beginning at 1.5 metres downhole.

The company said KSMT25001 targeted 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.

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 targetsacross the broader Freeze Project area, setting the stage for a pipeline of future drill testing.

Clayton Fisher, CEO of IDEX Metals, said hole KSMT25001 has confirmed a mineralized breccia and delivered continuous copper mineralization over its entire length. He said the result highlights the potential of the Freeze property and the Idaho Copper Belt to host large, near-surface copper mineralization.
