Power Metallic updates on first assays from summer drill program

TORONTO, CANADA (By Power Metallic, 22.Sep.2026, Words: 285) — Power Metallic Mines Inc. provided the first assays of extensional deep drilling of assay results from its summer 2026 drill program. 

Prior to the summer drill program drilling concentrated on improving the density of drill intercepts for the recently announced MRE to increase the confidence of modelling Lion, particularly within the range of a potential future open pit, and to bring the vast majority of the known deposit as of the end of the winter program (end Apr. 2026) to Drill Indicated category.

For the summer drill program Power Metallic has carried out widely spaced exploration drilling on geological and geophysical (EM) targets and more importantly begun a program of extending the Lion deposit to depth below the outline of the MRE model. The 2 holes reported here are the first assays to be completed on this deep drilling.

Hole PML-26-125 is the deepest assay results to date at Lion at a vertical depth of nearly 800m vertical depth, well below the current MRE. Prior to Hole PML-26-125 The deepest reported hole intersecting the core of the Lion shoot to date (PML-25-002) intersected 1.95m at 7.95% CuEqRec at approximately 610m vertical depth. 

This hole was targeted on the projected center of the Lion plunge approximately 150m below the previous deepest hole and intersected 5.7m of massive to semi-massive copper sulphides. 

An earlier drill hole, PML-26-121a targeted the western side of the projected plunge of Lion at a vertical depth of nearly 650 meters and intersected disseminated to semi-massive copper sulphides. 

A subsequent hole (PML-26-128) tested the eastern side of the interpreted Lion plunge at nearly 900m vertical depth, showing disseminated and massive veinlets of copper sulphides, with assays pending.
