Irruptive Metals drills 795.2 m grading 0.66% CuEq

Complete results from first drillholes campaign with significant Copper-Gold Mineralization at Pimentón Project

2026 Diamond Drilling Program Confirms and Extends Historical Copper-Gold Mineralization; Drilling Completed 3,084 m Across Four Holes.

Toronto, Ontario--(Newsfile Corp. - August 20, 2026) - Irruptive Metals Corp. (TSXV: IRR) (" Irruptive Metals " or the " Company "), an emerging copper-gold exploration company advancing the high-potential Pimentón Project located in the V Region, Central Chile, is pleased to announce the completion of its first diamond drill campaign, totalling 3,084 metres across four drillholes (IMP001 to IMP004), designed to test the central Cu-Au porphyry system within the Company's flagship project. All assay results have now been received, validated, and incorporated into the geological model.

Drill Program Highlights

IMP002 returned 795.2 m with 0.66% CuEq (0.41 g/t Au, 0.31% Cu) from 167 m to end of hole at 962.2 m, including a gold-dominant high-grade interval of 60 m grading 1.49% CuEq (1.37 g/t Au, 0.31% Cu)

IMP001 returned two significant intervals: 202 m with 0.38% CuEq (0.22 g/t Au, 0.19% Cu) from 177 m to 379 m, and 358.4 m with 0.49% CuEq (0.29 g/t Au, 0.24% Cu) from 513 m to 871.4 m (EOH)

IMP003 returned 42 m with 0.25% CuEq (0.12 g/t Au, 0.15% Cu) from 171 m to 213 m and 176 m with 0.31% CuEq (0.15 g/t Au, 0.18% Cu) from 227 m to 403 m

IMP004 returned 406 m with 0.47% CuEq (0.26 g/t Au, 0.25% Cu) from 259 m to 665 m.

Results confirm and extend historical drilling by Rio Tinto and Anglo American, demonstrating geological continuity across the Central target area

Drill program completed 3,084 m of drilling across four holes from two platforms, with operations concluded on April 17, 2026

"These results from our 2026 drilling program are highly encouraging and confirm the significant copper-gold potential at Pimentón," said Alfredo Bazo, President and
