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.

Irruptive Metals Corp. (TSX-V: IRR) 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 CEO of Irruptive Metals. “The consistency of our results with historical drilling by Rio Tinto and Anglo American validates our geological model. We are particularly pleased with the 795-metre intercept in IMP002, which demonstrates both the scale and grade potential of the Central target. We look forward to advancing the project toward resource definition as we prepare for our next drilling campaign, as the mineralization remains open.”

Program Overview and Results

The 2026 diamond drilling program was designed to twin or near-twin historical drillholes completed by Rio Tinto and Anglo American, with the objective of confirming historical geological and grade information and testing lateral and vertical extensions of known mineralization. The historical datasets were reviewed by Román Flores, P.Geo., author of the Company’s NI 43-101 Technical Report on the Pimentón Project (effective July 20, 2026). Mr. Flores is independent of Irruptive Metals for the purposes of Section 1.5 of National Instrument 43-101 and is a Qualified Person under NI 43-101.

Results obtained to date are consistent with the historical datasets and support the reliability of the original drilling. No mineral resource or mineral reserve has been estimated on the Pimentón Project, and the mineralization described in this news release is not necessarily indicative of the presence of a mineral resource or mineral reserve.

Using the same drill platforms as holes IMP001 and IMP002, IRR completed two additional holes (IMP003 and IMP004) oriented to the south (azimuth 180°, dip -70°) to evaluate the potential southward extension of the mineralized system. Hole IMP004 successfully intersected the targeted Cu-Au porphyry mineralization, including vein styles, sulfide assemblages and alteration consistent with the mineralized center defined in IMP001 and IMP002. These results provide additional evidence that the porphyry system remains open to the southeast, east and northeast supporting continued step-out drilling in that direction.

Mineralization is associated with a complex of Cu-Au porphyry dykes exhibiting potassic alteration (K-feldspar, biotite), EB-type and A-type veins. Higher-grade zones correspond to early mineral porphyry phases overprinted by green-sericite-chalcopyrite assemblages. Some High-sulfidation Au-Ag-Cu vein systems appear telescoped over porphyry and also located peripheral to the center.

The geological interpretation, based on the integration of new drillholes and historical datasets, identifies a Cu-Au porphyry dyke complex with an NNE orientation and near-vertical dip. This Cu-Au porphyry corridor is currently 600 metres long, 300 metres wide and is open to the E, SE, NE and W, representing the principal conduit for mineralization within the Central Target. The geometry and orientation of these dykes provide a coherent framework that explains the distribution of potassic-centred mineralization, the green sericite high-grade transitional halo, and peripheral alteration zones observed across both historical and recent drilling.

Outlook and Next Steps

• Reprocessing of historical geophysics (Magnetometry, IP-Res & MT) to improve and prioritize targets, Q3-2026
• Conduct geometallurgical sampling and mineralogical/metallurgical test work
• Resampling historical holes in central target (PP18 & PP04) to include in updated NI 43-101 Technical Report with initial inferred resource estimate, Q1-2027
• Advance drilling to test lateral and deep extensions of the Central target to expand the initial resources, Q4 2026 to Q1 2027
• Obtain the environmental permits (DIA) to drill the Ridge-Bx, SE, Verde and Maria Elena targets to consolidate the Pimentón project as a high-potential Cu-Au resource, Q1 2028

Table 1: Summary of Significant Drill Intercepts

Notes: Intervals are reported using a cut-off of CuEq >0.2% with three dilution samples (6 m) and no top-cut applied. CuEq = Cu% + (Au g/t × 0.86). Metal prices used are the two-year average (2024-2025): US$4.95/lb Cu and US$2,918/oz Au. Recoveries were assumed equal for all metals. CuEq is used for comparison purposes only. No metallurgical recovery testwork has been completed on the Project; equal recoveries have been assumed for all metals for illustrative purposes only, so the reported CuEq values may not be representative of recoverable or economically recoverable metal.

Reconciliation with Technical Report: These results are final and, where they differ, update the preliminary intercepts disclosed in the NI 43-101 Technical Report (July 20, 2026). Intervals in this release are composited using three dilution samples (6 m); the Technical Report used two dilution samples. Reported intervals are therefore not directly comparable to that report, and the 478 m at 0.80% CuEq interval shown for IMP002 in the Technical Report is not reproduced here.

True Widths: All reported intervals are downhole core lengths. True widths have not yet been determined and are expected to be less than the reported downhole lengths.

Sampling and QA/QC

Drill core was logged, sampled, and cut under the supervision of Company geologists. Samples were prepared and analyzed by AGS-Cotecna laboratory, which is independent of the Company and an ISO/IEC 17025-accredited laboratory. Gold assays were completed using fire assay with AAS finish. Multi-element determination was completed by four-acid digestion (HF-HNO₃-HClO₄-HCl) followed by ICP-OES analysis. The Company maintains a rigorous QA/QC program including the insertion of certified reference materials (5%), blanks (2.5%), and field duplicates (2.5%) at regular intervals. No material QA/QC issues were identified in the reviewed data. The Qualified Person has verified the data underlying the technical information disclosed in this news release, including by reviewing the assay results, the QA/QC data and the sampling and analytical procedures, and is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data.
