INVENTUS COMMENCES 6,000-METRE, 155-HOLE PHASE 3 DRILL PROGRAM AT PARDO

Phase 3 drilling is under way at Inventus Mining Corp.'s 100-per-cent-owned Pardo (River of Gold) project near Sudbury, Ont. The approximately 6,000-metre, 155-hole program aims to test the extension of Pardo's multiple gold-bearing layers and expand the area tested by drilling from 1.2 square kilometres to 3.55 square kilometres. The program begins as Inventus advances its maiden mineral resource estimate, targeted for mid-November, 2026, providing an initial resource foundation to support its direct ship ore (DSO) plan while phase 3 drilling tests the broader scale of the gold system.

Highlights:

• Phase 3 drilling commenced on Oct. 14, 2026, with 155 drill holes planned for approximately 6,000 metres of drilling.
• The program aims to expand the area tested by drilling by approximately 196 per cent, from 1.2 square kilometres to 3.55 square kilometres.
• Stepout drilling will test the continuation of multiple gold-bearing conglomerate layers, including the sulphide-rich Matinenda conglomerate (MaC).
• Final phase 2 drill assays are being received, with the maiden mineral resource estimate targeted for mid-November, 2026.

Phase 3 drill program

The phase 3 drill program is designed to significantly expand the area tested by drilling at Pardo. Previous phase 1 and phase 2 drilling has intersected gold-bearing conglomerate throughout the existing 1.2-square-kilometre area. Phase 3 will test an additional 2.35 square kilometres of favourable geology, testing extensions of the Main layer and other prospective gold-bearing layers.

Matinenda conglomerate exploration

Phase 3 will also target an area of shallow sulphide-rich, gold-bearing Matinenda conglomerate (MaC) in the western part of the project. Historical drilling in 2009 intersected 7.13 metres grading 0.51 gram per tonne gold, including 2.13 metres grading 1.21 grams per tonne gold, beginning 11 metres below surface in drill hole PD-09-05.

Recent geological analysis has identified a strong positive correlation between visually estimated sulphide content and gold grade within the Matinenda conglomerate. Inventus will be evaluating whether the sulphide-rich material can be upgraded through ore sorting to produce a higher-grade gold-sulphide concentrate suitable for direct shipping to an existing processing facility.

The company is also investigating the potential value of a sulphide-gold concentrate for regional smelters. If successful, this opportunity could provide an additional development pathway at Pardo, complementing the company's advancing direct ship ore (DSO) strategy for the Main layer. Further testing and commercial evaluation are required to establish feasibility.

Maiden mineral resource estimate

Inventus is receiving the final phase 2 drill assay results, which will be incorporated into its maiden mineral resource estimate, targeted for completion in mid-November, 2026. This initial estimate will cover only the previously drilled area and is intended to provide a resource foundation for advancing the company's direct ship ore (DSO) plan. Meanwhile, phase 3 drilling will focus on expanding the known extent of gold mineralization, with the goal of supporting a potentially larger mineral resource estimate in the future.

Wesley Whymark, chief executive officer and director, commented: "Phase 3 is an important step toward understanding the full scale of the Pardo gold system. We have encountered gold-bearing conglomerate throughout the area drilled to date, and this program will test a significantly larger area across multiple layers. At the same time, the Matinenda presents an exciting opportunity to potentially develop a second DSO product alongside our more advanced Main layer. With our maiden resource estimate targeted for mid-November, we are advancing both the exploration potential and development opportunities at Pardo."

Next steps:

• Report the remaining phase 2 drilling assays;
• Complete the maiden resource estimate, targeted for mid-November, 2026;
• Advance phase 3 drilling and report results as available;
• Define the next stage of Matinenda metallurgical and ore-sorting test work;
• Advance plans to resume bulk sampling, with approximately 10,000 tonnes stockpiled and an additional 20,000 tonnes permitted for extraction;
• Continue working toward regulatory approval for tailings placement and evaluating additional long-term processing opportunities;
• Updates on the direct ship ore (DSO) advancements into 2027.
