Inventus Expands Shallow Gold Mineralization and Advances Bulk Sampling at The Pardo River of Gold Project

TORONTO, ON / ACCESS Newswire / May 27, 2026 / Inventus Mining Corp. (TSXV:IVS) ("Inventus" or the "Company") is pleased to report additional assay results from its ongoing Phase 2 drill program and provide an update on its bulk sampling program at the 100%-owned Pardo "River of Gold" Project, located 65 km northeast of Sudbury, Ontario.

HIGHLIGHTS

• Phase 2 drilling of the Matinenda Layer returned highlight intersections of:

  • 0.65 g/t gold over 6.53 m, including 1.10g/t gold over 3.00 m (PD-26-280)

  • 0.52 g/t gold over 7.19 m, including 1.03g/t gold over 2.00 m (PD-26-277)

  • 0.68 g/t gold over 4.98 m, including 1.76g/t gold over 0.40 m (PD-26-278)

BULK SAMPLE AND GRADE-CONTROL DRILLING UPDATE

Processing of the remaining 7,500 tonnes from the 10,000-tonne Trench 1 bulk sample is currently underway, with results expected in June. The first 2,512 tonnes processed earlier this year returned 172 ounces of gold, generating gold sales of $1.17 million and exceeding bulk sample costs by 102% (see news release dated March 18, 2026).

The Company has also extracted an additional 10,000-tonne bulk sample, which is pending processing.

The Company completed 28 additional grade-control holes, with assay highlights reported in Table 1 and drill hole details in Table 4. These holes intersected the flat-lying mineralized Main Layer within 12 metres of surface west of the Trench 1 bulk sample site. These drill results will guide extraction of the remaining 20,000 tonnes of permitted bulk sample material.

PHASE 2 DRILLING UPDATE

The Phase 2 drilling program resumed on May 21, 2026, following the spring melt. The Company plans to mobilize a second drill in mid-June to accelerate drilling in support of the planned maiden resource estimate in Q4 2026. The current 7,000-metre drill program is designed to expand and confirm continuity of the Main, Matinenda and Upper Conglomerate layers.

Main Layer

Phase 2 drilling of the Main Layer continues to expand and define the mineralized footprint at Pardo, confirming gold mineralization across additional near-surface drill holes and supporting the Company's interpretation of a laterally extensive, flat-lying conglomerate-hosted gold system. The latest results extend the drilled coverage of the Main Layer and provide important new data for the planned maiden resource estimate. The location of the reported Main Layer results is shown in Figure 1, highlight assay intersections are summarized in Table 2, and drill hole location details are provided in Table 4.

Key results include 5.14 g/t gold over 2.33 m, including 15.99 g/t gold over 0.70 m in TR2-26-04; 3.46 g/t gold over 1.22 m, including 12.24 g/t gold over 0.30 m in PD-26-263; and broader intervals such as 0.39 g/t gold over 10.50 m in PD-26-249 and 0.33 g/t gold over 12.32 m in PD-26-247. These results add further support for the Main Layer as a laterally extensive, near-surface, flat-lying mineralized horizon and provide additional data for the planned maiden resource estimate.

Matinenda Layer

Initial Phase 2 drilling results from the Matinenda Layer returned thick intervals of gold mineralization (see Table 3), including 0.65 g/t gold over 6.53 m in PD-26-280, 0.52 g/t gold over 7.19 m in PD-26-277 and 0.68 g/t gold over 4.98 m in PD-26-278. These holes are located west of the Main Layer area and show that mineralization is present in a separate, flat-lying conglomerate horizon (Figure 2).

These initial Matinenda results are significant because they demonstrate gold mineralization in a separate, flat-lying conglomerate horizon west of the Main Layer area, supporting the potential for multiple near-surface mineralized layers at Pardo. Assays remain pending from surrounding holes, and additional drilling will test the grade, extent and continuity of the Matinenda Layer.

Upper Conglomerate Layer

Sampling of the Upper Conglomerate Layer is ongoing. The Company is completing assays on previously unsampled intervals from Phase 1 and Phase 2 drill holes to evaluate the Upper Conglomerate as an additional shallow conglomerate target.

Results from this work will be released once the assays are received. The objective is to determine whether the Upper Conglomerate adds another near-surface, flat-lying mineralized layer that can be incorporated into the planned maiden resource estimate.

NEXT STEPS

• Advance production permitting for the near-surface part of the Main Conglomerate layer, targeted for mid-2027.

Wesley Whymark, CEO & Director, comments: "This is an exciting stage for Inventus. With bulk sample processing underway and Phase 2 drilling restarted, we are advancing the key work programs needed to support a maiden resource estimate while also evaluating a practical pathway toward potential near-term cash flow. The latest drill results continue to highlight what makes Pardo compelling: shallow, flat-lying gold mineralization with simple geometry. The Main Layer's near-surface position, continuity and ability to be defined with close-spaced grade-control drilling support our view that it provides a strong foundation for future development planning, while results from the Matinenda Layer add confidence in the broader potential of multiple stacked mineralized conglomerate layers."
