Inventus Expands Pardo With Strong Drill Results and Advances Multiple Gold Layers Toward a Maiden Resource

TORONTO, ON / ACCESS Newswire / April 1, 2026 / Inventus Mining Corp. (TSXV:IVS) ("Inventus" or the "Company")is pleased to report new assay results from its ongoing Phase 2 drill program at its 100%-owned Pardo "River of Gold" Project, located 65 km northeast of Sudbury, Ontario. These results continue to expand the footprint of near-surface gold mineralization and support the development of a growing multi-layer gold system with the potential to significantly increase total tonnes and ounces ahead of the Company's maiden resource estimate.

HIGHLIGHTS

• Results continue to support the expansion of a stacked gold system with potential to significantly increase total tonnes and ounces ahead of a maiden resource estimate.

RECENT DRILL RESULTS EXPANDING A GROWING GOLD SYSTEM

The ongoing Phase 2 drill program has demonstrated continuity of gold mineralization to the Southeast and Northwest. Drill result highlights and drill hole details are presented in Figure 1 and Table 3 & 4. The footprint of drilling has now increased by 150% from 0.2 km² to 0.5 km², representing approximately 20% of the 2.5 km² exploration target area that remains open for expansion (Figure 2).

Importantly, drilling is not only expanding the Main Conglomerate Layer but is also improving the Company's understanding of additional mineralized layers that were historically underexplored.

THREE STACKED GOLD LAYERS - A MAJOR INCREASE IN PROJECT SCALE

With strong gold prices and the potential for ore sorting and heap leach processing options, the Company is expanding its focus beyond the single high-grade main layer and advancing Pardo as a larger, multi-layer gold system.

Drilling to date has primarily targeted the Main Conglomerate Layer, however, a review of previous drilling has highlighted two additional gold-bearing layers, the Upper and Matinenda Conglomerates, that remain largely unsampled but have clear potential to add significant tonnes and ounces (Figure 3).

Together, these three flat-lying, laterally continuous layers form a stacked sequence of gold mineralization that can be tested within a single drill hole, significantly improving exploration efficiency (Figure 4). The Company is now systematically assaying previously unsampled intervals from previous drilling to advance all three layers toward a maiden resource estimate, with the potential to materially increase the total tonnes and ounces within a large-scale surface strip-mining operation. A detailed description of each layer is provided below:

1. Main Conglomerate Layer (MiBC)

The Main Conglomerate layer remains the primary focus of ongoing Phase 2 drilling and forms the foundation of the Company's exploration target of 12.5 million tonnes at 3.5 g/t gold (See Technical Report April 10, 2018), and remaining open for expansion. This unit averages approximately 2 metres in thickness and hosts the highest-grade mineralization identified to date. Where the layer occurs within 15 metres of surface, it has been the focus of the Company's bulk sampling program, which has demonstrated strong and repeatable economics supporting its development potential. The Company is advancing the near-surface area of this unit toward a production permit and near-term development pathway, including ore sorting to upgrade material for direct shipping and processing. This strategy would minimize capital requirements and generating early cash flow to support the development of a larger-scale operation.

2. Upper Conglomerate Layer (MiPC)

The Upper Conglomerate Layer is a laterally extensive unit that represents a compelling large-tonnage, lower-grade opportunity. It sits above the Main Conglomerate layer and is typically present where the sedimentary sequence exceeds 20 metres in thickness (Figure 3 & 4). Highlights of previous drill results for this unit are shown in Table 1, and its currently known extent of approximately 3.68 km², which remains open for expansion. The unit can occur as multiple mineralized zones or as a thicker >10 metre continuous interval with grades between 0.2 and 0.5 g/t gold. While historically not a primary focus, the current gold price environment and potential ore sorting and heap leach processing have increased its importance. This unit remains largely unsampled across the property; however, where it is present in completed Phase 1 and Phase 2 drill holes, it will be systematically sampled as part of the Company's ongoing work program to better define its size, grade, and contribution to total tonnes and ounces in the upcoming resource estimate.

3. Matinenda Conglomerate Layer (MaC)

The Matinenda Conglomerate Layer occurs at the base of the sedimentary sequence on the west side of the property and in places occurs at surface where erosion has exposed it (Figure 3 & 4). It is characterized by higher sulphide (pyrite) content associated with gold and, while underexplored, has returned encouraging historical drill results (Table 2). The unit's currently known extent is approximately 2.13 km² and remains open for expansion. Given its sulphide-rich nature, the Company is evaluating its metallurgy and ore sorting potential, with the objective of producing a higher-grade sulphide concentrate. This layer represents a compelling opportunity to generate higher-grade material and could play an important role in enhancing project economics as part of a multi-layer development strategy.

INTEGRATED DEVELOPMENT STRATEGY

The presence of three stacked gold-bearing layers at Pardo allows the Company to evaluate a scalable development approach that maximizes total tonnes, ounces and value.

The Company is currently assessing:

• Bulk surface mining potential across all three layers with low strip ratios

• Grade-specific processing options, including ore sorting and direct shipping of higher-grade material (Main and Matinenda Layer) and heap leaching of lower grade material (Upper Layer and lower grade sorted products).

• Selective mining approaches to prioritize higher-grade zones where appropriate

• Optimization of the overall development plan to reduce capital intensity and improve project economics

This work is aimed at defining the most efficient development pathway while supporting potential near-term cash flow and long-term scalability of the Project.

BULK SAMPLE PROGRAM UPDATE

The Company is currently advancing two separate bulk samples at Pardo. The Trench 1 bulk sample (10,000 tonnes), of which 2,512 tonnes have already been processed (see news release March 18, 2026), with the remaining 7,500 tonnes currently at the mill and expected to be processed in the second half of April.

The Trench 1 North bulk sample (10,000 tonnes), with extraction now complete. Approximately 2,500 tonnes have been transported to the mill for processing, with the remaining 7,500 tonnes expected to be hauled in June once spring half-load road restrictions have been lifted.

The Company has also completed an additional 28-grade control holes with assays pending. This recent grade control drilling will support the final extraction of the remaining 20,000 tonnes of permitted bulk sample material.

NEXT STEPS

• Continue drilling to expand the mineralized footprint, including targeted testing of the Upper and Matinenda Conglomerate layers

• Complete assaying of previously unsampled intervals in Phase 1 and Phase 2 drilling, particularly within the Upper Conglomerate layer

• Advance the maiden resource estimate incorporating all three mineralized layers

• Complete the remaining bulk sample program, including processing existing material and extracting the final 20,000 tonnes to support ongoing development and evaluation

• Ongoing processing test work of all three layers

• Advance the Company's planned production permit for near-surface portions of the Main Conglomerate layer in mid-2027

• Continue evaluation of mining and development scenarios to optimize project scale, economics, and potential production pathways

Wesley Whymark, CEO, comments: "These latest drill results continue to demonstrate that Pardo is evolving into a significantly larger and more robust gold system. We are no longer looking at a single layer of gold mineralization, but a stacked system of multiple gold-bearing layers, which represents a major step forward in increasing the overall scale of the project. As we continue to advance and incorporate these additional layers, we see a clear path to growing both the total tonnes and ounces ahead of our maiden resource."
