Edjudina Gold Project

The Edjudina Project is located approximately 150km northeast of Kalgoorlie in Western Australia. It covers a section of the established mineralised trend along the Keith-Kilkenny Tectonic Zone which hosts multiple significant gold discoveries (see Figure 1). No large-scale mining has occurred within the tenement area, however, historical near surface workings can be observed throughout the region, particularly within and along strike of the previous mines in the Yilgangi Mining Field. The Company’s tenements (both granted and under application) are proximal to Northern Star’s operations at both the Porphyry and Carosue Dam operations (see Figure 1).

The Victoria Bore Copper Project is centred on the historic Victoria Copper Mine which produced high grade copper averaging circa 32.7% Cu for 62.5t of copper from near surface in the 1950’s. The Victoria Bore Project is located approximately 120km south of the town of Onslow and 130km southeast of Exmouth in Western Australia. The tenements lie adjacent to the Northwest Coastal Highway and are readily accessible (see Figure 2).

Recent Activities

During the quarter, the M3M team contracted Resource Potentials to undertake a geophysical data compilation and targeting exercise across the Project, given the large amount of open file, detailed geophysical data available. Results are expected to be released in the following quarter.

Planning is underway for an aircore program at the El Capitan prospect, following a review undertaken of drilling to date by M3M and previous explorers. The review indicated a number of potential areas require follow up drilling.

The Company continues to progress a heritage agreement at the Edjudina Project.

Corporate

During the quarter, the Company announced that it has received firm commitments to raise $2,250,000 (before costs) through a placement of 125,000,000 shares (Placement Shares) at an issue price of $0.018 each (Placement).

The funds raised from the Placement will be used towards exploration activities at Victoria Bore and Edjudina, which will include geophysics, regional aircore drilling and follow up aircore drilling at El Capitan. In accordance with the strategic review, funds raised from the Placement will also be used towards assessing opportunities to expand or diversify the Company’s exploration portfolio through the addition of high-quality assets with strong strategic fit, as well as towards general working capital.

The Placement is being completed in two tranches, with 12,500,000 Placement Shares issued pursuant to the Company’s placement capacity under Listing Rule 7.1 and the Company sought shareholder approval for the issue of the remaining 112,500,000 Placement Shares at a General Meeting that was held on 27 October 2025.

During the quarter, the Company has assessed multiple resource project opportunities with preliminary commercial discussions currently underway.

Subsequent to the end of the quarter, all resolutions were passed at the General Meeting with strong shareholder support received.
