Update on Winter Drill Program

The Company had previously announced its intent to complete a 3,000 metre (“m”) diamond drillhole (“DDH”) program with the intent of extending the known mineralization at depth and to the west. With the closing of the oversubscribed equity offering announced on October 30, 2025, we have modified our program increasing it to eight planned DDH’s for a total of approximately 3,900 metres. Figure 1 shows the plan view of the winter drill program as well as the drill traces from the 2018, 2021 and 2024 program. The gold zone intercepts are highlighted on these drill traces as well as the surface view of the North, Central and South Gold Zones that have been modeled. With the updated modeling completed earlier this year, we have been able to incorporate a prior 3D Alpha IP and Mag survey that demonstrated a high correlation between mineralization and areas of high chargeability and low resistivity. The surface view of the modeled gold zones and drill traces have been overlayed onto the resistivity survey at a depth of 225 m.

The Company commenced the winter drill program in early November and has completed approximately 1,312 m of drilling to date. We anticipate closing camp at the end of the second week of December providing a break in the activities, allowing the field crews a chance to recuperate over the holidays and the Company will recommence field activities early in the new year.

Extending at Depth

The first five DDH’s of the winter program are targeted at exploring the extension of the known mineralization at depth. Figure 2 shows a western view of the drill program with the planned drillholes shown in red. Three horizontal section planes of the IP survey are shown at depths of 125 m, 175 m and 225 m demonstrating the low resistivity anomaly that is highly correlated with mineralization. Sections from the survey show the low resistivity anomaly down through the entire IP survey with a depth of 500 m. The interpretations of the South and North Gold Zones can be seen in the graphic

LM25-01 is a re-entry and extension of DDH LM24-05 that was drilled from the north to the south and appeared to stop at the edge of the low resistivity anomaly and the Company believes it was a cost effective way to test the depth extensions in the southern edge of the anomaly. The extension to this hole was 240 m to a total drilled depth of 600 m and samples have been delivered to the lab for assaying and results will be provided when received in the coming weeks.

LM25-02 and LM25-04 will both be drilled on a south to north orientation and are intended to test at depth the extensions of the mineralization. Figure 3 is the section for the approximate location for these two drillholes. LM 25-02 was completed to a drilling depth of 530 m and the “leopard rock” package which forms the footwall on the North Zone was within approximately five meters of where we had modeled this intercept. Samples for assaying have been delivered to the lab and results for LM25-02 are pending. LM25-04 will be collard to the south of LM25-02 by approximately 100 m with a planned drilling depth of 675 m. As the zones are interpreted, this hole would intercept mineralization approximately 300 m below the mineralized intercepts shown on Figure 3. It is anticipated that LM25-04 will be completed following the holiday break.

LM25-03 has a planned drilling depth of 600 m drilling a south to north orientation. This hole is targeting the area where DDH’s 24-06^[1] and 24-07^[2] demonstrated that the North and Central zones were converging creating a wider area of mineralization. This hole is 90% complete and we anticipate having the samples delivered to the lab for assaying before the holiday break.

LM25-05 has a planned drilling depth of 500 m and will have a southwest to northeast orientation with a goal of avoiding the mildly easterly dipping diabase dyke. This hole is targeted because of the nearly 50 m wide occurrence of the South Zone at surface which also correlates strongly with the wide intercepts of DDH’s LM24-09^[3] and LM24-10^[4] which showed wide intercepts in the same zone just west of the post mineralization diabase dike. LM 25-05 will not only test the depth extension of the South Zone but will also test the extension of the North Zone as is demonstrated in Figure 4. This graphic is a good example of the intent of this drill program testing the deeper extensions of mineralization. It shows the horizon of the resistivity at 225 m and the modeled South and North Gold Zones and the approximate areas we would expect to intercept those zones at depth.

Extending Laterally to the West

The final three holes of the winter drill program are targeted at extending the known mineralization laterally to the west. If LM25-08 is successful, it will demonstrate the continuation of the mineralization, 600 m to the west of the 1.6km conceptual pit modeled in our recently published NI 43-101. Figure 5 shows an east facing 3D view of the drill program with the three resistivity horizons. The planned DDH’s for 2025 are shown in red and the drill traces from 2024 are shown in yellow. The drillholes planned for the western portion of the program are testing three areas identified in the 3D Alpha IP and Mag survey.

LM25-06 and LM25-07 are being drilled on the section seen in Figure 6 showing the two targets identified in the survey (DDH-5 and DDH-6). These targets are 290 m West of the final two DDH’s drilled in 2024. LM 25-06 has a planned drilling depth of 350 m and will target the northern edge of the low resistivity anomaly. LM25-07 has a planned depth of 500 m and will test the large heart of the anomaly below the identified target DDH-5.

LM25-08 will be collared 300 m further west with a planned depth of 500m with a south to north orientation. This drillhole will also be testing the heart of the low resistivity anomaly, similar to LM25-07, and further extending the mineralization laterally to the west.
