At the Wedge Project, (3) Bore Hole Electromagnetic (BHEM) surveys were completed by EarthEx Geophysical Solutions Inc. ("EarthEx" or "EEX"), one to the south (WD-24-01) collared in the footwall sediments targeting the deposit at depth and (2) holes drilled from the north (WD-24-05, WD-24-06) into the "New" unmined, eastern extension area.

Preliminary results from WD-24-01 BHEM survey indicate a moderate to strong anomaly with initial modeling reflecting the mineralized intersections that included 11.10 meters assaying 1.37% Cu, 0.21% Pb, 0.29% Zn, 19.02 g/t Ag and 0.36 g/t Au (refer news release April 3, 2024). EarthEx has been provided with the historic drilling and further modeling is being conducted to determine the anomaly size and scale.

Drill holes WD-24-05 and WD-24-06 were collared in the north and drilled to the southeast targeting the unmined eastern portion of the deposit. Results from WD-24-05 have near hole responses in areas of elevated assay values as expected in addition to a larger size, moderate to strong conductor. WD-24-05 uncovered VMS Mineralization in (4) Zones between 18.00 and 119.00 meters. Assay values from WD-24-05 included an 18-meter intersection assaying 0.72% Cu, 0.33% Zn, 2.2 g/t Ag and 0.03 g/t Au (refer news release June 24, 2024). A moderate to strong conductor is also seen in WD-24-06 and due to the proximity to WD-24-05, the response likely reflects the same source, the drill hole having a 10-meter intersection assaying 1.53% Cu, 0.81% Zn, 7.0 g/t Ag and 0.08 g/t Au (refer news release June 24, 2024). Additional modeling is being conducted to better constrain the anomaly and improve accuracy for drilling.

The preliminary results from the California Lake CL-23-10-01 BHEM survey, indicated a weak to moderate conductor at depth.

While we await the final results of the BHEM surveys, interpretation and 3D modeling, EarthEx has initiated high priority ground-based Time Domain Electromagnetic (TDEM) surveying over previously identified priority conductors at the Wedge including targets 3, 4, 6 and 7, to further define the respective anomalies (Figure 2). Located in the western Wedge trend, the TDEM survey over the clustered anomalies provides the opportunity to validate the trend with high priority drill targets. Several lines are also planned over Target 6 which is along the southern extension of the California Lake East VMS trend that was successfully drilled in 2022.

At California Lake, Target Areas 10 and 11 were previously defined by EarthEX, the reprocessed MegaTEM data identifying numerous strong, late time conductive trends crudely forming a fold nose as seen in red in Figure 1 and highlighted by the red polylines that define the conductive axis. With a moderate conductor identified in CL-23-10-01 at a depth of 230.00 meters and adjacent, unresolved conductors, a ground-based Time Domain Electromagnetic (TDEM) survey will be undertaken, the grid location shown in Figure 3, the southern corner of the grid proximal to the South Branch Forty Mile Brook Cu, Zn mineral occurrence identified by the yellow circle.

In conjunction with the TDEM program, EarthEx is also conducting a large, 1,400-line kilometer, close spaced UAV (Drone) magnetic survey over the California Lake project areas including target areas 1 through 10. The drone survey is underway in addition to linecutting to facilitate the ground based TDEM surveys (Figure 4).

Gary Lohman, P.Geo., VP Exploration, stated, "The entire Team at Nine Mile Metals, EarthEX, Line Cutters and Drillers, have been working for the past 2 months at the Wedge and California Lake Projects, propelling this important Exploration Program forward at an expedited rate. With all 3 surveys complete, the team will have a complete picture of the geophysical characteristics of the targets allowing us to move swiftly into our Phase 2 Drill Program. We look forward to our next update with all our results, findings, interpretation and 3D Modeling with distinct High Priority Drill targets."

NEXT STEPS:

• Maxwell plate modeling of the TDEM survey data.
• 3 D modeling of the magnetics to refine lithological boundaries and identify controlling structures.
• Data integration of all 3 geophysical surveys with the historic and 2024 drill data.
• Identification and Prioritization of drill targets.
• Diamond drilling.
