Initial Mag & TDEM airborne geophysical survey completed in 2023

several high priority targets generated from initial geophysical survey - Ranger, Rush, Rogue

Inaugural Drill Program completed April 2024

Rottenstone SW land package increased to a total of 32,715 Ha

Ranger-001 discovery hole with multiple gold zones, including 73.55 g/t Au and 19.50 g/t Ag from 227-234.5m

Gold mineralization intersected at Rogue target located 3km west, across regional strike from Ranger

New mineralized target 'Rush' discovered during Fall 2024 Field program from a mineralized outcrop at surface

• Surface rock samples returned values of up to 1.61% Cu, 0.79 g/t Au,113 g/t Ag, 1.23% Pb, and 0.64% Zn

Mag & TDEM airborne geophysical survey flown over the remaining parts of the property completed in 2025

A follow up Drill program consisting of 20 drill holes was completed in June 2025.

  Assays confirmed VMS style mineralization at Rush

New mineralized targets 'Redridge' & 'Runway discovered during Fall 2025 Field program

FLTEM ground geophysics completed over Rush to cover the 1200m long main anomaly in Fall 2025

Borehole EM completed on Rush-001, 003, 006, 007, 008, 009, and 010 & Rogue-001 & -002 in Fall 2025

Full soil sample grid completed over the entire Rush anomaly at 50m spacing returning a prominent Cu-Ag-Zn soil anomaly at Rush with additional Satellite target mineralization

Fully permitted for additional 150 drill holes & a remote camp

Drill program mobilization began on February 23, 2026
