Slide 5: 2025 Results & 2026 Exploration Plan
2025 Results & 2026 Exploration Plan During 2025 Eskay expanded its Vermillion, TM, and Big Red targets, and also identified a promising new target named Sultan, all of which lie within two kilometres of the important “Kyba Line” unconformity which appears to control so many key porphyry deposits in
Slide 6: Diversity of Deposit Types
Diversity of Deposit Types The Northern-Sector Sib – Lulu VMS Target Drilling Results Projected to Surface 2026 marks a Sib-Lulu lies ~6km along strike to the southwest of the Eskay Creek Mine significant shift in focus by Eskay from predominantly VMS targets in the north to porphyry and vein gold t
Slide 7: Work in Progress
Work in Progress Two geologists are currently transferring the Company’s historical geochemical database into Rogue Geoscience’s Mantle Database System and the Company’s proprietary geological maps into QGIS. In parallel, in3D Geoscience has been contracted to transfer all the Company’s geophysics s
Slide 8: Winter 2027 Work
Winter 2027 Work Over the next winter this multi-faceted, expansive and complex data set will be re- evaluated by experienced geologists and carefully chosen cost-effective AI technologies. This work is expected to generate a number of new VMS, epithermal gold/silver and porphyry copper/gold targets
Slide 9: Vermillion
Vermillion In-situ visible gold and electrum mineralization have been identified over a 2km strike length occurring in multiple planar and sheeted quartz-carbonate veins at both the Vermillion and TM zone to the east. Veins hosting accessory pyrrhotite, chalcopyrite, bismuthinite, and rarely wolfram
Slide 10: TM
TM Gold in Rocks (g/t) Visible gold from TM sample Gold levels in rock samples collected from the TM prospect. A0519908 assaying 246 g/t Au.
Slide 11: Big Red
Big Red While assay results returned generally low Au-Ag grades, sampling revealed elevated Cu- Mo-W grades and samples plot high values on the Mineral Deposit Research Group (MDRU) porphyry index (MPIx). A higher MPIx value may indicate closer proximity to porphyry-type mineralization. Quartz-pyrit
Slide 12: Sultan
Sultan Sultan is ~5km along strike from Goldstorm’s Copernicus Prospect. Gold in Rocks (g/t) Copper in Rocks (ppm) At the end of the 2025 season one day was spent conducting reconnaissance sampling on previously unexplored areas 7km southeast of the TM Zone. Prospecting returned promising initial re
