TORONTO, ON / ACCESS Newswire / July 24, 2025 / Eskay Mining Corp. ("Eskay" or the "Company") (TSXV:ESK)(OTC PINK:ESKYF)(Frankfurt:KN7)(WKN:A0YDPM) is pleased to provide an update on its aggressive prospecting and sampling program at its 100% controlled and consolidated Eskay Project in the heart of the Golden Triangle, British Columbia. The Company's geological team has systematically prospected and sampled the Vermillion, TM, Red Lightning, and Big Red Zones surrounding Unuk Finger Mountain in the southern extent of the Property where high grade gold veins were discovered in 2024.

Veining in these areas has been found to be much more extensive than previously recognized. To date, 268 surface rock samples have been collected and delivered to MSA Labs. Of the 268 surface rock samples, 29 channel samples were cut across an aggregate of 25.25 metres in the Vermillion Zone across vein zones of known gold mineralization hosted in planar and sheeted quartz veining (Figure 1).

Continued prospecting and mapping in the Vermillion Zone has led to the discovery of in situ visible gold and electrum mineralization in samples A0514497 (Figure 2) and A0514398 (Figure 3), hosted in planar quartz manganese-carbonate veins with accessory pyrrhotite, chalcopyrite, bismuthanite, and wolframite. Sample A0514497 with visible gold mineralization was collected 5 metres northeast and on trend of 2024 sample C970477 which returned assay values of 205 g/t gold and 118 g/t silver (see News Release dated October 8, 2024). The second visible gold sample A0514398 was discovered approximately 220 metres south-southwest of sample A0514497 in a newly discovered sub-parallel vein zone. Assays for these samples are pending.

Prospecting across all zones surrounding Unuk Finger mountain has discovered new flat lying, sheeted and planar shear quartz vein zones that appear relatable to veining that returned high gold values in 2024. Veins of similar style have been observed over 600 metres vertically and 500 by 2000 metres horizontally. The style of the quartz-sulfide veins observed in these zones strongly resembles those at Goliath's Surebet gold project in the southern Golden Triangle. Like at Surebet, there is an Eocene aged intrusion at Eskay that appears to be closely associated with mineralization.

The first batch of assays from surface rocks collected in the Big Red and upper TM Zones are expected to be returned in the next 14 days.

Mapping and prospecting are ongoing in unison with drill target delineation.
