Camp opening and logistics have commenced with geophysics and drilling to follow in the coming weeks Highlights: The 2025 drill program is set to begin. A pipeline of large-scale exploration targets prioritized for drilling includes: Cirrus Deeps - high-priority EM target below the Cirrus Deposit with a stratigraphic setting similar to Cyclone will be the first target to be tested with diamond drilling Cyclone Deeps - potential continuation of the large Cyclone Deposit at depth with reconnaissance drill intercepts such as 10 metres ("m") @ 1.2% copper ("Cu") from 311m (including 0.5m @ 3.7% Cu from 315.5m), ready for follow-up with diamond drilling Resource Expansion - several discoveries near the footprint of the Mineral Resource Estimate ("MRE") will be followed up, including the Gap Prospect, which contains a strong EM anomaly confirmed with drilling that returned 20m @ 2.3% Cu from 28m, and the Squall and Hailstorm Prospects Tornado/Blizzard - located 5km east of the Storm copper deposits, the area hosts a 3.2km x 1.5km geochemical copper anomaly and two large electromagnetic ("EM") plates yet to be drilled Midway - discovered by a single historical drill hole that intersected a total of 58m of visual copper sulfide, located approximately 5km to the west of the Storm MRE area, to be drilled Geophysics to generate new targets.» Mehr auf accessnewswire.com

All components in place for potential Central African-style copper mineralization Highlights Several large, near-surface conductors representing potentially reductive permeable stratigraphy favourable to host sediment-hosted copper mineralization delineated by airborne MobileMT geophysical survey New sampling verifies historical occurrences, including Payback Showing (up to 61.2% copper ("Cu") with 5,600 grams per tonne ("g/t") silver ("Ag")) and CBC Showing (up to 9.9% Cu, 1.9% lead ("Pb"), 3.5 g/t gold ("Au") and 431 g/t Ag) Multiple new copper, zinc and lead occurrences were discovered across the property in 2024 sampling, along with locally anomalous gold, silver and cobalt Additional mineral claims staked on prospective ground expanding claim block by 11,608 hectares ("ha") to a total of 102,108 ha (1,002 square kilometres ("km2)) TORONTO, ON / ACCESS Newswire / June 5, 2025 / Aston Bay Holdings Ltd. (TSXV:BAY)(OTCQB:ATBHF) ("Aston Bay" or the "Company") is pleased to report on sampling, mapping and geophysical programs at the Epworth Project ("Epworth" or the "Project") in Nunavut.» Mehr auf accessnewswire.com

Drilling of large-scale regional copper prospects and resource expansion targets Highlights: High-grade copper discoveries ready for resource definition drilling. Potential to rapidly increase the Initial Mineral Resource Estimate ("MRE" - see March 3, 2025, Aston Bay news release) through resource definition drilling of recent discoveries, including: Cyclone Deeps - potential continuation of the large Cyclone Deposit at depth with drill intercepts such as 10 metres ("m") @ 1.2% copper ("Cu") from 311m (including 0.5m @ 3.7% Cu from 315.5m) Cirrus Deeps - high-priority electromagnetic ("EM") target with stratigraphic setting similar to Cyclone Deeps The Gap - a strong EM anomaly confirmed as a priority copper target with drilling that returned 20m @ 2.3% Cu from 28m (including 8m @ 5.3% Cu from 39.6m) Advancing regional exploration opportunities.» Mehr auf accessnewswire.com
