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

Thick interval of visual copper sulfide identified in historical drilling supports the potential for discovery and highlights significant untapped regional potential Highlights: More than 58m of visual copper sulfides identified in historical drill hole: Drill hole AB18-04 was drilled in 2018, approximately 5km west of the Storm Mineral Resource Estimate ("MRE") in an area now named the Midway Prospect. The drill hole was logged as intersecting more than 58m in total of intermittent visual copper sulfides, but has yet to be sampled and assayed.» Mehr auf accessnewswire.com
