TORONTO, Ontario 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.
Thomas Ullrich, Chief Executive Officer of Aston Bay, commented:
“Analysis of the 2024 exploration programs at Epworth is delivering exciting results pointing to the potential for large-scale copper mineralization at the property.
“The surface sampling programs have confirmed previous work where large boulders yielding up to 61.2% copper with 5,600 g/t silver were found at the surface along with several other zones of high-grade metal mineralization. With significant lead, zinc, gold and anomalous cobalt in several newly discovered areas on this large property, we have only scratched the surface.
“These are excellent results, but with mineralization typically confined to structurally controlled fracture filling (veins), building significant tonnage of mineralized material can be challenging. The widespread nature of the metal mineralization, however, points to the potential for large-scale stratigraphically-controlled mineralization at depth – this is the sediment-hosted copper deposit model used to find the large copper deposits of Central Africa and successfully used at our other project, Storm Copper.
“Of the key components required to form an extensive sediment-hosted copper system, the discovery of these conductors provides the final piece of the puzzle at Epworth: these conductors may represent the reductant, in the form of pyrite or graphite in a permeable horizon, that forces the precipitation of metals over large areas within this stratigraphic unit and bounding faults. The first interaction of metal-bearing fluids with a reductant is the site of metal sulfide deposition in this model, providing a large target of potential metal accumulation. As well, the conductors may represent some metal sulfide mineralization themselves.
“These are compelling targets tens of kilometres in scale, mostly within 300m from the surface. We continue to work with the data to refine optimal drill targets for a potential drill program later this season.”
MobileMT Survey Summary
In late summer 2024, a property-wide airborne MobileMT (Mobile MagnetoTelluric) geophysical survey was completed at the Epworth Project in Nunavut. The survey, conducted by Expert Geophysical Systems, covered 8,105 line-kilometres across the entire extant claim block, with 100-metre line spacing in the northern half and 200-metre spacing in the southern half to ensure high-resolution data over priority areas.
