Aston Bay Holdings outlines 17 showings at Epworth

Executive Summary

• Aston Bay Holdings identified 17 new base and precious metal showings during its 2025 summer field program at the Epworth project in Nunavut, Canada.
• High-grade grab samples returned significant intercepts, including up to 29.2% Cu with 217 g/t Ag, 5.42% Cu with 1.89 g/t Au, and up to 10.1% Zn with 17.8% Pb and 379 ppm Co.
• Mineralization is spatially correlated with MobileMT geophysical conductors, de-risking targets for a planned 2026 drill program focused on stratigraphic and vein-hosted copper-silver-cobalt systems.

Key Details

• New Showings: 17 new base and precious metal showings discovered in the southern portion of the property, an area with limited prior exploration.
• High-Grade Vein Mineralization: Greenback showing returned up to 29.2% Cu with 217 g/t Ag in chalcocite veinlets within Lower Rocknest dolomite.
• Disseminated Mineralization: Expert showing yielded up to 5.42% Cu with 1.89 g/t Au; Clastic showing returned up to 3.73% Cu with 2.08 g/t Au in Upper Odjick clastic rocks.
• Zinc-Lead-Cobalt Results: 3BD showing returned up to 10.1% Zn; Bob and Val showings returned up to 17.8% Pb and 13% Pb respectively, with up to 1.9% and 5.2% Zn; cobalt values up to 379 ppm recorded.
• Geophysical Correlation: Mineralization aligns with MobileMT conductors (deep/lower-frequency up to 900m below surface and near-surface/higher-frequency anomalies), supporting a sediment-hosted copper system and potential buried mineralization.
• Geological Context: Mineralization identified in rarely outcropping Recluse group rocks (proposed source of conductors), Lower Rocknest dolomites, and Upper Odjick clastic rocks. Hike showing in Recluse group returned up to 3.75% Zn and 0.18% Pb, acting as an indicator for buried mineralization.
• Field Program Details: 7 crew members from Emerald Geological Services worked for 4 weeks across two float-plane campsites in the southern half of the property.
• QA/QC Protocols: Samples analyzed at Activation Laboratories (ActLabs) using methods UT-6M, 8-4, 8-peroxide, 8-Ag, 1A2-50, 1A3-50, and 1C-Exp. CRMs included OREAS 166, 920b, 230, 24d, 135b, and 24b.
• Future Exploration: Data will be integrated into an anticipated 2026 drill program targeting large/high-grade stratigraphic Cu-Ag-Co mineralization and high-grade Ag-Cu veins.
• Property & Agreement Details: Epworth property comprises 85 claims (~102,200 hectares, ~94 km strike length). Aston Bay can earn an 80% undivided interest by spending $3 million over four years under an agreement with Emerald Geological Services.

Notable Quotes

• Thomas Ullrich, CEO: "We are extremely pleased to discover multiple base and precious metal showings during the 2025 mapping and prospecting program in the southern portion of the property, an area that had seen little previous exploration."
• Thomas Ullrich, CEO: "These strongly mineralized zones indicate an efficient mineralizing system, and their location immediately above the large geophysical conductors defined by the MobileMT survey suggests a link to potentially more mineralization hidden in the subsurface."
• Thomas Ullrich, CEO: "With the market trend toward record copper and silver prices, we are excited to integrate the new data into an anticipated 2026 drill program targeting potential large and high-grade stratigraphic (sediment-hosted-style) copper-silver-cobalt mineralization as well as high-grade silver-copper veins."
• Bruce MacLachlan, Emerald Geological Services: "Emerald Geological Services believes that the discovery of these multiple new base and precious metal showings on the Epworth project highlights the huge potential of this land package and its underexplored nature."
