Regional geochemical soil sampling highlights a large and untested copper anomaly parallel to the Storm trend
Highlights:
- New, greater than four-kilometre (“km”) long copper anomaly discovered: The regional soil geochemistry program has defined a very strong, high-priority 4.1km by 0.7km copper anomaly, now named the Chevron Prospect.
- High-priority target: The geological features of the Chevron Prospect are similar to those that host the known copper deposits in the Storm area – including a similar geochemical signature and structural trend – making Chevron a compelling target for a major new copper discovery.
- Squall high-grade copper zone expanded: Assays confirm further high-grade copper sulphides at the Squall Prospect, which show a similar setting and style of mineralization to the Corona Copper Deposit, 1.3Km to the east, including drill hole SR25-012, which intersected:
- 4.5m @ 1.4% copper (“Cu”), 2.6 grams per tonne (g/t) silver (“Ag”) from 158.5 metres (“m”), including:
- 1.5m @ 3.6% Cu, 5.0 g/t Ag from 158.5m
- Copper sulphides intersected in the Tornado area, confirming prospectivity: Widespread copper has been intersected in drilling within the prospective Allen Bay Formation and extensive fault network in the Tornado area, confirming the prospectivity of this high-priority exploration area.
TORONTO, Ontario, November 17, 2025 – Aston Bay Holdings Ltd. (TSXV: BAY) (OTCQB: ATBHF) ("Aston Bay" or the "Company") is pleased to provide an update on exploration activities at the Storm Copper Project ("Storm" or the "Project") on Somerset Island, Nunavut. American West Metals Limited ("American West"), the Project operator, is conducting the exploration program. Aston Bay and American West have formed a 20/80 unincorporated joint venture with respect to the Storm Project property, with Aston Bay maintaining a free carried interest until a decision to mine is made upon completion of a bankable feasibility study.
Thomas Ullrich, Chief Executive Officer of Aston Bay, commented:
"We are very excited by this discovery of a new Storm-sized copper anomaly at our Project on Somerset Island. At the main Storm area, a similar copper-in-soil anomaly sits above a significant near-surface copper resource, as well as above several other deeper copper discoveries. The newly identified Chevron area shows similar potential. This four-kilometre trend has seen no significant surface sampling to date, and no geophysics or drilling has ever been conducted. The follow-up exploration will add significant discovery potential to next season’s program, in addition to the compelling targets already defined by this year’s helicopter-borne Mobile Magnetotelluric geophysical survey.
“The positive results from this season’s reverse circulation (“RC”) drilling program also continue to demonstrate the prospectivity and expansion potential at the main Storm area.
“These discoveries speak to the still-untapped exploration potential of the Project. It is thrilling to advance the development activities for the Storm resource while adding potential value through discovery each season.”
