Aston Bay and American West Metals Announce New >4-Kilometre Copper Anomaly Identified at the Storm Project, Nunavut, Canada

On November 17, 2025, Aston Bay and its partner American West Metals announced the discovery of a new, large copper-in-soil anomaly at the Storm Project in Nunavut. The anomaly, named the Chevron Prospect, is over 4 kilometres long and 0.7 kilometres wide and runs parallel to the main Storm copper trend. The CEO, Thomas Ullrich, noted that a similar soil anomaly sits above the existing near-surface copper resource at the main Storm area, suggesting the Chevron area has similar potential. The company is applying for new exploration claims to cover ground east of this new discovery.

The release also included assay results from eight Reverse Circulation (RC) drill holes from the 2025 program at various other prospects. Notable intercepts include 4.6 metres of 1.36% copper at the Squall prospect and 3.0 metres of 0.79% copper at the Gap prospect.

This news is materially positive for Aston Bay. The discovery of a large, 4-kilometre soil anomaly demonstrates the successful execution of the company's regional exploration strategy and significantly expands the project's exploration upside. While a soil anomaly is an early-stage discovery that requires follow-up geophysics and drilling to confirm mineralization, its scale and similarity to the anomaly overlying the known Storm resource make it a high-priority and compelling new target. For a company with a market capitalization under C$15 million, adding a target of this magnitude is a significant development that reinforces the "belt-scale" potential management has consistently highlighted.

Reviewing the historical news provides crucial context: - Q1 2025: The company achieved a major milestone by delivering a maiden NI 43-101 Mineral Resource Estimate (MRE) for Storm, defining 8.2Mt @ 1.47% Cu (Indicated) and 3.3Mt @ 1.30% Cu (Inferred). This de-risked the project by quantifying a substantial near-surface resource. - Q2 2025: A critical financing and development risk was addressed when JV partner American West secured a strategic alliance with Ocean Partners. This deal includes 100% offtake rights and a commitment for up to 80% of initial development capital (subject to a bankable feasibility study). This was a major vote of confidence from a sophisticated base metals group. The company also outlined its 2025 exploration plan focused on both resource expansion and regional discovery. - Q3 2025: News flow from the summer drill program began, with encouraging visual results followed by solid assays in August (e.g., 12.2m @ 1.9% Cu) and the identification of large geophysical targets from an MMT survey in September. - October 2025: The company announced drill results that intersected copper mineralization outside of the current resource pit shells (e.g., 12.1m @ 5.6% Cu), directly supporting the potential for resource growth.

The latest news builds directly on this track record of methodical de-risking and exploration success. While the October news confirmed the potential to grow the existing resource, this November news demonstrates the potential to make entirely new, large-scale discoveries elsewhere on the property. The accompanying drill results are supportive, confirming continued mineralization at other prospects, but the key takeaway is the scale of the new Chevron discovery. The news validates the exploration model and materially increases the long-term potential of the Storm Project.

Aston Bay Holdings is a junior mineral exploration company focused on projects in Nunavut, Canada. Its flagship asset is the Storm Copper Project on Somerset Island, a joint venture with American West Metals (AWN). Aston Bay holds a 20% interest, which is free-carried by AWN (the 80% owner and operator) through to a decision to mine following a bankable feasibility study. The project hosts a near-surface, high-grade sediment-hosted copper resource. The company also holds the 100%-owned Epworth Copper Project in Nunavut.
