Aston Bay and American West Metals Announce New Copper Targets at the Storm Copper Project, Canada - Seite 2

"It is very encouraging to see geophysics identify new targets at Storm," stated Thomas Ullrich, CEO of Aston Bay. "Moving Loop EM anomalies have demonstrated a very strong correlation with high-grade copper mineralization, so these are high-priority drill targets. This initial phase of geophysics is designed to be effective in the shallow subsurface, less than 200 metres depth, well within reach of the RC drill rigs on site. The ongoing drilling will aim to test these targets in the coming weeks and over the summer program.

"The upcoming deep-penetrating, wider-spaced MLEM survey is designed to explore the Storm central graben area below the known mineralization with a targeted search space of 200-500m depth. This opens a whole new space for potential discovery. In the 2024 season we intersected copper mineralization at these depths with the same mineralogy as seen at the surface. We anticipate these deeper-looking surveys will enhance our drill targeting for potentially thicker and more laterally extensive zones of mineralization in this very prospective but underexplored zone."

PHASE 1 MOVING LOOP ELECTROMAGNETICS (MLEM)

The high-powered MLEM survey is advancing rapidly and is initially being used to highlight the priority areas within the Storm area for expansion of the near-surface zones of higher-grade copper mineralization and to identify new targets for drilling (Figure 2).

The copper mineralization at Storm is dominantly chalcocite (a copper sulfide mineral with 79.8% Cu content), occurring as massive sulfides in breccias and veinlets. Minor chalcopyrite (copper sulfide with 34.5% Cu content) is present on the margins of the mineralized profiles. The contrast in conductivity between chalcocite and the highly resistive dolomite host rocks makes EM an effective targeting tool in this area.

The initial MLEM surveys at Storm have used 200m N-S line spacings, 100m sensor stations, and 200m x 200m loops. This configuration provides rapid coverage and is effective in defining the known near-surface high-grade copper mineralization at Storm.

Hotter colours (red/green) indicate higher conductivity. Gaps in this survey were completed in 2023 and will be integrated into the final modeling and interpretation.
