TORONTO, ON / ACCESSWIRE / June 6, 2023 / Aston Bay Holdings Ltd. (TSXV:BAY)(OTCQB:ATBHF) ("Aston Bay" or the "Company") reports additional assay results confirm thick intervals of copper mineralization from its ongoing delineation drilling program at the Storm Copper Project ("Storm" or the "Project") on Somerset Island, Nunavut, Canada. This is the second drilling program for American West Metals Limited ("American West"), who are the project operator, since entering an option agreement with Aston Bay in March 2021.

Assay results have been received for an additional five drill holes from the current program at the 4100N Zone, and all have intersected thick intervals of near-surface copper sulfides with grades up to 7% Cu. The assays continue to match or exceed visual estimations as previously reported.

The near-surface setting, thick intersections, and high grades of the copper mineralization support the potential for a low-cost open pit mining operation. We continue to assess this outstanding opportunity with resource modeling, beneficiation test work and environmental studies in progress.

"Once again, the impressive results continue to come in from the ongoing exploration conducted by our partner American West Metals at Storm," stated Thomas Ullrich, CEO of Aston Bay.

"We believe these high-grade copper intercepts will support the development of a significant resource. We look forward to further results from our spring program and anticipate an exciting second program coming up this summer at Storm."

INCREASING RESOURCE CONFIDENCE AND SIZE POTENTIAL

Assay results from drill holes SR23-02, SR23-03, SR23-04, SR23-05 and SR23-06 have been received and confirm thick intervals of near-surface copper sulfides within the 4100N Zone.

The drilling results received to date demonstrate consistent copper grades and excellent lateral continuity of the high-grade mineralization. Additionally, drilling results show significant thicknesses of coherent copper mineralization (<1% Cu) are present outside of the stronger zones of mineralization.

Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Laboratory assays are required to determine the presence and grade of any contained mineralization within the reported visual intersections of copper mineralization. Portable XRF is used as an aid in the determination of mineral type and abundance during the geological logging process.

Table 1: 2023 program drill hole details and copper mineralization summary. The "Thickness of Strong Mineralization" data is based on laboratory assays (in bold) and visual estimates aided by Portable XRF analysis.

DRILL HOLE SR23-02 DETAILS

SR23-02 was drilled to a downhole depth of 140.2m and is located on the same drill section as previously reported drill hole SR23-01 (see May 23, 2023 Aston Bay press release).

The drill hole is located on drill section 465000E and was testing the continuation of the mineralization south of historical drill hole ST99-47 (Figures 3 and 4).

SR23-02 intersected a single, but wide zone of strong vein and fracture-style copper sulfide mineralization hosted within fractured dolomite.

Figure 4: Geological section view at 465000E showing the interpreted mineralization envelopes (>0.5% & >1% Cu) and recent drill hole assays and visual observations. Stated drill hole intersections are all core length, and true width is expected to be 60% to 95% of stated length.

Table 2 through 6 below summarise the significant intersections in drilling for this batch of results. Intersections are expressed as downhole widths and are interpreted to be approximately 90-100% of true width. A cut-off grade of 0.5% copper is used to define a significant intersection and is based on ore mineralogy, mineralization habit and expected beneficiation performance.

Table 2: Summary of significant drilling intersections for drill hole SR23-02 (>0.5% Cu)

DRILL HOLE SR23-03 and SR23-04 DETAILS

SR23-03 and SR23-04 were drilled on section 465050E, which lies to the east of drill holes SR23-01 and SR23-02. The holes were drilled to a downhole depth of 151m and 152.4m respectively and were designed to test the continuity of the mineralization within an area of no previous drilling.

Both drill holes intersected multiple zones of vein and fracture-style copper sulfide mineralization hosted within fractured dolomite. Drill hole SR23-03 displays distinct zoning of the copper sulfide minerals, with a dense chalcocite core, grading outwards vertically to bornite, and then to chalcopyrite on the margins of the mineralized horizon.
