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.

completed during 2023 and planned for 2023) and the interpreted >1% mineralization envelope
defined in drilling.
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.

geology. Stated drill hole intersections are all core length, and true width is expected to be 60%
to 95% of stated length.

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.

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.

DRILL HOLE SR23-05 and SR23-06 DETAILS
SR23-05 and SR23-06 were drilled along section 464900E. The holes were drilled to a downhole
depth of 131.1m and 166.1m respectively and were designed to test the continuity of the
mineralization within the central-west 4100N Zone, and either side of a single historical drill
hole (ST00-60).
Both drill holes intersected multiple wide zones of vein and fracture-style copper sulfide
mineralization hosted within fractured dolomite. The higher-grade zones of mineralization (>2%
Cu) are contained within much wider intervals of consistent lower-grade copper mineralization
(>0.5% Cu).
