TORONTO, ON, August 23, 2022 – Aston Bay Holdings Ltd. (TSXV: BAY) (OTCQB: ATBHF) ("Aston Bay" or the "Company”) is pleased to announce visual results confirming the discovery of a new zone of stratiform sulfide copper mineralization at the Company’s high-grade Storm Copper Project (“Storm” or the “Project”) on Somerset Island, Nunavut. This is the maiden 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.

Highlights

• Exploration drill hole ST22-10 has intersected over 68 metres (m) of stratiform copper sulfide mineralization from 277m downhole
• The discovery is associated with a 800m x 300m electromagnetic (EM) plate, with six other similar large EM plates yet to be tested
• This new style of mineralization at Storm is evidence of a major copper system at depth with significant copper endowment upside

“On top of outstanding copper intersections already encountered in drilling at the 2750N Zone earlier this season, we are extremely excited to intersect a new large zone of stratiform copper sulfide mineralization as predicted by our geologic model,” stated Thomas Ullrich, CEO of Aston Bay.

“Drilling at this new zone targeted one of seven large new EM anomalies that were delineated in last year’s geophysical program. These anomalies are spatially associated with known high-grade copper mineralization at the surface, as well as with faults that likely served as the plumbing system for the mineralizing fluids. The discovery of copper mineralization at depth supports our model for a major copper system below the high-grade near-surface mineralization. Six other large anomalies in the Storm area remain untested. We view this to be a significant copper discovery.”

Exploration Drilling Defines Major New Discovery
Drill hole ST22-10 has intersected a thick sequence of copper sulfide mineralization associated with a large, previously untested EM anomaly that was defined in the fixed loop EM (FLEM) survey completed over the Storm Copper Project area in 2021 (see news release dated December 14, 2021).

Approximately 68.8m of chalcopyrite dominant mineralization was intersected from 277m downhole in drill hole ST22-10 (approx. 230m vertical depth). The mineralization is interpreted to be stratiform and is hosted within a vuggy, bituminous and fossiliferous carbonate unit. This geological setting is consistent with the typical mineralization model for sedimentary copper systems where this style of permeable host rocks form chemical traps for the deposition of copper rich fluids (Figure 2).

This newly discovered mineralization and setting at Storm shares features very similar to many large volume, sedimentary hosted copper systems. Importantly, ST22-10 is the first hole to intersect one of the deeper EM anomalies modelled from the 2021 FLEM survey with six other similar EM plates yet to be tested, indicating the potential for a large-scale mineral system.

Background
Historical EM surveys have successfully identified several strong conductive anomalies that are associated with known copper mineralization at Storm. The high-powered 2021 survey completed by American West was designed to better define these historical anomalies, highlight potential extensions to the known copper mineralization and to also identify potential new targets.

The 2021 survey identified two distinct types of EM anomalies, which included strong, near-surface and sub-vertical conductors, as well as a series of large, deeper and generally flat-lying conductors (Figure 3).

The geometry and mostly gentle dips of the deep EM conductors suggested that they may be related to stratiform type targets, and therefore may be indicative of traditional sedimentary type copper mineralization.

Importantly, the new EM anomalies are located proximal to the known bounding faults of the Storm graben, which are interpreted controls on the copper mineralization at Storm.

Conductor Loop7_2 (see Figure 4) is a large conductive feature (modelled as 800 x 300m, depth ~250m, conductivity thickness 10). This target was prioritized for drilling as its eastern extent  appeared to project upwards towards the 4100N Zone, where previous high-grade intersections include 15m* @ 3.88% copper (Cu) from 72.4m (drill hole ST99-47), and therefore presented as a compelling target.

Significantly, six new EM anomalies remain to be drill tested – these include a large conductive anomaly (1,700 x 1,000m) below the highly mineralized 2750N and 2200N Zones, and another large anomaly to the east of the 4100N Zone (690 x 695m) (Figures 3, 4 and 5) where historical drilling has also intersected high-grade copper sulfides. All anomalies are located within 500m of the surface.

The deeper flat lying conductors appear as red rectangles. Stated drillhole intersections are all core length, and true width is expected to be 60% to 95% of core length.

Drill Hole ST22-10 Details
ST22-10 was drilled to a downhole depth of 382.6m and intersected two main zones of visual copper mineralization.  The drill hole was terminated prematurely due to a mechanical failure, with the deeper zone still open at depth.

The first zone encountered in ST22-10 is located near surface and consists of 34m* of weak vein style, fracture hosted and blebby chalcocite over a number of intervals from 17m downhole. This mineralization is typical of the near-surface mineralization at Storm.

The deeper zone of mineralization is over 68m* thick and is still open at depth. The mineralization consists of vein, breccia and replacement style chalcopyrite that is interpreted to be stratiform and distinctly different to the copper mineralization historically seen at Storm.

The copper sulfides are hosted within a sequence of fossiliferous/stromatolitic carbonates with zones of vugs that contain hydrocarbons (bitumen), calcite and pyrite. Abundant chalcopyrite veins are present within the upper portion of the zone associated with localized breccias (Figure 1).  Minor sphalerite (zinc sulfide) is also present within the vugs in the lower part of the sequence.

These host rocks and mineralization styles are typical of sedimentary hosted copper systems.

Additional high resolution EM work will be completed to further define these more conductive areas of the system for follow-up drilling.

Conductor Loop9_4 is located at depth to the east of the 4100N Zone and remains untested. Stated drillhole intersections are all core length, and true width is expected to be 60% to 95% of core length.

Table 1 summarizes the mineralization observed in ST22-10. Intersections are expressed as downhole widths and are interpreted to be close to true widths. Visual estimates of sulfide type, quantity and habit should not be considered a substitute for laboratory assays. Laboratory assays are required to determine the widths and grade of mineralization as reported in preliminary geological logging.

Drilling Program Summary
Table 2 show details for drill holes completed at the Storm Project in the current program. A total 1,534.6m has been drilled to date.

Geological logging of the holes recently completed at the 2750N Zone – ST22-07 and ST22-08 – is being completed and a further announcement regarding this drilling will be made shortly. This shallow drilling is following up the significant historical copper intersections at the 2750N Zone, including 110m* at 2.45% Cu from surface (drill hole ST97-08), and 56.3m* @ 3.07% Cu from 12.2m (drill hole ST99-19). Significantly, the 2750N Zone copper mineralization remains open at depth and along strike with potential for ongoing drilling to further expand the significant volume of mineralization in this area.

The exploration phase of the program – highlighted by drill hole ST22-10 – has immediately delivered success with the discovery of a potentially major copper mineral system within the Storm Project. The early indications and scale of the mineralization intersected to date strongly suggest a stratiform sedimentary copper deposit model. Assays for ST22-10 are expected in the coming month.

Planned Program
Further diamond drilling and surface electromagnetics are planned to follow-up both the 2750N Zone and the new discovery. The drilling will also aim to define initial resources at the 4100N and 2200N Zones, where thick zones of high-grade copper mineralization have been intersected in historical drilling.

The EM will most likely consist of close spaced stations and moving loop configuration to better constrain the modelling. Downhole EM (DHEM) will also be used on all recent drill holes.

A detailed geophysical review will be completed with the aim of refining the current targets and planning follow-up surveys. Future surveys may include gravity and further EM surveys.

Investors can expect further news on the 2750N Zone drilling in the coming days.
