Drill testing of new high-priority EM conductors also planned
TORONTO, ON / ACCESSWIRE / June 22, 2022 / Aston Bay Holdings Ltd. (TSXV:BAY) (OTCQB:ATBHF) (“Aston Bay” or the “Company”) is pleased to announce that the Company’s exploration and earn-in partner, American West Metals Limited (“American West”), has released details of the planned drilling and exploration activities at Aston Bay’s high-grade Storm Copper Project (“Storm” or the “Project”) on Somerset Island, Nunavut.
A major diamond drilling program is scheduled to commence at Storm next month to test key resource and exploration targets. This drilling program will be the first since American West became project operator under the option agreement with Aston Bay. American West has an option to earn an 80% interest in the Storm Project. APEX Geoscience Ltd. will manage and execute the program.

Diamond drilling is planned to commence at Storm in July 2022 to test high-grade copper targetsDrilling will focus on resource definition at the high-grade 2750N ZonePrevious intersections at the 2750N Zone include 110 metres (m)* @ 2.45% copper (Cu) from surface and 56.3m* @ 3.07% Cu from 12.2mPotential to also delineate additional zones of copper mineralization with drill testing of new, high-priority EM conductorsA bulk sample of copper mineralization at Storm will be acquired during the program for second-phase direct shipping product (DSP) and beneficiation test work; initial ore sorting supports the potential to produce a DSP with a grade >53% Cu
The resource definition drilling will begin at the 2750N Zone where historical drilling has encountered significant copper mineralization, 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). The 2750N Zone copper mineralization is open at depth and along strike.
Drilling will also test a number of high-priority electromagnetic (EM) conductors that were identified by the 2021 fixed loop electromagnetic (FLEM) survey completed by American West over the Storm Project area. The survey identified multiple near-surface anomalies, some of which are coincident with outcropping copper occurrences, that are consistent with EM responses of known occurrences of massive chalcocite mineralization on the Storm property.
The 2021 survey also identified several large, flat-lying EM conductors that may represent a deeper, stratigraphic source to the near-surface mineralization. These anomalies present compelling targets for the discovery of a major sedimentary copper mineral system.
“We are excited to have our earn-in partner American West so swiftly advance the Storm Project,” stated Thomas Ullrich, CEO of Aston Bay. “The ground geophysical program completed last season has been instrumental in defining high-priority drill targets for this year, and the outstanding result of a >53% Cu direct ship product from ore-sorting tests conducted over the winter is conducive to low-impact mining.
“Storm has more than 14,000 metres of historical drilling with significant high-grade copper intercepts. The current program is designed to unlock the value of these intercepts by moving toward a resource that could support a mining proposal, as well as by expanding on these known areas of mineralization. We will also continue to drill for discovery in unexplored areas, targeting untested anomalies that may represent sizable zones of undiscovered high-grade copper mineralization.”

RESOURCE DEFINITION DRILLING
Resource definition this year will initially focus on defining potential shallow resources within the 2750N Zone.
Historical drilling within the 2750N Zone has encountered thick intervals of high-grade copper mineralization, 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). Given the outstanding width of these intervals and the distance between drill holes (>100m), extension and infill drilling in the 2750N Zone gives the potential opportunity to quickly define large volumes of further copper mineralization.
Over 1,500 metres of drilling is initially planned in and around the 2750N Zone, with hole depths between 100-150m due to the shallow nature of mineralization.
Initial ore sorting test work on the shallow copper mineralization at Storm supported the production of a direct ship product grading 53% Cu (see news release dated April 11, 2022).
The excellent results from the ore-sorting test work suggest that a shallow, high-grade resource is likely to be well suited to a low-footprint direct ship product (DSP) mining operation.
EXPLORATION DRILLING – 2021 FIXED LOOP EM (FLEM) SURVEY
American West completed a large fixed loop EM (FLEM) survey over the Storm Copper Project area in 2022 (see news release dated December 13, 2021).
Historical EM surveys have successfully identified several strong conductive anomalies that are associated with known copper mineralization at Storm. The high-powered 2021 survey was designed to better define these historical anomalies, highlight potential extensions to the known copper mineralization and to also identify potential new targets.
The 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 2).
Shallow EM conductors
Seven shallow conductors were identified during the 2021 FLEM survey that are interpreted as likely to represent untested zones of massive chalcocite mineralization. These anomalies are favorably situated along, or in close proximity to, the bounding faults of the Storm graben, and in areas of elevated density (Figure 2).
Importantly, the conductors east of the 2200N and 2750N Zones are also associated with significant copper in soil geochemical anomalies and outcropping copper mineralization.
With only very limited drilling into some of these areas of anomalism, the newly defined conductors present a number of compelling new and untested drill targets that will be tested during the upcoming drilling program.

Deep EM conductors
Seven untested deeper conductors of interest were also identified during the 2021 survey (Figure 2, red rectangles). Six of the seven anomalies are located proximal to the bounding faults of the Storm graben.
The geometry and mostly gentle dips of the modeled deep EM conductors suggest that they may be related to stratiform type targets and may be indicative of traditional sedimentary type copper mineralization at depth. Given the highly resistive nature of the host geology (dolomites), even subtle conductors are considered to be highly prospective when combined with coincident geochemical or airborne gravity anomalies.
One of these is a large (>750m in strike) conductive anomaly associated with the 4100N Zone where previous high-grade intersections include 15m* @ 3.88% Cu from 72.4m (drill hole ST99-47)*. A large conductive anomaly was also recognized below the 2750N and 2200N Zones.
These present as compelling large-scale exploration targets that may represent the source of the near-surface high-grade copper already confirmed by shallow drilling. These new targets will be tested as part of the 2022 drill program.
PROGRAM TIMING
The diamond drilling at Storm is expected to commence in early July, with the logistics and final planning currently underway. The results of the drilling program are expected to be released regularly given the highly visual nature of the copper mineralization and host geology.

The Nunavut property consists of 117 contiguous mining claims and six prospecting permits covering an area of approximately 302,725 hectares on Somerset Island, Nunavut, Canada.
The Storm Project comprises both the Storm Copper Project, a high-grade copper discovery (intersections including 110m* @ 2.45% Cu from surface and 56.3m* @ 3.07% Cu from 12.2m) as well as the Seal Zinc-Silver Deposit (intersections including 14.4m* @ 10.58% Zn, 28.7g/t Ag from 51.8m and 22.3m* @ 23% Zn, 5.1g/t Ag from 101.5m).
There are numerous underexplored targets within the 120-kilometre (km) strike length of the mineralized trend, including the Tornado copper prospect where 10 grab samples yielded >1% Cu up to 32% Cu in gossans.
American West has an option to earn an 80% interest in the Storm Project.
*Stated drill hole intersections are all core length, and true width is expected to be 60% to 90% of core length.
