TORONTO, ON / ACCESSWIRE / September 20, 2024 / Aston Bay Holdings Ltd. (TSXV:BAY)(OTCQB:ATBHF) (“Aston Bay” or the “Firm”) is happy to supply an replace on drilling actions on the Storm Copper Challenge (“Storm” or the “Challenge”) on Somerset Island, Nunavut. The exploration program is being performed by American West Metals Restricted (“American West”), who’s the operator of the Challenge. Aston Bay and American West have shaped a 20/80 unincorporated three way partnership in respect of the Storm Challenge property, with Aston Bay sustaining a free carried curiosity till a choice to mine upon completion of a bankable feasibility examine.
Thomas Ullrich, Chief Govt Officer of Aston Bay, commented:
“The primary deep drill gap of the yr provides one other success to the 2024 exploration program at Storm. The fashion of copper mineralization intercepted, and its stratigraphic location is just like Cyclone – this can be the fault-offset southern portion of the deposit and will add to a possible future useful resource.
“Along with extensions to identified mineralization, this discovery highlights the invention potential of the deeper stratigraphic ranges within the Central Graben space, an expanse of over ten sq. kilometres. Each deep drill gap has hit copper mineralization at roughly the identical depth, and we proceed to enhance our geophysical modeling to hit thicker and higher-grade intercepts on this very giant and potential horizon.
“The worth of those deeper discoveries just isn’t restricted to the potential worth of the copper alone. The geophysical signature of exploration success that we receive from these drill holes might be fed again into the mannequin to additional refine our concentrating on for even higher copper intercepts at depth.”

DEEP COPPER SYSTEM PROSPECTIVITY CONFIRMED
Diamond drill gap ST24-01 was designed to check the stratigraphy of the Central Graben and the potential for brand new zones of copper mineralization throughout the ‘Deep Copper Horizon’ that was found throughout 2023 (see September 26, 2023, Aston Bay information launch).
The horizon intersected by ST24-01 is identical interpreted mineralized stratigraphic horizon that hosts the Cyclone Deposit at shallow ranges north of the North Graben Fault. Considerably, the drill gap intersected copper mineralization on the identical depth as encountered in each different widely-spaced drill gap throughout the giant Central Graben. The consistency of copper mineralization on this horizon highlights the laterally in depth and certain stacked nature of the deep copper system which now covers an space of over 10km2.
The intercepts in ST24-01 additional help the potential of Storm to host large-scale stratigraphic and structurally hosted high-grade copper deposits just like these within the Central African Copperbelt.

DRILL HOLE ST24-01 DETAILS
ST24-01 was drilled to a downhole depth of 385m and intersected a 22m-thick zone of breccia and vein fashion copper mineralization containing two sub-zones of stronger mineralization.
The higher 2m thick sub-zone incorporates veinlets of chalcocite hosted inside a reasonably fractured zone from 302.5m downhole.
The strongest zone of mineralization was intersected between 311m and 321m downhole, displaying the everyday sediment hosted copper mineralogical profile with a high-grade core of native copper and chalcocite with peripheral chalcopyrite and different much less copper-rich sulfide minerals (Desk 1 and Determine 3).
The copper mineralization is hosted close to the highest of a thick sequence of fractured dolomudstone of the Allen Bay Formation. The Allen Bay is the principle host of the copper mineralization throughout the Storm space, and the stratigraphic place close to the highest of the formation additionally hosts Cyclone, the most important deposit found thus far.
Mineralization encountered in ST24-01 may characterize the southern continuation of Cyclone throughout the down-thrown Central Graben block (Determine 4), demonstrating the invention potential for added giant and high-grade deposits. Additional, the intersection of copper mineralization on the identical stratigraphic place in each widely-spaced deep gap drilled thus far highlights the prospectivity of your entire 10km2 Central Graben. This massive and comparatively unexplored space is a key goal for follow-up drilling.

Concerning the Storm Copper and Seal Zinc-Silver Tasks, Nunavut
The Nunavut property consists of 173 contiguous mining claims overlaying an space of roughly 219,257 hectares on Somerset Island, Nunavut, Canada. The Storm Challenge contains each the Storm Copper Challenge, a high-grade sediment-hosted copper discovery (intersections together with 110m* @ 2.5% Cu from floor and 56.3* @ 3.1% Cu from 12.2m in addition to the Seal Zinc Deposit (intersections together with 14.4m* @ 10.6% Zn, 28.7g/t Ag from 51.8m and 22.3m* @ 23.0% Zn, 5.1g/t Ag from 101.5m). Moreover, there are quite a few underexplored and undrilled targets throughout the 120-kilometre strike size of the mineralized development, together with the Twister copper prospect the place 10 seize samples yielded >1% Cu as much as 32% Cu in gossans. The Nunavut property is now the topic of an 80/20 unincorporated three way partnership with American West (see “Settlement with American West” under for extra particulars).
Storm Discovery and Historic Work
Excessive-grade copper mineralization was found at Storm within the mid-Nineties by Cominco geologists conducting regional zinc exploration round their then-producing Polaris lead-zinc mine. A large chalcocite boulder present in a tributary of the Aston River in 1996 was traced to spectacular floor exposures of damaged chalcocite mineralization for tons of of metres of floor strike size at what grew to become named the 2750N, 2200N, and 3500N zones. Subsequent seasons of prospecting, geophysics and over 9,000 m of drilling into the early 2000s confirmed a big quantity of copper mineralization under the floor exposures in addition to making the blind discovery of the 4100N Zone, a big space of copper mineralization with no floor publicity.
Following the merger of Cominco with Teck in 2001 and the closure of the Polaris Mine, the Storm claims had been allowed to lapse in 2007. Commander Assets staked the property in 2008 and flew a helicopter-borne VTEM survey in 2011 however performed no further drilling. Aston Bay subsequently entered into an earn-in settlement with Commander and consolidated 100% possession in 2015. Commander retained a 0.875% Gross Overriding Royalty within the space of the unique Storm claims which was bought by Taurus Mining Royalty Fund L.P. in January 2024.
In 2016 Aston Bay entered into an earn-in settlement with BHP, who performed a 2,000-station soil sampling program and drilled 1,951m of core in 12 diamond drill holes, yielding as much as 16m* @ 3.1% Cu. BHP exited the settlement in 2017 and retains no residual curiosity within the undertaking. Aston Bay performed a property-wide airborne gravity gradiometry survey in 2017 and drilled 2,913m in 9 core holes within the Storm space in 2018 yielding a finest intercept of 1.5m* @ 4.4% Cu and 20.5m* @ 0.6% Cu.
Settlement with American West
On March 9, 2021, Aston Bay entered into an choice settlement with American West Metals Restricted (American West), and its wholly owned Canadian subsidiary Twister Metals Ltd., pursuant to which American West was granted an choice to earn an 80% undivided curiosity within the Challenge by spending a minimal of CAD$10 million on qualifying exploration expenditures. The events amended and restated the Possibility Settlement as of February 27, 2023, to facilitate American West immediately incomes an curiosity within the Challenge alongside its Canadian subsidiary with none change to the general business settlement between the events. The expenditures had been accomplished throughout 2023, and American West exercised the choice. American West and Aston Bay have shaped an 80/20 unincorporated three way partnership.
Below the three way partnership, Aston Bay shall have a free carried curiosity till American West has decided to mine upon completion of a bankable feasibility examine, which means American West might be solely accountable for funding the three way partnership till such choice is made. After such choice is made, Aston Bay might be diluted within the occasion it doesn’t elect to contribute its proportionate share and its curiosity within the Challenge might be transformed right into a 2% web smelter returns royalty if its curiosity is diluted to under 10%.
Current Work
American West accomplished a set loop electromagnetic (FLEM) floor geophysical survey in 2021 that yielded a number of new subsurface conductive anomalies. A complete of 1,534m had been drilled in 10 diamond drill holes within the 2022 season, yielding a number of spectacular near-surface intercepts together with 41m* @ 4.1% Cu in addition to 68m of sulfide mineralization related to a deeper conductive anomaly.
In April 2022, outcomes of beneficiation research demonstrated {that a} mineralized intercept grading 4% Cu from the 4100N space may very well be upgraded to a 54% Cu direct ship product utilizing normal sorting expertise. Additional beneficiation and metallurgical research are ongoing.
In April 2023, American West launched into a spring delineation drilling program utilizing a helicopter-portable RC drill rig in addition to conducting gravity and shifting loop electromagnetic (MLEM) floor geophysical applications.
The summer season 2023 program performed additional delineation drilling of the near-surface high-grade copper zones to advance them towards maiden useful resource estimates in 2024. Deep diamond drilling throughout 2023 found high-grade copper sulfides as much as 2.7% Cu at roughly 300m vertical depth (ST23-02), suggesting the potential for discovery of large-scale copper targets at depth.
Diamond drilling of latest high-priority deep MLEM targets, RC delineation drilling for useful resource growth and extra geophysical surveys are actually underway within the 2024 program. Metallurgical research and environmental baseline research are ongoing, with bulk sampling for prefeasibility-level processing deliberate for summer season 2024.
*Acknowledged drill gap intersections are all core size, and true width is predicted to be 60% to 100% of core size.
