Aston Bay and American West Metals Confirm New Thick Copper Intercepts at Cyclone and Lightning Ridge as Drilling Accelerates at the Storm Copper Project, Canada
Aston Bay Holdings and American West Metals have confirmed new thick copper intercepts at the Storm Copper Project. The 2024 summer drilling program has accelerated, with over 4,450 meters drilled across 30 RC holes. Diamond drilling has also started.
Recent drilling at Cyclone and Chinook aims to expand known resources, while Lightning Ridge exploration has confirmed significant copper sulfide mineralization. Drill holes at Cyclone show a robust, continuous copper deposit with potential for resource delineation. Visual results from 16 drill holes indicate a 100% hit rate for copper sulfides. Assays for remaining holes are pending.
At Lightning Ridge, drill holes SR24-014 and SR24-016 show up to 30.5m and 21.3m of visual copper sulfide mineralization, respectively. Cyclone drilling has intersected thick intervals of semi-massive sulfides, supporting significant growth potential. Further exploration at Thunder and Chinook is ongoing.
The drilling program aims to complete 20,000 meters this season, with significant potential for new discoveries in the underexplored Central Graben area.
- Over 4,450 meters drilled, indicating accelerated exploration progress.
- 100% hit rate for copper sulfides in 16 drill holes, suggesting successful mineralization.
- Drill hole SR24-009 intersected 32 meters of strong visual copper sulfides, supporting significant growth potential.
- Cyclone drilling confirms robust and continuous copper mineralization, enhancing resource potential.
- Assay results for recent drilling are still pending, creating uncertainty about the actual mineral grades.
30 RC drill holes now completed with diamond drilling now also underway
The 2024 summer drilling program continues to accelerate with more than 4,450 metres ("m") now completed
The recent drilling has targeted expansion at the Cyclone and Chinook Prospects, and delineation drilling Lightning Ridge discovery and Thunder Prospect
Visual results have been received for 16 of the Lightning Ridge and Cyclone Deposit drill holes which confirm a
100% hit rate for copper sulfides; visual results for drilling at Thunder and Chinook are pending
Lightning Ridge Prospect:
Drill hole SR24-014 has intersected a combined total of 30.5m of visual copper sulfide mineralization within three zones from 57.9m downhole
Drill hole SR24-016 has intersected a combined total of 21.3m of visual copper sulfide mineralization within three main zones from 38.1m downhole, including 5m of very strong copper sulfide mineralization from 44m downhole
Copper mineralization at the Lightning Ridge zone has now been defined over a strike of 150m, with excellent potential to expand further
Cyclone Deposit:
Visual results have been received for 13 drill holes, including several outside of the current mineralization footprint, with all drill holes intersecting visual copper sulfides
Drill hole SR24-009 was drilled approximately 80m to the south-west of the Cyclone Deposit and has intersected 32m of strong visual copper sulfides from 85.3m downhole
Drill holes SR24-011 and SR24-013 have intersected thick intervals of semi-massive sulfides within the southern part of the current known mineralization envelope
Drilling at the Cyclone Deposit continues to confirm the robust and continuous nature of the copper mineralization supporting the potential for delineation of a future resource and outstanding growth potential
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 sulfides. Portable XRF is used as an aid in the determination of mineral type and abundance during the geological logging process.
TORONTO, ON / ACCESSWIRE / July 10, 2024 / Aston Bay Holdings Ltd. (TSXV:BAY)(OTCQB:ATBHF) ("Aston Bay" or the "Company") is pleased to present an update on drilling and exploration activities currently underway at the Storm Copper Project ("Storm" or the "Project") on Somerset Island, Nunavut. The program is being conducted by American West Metals Limited ("American West"), who is the operator of the Project. Aston Bay and American West have formed a 20/80 unincorporated joint venture in respect of the Storm Project property, with Aston Bay maintaining a free carried interest until a decision to mine upon completion of a bankable feasibility study.
Thomas Ullrich, Chief Executive Officer of Aston Bay, commented:
"The 2024 exploration program has ramped up production and we are on track to drill the proposed 20,000 metres this season.
"The summer phase of drilling is hitting visual copper mineralization in every hole, expanding the already large zone of high-grade copper mineralization at Cyclone and confirming additional mineralization around last year's discovery at Lightning Ridge. Most exciting for me is the intersection of a thick zone of copper sulfide mineralization across the fault from Cyclone in the down-dropped Central Graben. This extensive area holds the potential for significant additional discoveries concealed below the surface in this down-faulted block."
DRILL PROGRAM ACCELERATING AT STORM
A total of 30 drill holes (for approximately 4,453m) have now been completed during the 2024 drilling program, with drilling ongoing. Assay results were received from the five exploratory Reverse Circulation ("RC") drill holes from the spring phase of the program, which confirmed exploration success at the Gap prospect (see Aston Bay July 2, 2024, news release). Assay results from the remainder of the current drilling, including the 3,460m drilled since July 1, are pending. Drilling is ongoing with 20,000m planned.
The recent drill holes have been completed at the Cyclone, Chinook, Thunder, and Lightning Ridge high-grade copper prospects. The visual results from 16 of these drill holes have now been received, with all holes intersecting visual copper sulfides. The mineralogy and presence of copper has been confirmed with portable XRF analysis.
The drilling at the Cyclone Prospect is designed to expand and infill an upcoming maiden mineral resource estimate for the Storm Project that is currently being constructed to CIM standards and to explore the margins of the deposit for additional resources.
Figure 1: Reverse Circulation (RC) drilling underway at the Cyclone Deposit, Storm Project, Nunavut.
All of the reported infill drill holes have intersected thick intervals of visual copper sulfides, including semi-massive sulfides, highlighting the outstanding continuity of the mineralization at Cyclone.
Exploration drilling outside of the known Cyclone mineralization has also intersected thick intervals of strong visual copper mineralization, confirming the excellent potential for growth to the south-west, east, and north of the deposit.
The initial Lightning Ridge drilling has successfully confirmed the continuity and likely geometry of the high-grade mineralization. The steeply dipping copper mineralization (discovery hole SR23-52 intersected 30.4m @
The 2024 drill program is continuing with two RC drill rigs and single diamond drill rig. The excellent production of the drilling achieved to date puts the program on track to complete the planned 20,000m of drilling.

LIGHTNING RIDGE COPPER PROSPECT EXTENDED
The Lightning Ridge Prospect is located to the south of the Chinook Prospect. The high-grade copper zone was discovered with exploration drilling during 2023 in which drill hole SR23-52 intersected 15.2m @
Outcropping massive chalcocite is visible at surface and in boulders at the base of a large E-W oriented gully (Figure 4). The proximity to the gully and the style of mineralization is strongly suggestive that the mineralization is fault-related and steeply dipping, as is seen at the nearby Chinook and Corona copper prospects.
The initial 2024 drilling at Lightning Ridge included three drill holes designed to test the strike extent and confirm the geometry of the high-grade mineralization intersected in SR23-52 (Figure 3).
The visual results have now been received and show that the drill holes along strike of the initial discovery hole have intersected strong visual copper sulfides. The known strike extent of the Lightning Ridge is now interpreted to be over 150m.
The third drill hole was drilled beneath SR23-52 and what is interpreted to be parallel to the zones of high-grade mineralization. The drill hole also intersected visual copper sulfide mineralization and other mineralogy that supports the interpretation that this third hole is located on the margin of the main copper zone. See below for details.

DRILL HOLE SR24-014 AND SR24-016 DETAILS
RC drill hole SR24-014 was drilled to a depth of 119m and completed to the west of discovery drill hole SR23-52 (Figure 3).
SR24-014 has intersected three main zones of visible chalcocite- and chalcopyrite-dominant mineralization, correlating with the multiple copper zones encountered in drill hole SR23-52.
Drill hole SR24-016 was drilled to a depth of 129.5m and is located east of drill hole SR23-52. Three distinct zones of copper sulfide mineralization were also intersected, including a strongly mineralized zone between 102-106m downhole.

DRILL HOLE SR24-018 DETAILS
Drill hole SR24-018 was drilled to a depth of 149.4m and below discovery drill hole SR23-52.
The drill hole intersected a thin interval of minor copper sulfides from a depth of 146.3m downhole, and multiple zones of visible pyrite and copper oxides. This mineral assemblage is typical of peripheral copper mineralization in sed-hosted copper systems, supporting the interpretation that the step-back position of the drill hole is on the southern margin of the east-west trending copper zone at Lightning Ridge.
The copper sulfides in all of the Lightning Ridge drill holes are hosted in veinlets and breccias within the Allen Bay dolomudstones. The main zones of copper mineralization are thought to be related to the steeply dipping fault architecture in the southern graben area. Lightning Ridge is one of six known high-grade copper zones within this under-explored area, with over 10km of prospective faults yet to be explored.

CYCLONE EXPANSION POTENTIAL CONFIRMED WITH THICK COPPER INTERSECTIONS
Delineation drilling at the Cyclone Prospect is continuing and the visual results from drill holes SR24-007, SR24-009, SR24-011, SR24-013, SR24-015, SR24-017, SR24-19, SR24-021, SR24-023, SR24-024, SR24-025, SR24-026 and SR24-027 have been received. Drilling is designed to expand and infill an upcoming maiden mineral resource estimate for the Storm Project that is currently being constructed to CIM standards.
The visual results continue to demonstrate the excellent lateral continuity of the high-grade mineralization and confirm the expansion potential of Cyclone to the south-west, east, and north.

CYCLONE AREA DRILLING
Drill holes SR24-011, SR24-013, SR24-015, SR24-017, SR24-19, SR24-021, SR24-023, SR24-024, SR24-025, SR24-026 and SR24-027 were drilled to expand and infill an upcoming maiden mineral resource estimate for the Storm Project that is currently being constructed to CIM standards. All drill holes have intersected thick intervals of visual copper sulfide mineralization, hosted within dolomite of the Allen Bay Formation.
The mineralization encountered within the drilling to date is comprised of zones of visual sulfides hosted within a broad mineralized package of what is interpreted to be mostly vein- and fracture-style mineralization.
The dominant visible copper sulfide mineral observed within the drill holes to date is chalcocite, with minor bornite and chalcopyrite on the margins of the mineralized intervals and within veins. Minor native copper and copper oxides (mostly malachite and cuprite, meteoric weathering products) are also present. Portable XRF analyzers are used to assist the geological logging.
Chalcocite is an important copper mineral due to its high copper content (up to

DRILL HOLE SR24-009 DETAILS
SR24-009 was drilled approximately 80m south-west of the Cyclone Deposit and to a downhole depth of 120.4m. The drill hole was designed to test for potential extensions to the existing known copper mineralization.
SR24-009 has intersected a single, 32m thick zone of visual copper sulfide mineralization between 85.3m and 117.4m downhole (Figure 6). The chalcopyrite dominant mineralization consists of a strongly mineralized zone between 99.1m and 117.4m downhole.
Both the Allen Bay host rock and copper mineralization in SR24-009 are displaced downward relative to the Cyclone Deposit at this location, south of the fault that marks the northern edge of the Central Graben (Figures 2 and 6). This large block of downward-faulted rock within the Central Graben is defined by faults that are spatially associated with the majority of the copper mineralization at Storm and are the likely plumbing system for mineralizing fluids. Confirmation of downward-displaced copper mineralization in this drill hole highlights the potential for the Central Graben to host significant copper mineralization that is not seen at the surface.
The thickness of visual copper mineralization in this large step-out across the fault from the large body of known copper mineralization at Cyclone highlights the significant potential for additional copper mineralization to the south-west of Cyclone and elsewhere in the very large but underexplored Central Graben.

About the Storm Copper and Seal Zinc-Silver Projects, Nunavut
The Nunavut property consists of 173 contiguous mining claims covering an area of approximately 219,257 hectares on Somerset Island, Nunavut, Canada. The Storm Project comprises both the Storm Copper Project, a high-grade sediment-hosted copper discovery (intersections including 110m* @
Storm Discovery and Historical Work
High-grade copper mineralization was discovered at Storm in the mid-1990s by Cominco geologists conducting regional zinc exploration around their then-producing Polaris lead-zinc mine. A massive chalcocite boulder found in a tributary of the Aston River in 1996 was traced to impressive surface exposures of broken chalcocite mineralization for hundreds of metres of surface strike length at what became 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 significant amount of copper mineralization below the surface exposures as well as making the blind discovery of the 4100N Zone, a large area of copper mineralization with no surface exposure.
Following the merger of Cominco with Teck in 2001 and the closure of the Polaris Mine, the Storm claims were allowed to lapse in 2007. Commander Resources staked the property in 2008 and flew a helicopter-borne VTEM survey in 2011 but conducted no additional drilling. Aston Bay subsequently entered into an earn-in agreement with Commander and consolidated
In 2016 Aston Bay entered into an earn-in agreement with BHP, who conducted a 2,000-station soil sampling program and drilled 1,951m of core in 12 diamond drill holes, yielding up to 16m* @
