Highlights:
- The 2025 drill program is set to begin. A pipeline of large-scale exploration targets prioritized for drilling includes:
- Cirrus Deeps - high-priority EM target below the Cirrus Deposit with a stratigraphic setting similar to Cyclone will be the first target to be tested with diamond drilling
- Cyclone Deeps - potential continuation of the large Cyclone Deposit at depth with reconnaissance drill intercepts such as 10 metres ("m") @ 1.2% copper ("Cu") from 311m (including 0.5m @ 3.7% Cu from 315.5m), ready for follow-up with diamond drilling
- Resource Expansion - several discoveries near the footprint of the Mineral Resource Estimate ("MRE") will be followed up, including the Gap Prospect, which contains a strong EM anomaly confirmed with drilling that returned 20m @ 2.3% Cu from 28m, and the Squall and Hailstorm Prospects
- Tornado/Blizzard - located 5km east of the Storm copper deposits, the area hosts a 3.2km x 1.5km geochemical copper anomaly and two large electromagnetic ("EM") plates yet to be drilled
- Midway - discovered by a single historical drill hole that intersected a total of 58m of visual copper sulfide, located approximately 5km to the west of the Storm MRE area, to be drilled
- Geophysics to generate new targets. An extensive airborne Mobile Magneto-Telluric ("MobileMT") survey is planned early in the season for the Storm MRE area and other areas of interest along the 110km prospective copper horizon, with results expected to inform drill targeting and prioritization this season.
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.
Thomas Ullrich, Chief Executive Officer of Aston Bay, commented:
"We are excited to begin another field season at Storm. The reverse circulation drill rig will work on adding to the resource and target near-surface exploration targets, while the diamond drill rig will focus on the deeper exploratory holes.
"In addition to the compelling targets generated in previous geophysical programs, we are very excited to be flying a comprehensive MobileMT survey at Storm. This is the same survey that has successfully delineated large conductive targets at our Epworth property. The significant contrast in the conductive properties of the mineralized rock versus the host rock at Storm is ideal for MobileMT, and its utilization of natural-source energy from within the Earth should help define deeper targets that may have eluded previous methods. These new targets will be ready for drilling this season.
"Investors can also look forward to the completion of a Preliminary Economic Analysis for the near-surface mineralization at Storm, currently underway. We are also working up drill targets for our Epworth copper project, also in Nunavut, for a potential late-season drill program."

INITIAL DIAMOND DRILL PLAN
The first diamond drill targets to be tested in the Storm MRE area are Cirrus Deeps and Cyclone Deeps (Figure 2). The drilling aims to follow up earlier intersections of high-grade copper mineralization and build evidence for the large-scale copper potential at depth, which could rapidly expand the copper endowment within the Storm MRE area.
Subsequent diamond drilling will continue to test high-priority geophysical anomalies and regional exploration targets. These will include the Tornado, Blizzard, Midway areas and any new targets defined by the upcoming MMT survey.

Cirrus Deeps
Diamond drill hole ST24-03 was designed to target a 1,300m x 500m MLEM anomaly (Figure 3 & 5) which is bounded by a series of large EM plates (approximately 350m to top, conductance ~40-60 siemens, moderate ~40-60° S/SW dip, striking ~WNW-ESE) at its northern edge. The EM anomalies are located below the Cirrus Deposit and the Gap high-grade copper prospect, and are interpreted to be proximal to the Southern Graben Fault.
This location in the Allen Bay Formation immediately below the Cape Storm Formation is the same stratigraphic location as Cyclone. In addition to the potential for flat-lying stratigraphic mineralization like Cyclone, the target is located along a fault zone similar to the well-mineralized Chinook Deposit. These anomalies may indicate a considerable, connected accumulation of copper within the Central Graben area. Similar EM targets drilled elsewhere in the Storm copper belt have been confirmed as high-grade copper mineralization.
Figure 3: NE-SW geological section view through ST24-03 (looking NW) showing the Cirrus Deposit, interpreted Southern Graben Fault and modelled MLEM conductors. The planned drill hole depth is 650-700m.
ST24-03 has currently been drilled to a downhole depth of 414m (planned depth of 600-700m) and intersected several zones of fracturing and sporadic copper sulfides (Figure 3) in the upper portion of the hole, with increased fracturing at depth. Fracturing and voids in the rock are positive indications since permeability and open spaces are required for efficient mineralization in the sediment hosted copper model.
The drill hole will be the first diamond hole completed in the 2025 drill program.
Cyclone Deeps
High-grade copper mineralization has been discovered at depth, offset to the south of the Cyclone Deposit (Figure 4). The Cyclone Deeps intersection of 10m @ 1.2% Cu (drill hole ST24-01) displays a typical sediment hosted copper mineralogical profile with a high-grade core of native copper and chalcocite (including 3m @ 2.2% Cu) with peripheral chalcopyrite and other less copper-rich sulfide minerals.
The copper mineralization is hosted near the top of a thick sequence of fractured dolomudstone of the Allen Bay Formation. The Allen Bay is the main host of the known copper mineralization within the Storm area, and the stratigraphic position near the top of the formation also hosts Cyclone, the largest deposit discovered to date. This mineralization may represent the offset southern portion of the faulted Cyclone Deposit and presents an exceptional opportunity to add significant volume to the current resources. This prospective horizon extends for over 5km in the immediate Storm area.

INITIAL REVERSE CIRCULATION DRILL PLAN
Reverse Circulation ("RC") drilling will be used to test near-surface (<250m depth) resource upgrade, resource expansion, and exploration targets.
The first phase of drilling will commence at the Thunder, Lightning Ridge, and Corona Deposits before moving on to The Gap, Squall and Hailstorm Prospects (Figure 2). All of these opportunities have the potential to add significant mineral resources to the Storm Project, with high-grade mineralization similar to the known deposits already discovered.
Subsequent RC drilling will aim to test other nearby and regional exploration targets, which include the Tornado and Blizzard areas, and numerous untested geochemical, Electromagnetic (EM) and Induced Polarization (IP) anomalies.
The Gap Prospect is a 500m-long zone located between the Corona and Cirrus Copper Deposits (Figure 2), where multiple drill holes have intersected high-grade copper sulfides (including 1.5m @ 4.4% Cu, 9.8g/t Ag from 39m, and 2m @ 2.5% Cu from 74m downhole in AB18-09, and 20m @ 2.3% Cu, 3.3g/t Ag (Including 8m @ 5.3% Cu, 6.4g/t Ag) from 28m in SR24-003.
The Squall and Hailstorm Prospects are located immediately south of the southern graben fault and collectively extend 1.8km northwest along strike of the Corona Deposit (see Figure 2).
Drilling at Squall during the 2024 season intercepted 1.5m @ 2.36% Cu, 5.0g/t Ag from 181.4m (SR24-108) at the end of the hole, whilst surface geochemistry at Hailstorm has identified a 250m x 250m copper anomaly that remains open to the south (Figure 5).

Mobile Magneto-Telluric (MobileMT) Survey
A regional-scale MobileMT survey is planned to cover the Storm and wider exploration areas during the 2025 program (Figure 6). MMT utilizes natural source energy to capture a broader range of EM frequencies than the techniques used at Storm to date. The survey is designed to show a greater contrast between the host rocks and potential accumulations of conductive material (i.e. metalliferous sulfide) with improved spatial and depth resolution. This is potentially very useful in delineating deeper (>200m) occurrences of copper sulfide at Storm, where the resistive host rocks cause a decreased signal-to-noise ratio and decreased confidence in interpretation with depth in the historical geophysics.
The initial MobileMT survey will be completed over the Midway-Storm-Tornado area as an orientation survey to determine the response of the known deposits before extending the survey into more regional areas. The survey will begin in the coming week, allowing results to inform drill targeting and prioritization this season.
