TORONTO, ON / ACCESSWIRE / December 16, 2024 / Aston Bay Holdings Ltd. (TSXV:BAY)(OTCQB:ATBHF) ("Aston Bay" or the "Company") is pleased to provide an update on its Epworth Project ("Epworth") and the 2024 drilling and regional exploration activities at the Storm Copper Project ("Storm") in Nunavut.

Thomas Ullrich, Chief Executive Officer of Aston Bay,commented:

"It has been a successful year of exploration at both our Storm and Epworth Projects in Nunavut.

"At Storm, 22,475m of drilling was completed, exceeding expectations. Assay results demonstrated consistent copper grades, highlighting the excellent lateral continuity of the high-grade mineralization within the known zones and defining new discoveries and prospective areas. Work is well advanced on the maiden resource for Storm and the development study work. Reports on both fronts are expected in early 2025.

"At Epworth, we are impressed with the preliminary look at the property-wide MobileMT geophysical survey results and rock and lake sediment survey results. We are processing the geophysical results further and look forward to presenting a comprehensive compilation with the mapping and sampling results in January."

Epworth Project

A prospecting, rock sampling, and geological mapping program was conducted in 2024, including structural and stratigraphic studies by Dr. Elizabeth Turner. Nine claims totalling an additional 11,900 hectares ("ha") (119 square kilometres ("km²")) were added to the claims package, now totalling 89,000 ha (890 km2)

An 8,105 line-km airborne MobileMT survey covering the claim block commenced in late August and was completed in late September. Compilation of the assay results and additional geophysical data processing are underway. When all results are received, they will be integrated with historic work and released with a new interpretation in the New Year.

Storm Project

A total of 22,475m of drilling was conducted in 153 drill holes (19,879m in 138 Reverse Circulation ("RC") holes and 2,596m in 15 diamond drill holes) during the 2024 season. Assay results demonstrated consistent copper grades, highlighting the excellent lateral continuity of the high-grade mineralization within the known zones and defining new discoveries and prospective areas. Work is well advanced on a maiden resource constructed to Canadian Institute of Mining standards for a January 2025 release.

In addition to the drill hole results previously released, several scout holes were drilled to assist in interpreting the geologic framework in the Storm area. Results from these drill holes, the final results of the 2024 program, are presented below.

Stratigraphic and Reconnaissance Drilling

RC drill holes SR24-028, SR24-029, SR24-046, SR24-048, SR24-050, SR24-056, SR24-058, SR24-060, SR24-064, SR24-066, SR24-094, SR24-096, SR24-104, SR24-110, SR24-136 were completed within the Storm area during the 2024 drilling program (Figure 2). The drill holes were designed to assist with interpreting the stratigraphy and geological framework in several key areas. The drill holes were also used to help validate and assess the effectiveness of the geophysical surveys in the Storm area.

Drill holes SR24-046, SR24-050, SR24-060, and SR24-136 intersected minor, vein-hosted copper sulphides (Table 2).

The data from the drill holes has improved the geological understanding of the Storm Graben area and helped refine the geological model for the updated Mineral Resource Estimate (MRE) of the Storm Project.

Squall Drilling

RC drill holes SR24-108 and SR24-135 were also completed at the newly discovered Squall Prospect.

The holes were designed to test high-priority EM anomaly A3, which is visible in the data from both the 200m and 400m loop EM surveys (Figure 3). The coincident data suggested that the target may be located at a depth which crossed the designed detection ranges of the two surveys.

Drill hole SR24-108 achieved the maximum achievable depth of 182.9m downhole, limited by available drill rods. The drill hole is interpreted to have hit the eastern edge of the EM anomaly and intersected breccias and vein-hosted chalcocite assaying 2.4% Cu, 5g/t Ag in the last sampling interval of the hole (181.4 - 182.9m).

Follow-up drill hole SR24-135 was drilled to the east of SR24-108 and intersected 1.5m @ 0.5% Cu, 3g/t Ag from 163.07m downhole.

The EM anomaly and copper mineralization is interpreted to be related to a north-south orientated structure centred on drill hole SR24-108. This feature remains open, and future drilling will test the prospect to the north and south of the current drilling.

Update on previously released drilling

The first drill hole of the 2024 season, SR24-001, was drilled approximately 500m north of the Cyclone Deposit and was designed to test a Fixed Loop Electromagnetic (FLEM) target defined during exploration in 2022. The interpretation of the FLEM data suggested that the source of the anomaly could be located at depth but was weakly defined.

SR24-001 was drilled to a maximum achievable depth of 251.5m (limit of RC drill rods), encountering no copper sulphides or other lithologies that could confirm or explain the source of FLEM anomaly. The drill hole encountered weak pyrite (iron sulphides) mineralization at 125m and minor clay layers, but they were not in sufficient abundance to explain the EM response.

The 2024 Moving Loop EM (MLEM) survey was extended into the area to validate the FLEM anomaly but did not did not highlight any significant anomalies. The MLEM survey was optimized to search for conductive bodies between 0-250m depth, suggesting that the FLEM anomaly may be located at a deeper level.

Exploration drill hole SR24-005 was drilled to 251.5m and was designed to test an Induced Polarisation (IP) anomaly and stratigraphic section within the central graben area of Storm.

SR24-005 encountered a thick sequence of pyrite mineralization between 58m and 204m and is the likely source of IP anomalism in this area. The drill hole did not intersect the prospective copper horizon, which is interpreted to be below the extent of the drill hole and deeper than 250m in vertical depth.

About Aston Bay Holdings

Aston Bay is a publicly traded mineral exploration company exploring for high-grade critical and precious metal deposits in Nunavut, Canada and Virginia, USA.

The Company is currently exploring the Storm Copper Property and Cu-Ag-Zn-Co Epworth Property in Nunavut, as well as the high-grade Buckingham Gold Vein in central Virginia. The Company is also in advanced stages of negotiation on other lands with high-grade critical metals potential in North America

The Company and its joint venture partners, American West Metals Limited and its wholly-owned subsidiary, Tornado Metals Ltd. (collectively, "American West"), have formed a 20/80 unincorporated joint venture in respect of the Storm Project property, which hosts the Storm Copper Project and the Seal Zinc Deposit. Under the unincorporated joint venture, Aston Bay shall have a free carried interest until American West has made a decision to mine upon completion of a bankable feasibility study, meaning American West will be solely responsible for funding the joint venture until such decision is made. After such decision is made, Aston Bay will be diluted in the event it does not elect to contribute its proportionate share and its interest in the Storm Project property will be converted into a 2% net smelter returns royalty if its interest is diluted to below 10%.
