Success of Geophysical Surveys:
A number of geophysical techniques have been used to explore the Storm and Seal Project areas and wider tenure since the first copper and zinc discoveries in the early 1990’s.
Electromagnetics were proven to be an effective exploration tool when the Storm area was first surveyed with airborne EM in 1997. This survey determined a clear relationship between known, outcropping copper mineralization with newly identified EM anomalies. Subsequent higher resolution airborne and surface EM surveys, backed up by drilling, further confirmed this association.
The 2021 EM surveys utilised a time domain electromagnetic (TDEM) system featuring low noise / high power and were completed using a fixed conventional loop configuration. A total area of approximately 18km2 was completed for 945 stations, with a nominal station spacing of 100m at the Storm Copper prospect and 50m at the Seal Zinc deposit. Infills on a number of prospects at Storm were completed at 50m spacings.
The results of three EM survey lines over the high-grade zinc-silver Seal deposit indicated that the known mineralization at Seal is not visible to this particular EM system, and therefore no anomalies could be identified in the vicinity of the deposit. While this work does not preclude other EM systems effectively being used to explore around Seal, the nearby Tier 1 Polaris Zinc-Lead deposit was discovered using gravity surveys, and this will continue to be the preferred geophysical tool for testing the extensive Seal stratigraphic horizon.
Further ground EM surveys will be planned for the 2022 season to screen the Tornado and Blizzard areas. These areas lie east along strike from Storm and have existing copper in soil and gravity (AGG) anomalies.
Methodology and QA/QC
The 2021 Storm Project surface time domain electromagnetic (TDEM) survey was completed using a fixed conventional loop configuration (in and out of loop), with a nominal station spacing of 100 m with 50 m infills at the Storm Copper prospect, and 50 m at the Seal Zinc deposit. Storm loops 1 through 10 were sized 1,000 m by 1,000 m oriented at a 0° azimuth. Seal loop 11 was sized 400 m by 200 m oriented at a 45° azimuth. A Geonics TEM57 MK-2 transmitter with TEM67 boosters was used in conjunction with a portable Honda generator to produce a maximum output of 1.2 kW or 20 A or 60V. The Storm loops carried a current of 13-14 A and the Seal loop carried a current of 19.5 A. An ARMIT Mk2.5 sensor and EMIT SMARTem 24 receiver were used to measure and collect vertical (Z) and horizontal (X and Y) components of the B-Field and its partial derivative dB/dt. EMIT Maxwell software was used for QC, data processing, modelling, presentation and interpretation of the results. Seequent Montaj software was used for additional interpretation and to produce coloured maps.
Prior to the survey, the transmitter and generator were checked for maximum output using calibrated loads. Receivers were calibrated and synchronized to the transmitter prior to and during data acquisition. Polarity of the primary field components was checked and corrected, as necessary. All data were inspected, validated, and inspected for abnormal or problematic noise. No abnormal or problematic noise was observed.
About the Storm Project
The Storm Project consists of 117 contiguous mining claims and 6 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 sediment hosted 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 Deposit (intersections including 18.8m @ 10.58% Zn, 28.7g/t Ag from 51m and 22.1m @ 6.62% Zn, 27.1g/t Ag from 27.1m). As well, there are numerous underexplored targets/prospects within the 120km 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 Metals Limited has an option to earn an 80% interest in the Storm Project (see March 9, 2021, Aston Bay press release), and is sole funding the exploration activity currently underway.

About Aston Bay Holdings Limited
Aston Bay is a publicly traded mineral exploration company exploring for gold and base metal deposits in Virginia, USA, and Nunavut, Canada. The Company is led by CEO Thomas Ullrich with exploration in Virginia directed by the Company's advisor, Don Taylor, the 2018 Thayer Lindsley Award winner for his discovery of the Taylor Pb-Zn-Ag Deposit in Arizona.
The Company has acquired the exclusive rights to an integrated dataset over certain prospective private lands and has signed agreements with timber and land companies and other private landowners which grants the company the option to lease the mineral rights to over 10,000 acres of land located in central Virginia. These lands are located within a gold-copper-lead-zinc mineralized belt prospective for mesothermal gold deposits and Virginia gold-pyrite belt deposits, as well as VMS, sedimentary exhalative (SEDEX) and Broken Hill (BHT) type base metal deposits. Don Taylor, who led the predecessor company to Blue Ridge and assembled the dataset, has joined the Company’s Advisory Board and will be directing the Company’s exploration activities for the Blue Ridge Project. The Company is actively exploring the Buckingham Gold and Mountain Base Metals Projects in Virginia and is in advanced stages of negotiation on other lands in the area.
The Company is also 100% owner of the property Storm Project, which hosts the Storm Copper Project and the Seal Zinc Deposit and has been optioned to American West Metals Limited.
