EXPLORING FOR LARGE, HIGH-GRADE, SEDIMENT-HOSTED COPPER AND ZINC DEPOSITS IN THE CANADIAN ARCTIC
Copper and Zinc
Aston Bay (TSX.V: BAY) is a Canadian listed explorer targeting large, high-grade, sediment-hosted copper and zinc deposits in Nunavut, Canada. Aston Bay’s 100% owned flagship project ‘Aston Bay Property’ is located on western Somerset Island, Nunavut, which neighbours Teck’s profitable past-producing Polaris (Pb-Zn) Mine 200km north. The ‘Aston Bay property’ hosts the Storm Copper Project and the Seal Zinc Prospect, with historical drilling confirming the presence of sediment-hosted copper and zinc mineralization.

- 8,000m drill program planned.
- Falcon Plus Airborne Gravity Gradiometry survey conducted by CGG Multi-Physics.
- Institutional Investor backed company.
- 100% owned property 4,145 km2.
- 9,000m previous drilling with high-grade Cu and Zn.
- Located in an under-explored sediment hosted copper belt: “Elephant Country”.
- Multiple Cu and Zn showings along >100km strike length of correlative host rocks.
- Along strike from past- producing Polaris zinc mine (21 Mt @ 14% Zn).
- Similar mineralogy, zonation, grade and structural setting to copper deposits such as Komoa-Kakula and zinc dpeosits such as Polaris and Kipushi.
- Seal Zinc
- Storm Copper
- Typhoon Zinc
Somerset Island, Nunavut, Canada
Aston Bay Strategy
- Aston Bay is in search of Congo-style Copper and Polaris-size Zinc on the Aston Bay Property.
- Mineralogy, zonation, grade and structural setting for both Storm Copper and Seal Zinc are similar to sediment-hosted copper deposits such as Kamoa-Kakula located in the Congo, as well as zinc deposits such as Polaris, located 200km to the north, and Kipushi, also in the Congo. Explored at shallow levels only by several companies, 1994-2001.
- High-grade copper and zinc mineralization at surface, confirmed by over 9,000 metres of historical drilling at Storm (e.g. 110 m of 2.45% Cu) and Seal (e.g. 18.8 m of 10.6% Zn).
- Proven surface mineralization at Storm and Seal indicates a robust ore-forming system, but the flat-lying rocks easily conceal potential sediment-hosted deposits.
- Density anomalies delineated in the recently acquired property wide gravity survey provide the targets for potential prize: concealed sediment-hosted copper and zinc deposits.
- Located approximately 20 km from tidewater at Aston Bay.
- The geologic setting, mineralogy and zonation suggest affinities to sediment-hosted copper deposits.
- Hypogene copper mineralization present at surface and identified to a depth of at least 100 metres in the form of chalcocite, bornite, covellite and chalcopyrite.
- Discovered in 1994.
- Historic work on the property was undertaken by Cominco Ltd. (now Teck Resources Ltd).
- Sixty-seven holes (9,032.5 m) were drilled at Storm between 1996 and 2000.
- Four separate zones of copper mineralization — 2200N, 2750N, 3500N, and 4100N Zones — all of which remain open both laterally and vertically.
- 3,970 line-km of VTEM airborne survey was completed over the property in 2011.
- Historic drilling at Storm Copper highlights include:
>> 110 metres (m) core length grading 2.45% copper (Cu) from surface at the 2750N Zone
>> 56m core length grading 3.07% Cu from 12.2m depth at the 2750N Zone
>> 49m core length grading 1.79% Cu starting at surface at the 2200N Zone
>> 16m core length grading 3.07% Cu, starting at 93 m from surface at 4100N Zone (STOR1601D)
- Located on Somerset Island, 20 km north-west of the Storm Copper Prospect along the same structural trend.
- The Seal Zinc Prospect occurs predominantly as massive sphalerite and pyrite in the Ship Point Formation.
- Mineralization is hosted in an 8-to-10 metre (m) thick porous and permeable basal quartz-arenite with interbeds of dolostone and sandy dolostone.
- Zinc mineralization is present in two forms: coarse-grained, reddish-brown blackjack sphalerite and honey yellow, colloform sphalerite.
- Zinc mineralization occurs as local to complete replacement of the sandy dolostone interbeds as well as interstitial disseminations in massive sandstone beds.
- Nearby Storm copper mineralization produced an age of 378.1 ± 1.3 Ma*, within the range of uncertainty for the age of zinc mineralization at the nearby past- producing (20.1 Mt @ 13.4% Zn) Polaris mine at 374 ± 9 Ma**.
- Inferred mineral estimate (see below) demonstrates potential for high-grade zinc deposits. Recent Falcon AGG gravity survey provides incentive for further exploration.
