The Storm Copper Project is located approximately 20 kilometres from tidewater. The primary economic interest centres on four zones of significant copper mineralization — 2200N, 2750N, 3500N, and 4100N. Each zone was drill confirmed between 1997 and 2001; however, thousands of metres of historic drill core were never sampled. In addition, there are several target zones that have not yet been drill tested.
Storm Copper is a stratabound copper deposit hosted in dolomitic sediments of the Allen Bay Formation. Copper oxide mineralization is present at surface in the form of malachite, azurite and chalcocite. Malachite and azurite, along with primary hypogene chalcocite copper mineralization and the presence of bornite and chalcopyrite, have been identified to at least 100m of depth.
The property has been explored intermittently since the 1960’s; however, most of the historic work on the property was undertaken by Teck Resources Limited. Ninety-seven holes (14,171.3 meters) were drilled on the Storm and Seal zones between 1995 and 2001. Highlights from the historic drilling at Storm Copper 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
These two zones are characterized by outcropping copper mineralization and a strong electromagnetic response. Historic drill results for the 3500N and 4100N Zones are still being compiled and interpreted and will be released to the public when available.
In addition to the historical drill results, a 3,970 line-kilometre Versatile Time Domain Electromagnetic (VTEM) airborne survey was completed over the property in 2011. The results confirmed that the mineralized zones of the Storm deposit can be accurately mapped and modeled with electromagnetic techniques and the data suggests there remain portions of multiple zones that have not been adequately drill-tested along strike and beneath existing known mineralization.
An additional nine secondary anomalous targets areas were identified through inversion modeling of the VTEM data. These zones do not have characteristics similar to those of the main Storm zones, including the presence of visible copper mineralization, but they do represent areas of surficial or near-surface conductivity and merit further investigation. Aston Bay believes the Storm project holds significant potential, with a goal of testing an additional four to five new zones over the next year. Copper is becoming a rare metal, and high-grade copper with significant intersections is unusual.
