Aston Bay Holdings (BAY-V) digs up old Storm results of 110m of 2.45% Cu
Sept 3rd 2013 - News Release
Aston Bay Holdings Ltd. has provided a summary of historic drill results and technical data at the 2200N and 2750N zones from the company's Storm copper project.Highlights from the historic drilling include 49 metres of core length grading 1.79 per cent copper (Cu) from surface at the 2200N zone as well as 110 m core length grading 2.45 per cent Cu from surface and 56 m core length grading 3.07 per cent Cu from 12.2 m at the 2750N zone. The two zones are separated by 500 m and are characterized by outcropping copper mineralization and a strong electromagnetic (EM) response.
"These drill results clearly demonstrate the exceptional potential of the Storm copper project," said Bruce Counts, chief operating officer of Aston Bay Holdings. "The property has a solid foundation of historic data from which the Aston Bay team can build and we are eager to continue advancing the project."
The associated table lists a summary of grades from holes drilled at Storm's 2200N and 2750N zones.

In 2011, a 3,970-kilometre helicopter-borne versatile time-domain electromagnetic (VTEM) survey was completed over the Storm property. Strong conductivity responses were identified coincident with the 2200N and 2750N zones and results suggest that mineralization in both zones may extend laterally and to depth beyond the current drilling envelope.
"There is ample evidence to suggest that the dimensions of the mineralization at the 2200N and 2750N zones is significantly larger than has been defined by the historic drilling," said Mr. Counts. "The results of the VTEM survey, coupled with the geologic model developed from drill core, indicate that mineralization may extend well below the deepest hole."
The 2200N zone is exposed along the Aston River ridge proximal to the 2200N fault. The zone is defined by a 600 m zone of surface malachite and azurite in frost boils and bedrock chips, with subsurface continuity of mineralization interpreted from historic induced polarization/resistivity (IP) and horizontal loop electromagnetic (HLEM) surveys. A series of seven widely spaced diamond drill holes completed during 1997 and 1999 define a 550 m long, 200 m wide mineralized zone consisting of poddy to net-textured chalcocite and bornite occurring as breccia cement, fracture fill and veins to a depth of 100 m. Semi-massive sulphide zones are separated by wider zones of vein and stringer mineralization. Fine-grained, disseminated native copper occurs in near-vertical, net-textured veinlets and stringers proximal to the 2200N fault. Preliminary geologic modelling of the 2200N zone indicates the presence of four shallowly dipping stacked strata-bound mineralized horizons and a vertical feeder zone.
At surface, the 2750N zone is marked by a 100 m long, east-west-trending malachite-stained gossan adjacent to the 2750N fault. A total of 13 diamond drill holes completed between 1996 and 1999 testing surface mineralization and IP anomalies intersected copper mineralization over a 270 m strike length from surface to a minimum depth of 80 m, the zone narrows from 50 m at surface to 25 m at depth, and occurs in an area of complex faulting. The 2750N zone appears to be structurally controlled with a strong vertical component to the mineralized body. A progressive zonation of copper minerals both vertically and laterally away from the 2750N fault has been identified from the historic drilling, with a near-surface chalcocite-bornite zone giving way to a chalcopyrite zone at depth.
Next steps
Over the coming months, historic data will be integrated with the information collected during the 2013 field program to provide a more concise understanding of the mineralization at the Storm copper and Seal zinc prospects. Select information will be released to the market as the data are interpreted and the company grows its knowledge of the copper- and zinc-mineralized zones on the Storm property.
