Expedition Mining has completed the 1073 line-km of airborne, high-resolution time-domain electromagnetic and magnetic surveys over the Mt. Mervyn and Joy properties.
Both the properties are located in the Rackla Gold Belt, which is a recently identified gold district that possess the Rau property of ATAC Resources including the Carlin-type gold mineralization.
The two properties comprising 717 line-km on the Mt. Mervyn and 356 line-km on the Joy were entirely covered at 100 m line spacing using the SkyTEM helicopter-borne system. The initial airborne survey results proposes that both the properties enclose major east-west trending structural zones that is situated parallel to and between the Dawson thrust and the Kathleen Lake fault. The traits of these structural zones are appearing to border the rock units containing mineralization at Osiris and Rau. Expedition has also found numerous north-south characteristics, which intercept the significant east-west structural zones. These are inferred to be faults that are analogous to those containing mineralization at the Osiris. Moreover, a magnetic signature connected to a mapped ultramafic unit at the Joy property outlines a huge east-west structural zone and provides the listwanite-hosted gold as a secondary target. These geophysical anomalies will be preceded with geological mapping and geochemical surveys in the 2011 summer exploration. The surface exploration programs are planning to upgrade any new discovery to the drilling phase.
