Blue Sky Project - Edmonton
MLM has two more greenfield projects, Edmonton and Cascade that are in the vicinity of the intersection of the Mayo Lake antiform and Robert Service Thrust. Complex structural geology and a history of mafic and felsic intrusions make these fertile areas for mineralization.
Edmonton is composed of 95 claims covering an area of 19.5 square kilometres near the eastern arm of Mayo Lake. The claim group is also accessible by helicopter from Mayo Lake. It is bordered to the west by Edmonton Creek, a historically active placer creek. Other creeks to the east were also placer mined in the past.
The surface cover at Edmonton is a mixture of colluvium and till. The youngest glaciation affecting Edmonton was confined to the valley occupied by Mayo Lake. This valley was filled with westward fast-flowing ice that scoured its bottoms and sides. The highest part of uplands was probably covered by older cold-based glacial ice during an older glaciation, transport of rock and debris being minimal.
Edmonton is underlain by the Robert Service Thrust (RST), which is a broad structure containing a complex intermingling of Keno Hill Quartzites and Hyland Group metasediments intruded by competent gabbroic rocks. Local prominences on the plateau that Edmonton covers correspond to gabbro stocks. The thrust limit of the RST is mapped as a surface trace on Edmonton, when it is more likely a series of multiple sub-horizontal faults.
Airborne magnetics was flown over the property in 2012. It delineated a large geophysical anomaly in the southern part of the claim group with one boundary that is marked by elevated gold in soil values (Figures 2 and 6). This anomaly is interpreted to be a buried stock or alteration zone of unknown provenance. The true extent and nature of gold in rock source has yet to be determined. Other magnetic lineations clearly showed faults and fractures that controlled mineralization, including one Au anomaly that trends to the northeast from the probable alteration zone a distance of over 1000m.
