Mayo Lake Claims Groups, Yukon Territory


Cascade is composed of 52 contiguous quartz claims covering an area of 10.5 square kilometres near Mayo Lake. It covers a moderately sloping prominence overlooking a former producing placer creek draining into the Nelson Arm of Mayo Lake. The claim group is also accessible by helicopter and from Mayo Lake, which has a boat launch at its west end.

Cascade has been subjected to multiple glaciations. The ice was probably cold-based due to the elevation of the upland, and transport of rossssck and debris was minimal. The surface cover is a mixture of colluvium and till.

The property is underlain by the Robert Service Thrust (RST), which is sub-horizontal, and underlies much of the property. It includes a complex intermingling of Hyland Group Metasediments intruded by competent gabbroic rocks and amphibolite dykes. Geophysics flown in 2012 by MLM suggests that the surface trace of the RST is folded around the nose of the Mayo Lake Antiform on or adjacent to the property (Figure 15). This structurally complex zone has good potential to host mineralized structures.

Definition sampling has delineated five gold in soil anomalies (Figure 7); one sample yielded 2.25 g Au/t. The anomalies are all open in at least one direction. Two gold anomalies have associated pathfinder anomalies suggesting a felsic intrusive or skarn-type provenance. The other gold anomalies have element associations suggesting intrusion related or orogenic-type provenances for the gold; two of them have strong As and Sb associations.

More detailed soil sampling is warranted to define potential gold mineralization in areas where reconnaissance soil sampling and airborne magnetics indicate good potential for gold mineralization.
