The Kid copper occurrence is situated on the boundary between the Kid 3 and 4 claims, on a small creek immediately west of Racing River, 13.5 kilometres due east of Yedhe Mountain in the Muskwa Ranges in the Northern Rocky Mountains (Assessment Report 1042, Figure 2).
The occurrence is in an area of folding and complicated thrust faulting, immediately west of the Sentinel thrust, in a major north-northwest–trending structural region known as the Muskwa Anticlinorium. The Kid group of claims is underlain by rocks ranging from the Middle Proterozoic Tuchodi Formation, part of the Helikian Muskwa Assemblage, and unconformably overlying Silurian and Devonian sedimentary rock units (Geological Survey of Canada Memoir 373, Map 1343A; Geological Society of America, Geology of North America, Volume G-2, pages 111, 639). All belong to Ancestral North America (Geological Survey of Canada Map 1713A).
In more detail, the area around the mineralization is cut by a fault that offsets the contact between Lower to Middle Devonian dolostone, sandstone and shale, and older Paleozoic, either Cambrian or Silurian, quartzite (Assessment Report 1042). The stratigraphic units present probably include the Upper Silurian to Middle Devonian Muncho-McConnell, Wokkpash and Stone formations, and the Lower Silurian Nonda Formation. The Tuchodi Formation may also outcrop in the vicinity. Bedding strikes northwest and dips gently southwest, approximately 5 degrees, although tightly folded limestone and sandstone are present adjacent to the fault. A diabase dike, striking north-northeast and dipping 15 degrees northwest, intrudes the Devonian rocks.
There is much shearing and alteration in the immediate area, presumably related to the faulting. A large gossan occurs around the dike and is well exposed in the creek valley. Mineralization consists of massive pyrite and disseminated chalcopyrite and bornite. The mineralization has a strike length of approximately 120 metres (National Mineral Inventory). An electromagnetic anomaly was located here (Assessment Report 1042).
In 1966, a float sample of massive chalcocite-bornite assayed 57.47 per cent copper (Assessment Report 1042).
Work History
In 1966, Racing River Mines Ltd. completed a program of geological mapping and a ground electromagnetic survey on the area as the Billy, Kid, Nanny and Sam claims.
In 2005, Twenty-Seven Capital Corp. completed a regionally extensive program of geochemical (rock, silt and soil) sampling and a 9002.0 line-kilometre airborne magnetic survey on the area as the Muskwa property (Assessment Report 28281).
