The D8 occurrence is located in an east- to southeast-trending valley, west of the Racing River and approximately 10.5 kilometres southwest of the junction of Delano Creek and the Racing River.

The occurrence is in a region known as the Muskwa Anticlinorium, a major north-northwest–trending structure characterized by moderate folding and thrust faulting. The structure consists of Middle Proterozoic (Helikian) rocks of the Muskwa Assemblage, as well as Paleozoic rocks (Geological Survey of Canada 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). Northeast- to northwest-trending Proterozoic diabase dikes of Proterozoic are common in the region.

The area is underlain by the Aida and Tuchodi formations of the Muskwa Assemblage, and by rocks of the Cambrian Atan Group (Geological Survey of Canada Memoir 373). The mineralization appears to be confined to Aida Formation rocks, which in this area consist of limy and dolomitic slaty argillite and siltstone, sandstone, dolostone and limestone. Bedding strikes northwest and dips moderately southwest.

Locally, quartz-carbonate veins cutting dolomites are weakly mineralized with patchy chalcopyrite and malachite.

Work History

In 1979 and 1980, Halferdahl & Associates Ltd. completed a regional program of soil sampling on the area as the Tuchodi property.

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. An outcrop(?) sample (B374218) assayed 0.33 per cent copper, whereas a nearby float sample (B374217) yielded 3.95 per cent copper (Assessment Report 28281).
