The Milkbone occurrence is located on the east side of Morris Creek at an elevation of approximately 1580 metres.
The area is primarily underlain by siltstone, argillite and quartzite of the Creston Formation, while dolomitic carbonate rocks of the Kitchener Formation, both of the Middle Proterozoic Purcell Supergroup, outcrop to the east and west. Gabbro sills and dikes intrude the sediments.
Locally, at the Milkbone zone, a 15-centimetre wide vein of massive galena is hosted by quartzite and/or phyllite in a minor shear zone, approximately 30 metres east of a gabbro sill. In 1997, a sample (MWGD97R-06) assayed 288.0 grams per tonne silver and 38.5 per cent lead (Assessment Report 25392). In 2013, a 0.5-metre chip sample assayed 39 grams per tonne silver and 4.81 per cent lead (Assessment Report 34632)
Another zone of mineralization, referred to as the Rundle zone, consists of shear-related chalcopyrite mineralization in metasedimentary rocks. In 2013, a 0.5- metre chip sample assayed 0.057 per cent copper and 0.047 per cent lead (Assessment Report 34632)
In 1986, Agincourt Explorations completed a program of rock sampling, geological mapping and underground surveys on the area. In 1996 and 1997, programs of rock, silt and soil sampling were completed on the area as the GD claims. In 2006, Eagle Plains Resources completed a 154.3 line-kilometre airborne geophysical survey on the area as the K9 property. In 2009, a further 479.1 line-kilometre airborne geophysical survey was completed. In 2013, a program of geological mapping and rock, silt and soil sampling was completed.
