The occurrence is located approximately 30 kilometres west of Castlegar, 4 kilometres north of Highway 3 or 7 kilometres northwest of Nancy Greene Provincial Park.

Regionally, the area is underlain by porphyritic granite, granodiorite, quartz monzonite, monzonite, and tonalite making the Middle Jurassic Nelson intrusions. These are intruded by coarse-grained porphyritic syenite, lesser granite, diorite, and monzonite, named Middle Eocene Coryell batholith and tertiary mafic dikes (MINFILE 082ESE275 – JJ).

Locally, Borrow Pit is a roadside cut with a north trending limonite stained quartz vein about 0.5 metres wide containing gold and copper mineralization. Float and outcrop samples showed quartz stockwork veining with minor sulphide and arsenopyrite mineralization. In general, similar mineralization to the JJ Main occurrence MINFILE 082ESE275.

In 2003, grab samples from Kootenay Gold Corp. found gold grades between 0.007 and 8.94 grams per tonne (Brittliffe, D., Terry, D. (2007-02-28): 43-101 Report on Exploration at the Jumping Josephine Property, Southeastern British Columbia).

In 2006, a soil sampling program by Astral Mining Corporation found arsenic values ranging from 0.00011 to 0.00367 percent defining a broad anomaly on the Big Sheep occurrence (Turner, A. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property).

In 2007, a trenching program by Astral Mining Corporation found up to 8.9 grams per tonne gold from four trenches and 96 samples (Turner, A. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property). The shear zone observed in the trenches was north-south oriented, like a past elongated magnetic low in the area that could lead to discovery of more mineralization.
