The Nuthatch occurrence is located on the southwest side of a logging road in drainage ditches, near a creek, about 69 kilometres north-northwest of the community of Germansen Landing. The showing was discovered during the 1991 regional mapping program of the British Columbia Geological Survey.

At the showing, epidote alteration and malachite and azurite staining are found in massive, plagioclase phyric, maroon, amygdaloidal basalt flows of an unnamed unit of the Upper Triassic Takla Group. The flows are locally sheared and fractured and some carbonate veining is present. The mineralized zone is at least 15 metres across. A sample taken at this location assayed 0.13 per cent copper (Open File 1992-11, Sheet 2, Map Number 45).

In 1989, minor chalcopyrite mineralization along about one kilometre of new logging road was discovered by B. Bowen and A.C. Gordon.

In 1991, five claims (JB) were staked to cover areas of copper mineralization and favourable geology. Subsequent prospecting in 1991 by Bowen led to the discovery of additional chalcopyrite mineralization. Also in 1991, a mapping crew from the British Columbia Geological Survey visited the area’s road system and two new MINFILE showings were created based on their work (Fieldwork 1991). These are CR (094C 120) and Nuthatch (this description) which occur along the main road about 3 and 2 kilometres east, respectively, of the plotted location of the JB occurrence. The CR and Nuthatch were covered by the 1991 JB claims and the 2007 NewJB claims and prospecting by Bowen appears to have occurred in the plotted area of these showings.

In 2007, owner B. Bowen completed a 2.3-kilometre-long prospecting traverse along portions of a logging road system on the NewJB 1 and 5 claims. The objective of the work was to try to locate additional mineralized float and/or outcrop. In 2010, F. Shirvani conducted a lineament study and graphic depiction of structural features and an ASTER-based spectrometric study on the JB Project claims.
