The Jump occurrence is located about 9.6 kilometres northwest of Aiken Lake and approximately 108 kilometres northwest of the community of Germansen Landing.
The Jump showing consists of minor occurrences of malachite and possibly chalcopyrite hosted in a flow of augite/feldspar porphyry agglomerate of the Upper Triassic Plughat Mountain Formation (Takla Group). The mineralization appears to be related to a mafic-rich marginal phase of a hornblende porphyry dike which cuts the Takla rock. There is some local shearing but its association with the mineralization is unclear.
In 1992, a grab sample of the mineralization taken for analysis yielded 0.48 per cent copper, 0.015 gram per tonne gold, 0.021 per cent zinc and 0.013 per cent lead (Open File 1993-2, Map Number 32).
