The AJM occurrence is located along Lost Creek, approximately 1.5 kilometres upstream from its mouth.

The only reference to this showing comes from Geological Survey of Canada Paper 41-5. It is described as quartz veins containing galena and pyrite with low gold and silver concentrations. No values are given. It is found less than 1 kilometre to the west of the Lost Creek Lead occurrence (MINFILE 093N 117) and may be the same one.

Where located, this occurrence is hosted by the Middle to Upper Triassic Slate Creek Formation argillites (Takla Group), which is within the right-lateral, northwest-striking Manson fault zone.

In 2008, Skygold Ventures Ltd conducted a drilling and soil geochemical survey on the Manson Creek property. Hole MC001 targeting gold soil anomalies within the Takla Formation was drilled approximately 200 metres northwest of the AJM occurrence. The hole intersected thick sequences of cataclastised phyllite-siltstone and graphitic phyllite with minor intervals of silicified and sericitised metasediments and intensely altered ultramafics with no significant assays.
