This showing is 2.4 kilometres southeast of the confluence of Finnegan and Hayes creeks and 19 kilometres northeast of Princeton.

The FK occurrence is hosted in strongly fractured and altered granite of the Middle Jurassic Bromley batholith, possibly within the same northerly striking fault zone that hosts the Hematite occurrence (092HNE026), 1.8 kilometres to the north.

The dump of an old pit contains fragments of coarse-grained porphyritic granite with strong argillic alteration. Malachite occurs along fractures in most of the fragments. Minor specular hematite is disseminated through the granite.
