The Fitzgerald showing is located adjacent to Highway 37A, on the north side of Strohn Creek, approximately 9 kilometres east of Strohn Lake.

In 1917, three claims were located over the showing by the Fitzgerald brothers. Recent work, from 2005 to 2007, included geochemical sampling of outcrop, soil and silt.

The area is underlain by the porphyritic Tertiary(?) Strohn Creek pluton (Bulletin 63), which intrudes Hazelton Group sediments of the Middle Jurassic Salmon River Formation. The Strohn Creek pluton is a massive, coarse grained quartz monzonite that contains large phenocrysts of potash feldspar, minor biotite, lesser hornblende and accessory apatite, zircon and magnetite. Mineralization in the pluton consists of molybdenite, typically associated with quartz, along joint surfaces and fractures (Bulletin 63, page 80).

The Fitzgerald showing consists of a 1 to 2 metre wide quartz vein, in the quartz monzonite, that contains molybdenite (Minister of Mines Annual Report 1917, page 68). A sample, weighing several hundred kilograms, was reported to average about 6 per cent molybdenite (Minister of Mines Annual Report 1917, page 68).

In 2005, select outcrop samples of mineralized dike material yielded 0.18 to 0.23 per cent molybdenum. In 2007, sampling returned up to 0.045 per cent molybdenum (Assessment Report 29917).
