The area of the Nicroco showing is underlain by Pennsylvanian tuffs, phyllites, siltstones and limestones and Lower Permian limestones, all of the Stikine Assemblage. These rocks are intruded by plutonic rocks associated with three separate igneous events consisting of foliated diorite of Triassic age, unfoliated diorite of Jurassic age and quartz monzonite and quartz feldspar porphyry, thought to be related to the Tertiary Sloko Group (Sloko-Hyder Plutonic Suite).

In 2015 Rio Minerals Ltd sent a 4-man crew to Fae property in order to conduct a short prospecting program. Two samples were collected on top of the ridge a few hundred metres northeast of the plotted location of the Fae occurrence and 5 samples were collected about one kilometre south of the Fae. A silicified light green outcrop sample (440503) located 1 kilometre south of Fae assayed 0.014 per cent nickel, 0.026 per cent chromium and 0.004 per cent cobalt (Assessment Report 35998).

See Fae (104K 014) for further details of the Fae property work history which begins in the early 1960s.
