The Jack White West (Icky) occurrence is located at an elevation of approximately 1400 metres on a steep south facing slope, north of Ainslie Creek and approximately 8.5 kilometres north east of the creeks’ junction with the Fraser River.
The Stoyoma (Eke-Waki) Mountain area is underlain by granodioritic intrusive rocks of the Permian to Triassic Mount Lytton Complex and Permian to Early Jurassic dioritic intrusive rocks which host local pendants of Paleozoic to Mesozoic limestone, marble and calcareous sedimentary rocks.
Locally, a lens of massive magnetite-sulfide with variable amounts of garnet, diopside and epidote has been identified in outcrop. Sulphides include 10 to 15 per cent pyrite with minor chalcopyrite. The lens dips 60 degrees to the southwest and is exposed over a width of approximately 3 metres and length of 35 metres.
In 2017, three outcrop rock samples (CP-JAW-22 to -024) yielded values from 33.8 to 36.1 per cent iron and 0.085 to 0.273 per cent copper (Price, B.J. (2017-10-16): Technical Report - Jack White Property).
In 2018, a float sample (JW18-OF-006R) of massive magnetite with disseminated to blebby chalcopyrite and pyrite assayed 31.07 per cent iron and 0.085 per cent copper (Assessment Report 38147).
Another zone of semi-massive to massive magnetite with pyrite, chalcopyrite and pyrrhotite mineralization, referred to as the Western (Fe) Iron and/or Lightning zone, is reported near a peak located approximately 1.5 kilometres to the north of the occurrence. Samples from this zone are reported to have yielded up to 24 grams per tonne silver and 1.44 per cent copper (White, 1958-1960 - Property File).
In 2018, samples (JW08-OF-011R and -010R) from the Lightning zone yielded 41 and 44 per cent iron, respectively, whereas samples (JW08-OF-019R and -017R) with abundant garnet and semi-massive to massive pyrite, chalcopyrite and pyrrhotite mineralization, taken from the edge of a magnetic high in the Lightning zone, yielded 0.264 and 0.239 per cent copper, respectively (Assessment Report 38147). Also at this time, a sample (JW18-CS-015R) of a fine-grained gabbro (dyke?) with semi-massive magnetite and pyrite assayed 0.465 per cent zinc (Assessment Report 38147).
