The FERROUX showing is located on the west side of Ferroux Creek approximately 9.5 kilometres north-northwest of Carmi.
The showing occurs in quartz monzonite of the Eocene Coryell Intrusions which is underlain by granodiorite of the Cretaceous- Tertiary Okanagan Batholith, overlain to the north by dacite of the Eocene Penticton Group, Marron Formation. A major fault is interpreted in the Ferroux Creek valley striking north-south.
Mineralization is associated with the Ferroux Creek fault where it is cut by east-west faults. Within and adjacent to these fault zones the quartz monzonite is brecciated, silicified and gossanous, with up to 10 per cent disseminated pyrite and minor pyrrhotite. Anomalous gold, silver, copper and zinc assays are associated with the fault structures.
The FERROUX showing was discovered in 1988 by Minnova Inc. through heavy mineral sampling techniques. Prospecting, geochemical and geological mapping programs were followed by trenching in 1989. A total of 355 metres was excavated in 9 trenches. Chip samples were collected from the trenches and analysed for gold, silver, copper, lead and zinc. The best precious metal values, obtained from trench 89-B, were 0.72 gram per tonne gold and 0.7 gram per tonne silver with lesser values of copper and zinc (Assessment Report 20070).
