The Mitchell Range occurrence is situated 3.3 kilometres east-southeast of Klowkut Peak at the northern end of the Mitchell Range.

The occurrence is reportedly hosted within a pendant of ultramafic rocks in fault contact with Carboniferous to Jurassic sediments assigned to the Cache Creek Complex, near the north end of a large pluton of the Late Triassic-Early Jurassic Topley Intrusions. The ultramafic rocks consist of dark-black, variably serpentinized/silicified peridotite hosting pods and lenses of coarse-grained, altered pyroxenite (with tremolite-actinolite). Locally, rusty-weathering exposures of quartz-carbonate-talc±mariposite hosting anastomosing quartz and magnesite veins have been observed.

Detailed descriptions of the Mitchell Range occurrence are lacking. It is probable that it is similar to numerous other chromite occurrences that have been documented within ultramafic rocks underlying the Mitchell Range (Fieldwork 1982-1, pages 234-243). These occurrences comprise small, disseminated, aggregate (greater than 75 per cent) and massive chromite nodules and layers, which are predominantly hosted by allochthonous, serpentinized harzburgite, formerly assigned to the Middle Permian to Late Triassic Trembleur Intrusions and now termed Mississippian to Triassic Oceanic ultramafites. For regional geology details, please refer to the Simpson, Bob and Irish occurrences (MINFILE 093N 033, 34, 35).

A sample of malachite-stained, quartz-carbonate mineralization filling a shear zone approximately 750 metres north of the chromite occurrence's reported location assayed 0.345 gram per tonne gold (Assessment Report 16095, page 6).

Work History

In 1987, exploration was done on the property by Imperial Metals Corporation, including a program of geochemistry and mapping on its Cyprus claims. A total of 355 samples of the B horizon were collected along with 58 rock samples. Very few anomalies were found. One anomalous rock sample contained 0.345 gram per tonne gold (Assessment Report 16095). A maximum value of 0.295 gram per tonne gold was found in soil samples, and all anomalous values were coincident with nickel-chromite anomalies (Assessment Report 16095). Efforts to rediscover the chromite occurrence at this time proved unsuccessful.
