The Leo Creek occurrence is situated at the extreme south end of the Mitchell Range, approximately 47 kilometres south-southeast of Takla Landing. It is one of numerous small chromite occurrences associated with ultramafic rocks located in the range (see 093N 033, 34, 35, 36, 37, 38, 39).

The occurrences comprise small disseminated, aggregate (greater than 75 per cent) and massive chromite nodules and layers which are hosted by allochthonous, serpentinized harzburgite, formerly assigned to the Middle Permian to Late Triassic Trembleur intrusions, and now termed Mississippian to Triassic Oceanic Ultramafites.

In the area of the occurrence, a large pluton of the Late Triassic-Early Jurassic Topley intrusions has been emplaced in Cache Creek Complex sediments. At the southern end of the pluton, a small mass of serpentinized ultramafic rocks reportedly hosts chromite mineralization. It is probable that this mineralization is similar to that in the Chrome Peak area to the north (see 093N 033, 34, 35, 36, 37, 38, 39).

No recent information concerning this occurrence is available and no economic evaluation is known to have taken place.
