Capsule Geology

The Mesilinka River occurrence is located about 12 kilometres east-southeast of Dortatelle Peak (Geological Survey of Canada, Memoir 251).

The occurrence is hosted in a Late Triassic Alaskan-type ultramafic body. The ultramafic body, intruding Upper Triassic Takla Group volcanics, is approximately 2.5 kilometres in length and trends northwest (Geological Survey of Canada Open File 342). The intrusion is obliquely truncated, to the south, by a northwest trending fault. Across the fault lies the Early Jurassic Hogem batholith.

Mineralization consists of disseminated chromite within pyroxenites and peridotites as grains and rare blebs. Several seams were noted at one locale ranging in width from 1.3 to 2.5 centimetres. The chromite grains/blebs were reported to be up to 1.3 centimetres in diameter (Geological Survey of Canada Memoir 251).

The Mesilinka chromite occurrence was discovered during Geological Survey of Canada mapping program prior to 1948, under the direction of C.S. Lord. Lord published the survey's findings as Memoir 251 in 1948.
