The Latremouille copper occurrence is located on Highway 24, approximately 500 metres northeast of Latremouille Lake, 17 (air) kilometres northwest of Little Fort.
Fieldwork 2000 (pages 21 and 25) describes an outcrop of epidote-altered hornblende diorite along the northeast margin of the Triassic to Jurassic Thuya batholith cut by a narrow, mineralized quartz vein that dips gently to the west. A sample of mineralized vein material (00SIS-17), which contains pyrite and traces of chalcopyrite, yielded 2.2 ppm silver and 892 ppb gold.
This showing is one of several disseminated copper occurrences which occur within and along the margins of the Thuya batholith which is composed mainly of granodiorite, diorite and monzodiorite. On its east side, the Thuya batholith contacts diorites and gabbros of the Triassic-Jurassic Dum Lake Intrusive Complex.
No work is known to have been completed on the occurrence.
