The Kelly occurrence is located approximately 15 kilometres southeast of Dortatelle Peak, 3 kilometres north of the Mesilinka River.

Mineralization occurs as disseminated molybdenite within pegmatites (Property File - Canadian Superior Exploration Limited, Maps from Company Files, c. 1973).

The occurrence is hosted in pegmatites cutting Early Cretaceous (or later?) granodiorites that intrude the Early Jurassic Hogem batholith. The batholith has recently been re-defined, from mapping to the south, to be part of the Mesozoic Hogem Plutonic Complex. Mapping in this area would probably indicate that the granodiorites are also part of the complex. Upper Triassic volcanics of the Takla Group lie just to the north of these intrusives.

The Takla Formation in the area consists of intermediate flows and tuffs, interbedded with minor amounts of calcareous fragmental and clastic sedimentary rocks. The Hogem batholith, in this area, is reported to be a coarse-grained granite. Within the contact areas, both volcanic and intrusive rock are cut by pegmatite and aplite dikes, and quartz veins.

No work has been reported on the Kelly since Canadian Superior Exploration indicated the showings on their maps circa 1973.
