The Rum 2 occurrence consists of a small showing of copper and molybdenum mineralization on a narrow ridge north of Nine Mile Creek, between the toes of Hamilton Glacier and Austen Glacier, 25 kilometres southeast of the southern end of Tatlayoko Lake.

The area of the occurrence is underlain by greywacke, shale and siltstone of the Lower Cretaceous to Upper Cretaceous Taylor Creek Group. Bedding strikes northwest and dips moderately southwest (Assessment Report 2671). The area is part of a Cretaceous overlap assemblage. The Rum 2 showing occurs just west of a thrust fault that thrusts a panel of the Taylor Creek rocks east onto another panel of Taylor Creek rock. Information on the mineralization is very limited. Pyrite, chalcopyrite and molybdenite are present in a northeast-trending gossanous zone. One rock sample assayed 3.4 grams per tonne silver (Figure 2, Assessment Report 2671).

Geological mapping in 1970 by Pacific Petroleums Ltd. on their Rum 1-96 mineral claims has shown that a number of small, mineralized zones occur sporadically throughout an area 1525 metres long and 215 metres wide within a Cretaceous to Paleocene stock of the Bendor suite. Mapping was done with much less detail on the Ram claims farther afield from the stock. Though the Bendor suite stock occurs about 3 kilometres northeast of the Rum 2 showing, a large plutonic mass of the Bendor suite occurs a few kilometres to the west and was/is considered to be part of the eastern edge of the Coast Plutonic Complex.
