The F.A.B. claims were staked in 1983 as a result of a discovery of tungsten skarn mineralization in float. The Otter Creek property is located west of Adams River, 10 kilometres southeast of Avola.

The property is underlain by gneiss, schist, pegmatites and interbedded limestone of the Shuswap Metamorphic Complex. Scheelite and autunite occur within pegmatite dikes.
