Limestone outcrops in several locations on Bennett Range, 0.5 to 2.5 kilometres northwest of Bennett Lake.

The limestone occurs within the Boundary Ranges Metamorphic Suite, a Devonian to Middle Triassic succession of greenschist metamorphosed siltstones, wackes, basalts and pyroclastics. The sequence is contained within a northwest-trending belt up to 4 kilometres wide. The belt is intruded to the west by Late - and Middle Cretaceous granite and granodiorite of the Late Cretaceous Coast Plutonic Complex. A stock of the Late Triassic Stikine Plutonic Suite consisting of monzodioritic to gabbroic intrusive rocks intrudes to the immediate east of the occurrence. The strata have been warped into a gently plunging, tight to open syncline-anticline pair.

Exploration by Eagle Plains Resources in 2011 comprises an airborne EM and Magnetic geophysical survey on their Rohan property. The 204 line-kilometre survey was completed along idealized 100 metre spaced flight-lines, at a nominal terrain clearance of 30 to 40 metres. The 2011 airborne geophysical survey highlights numerous strong EM anomalies including at least two kilometre-scale ovoid anomalies, plus several linear anomalies associated with regional lithologic contacts.

In 2014, Rosedale Resources took 6 soil- and 2 rock samples along an east-flowing creek approximately 500 metres north to approximately 1 kilometre northeast of the Bennett Lake showing (104M 032). All samples yielded low values.
