The Lime North occurrence is located 10 kilometres west of the southwestern end of Eaglehead Lake, approximately 32 kilometres east-northeast of the community of Dease Lake.
Regionally, the area is underlain by limestone, marble and calcareous sedimentary rocks of the Mississippian to Triassic Kedahda Formation (Cache Creek Complex).
Locally, fine to coarse-grained marble occurs with a variable, but generally quite small component of argillaceous minerals. This marble is exposed as a very prominent steep-sided mountaintop and associated scree slopes, as well as numerous smaller outcrops in the lower elevations to the north, south and east.
In 2008, Hard Creek Nickel Corporation explored the area as a source of metallurgical limestone or marble for use as a mill additive at the proposed Turnagain Mill. A program of prospecting and rock geochemical sampling was completed. Analytical results, from eleven rocks samples collected, suggested that the majority of exposed carbonate at Lime North is of suitable purity for metallurgical use. Rock sample 08JK08-08 analysed 0.31 per cent MgO, 0.11 per cent SiO2 and 57.2 per cent CaO (Assessment Report 30760). However, the presence of 5 to 10 per cent silica, in four of the eleven samples recovered, suggests that silicate contamination of some portions of the carbonate body may be of concern (Assessment Report 30760).
