The Stikine River limestone occurrence outcrops along the Stikine River approximately 6.75 kilometres northwest of the confluence between the Stikine and Klappan rivers and 6.5 kilometres northeast of Tsaybahe Mountain, about 22 kilometres northeast of the the village of Iskut. The showing lies within the strongly dissected terrain of the Tanzilla Plateau.

Mapping of the area indicates that the limestone lens comprises part of the Lower Permian Stikine assemblage exposed along the southern flank of the Stikine arch. The limestone unit, measuring 1.8 kilometres by 800 metres, lies within a sequence of lower greenschist metamorphosed phyllites, phyllitic greenstones and ribbon cherts. The sequence, lying on the southwestern limb of the Tsenaglode Lake anticline, forms tight mesoscopic folds trending to the northwest. Units have been deformed by two phases of folding and two phases of regional metamorphism.
