Residual iron oxide deposits are common in the Taseko River region of the southwestern Chilcotin where conditions are suitable for the development of these deposits, i.e. a source of iron (usually pyritic sediments and volcanics) and relatively stable depositional conditions.

The Battlement Creek bog iron showing, 1 kilometre north of Palisade Bluff, consists of nine separate patches of limonite that overlie Pleistocene till along both sides of Battlement Creek. The limonite ranges up to 1 metre in thickness. The iron was probably leached from altered pyritic tuffs of the Upper Cretaceous Powell Creek Formation which occur along the ridges to the south and southeast of the deposit; it was transported downhill in sulphate solutions and deposited as bog iron near the break in slope.

A minimum estimate of the reserve in 1920 was 12000 tonnes grading 49 per cent iron (Geological Survey of Canada Summary Report 1920A, pages 42 to 70A).
