Jan 26, 2016 (A Wilson) - The occurrence is described as a series of 10 narrow parallel bands of iron formation. The iron formation is described as cherty and contains jasper and specular hematite. The crystal tuffs show widespread and localized areas of pervasive diatreme-like chlorite alteration. The felsic rocks are cut by a number of sulphide-rich fractures.
