The main orebody of the Bodangora mine is a metalliferous quartz reef within a major fault plane in the strongly folded and faulted volcanic rocks of the Ordovician-Silurian Oakdale Formation. The similarity of the type of mineralization to that of other pyrometasomatic deposits in this area suggests that the mineralizing fluids originated in the nearby Wuuluman Granite.The associated Mitchell's Creek West or Dick's reef is discussed briefly.
