Aug 26, 2011 (A Wilson) - The pyrite forms a conformable body contained within mudstone in a sequence of mudstone and sandstone. The sandstones have been intruded by a small body of granitic rock just to the west of the pyrite deposit. All units strike northwesterly and dip shallowly to moderately to the northeast.

Aug 26, 2011 (A Wilson) - The mineralization consists of a massive intergrowth of pyrite and quartz that is often gradational into the mudstones such that the mudstones sometimes contain abundant disseminated pyrite. Within the massive ore, the pyrite usually forms medium to coarse-grained (1-10 mm) subhedral to euhedral crystals disseminated within a rock composed of aphanitic greyish-white quartz.
