Located 94 kilometres north-west of Fitzroy Crossing. Three pits were dug into an olivine lamproite sill, recovering 25 diamonds totalling 2.23 ct.
Described as a hill of the Grant Group sandstone. Lamproite tuffs and intrusives occupy a small area at the base of the hill. Brecciated sandstone surrounds the former vent, with sheets arranged concentrically around the vent.
Mindat map approximate. The prospect is assumed to be near what Google Maps names as the North Percy Airstrip, being the only airstrip in the area. The location is different to the neighbouring Ellendale 4 Mine.
