This deposit is difficult to reach without local knowledge. A four wheel drive vechile is needed. It is located in forest deep in the Darling Ranges, approximately 29 kilometres south east of Mundaring Weir. The easiest access route is to take a track north of Brookton Highway, and after crossing the second creek (Darkin River), park the car just before the top of the hill immediately after the creek, then walk cross-country east for 200 metres. There are no access tracks to the deposit.
It was first and only noted in 1944, and dismissed as uneconomic.
The pegmatite is 120 metres long and 46 metres wide trending north-east. The deposit consists of six shallow diggings with much mica, and one three metre deep trench dug by a backhoe, exposing the smokey quartz core. Little visited and largely unexplored. It is likely to remain that way as it is located within a conservation reserve.
5 valid minerals.
