Located 15 km south south west of Youanmi.
The prospect contains a 5 kilometres VMS trend. It is a large base metal target associated with volcanogenic massive sulphide mineralisation (VMS). It was discovered in the 1980's by BHP, or Western Mining Corporation 1971 to 1973 in another source.
There is an estimated 15 to 25 million tonnes at 2.5%Zn, hosting lode above 10% Zn. This does not appear to be JORC verified.
VMS base metal mineralisation is hosted with two shallow dipping sulphidic felsic volcanic units. The mineralisation is sheet like, 11 metres thick, and covering 1000 by 550 metres at what is called the North Dome prospect.
There are two styles of mineralisation (1) high grade massive sulphide with lenses of sphalerite several metres wide containing over 10%Zn, and associated with copper and (2) disseminated sulphides within a thick envelope of pyrite-pyrrhotite-sphalerite up to 20 metres thick, grading at 3-5% Zn. Silver is also noted here at 3-4 gpt.
