Located 10 km west of Zeehan. Owned by Allegiance Mining N.L.

A group of nickel sulphide rich, skarn-like deposits. The host rocks are a series of Cambrian sediments, mafic volcanics and ultramafic flows or intrusives. Nickel mineralisation in the host rock sequence was remobilised by the Devonian Heemskirk Granite intrusion, then focused and redeposited in trap sites around the top and margins of the altered ultramafic body (http://www.allegiance-mining.com.au/default.asp?id=29 [Link Broken? May 2013]).
3 Mt reserves at 1.54 % Ni. Full production is expected to commence in February 2008.

An unique example of a significant Ni sulfide deposit associated with an ophiolite sequence.

Note: Valleriite-Haapalaite series - actual species not yet confirmed.
