Mineralization is a N.30ºW.-striking oxide facies banded iron formation. A 60 to 90 cm thick sequence of laminated hematitic, but highly magnetic iron formation strikes approximately N.30W. and dips about 50ºSW. The zone can be traced for more than 200 meters along the strike. This iron formation is very closely associated with laminated, fine-grained amphibolite.

Workings include an approximate 20 meter deep, verticle shaft.
