AMIS0213 Au 1.38g/t, Greenstone, North Mara, Tanzania
Origin of Material: AMIS0213 is a commissioned CRM made from material supplied by SGS Minerals Services from the North Mara Gold Mine, which is wholly owned and operated by African Barrick Gold plc.
The North Mara Gold Mine is located in the northwestern part of Tanzania, 200km northeast of Mwanza, in Tarime District of Mara Region. This is 100 kilometres East of Lake Victoria and 20 kilometres south of the Kenyan border. The North Mara mine consists of three open pit deposits. Mining is under way at Nyabirama and the Nyabigena pit is in the development phase. The Gokona pit is currently being prepared for development.
The project comprises an Archaean granite-greenstone terrain, partially covered by Proterozoic sediments and Tertiary volcanic. The Mara greenstone belt hosts widespread, dominantly shear-controlled, gold mineralisation.
Mineral and Chemical Composition: The main body of the mineralisation is hosted within a zone of intense silica-feldspar-sulphide flooding that lies strike-parallel to and up dip of the Mara Shear.
