Nickel – Copper – Manganese – Gold

Fraser Range

In November 2016, Sheffield and Independence Group (IGO) formed a joint venture to explore five of Sheffield’s tenements in the Fraser Range region.

The tenements occur within the Proterozoic Fraser Complex which is part of the Albany-Fraser Orogenic Belt, located on the southeast margin of the Archaean Yilgarn Craton. Red Bull is the most advanced project and is located within 20km of IGO’s Nova-Bollinger nickel-copper deposit.

Oak Dam & Leila

Historic exploration reviews have identified five significant nickel targets and four advanced gold targets on granted tenements E28/2481“Oak Dam” and E63/1696 “Leila”. These tenements are located around 50km to the north of the Nova/Bollinger Nickel-Copper deposit within the northern foreland region of the Tropicana Belt. The projects are prospective for both Tropicana style gold mineralisation and for nickel associated with ultramafic rocks that have intruded deep-seated structures separating the Yilgarn Craton from the Fraser Complex.

A substantial amount of historical, shallow, early stage exploration has been completed over the tenements, providing well defined nickel and gold targets for follow up work.

Limited reconnaissance rock chip sampling undertaken by Sheffield has confirmed elevated nickel values (up to 1.15% Ni) associated with ultramafic rocks. Further details of the nickel and gold targets are provided in Sheffield’s ASX release dated 3 July 2015.

Oakover Copper-Manganese Project 

The Oakover Copper-Manganese Project is Sheffield’s newest exploration project, targeting copper and manganese deposits in Archaean and Proterozoic-aged rocks of the Eastern Pilbara region of Western Australia. Sheffield has over 2,500 km2 of tenements under application, and two recently granted tenements covering about 570km2 within the Project and has begun detailed reviews of historical exploration data.
