Development Update

Kapulo

The Kapulo copper project continues to advance in accordance with the revised schedule with most civil works now complete, key buildings erected and construction of steelwork underway. The Company's development review study, focused on design and cost optimization, is scheduled to be completed during Q2 2013 with commissioning targeted to commence late 2013. Further Mineral Resource definition drilling of the Shaba deposit and the Safari North and South deposits is being conducted in tandem with construction work.

Mawson West Chief Executive Officer and Managing Director Bruce McFadzean said: "Our strategy to establish Mawson West as a sustainable, low-cost copper producer from two operations remains on track, with production exceeding guidance during Q1 2013. The achievements to date are testament to the hard work of the operations team following the successful ramp-up of the Dikulushi open pit. Accordingly, Mawson West remains on track to meet published guidance of production of between 20,000 - 22,000 tonnes of copper in concentrate from Dikulushi for 2013.

"In addition, our 2013 exploration program to assess the potential of multiple near-mine and stand-alone opportunities is now well underway, with five rigs drilling numerous targets and Mineral Resource extensions within the tenements governed by the Dikulushi Mining Convention during 2013.

"The management of Mawson West remains committed to building on this excellent performance in order to deliver on the Company's strategy in 2013."

(1) The term "C1 cost" is a non-IFRS financial performance measure. C1 costs are direct cash operating costs per pound of copper in concentrate produced, net of silver by-product credits. Direct cash operating costs per pound include all mining and processing costs, mine site overheads and realisation costs (including transport costs, treatment and refining costs and smelter recovery deductions) through to refined metal.
