Second Quarter Production Meets Guidance


PERTH, AUSTRALIA--(Marketwired - July 9, 2013) - Mawson West Limited (TSX:MWE) ("Mawson West" or "the Company") is pleased to provide an update on the copper and silver output from its Dikulushi mine in the Democratic Republic of Congo ("DRC"), where steady state production continued during the quarter.

Production of 5,189 tonnes of copper was achieved in the three months ended 30 June 2013, in line with guidance of 5,200 tonnes, as well as production of 475,397 ounces of silver.

Mawson West continued to improve the Company's cash position through Q2 2013, with cash on hand at 30 June 2013 totaling approximately US$39 million. In addition, ongoing revenue generated from operations allowed the Company to reduce its current debt obligations by US$7.5 million during the quarter, bringing total debt outstanding to US$22.5 million at 30 June 2013.

Underground Development

The Company has decided to commence extraction of the Dikulushi crown pillar through underground mining methods. Mining of the crown pillar is scheduled to commence in Q3 2013 and is expected to extend processing into Q2 2014. Due to the existing underground infrastructure, expenditure requirements to mine the crown pillar are minimal, estimated at US$3.1 million for capital and US$2.2 million for pre-production operating costs.

Mawson West is conducting an underground mine study to examine the feasibility of longer term underground mining operations at Dikulushi. Previous mine owner, Anvil Mining Limited, abandoned underground operations during the 2008 Global Financial Crisis. The results of this study are scheduled to be released during Q3 2013.

Concentrate Exports

Mawson West continues to export concentrates in accordance with the terms of the Dikulushi Mining Convention. As previously stated (see press release dated April 18, 2013), the Company has not experienced, nor does it anticipate, any delays in relation to the export of its concentrates.

Mawson West Chief Executive Officer and Managing Director Bruce McFadzean said: "Our open pit operations at Dikulushi continued to perform well during the quarter, ensuring the Company was able to meet its published guidance."

"In addition, the underground mining potential at Dikulushi presents Mawson West with an opportunity to increase its production profile and generate additional cash flow. We look forward to delivering the outcome of the studies underway at Dikulushi in the coming months."
