During Q4 2013 Mawson West completed processing stockpiled material from the Dikulushi open-pit and campaign processing of low grade material has continued into 2014. Underground mining operations have commenced at Dikulushi. Underground mining is expected to extend production from the Dikulushi operations until at least Q3 2014 and provides the opportunity for Mawson West to evaluate additional underground mining potential as well as the economic viability of identified satellite deposits.

Financial

Mawson West’s copper and silver sales totalled US$37.51 million for Q4 2013 with an average copper price received of US$3.21 per pound (US$7,075 per tonne) and an average silver price received of US$20.13 per ounce.

The Company’s cash position as at 31 December 2013 totalled approximately US$48 million1 and follows initial Dikulushi underground capital investment and continued debt servicing obligations. Total debt outstanding as at 31 December 2013 was US$7.5 million.

Mawson West Chief Executive Officer and Managing Director Bruce McFadzean said:

“2013 has been a transformational year for Mawson West which has seen the Company deliver against our stated production targets despite broader challenges within the resources sector. In 2013 we have been able to reduce our debt by almost US$28 million and we commence 2014 with a sound balance sheet providing a solid platform to pursue production growth from our existing assets at Dikulushi and Kapulo.”
