Once the slot is mined by the end of Q1 2016 and all trough tunnels completed during Q2 2016, longhole ring blasting for production troughs will commence. UK4 production from January 2016 to the end of March 2016 is scheduled to average 4,000 tonnes per month: April to June 2016, an average of 15,000 tonnes per month, then full production of 30,000 tonnes per month from July 2016 onwards. DiamondCorp Chief Executive Officer, Paul Loudon, said: “Today is an historic day for the Lace mine as it marks the start of the ramp up towards commercial production from underground at Lace for the first time since October 1930. Production to date has come from access development and tailings retreatment; from now on production will be dominated by mining development, stoping and block caving.” Contact details: DiamondCorp plc Paul Loudon, Chief Executive Tel: +27 56 216 1300 Euan Worthington, Chairman Tel: +44 7753 862 097 UK Broker & Nomad Panmure Gordon (UK) Limited Dominic Morley/Adam James Tel: +44 20 7886 2500 JSE Designated Advisor Sasfin Capital (a division of Sasfin Bank Limited) Megan Young Tel: +27 11 445 8068 SA Corporate Advisor Qinisele Resources Proprietary Limited Dennis Tucker/Andrew Brady Tel: +27 11 883 6358 Johannesburg 17 December 2015 Date: 17/12/2015 07:22:00 Produced by the JSE SENS Department.
