** 95% Mine Call Factor
Burnstone Mine continued to make good progress in a number of areas, notably in ore development which increased by 29% and in contained gold extracted (development and stoping), which increased by 16% compared to the similar period in the previous quarter. The lower square meters stoped follows the announcement that the stope configurations would be changed to improve operational efficiencies that will show in cash costs, dilution and recovery grades. More significantly, the number of square meters available for stoping increased by 45%. Tonnes milled decreased by some 14%, mainly due to the depletion of the low grade development ore stockpile in the previous quarter.
The Company has also closed the previously announced US$150 million credit facility provided by Credit Suisse Ag and Standard Chartered Bank and the funds were drawn down. The Company has executed the associated zero cost collars (ZCC) hedge structure, which replaces the previously remaining 91,250 US$1,705 call options as well as the unexecuted 40,000 call options under the standby facility announced in August 2011, totaling 131,250 ounces. The new structure includes 82,737 call options priced at US$1,890 as well as a further 82,737 call options priced at US$1,930. The delivery of these ounces is spread over the 5 years ending December 2016. The graph below indicates the Company’s total hedge exposure after executing the restructured ZCC. It includes the ZCC structure executed in February 2011 which also has a collar price of US$1,930. The news release with the graph included is posted on the Company’s website at:
Ferdi Dippenaar, CEO and President commented; “We are making good progress with increasing the rate of ore development required to increase the number of stopes available for mining at Burnstone. The decision to increase the size of the mining blocks was the correct one, with resultant operational efficiencies already starting to show. Current stoping continues to confirm that the decision to use Long Hole Stoping as preferred mining method was correct. In addition, concluding the debt facility provides the necessary flexibility to ensure that the delayed production build up can be funded.”
