摘要

Production scheduled to start in 201 5. * GBC block cave mine: under development and scheduled for production in 2016. * Kucing Liar (KL): future cave adjacent to the GBC The DMLZ block cave reserve totals SOl Mt (552 million st) at 0.89 percent copper, 0.74 g/t (0.022 oz/ st) gold and 4,4 g/t (0.13 oz/st) silver. Prefeasibility level designs for the MLZ and DMLZ were advanced during 2004-2005. Since lhese origina studies were issued, further exploration core drilling, updated resource calculations and redefined metal pricing resulted in revisions to lhe orebody block model and the projected minable footprint.
