Open pit and TSF mineral resources were generated by Mr Jonathan Kleynhans, an officer of the company and competent person. 2 TSF ore reserves are reported at a $1 000/oz cut-off grade of 0.5g/t. Ore reserves were calculated by Mr Shaun Gillespie, an officer of the company and competent person. 3 Attributable gold (Moz) refers to the quantity attributed to Randgold based in its 40% interest in Morila. Mineral resource and ore reserve numbers are reported as per JORC 2012 and as such reported to the second significant digit.
