At $3,500 gold, Kinross estimates a $3.2-billion net present value, 22% return and 2.7-year payback. Mine planLobo-Marte contains proven and probable reserves of 160.7 million tonnes grading 1.3 grams gold per tonne for 6.73 million contained ounces. Indicated resources stand at 120.8 million tonnes at 0.71 gram per tonne for 2.75 million oz., while inferred resources total 32.9 million tonnes at 0.63 gram for 670,000 ounces. The operation would process 161 million tonnes of ore through a three-stage crushing and heap-leach plant rated at 35,000 tonnes per day. Growth scopeThe initial plan would recover 4.6 million oz., leaving much of the project’s resource outside the reserve pits.
