INTERNAL Operating Performance Update S&C Draft of 5/26/10
2 INTERNAL Production Milestones June 26, 2012 First Nickel test briquettes were sintered. August 18, 2012 Single largest batch of slurry sent from the Mine (18,980 t), exceeding the Financial Completion target of 674 t/h. September 9, 2012 First Cobalt test briquettes were sintered. September 13, 2012 Operating permit granted. November 1, 2012 5 Autoclaves on line with dual slurry feed pumps November 8, 2012 First international shipment of refined nickel (40 t) November 13, 2012 First international shipment of refined cobalt (168 t) 2
3 INTERNAL Production Achievements to November 30, 2012 3 Mixed Sulphides to Refinery: Ni+Co contained, t6,900 Nickel Reduced, t5,512 Cobalt Reduced, t488 Amsul Produced, t10,695 Note: The Project achieved “Commencement of Commercial Production” as described in the Finance Documents on November 26, 2012.
INTERNAL PAL Overview Autoclaves PAL Autoclave Operating Hours Operated approximately 1,788 hours in November Ore Throughput in the PAL Autoclaves Processed 191,085 tonnes in November PAL Mixed Sulphide Production Produced approximately 1,763 tonnes of mixed sulphides (ni+co contained) in November 4
5 INTERNAL Refinery Overview 5 Sulphide Leaching In November we processed 1,694 tonnes of nickel and cobalt contained in mixed sulphides Nickel Reduction In November we reduced 1,592 tonnes of nickel powder Cobalt Reduction In November we reduced 164 tonnes of cobalt powder Metals Handling Produced 1,199 tonnes of nickel briquettes in November Produced 100 tonnes of cobalt briquettes in November
