• Oblate search ellipsoids, long on strike

• 10m x 10m sampling grid

Reef model detailing-On Cross Section

8

• Oblate search ellipsoids, longest along dip

• Different mining regimes

PLATINUM

The Miner’s Mine• Large equipment, bulk mining• Low cost, economies of scale• Good for waste striping and a few ore areas

PLATINUM

The Metallurgist’s Mine

10

• Homogeneity of ore feed• Poly-metallic content• Alteration of gangue minerals• Variation of ore minerals

• Feed material in campaigns/batches with notifications in advance

• Inherent variation is in ore, many parameters not additive, blending complicated

Mogalakwena- the way forward• A well understood geological resource- can never

drill enough!• A well planned reserve and a continually improving

execution plan• A well skilled/disciplined miner, more and smarter• A dynamic stockpiling strategy• An adjustable campaign fed processing multi-

parametric strategy , geo-met optimised• Intelligent mining and process monitoringsystems
