Some Design Criteria
n Two shaft systems – approx. 3,2km’s apart- One material and one conveyor shaft- Chairlift decline added later- Hillside adit mining
n 200 000 ton per month concentrator- Natural fines circuit - Autogenous / ROM ball milling- Chrome silica circuit
n Central infrastructure - Offices and training facility
Some Design Criteria
n Conventional stoping- Raises - Down dip stoping- Handheld drills
n High productivity mine:- Continuous operations- Two panel cycle- No night shift on the reef plane- Concentrator has high level of process control

Mine Design Optimisation
n Structural features including slumps, potholes, shear zones/faults, undulating reef, and pegmatite replacement bodies although challenging are being successfully addressed
n An increased drilling density is enabling optimal positioning of drives and access ramps.
n Dip drives are in place to fit optimal raise backs
n The base of the regolith / UG2 interference line is determined ahead of mining
Mine Design Optimisation
n Groundwater modeling and management is in place. Surface appears dry – small secondary aquifers do exist - dewatering programme in place
n Geological logging and modelling is in place and assists in optimal cut selection
Exploration Drilling Programme
Planned drilling for 2003 :
n Surface drilling 24 600 mn Underground drilling 14 600 m
n Total 39 200 m
n Density matched to achieve optimal mine design
