Mining Equipment - Capital and Operating Costs. Productivity.

Hi,



How do people get costs for mining equipment? Diggers, trucks and ancillary equipment.



Things I am looking for are:



Repair & Maintenance Costs (Basic)

Repair & Maintenance Costs (Unscheduled/Accidental)

Grease/Oil consumptions

Tray Life

Tray Cost

Tray Overhaul Cost

Tyre Life/Replacement Cost

Capital Costs

Mobilisation/Demobilisation Costs

G.E.T



etc etc...



I imagine many keep this data keep this close to their chest but are there paid services which compile this data?



I am also looking for productivity data of various equipment - particularly diggers.
