5,000 Tonne per Day Open Pit Mine Model

This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations.
All costs listed are in 2012 US$. The key design criteria, operating schedule, equipment, personnel, supply requirements and costs are listed below:

Available Cost Models

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order- of-magnitude estimates.

Surface mines: 36 Cost Models

production rates: 250 t/day to 80,000 t/day
stripping ratios 1:1 to 8:1

Underground mines: 48 Cost Models

production rates: 200 t/day to 45,000 t/day
access methods: adit or shaft
stoping methods: cut and fill, shrinkage, end slice, vertical crater retreat, sublevel longhole, room and pillar, sublevel caving, block caving

Placer operations: 32 Cost Models

production rates: 100 to 1,000 cubic yards per day
washing plants: mobile or stationary
stripping ratios: 1:1 to 8:1

Milling operations: 35 Cost Models

feed rates: 100 t/day to 80,000 t/day
flotation mills (1,2, or 3 concentrate products)
carbon-in-pulp mills
agitation leach mills

Gold heap leach operations: 6 Cost Models

leach rates: 5,000 to 20,000 t/day
run-of-mine or crush-screen-agglomerate operations

The models provide a great deal of important information about equipment, labor and supply requirements in addition to capital and operating costs. They include all labor, material, supply and equipment operation costs incurred at the mine site, including supervision, administration and on-site management. A more complete list of items included or excluded can be found in your Mining Cost Service Manual. The Manual also lists the wage and salary scales, supply prices, and other pertinent information used to construct the model.
