This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.
In this paper, in order to achieve a reliable cost model, the technical and economic data of 15 open pit porphyry copper mines have been collected. The proposed cost model is developed based on
Background information, formulae and a systematic set of procedures for estimating capital and operating costs for open pit mining equipment are presented in this paper. Firstly, equipment capital costs are required. These can be obtained from either suppliers, contractors or from first principles. The equipment is then divided into cost elements.
Mining Cost Model. 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. The total resource to be mined is 18,715,000 tonnes. Ore is hauled 1,068 meters to an ore stockpile. Waste is hauled 535 meters to
Open Pit Mine Design, Planning, and Engineering Mine cost estimation may be done at many levels. At first it may be a simple “back of the envelope” estimation using similar operations to benchmark against. Later it may be decided to use an existing mine that the company owns and factor and compare costs against them.
It is assumed that the cost of mining ore is the same as that of mining waste. The cost of mining comprises drilling, blasting, Ioading and hauling, (in addition the cost of crushing). The cost of open pit mining can be assessed using the total ore and waste (T) mined daily (Table 1).
Mining capital cost estimation using Support Vector In this paper, data of 52 open pit porphyry copper mines have been collected. This study tries to benefit from Support Vector Regression theory to develop a cost estimation model.

Mining Cost Service is the industry standard reference for Mining Cost Estimation. This system places cost estimating data at your fingertips with conveniently indexed information to make your cost estimates faster, easier, and more credible. Monthly updates assure that you are working with the most current cost data available.
concentration, and heap-leaching of copper using commercially available mining cost estimating software and mineral processing models of Camm (1991). This paper assesses two methods of cost-modeling for open-pit mining and heap-leaching of copper ores with copper recovery by solvent-extraction and electrowinning (SX/EW).

The estimation of dilution and ore loss is therefore an essential part of any Ore Reserve estimate or mine schedule. Large open pit mines are driven by the economies of scale that are achieved at the cost of less selectivity in the discrimination of ore and waste.

In 2014, the current open pit operation produced 340.4kt of fine copper in cathode and copper concentrate and 14.6kt molybdenum, 757t gold, 186.9t silver and 1.0 million tonnes of sulphuric acid at C1 copper cash costs of approximately USD0.90/lb. Current mine reserves stand at 0.902 Bt grading 0.83% copper. The mine operates as an open pit but

For small capacity mines, 40% of the capital cost of the large capacity mine is used based on trends seen in the capital cost calculation for refining. The variable portion of the cost calculation is based on the open pit mining models published by the USGS, which take into account several factors that affect capital expenditures (Camm, 1991).
The open-pit mine produced 443,000t of copper in 2011. Feasibility study is underway to switch to underground production at Chuquicamata by the end of 2018. The ore reserve under the existing pit is estimated to be 1.7 billion tonnes grading at 0.7% copper. The underground development project is estimated to cost more than $4bn.
Typical open cut grades. Gold is generally extracted in open-pit mines at 1 to 5 ppm (parts per million) but in certain cases, 0.75 ppm gold is economical. This was achieved by bulk heap leaching at the Peak Hill mine in western New South Wales, near Dubbo, Australia.. Nickel, generally as laterite, is extracted via open-pit down to 0.2%. Copper can be extracted at grades as low as 0.11% to 0.2%.
Labour Production Costs Non Labour Production Costs Coal Price PwC Productivity Index 1995 to 2011 (Base Year = 1995, Base = 1000) which is in large part due to the falling productivity of the mining industry Australia has some of the world’s largest coal reserves, but is struggling with maintaining mining profit margins.
