To record depletion, debit a Depletion account and credit an Accumulated Depletion account, which is a contra account to the natural resource asset account.get price
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.get price

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on theget price

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).get price
May 21, 2013 The political stability of a nation can turn on one election and so can the prospects for developing a mine. An anti-mining leader can halt a mining project, or a pro-mining leader can usher forward one. A positive national viewpoint on mining may be enough to lure investment dollars, but local politics may determine the success of a miningget price
The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports.get price
