Estimates of the overnight capital cost, fixed and variable operations and maintenance costs, and plant heat rates for generic generating technologies serve as a starting point for developing the total cost of new generating capacity. However, other parameters also play a key role in determining the total capital costs.

In general, mining specialists divide mining costs in open-pit mines into three classes: capital expenditure, operating costs, and general and administrative costs. In this classification, capital costs refer to the investment required for the mine and mineral processing plant.
The Real Cost of Mining Gold. Since the bull market for gold began in 2003, the world's major gold mining companies have produced tens of millions of ounces of gold and have raised (and written-off) many billions of dollars for capital expenditures and acquisitions. Despite a gold price that appreciated from $344 to $1260 an ounce from 2003 ...

Capital Costs – IRR 56.9% 50.3% 45.8% 40.2% 36.1% Capital and Operating Costs The Los Ricos South Project has been envisioned as a combined open pit and underground mining operation, with contract open pit mining in years one to six of the mine plan, and contract underground mining in years six to eleven.
and share number of open pit mines have provided the opportunity for manufacturing open pit equipment in large numbers, thus reducing production costs even further. Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive.
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 Initial Capital Cost of the Project is US$ 1,214.7 million comprising US$ 982.5 million for the mine and US$ 232.2 million for the concentrate transport system that delivers product to the deepwater Port of Saguenay open 365 days per year.
If cost evaluations of essential mine operations are available (such as ore mining, waste removal, ore concentration, transportation, indirect project costs and expected concentrate selling prices), the methodology will provide clear indications on the economic feasibility of mining, including the best available options at any moment.
The NLGP current mine plan (Stage One Onsite Mining & Processing) consists of three open pit gold deposits: Bungarra, Boundary and Stirling, all located within a 5km radius resulting in optimal mine scheduling, optimal mill blending and shared capital and operating costs.
