influence of different mining methods on capital and operating costs, including the breakdown of the costs were then discussed. The chapter concludes by discussing the purpose and the context of this study, the problem statement and the delimitation of this study. Mining overview
Lifeofmine capital expenditure, inclusive of preproduction costs, mining capital development and sustaining property, plant and equipment (PPE), but excluding closure costs, is estimated to be 235M (Table 6). The estimated annual capital expenditure profile is shown in Figure 5. Costs are as at September 2017.

Aventurine Engineering designs and produces software used by cost estimators in the minerals industry. Our Sherpa line of programs is designed to estimate the capital and operating costs associated with underground, surface and placer mines, and we have recently released a program designed specifically to estimate the costs of reclaiming mine sites.
Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
consideration that include: cost of fuel, capital costs, and operating and maintenance costs. Note, the following cost estimates will use 2011 USD values. The cost of fuel spans the entire production process of reactorready uranium pellets, starting from mining through enrichment. Uranium ore is typically mined as UO 2, UO 3, and U 2O 5. These
In the feasibility study you should look for the expected CAPital EXpenses (CAPEX) and OPerational EXpenses (OPEX) to inform yourself about the mining costs of the specific project. Capital Expenditures (CAPEX) Capital expenditures are the investments incurred by a mining company in their fixed assets to increase the value of that asset. Most ...
A generic mining cost structure There are two main types of costs for mining projects – operating and capital costs. Figure 1 is a schematic representation of the generic cost breakdown for mines. A brief overview of what these costs entail is discussed in the following sections. Capital costs Capital costs in mines can be split into startup
the economics of gold mining. Allin sustaining costs is an extension of the existing "cash cost" metrics and incorporates costs related to sustaining production. Allin costs include all additional costs that reflect the varying costs of producing gold over the lifecycle of a mine. Inconsistency in cash cost reporting among gold
In 2013, the industry implemented a new and moreinclusive cost reporting measure called "allin sustaining costs". Despite this attempt to include more expense and capital items, the real costs of mining gold remain opaque. As of this writing, there remains no standardized cost reporting in the mining .

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.
The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore contains more copper, it requires less of these inputs
