Scale, grades, processing costs, open pit vs underground. The interesting aspect of the AISC metric is the number of factors that feed into the final figure, and similar to any other sector costs, they can vary from month to month and year to year. In the case of gold stocks, better grades usually translate into lower cost mines.

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.
Gold is a rare element, and much of the worlds supply of easily attainable gold was picked up, mined, and prospected long ago. Even though mining efforts are much more sophisticated than they used to be, finding new sources of goldand cost-effectively mining themgrows more challenging each year.
Capital cost breakdown is shown in Table 25.2 for a typical developing country, covering remote sites with minimal infrastructure and minimal redundancy. Each operation, of course, will have a unique mix of capital cost line items. ... KCA has built and installed over 35 modular plants for the processing of gold and silver ores using the ...
Gold mines produce rough gold, called a dore bar. These bars are typically about 80 percent pure gold. The gold is then sent to a refinery, where it is refined into gold of different forms and purity.

2020-3-23Both these process routes come with a high installed capital cost and ongoing high operating costs, but both can achieve very high gold recoveries. The problem is that to justify the high capital and operating costs, mining projects require multi-million-ounce resources to be proven with a long mine life to get a return on capital.
The guide includes both CAPITAL COSTS and HOURLY OPERATING COSTS for over 3,000 pieces of equipment commonly found in mines and mills around the world from 500 slusher buckets to 50,000,000 walking draglines.
