Working capital, based on 2 months of operating costs, was included in the capital cost of each mine and mill model. Working capital covers the cost of meeting operating costs in the initial stages of production, before revenue is generated from the first shipments of product (concentrates or dote). This value can vary from. 2 to 6 months.
Like other producers, in 2012 we faced increased pressure on capital costs, operating costs, and operating margins. These and other factors contributed to an erosion of investor confidence, and a decline in share price performance for the entire sector.

In a recent publication (SAG 2015), we presented a non-conventional HPGR-Ball mill circuit as a lower capital cost alternative to the "standard" HPGR circuit. The circuit was designed for the treatment of a hard ore and relatively high tonnage (50,000 t/d). That paper provided details such as flowsheets, layouts, and equipment lists for the ...

By evaluating the capital and life-of-mine operating costs of competing circuit designs for soft, medium and hard ores, the HPGR break-even point can be identified, at which the incremental capital cost of an HPGR circuit is equivalent to the net present value of the projected operating cost reductions. ... while for softer ores, SAG mill/ball ...
The indirect cost was estimated at 45% of direct capital costs and was considered to be within industry standards for the options considered. A similar approach was applied to estimate the total direct costs. It was found that both HPGR-ball mill and HPGR-stirred mill circuits have higher associated capital costs than the SABC option.
Lower capital cost. Vertimill® requires a simple and small foundation, which means less floor space is required. In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine.
