Aug 26, 2021 Phase one will consist of an open pit mine and underground mine that will operate for 10 years. Phase 2 consists of mining from underground for a further 13 years. The company is currently in the midst of updating the feasibility study at Skouries updating the capital cost estimate. The last capital cost estimate was 700 million.
Because the cost data used to estimate operating and capital costs in these models are now over ten years old, we decided that it was necessary to test these equations with more current data. We limited this study to open-pit gold-silver mines located in the United States.
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.
May 01, 2017 This paper analyzes an open pit gold mine project based on the OHara cost model. Hypothetical data is proposed based on different authors that have studied open pit gold projects, and variations are proposed according to the probability distributions associated to key variables affecting the NPV, like production level, ore grade, price of ore, and others, so as to see what if, in a gold ...
Capital Costs The capital cost estimate for the proposed open pit operation is based on the scheduled plant throughput rates, as well as a review of similar sized open pit gold operations. Capital Cost
Apr 09, 2017 The cost of this preparatory work is obviously a charge against the cost of mining the ore, each ton of which must bear its proportionate share. As the stripping-ore ratio volume or tons of overburden and capping to tons of ore made available for open-pit mining increases, obviously the cost of stripping per ton of ore increases.

PEA Results. Preliminary Economic Assessment overview . The PEA for the Troilus Gold Project supports a combined open pitunderground mining scenario with low initial capital costs and high rate of return for a 35,000 tonnes per day tpd operation over a 22-year mine life.
Jun 20, 2019 But it didnt. In 2001 when the gold price was just 272oz, gold mining companies had cash costs of 176 an ounce, giving a 54 margin. However, by 2006 the gold price climbed into the 600 an ounce range and miners were losing money. Fast forward to 2012, when the average cash cost was 719oz - 184 higher than 2006.
