Nov 15, 2019 Summary. Cost curves are a useful tool to analyze firm behavior. In most cases, we can observe three properties of cost curves: (1) The marginal cost curve eventually rises as output increases, (2) the average total cost curve is U-shaped, and (3) the marginal cost curve intersects the average total curve at its bottom.

The unique and dynamic nature of a mining operation can make it challenging to establish consistent operating costs. Overall operating costs for hard rock mines can vary between US $5 to $100/tonne depending on the scale of operations and the mining method that is employed.

tool based on cost curves is freely available and provides touch-of-a-button visualization for all these questions.2 The paper is organized around these questions. After a brief review of ROC curves (see Fawcett (2003) for a more in-depth tutorial), cost curves are introduced. Then a section is devoted to each of the questions.

Jun 30, 2021 Costs in the gold mining industry increased for the second consecutive quarter in Q1’21, with the global average All-in Sustaining Cost (AISC) up by 5% q-o-q to US$1,048/oz, reaching its highest level since Q2’13. This, combined with a 4% fall in the average quarterly gold price, resulted in a 14% drop in AISC margins (the gold price minus AISC) between Q4’20 and …
