Economies of Scale in Gold Mining

suggest that economies of scale is present in the gold mining industry. This means that the trends observed in large-scale mining, as well as mergers and acquisitions in the industry are likely driven by economies of scale. 2.

An Estimation of the Artisanal Small-Scale Production of

The increase in gold price of over 400% between 2002 and 2012, due to a shift towards safe investments in a period of crisis in the global economy, created a rapid increase in gold production. A response to this shift in production was observed for artisanal and small-scale mining (ASM) units in remote locations of the world, but this phenomenon has not been quantified yet. The work presented
