USGS releases first study to assess global earthquake risk to mineral supplies
Earthquakes have the potential to substantially affect mining operations, leading to supply chain disruptions that adversely affect the global economy.
Perseus Mining (ASX, TSX: PRU) said Wednesday gold production at its Edikan gold mine in Ghana will be less than the 58,500 ounces projected in late November for the December 2012 quarter.
According to the press release, the company now estimates gold output for the period will be only 49,000 ounces.
Perseus blamed low crusher productivity followed by a much longer than expected shutdown of eight days in December for the liner change and remedial work.
The production shortfall was exacerbated by a shortage of crushed material on the coarse ore stockpile to feed the mill during the crusher shutdown and lower recoveries largely attributable to milling a higher proportion of oxide ore to compensate for the lack of crushed primary ore.
The gold miner expects to provide an operational update in mid-January.
