RE:RE:BUYOUT2fast4ul,
You are right about the AISC in 2007 was around $250 USD. However, Orvana only had a 700 tpd plant with a CIL, and needed 4 g/t gold to break even at that production rate. Their cutoff grade for gold ore was 3 g/t. The price of gold in 2007 was $650 USD per ounce so the margins per ounce of gold production were $400 USD in round numbers.
Fast forward 11 years later and Don Mario can process 2200 tpd, has a gravity circuit with the ability to recover gravity gold and copper with 3 Falcon centrifugal concentrators. There have the capability to process sulfide ores with multiple flotation circuits and even have an idle sulfuric acid plant which can be used to restart the LPF.
At El Valle they also have another 2200 tpd plant with the capability to process both oxide and sulfide ore simultaneously and produce a copper and silver by product.
With 6 times the production capacity it only takes a $100 USD move in the price of gold to make the same profit as they did in 2007, and they can do it with a much lower gold head grade. So this quarter's numbers should be real interesting.
