RE:RE:It helps to read the footnotes in the technical reportsNostradamusII,
What I am saying is that if you do a mass balance of the 2016 copper resource, Orvana reported a copper resource of 9284 in situ metric tons. In fiscal 2017, Don Mario processed 6349 metric tons, leaving a balance of 2935 metric tons. Don Mario processed 5179 metric tons of copper in 2018, so where did the 2244 extra metric tons of copper come from?
IMHO, the answer is the oxide stockpile where oxide ore was being blended in to the flotation process in 2017 and 2018, and so that explains the 5 percent drop in the mass of the oxide stockpile. The mass balance between the 2016 gold resource and ounces produced results in a surplus of 3311 ounces of gold or roughly 2 percent more gold than they reported in the 2016 Annual Information Report. Where did the extra gold production come from? The likely answer is the oxide stockpile.
There is no mystery or men in black trucking ore out the back door at night!
