FFF, what are your views on the production numbers that CAM gave on the show?
I believe he is being super conservative due to the problems over the last year.
As Dave McMullin stated Hidden Treasure contains 1.7% copper.
Therefore ore input of 2250 tonnes per day will contain 38.25 tonnes of 100% copper. Which is 84,150 pounds.
CAM stated that at this input the amount of concentration produced will be 25 tonnes. Lets assume that this contains 30% copper (as per previous numbers from the mill). Therefore this is 7.5 tonnes of 100% copper which is 16,500 pounds.
Therefore the flotation process is only extracting 19.61% of the copper in the ore.
Originally i heard the number they were shooting for was between 60-65% with a further 30% being extracted from the copper tailings by the SX/EW or cementation process. Therefore extracting about 90-95% of the copper in the ore.
So at an ore input of 2250 tonnes, the flotation mill should produce about 75 tonnes of Concentrate at 30% copper. Triple the 25 tonnes figure stated.
I suspect Charles is following his principle of under promising and over delivering. Which i can understand but i think there is serious upside. Thoughts?
EDIT: imagine what the figures will be with 3375 tonnes of ore input.
