For Roan, the DMS production capacity was always based on a feed grade of 1.5%, thats what the numbers on the flow diagram on the Jubilee website were based on. Based on a recovery percentage of about 55% they should achieve 5,000 tonnes per year from the DMS circuit alone. If they have the glycine leaching at Roan as well that recovery could be around 70%, so about 6000 tonnes per year. We don't know much about the milling and floatation circuit, how much of the capacity is being utilised? What is the feed grade? How much is being produced? All questions that I think we need answers to.
From Munkoyo, they are aiming for 8,500 tpm of feed at >2.5% direct to Sable for leaching and electrowinning. At 90% recovery and 3% grade that would be about 2,750 tonnes per year of cathode. The leaching will add to that, whenever that goes ahead.
Project G should have been operating at 10,000 tpm through the on site concentrator to produce 3,000 tpm of concentrate at between 10-15% copper grade. That would equate to about 3000 tonnes per year of cathode.
That is more than enough to fill the current cathode capacity until they complete the second tank house later in the year. They can always sell excess concentrate until such time as they can process it at Sable.
