Rexma closer to mining at Marudi

Of interesting note are a few key points:
1) a major gold mining project in southern Guyana is set to gain approval to begin operations 30 days from April 30th (the last meeting with the locals)
2) No chemicals will be used and the project will serve as a demonstration of non-chemical recovery of gold from placer deposits (fascinating without the use of Cyanida- Go David!)
3) It is expected that the mine will operate 10 hours each work day and will process 600 cubic metres of mineralized gravel each day. The equipment has been sized to operate for 350 days per year. Average production will be 200,000 cubic metres per year at the beginning of the operation and this will increase to 400,000 cubic metres annually in year two, and this production level will be maintained for the remainder of the operation.
At 1.2 g/tonne this represtents almost $1 million to the coffers of SMH in the 1st year alone. Plus, ALL of the work done at Marudi counts in for the 75%. Niice!
4) As regards ore recovery, the alluvial deposit will be mined by open pit methods in the creeks’ flats. Gold will be recovered by gravity separation using mobile screen and concentrator units. This will allow rehabilitation of mined out areas to occur as work advances. (North american mining methods. How nice).
