Took 3 months for Banro to solve the same problem! Ok. This is not rocket science. Call up your partner Barrick. Get a used agglomeration drum. Put in some conveyors and move the ore from the current leach pad to a newer smaller pad.
It might take a year to get all the gold but it will be worth 3X current share price.
From the Banro website:
"January 2015. Site civil work for the installation of the drum, its feed conveyors and other ancillary equipment commenced in November and commissioning completion is scheduled for mid-February 2015.
''The inclusion of the agglomeration stage (with cement added as a binder) into the Namoya heap leach circuit is expected to allow for more efficient processing of the fines content of the Namoya ore and ensure more efficient reagent percolation in the heap process, leading to better gold recovery," commented Banro CEO and President John Clarke.
''With the completion of Q1 2015, the Twangiza mine has achieved three quarters of consistent and improving gold production. Twangiza's improving production profile indicates that Twangiza is maturing into a stable low-cost mine. We are also very pleased with the progress at Namoya, where the commissioning of the agglomeration drum has led to improvements in the quality of stacked material, which in turn is supporting the ramp-up towards commercial operations," commented Banro CEO and President John Clarke.
