Continental Gold Limited (TSX:CNL, OTCQX:CGOOF) announced results from metallurgical testing at the Buriticá project Colombia.
As quoted in the press release:
- Gravity concentration followed by cyanidation of gravity tails on all four 150 kilogram samples submitted for test work yielded overall metallurgical recoveries of 95.4% and 48.6% for gold and silver, respectively.
- A large proportion of the gold can be extracted using gravity separation with an average recovery rate of 73.8%. This recovery rate was achieved with a grind size of 80% passing 75 microns.
- High gold recovery rates were also achieved in the two other processing routes tested, namely gravity concentration followed by flotation and leaching of the concentrate and gravity concentration followed by Carbon In Leach.
Continental Gold’s President and COO, Mark Moseley-Williams, said:
The cyanidation of gravity tails process achieved consistently high gold recoveries for all of the composites tested. The process is inherently simpler than the flotation route. All of the tailings will be filtered for dry stacking, so environmental management will be readily manageable within acceptable parameters.
