Metallurgical Test Work undertaken at B2Gold’s Mines confirms 95.4% Metallurgical Recovery from samples within the Permitted La India Open Pit
Condor Gold (AIM: CNR; TSX: COG) is pleased to announce recent metallurgical test work conducted by B2Gold Inc. (“B2Gold”) on behalf of the Company from samples taken from an area withinthepermitted La India open pit. Two samples of approximately 23kg each produced an average head grade of 12.1 g/t gold and average metallurgical gold recoveries of 95.4%. This confirms the suitability of La India ores to be processed at B2Gold’s processing plants in Nicaragua or a similar processing plant. The gold recoveries are better than previous metallurgical sampling compiled for the 2014 Preliminary Feasibility Study (“PFS”).
Mark Child, Chairman and CEO of Condor Gold, commented:
“First, I would like to thank B2Gold for their cooperation and allowing Condor Gold to conduct metallurgical tests on mineralised ore sampled by B2Gold’s personnel from within the permitted La India open pit at laboratories at both their mines in Nicaragua. Secondly, I am delighted with the exceptional gold recoveries of 95.4% as it confirms the suitability of La India ores to be processed at B2Gold’s processing plants. The high grade samples, producing an average head grade of 12.1 g/t gold, were taken from the principal La India Vein. It is invaluable to conduct metallurgical test work at two nearby producing gold mines whose laboratories are set up to replicate the metallurgical recoveries at the mines. It assists Condor in deciding on a final mine design and metallurgical process as the La India Project progresses to the construction phase.”
Background
On behalf of Condor, SRK Consulting (US) Inc. (“SRK”) designed and supervised a metallurgical test development programme as part of the December 2014 PFS on the mineralised material taken from drill core from La India and America Vein Sets using the independent laboratories of Bureau Veritas in Richmond, Canada. These tests were completed to a PFS level of metallurgical study and are intended to determine the most effective and efficient means of extracting gold and silver from the mineralised material. The SRK analysis indicated that the ores were amenable to Carbon-in Pulp (“CIP”) or Carbon-in-Leach (“CIL”) methods. Gold recovery from La India Vein Set was estimated at 90% to 92%, which includes a 2% reduction to allow for plant inefficiencies. Reagent consumptions were also tested, indicating consumption of 0.75 to 1.5 kg/t of sodium cyanide and lime consumption of 1.0 to 1.5 kg/t. La India Vein Set ores were noted as harder than usual with the Bond Ball mill work index determinations ranging from 17.5 to 21.9kWh/t. Grind-recovery test work indicated that a grind of 80% passing (P80) 75 microns will be required.
Recently, as a part of Condor’s on-going investigations of the La India ores, staff from B
