Republic Gold Limited’s vision is to become a leading gold explorer and producer, focusing on gold deposits in Bolivia's and Australia’s slate belt gold provinces. The Directors of Republic Gold offer what they believe is an attractive portfolio of tenements in southern Bolivia, the Hodgkinson Basin in Far North Queensland and in the Lachlan Fold Belt in Central New South Wales.
Republic Gold can increase gold recoveries at Amayapampa
Queensland-based gold miner Republic Gold (ASX: RAU) reported that testwork undertaken at the Amayapampa Gold Project in Bolivia, has improved metallurgical recoveries.
First pass gravity and intensive leach metallurgical testwork completed by Gekko Systems of Ballarat for primary mineralisation showed consistently high recoveries and indicated that at a 15% concentrate yield by weight - the average metallurgical recovery increased over the previous average recoveries by 3.5% to 86.6%.
Oxide metallurgical recoveries were more variable, as experienced in the earlier testwork, and the average recovery dropped by 1.6% to 82.8%.
Based on the current work and current resource at Amayapampa, the primary and transition portion of the 1.1Moz mineral resource equates to 92% of the total resource.
Hence, a 3.5% improvement for the primary mineralisation and a 1.9% improvement for transition mineralisation (the average of the oxide and primary recoveries) will have a significant positive benefit to cash flow for the Project.
This could potentially add in excess of 15,000 ounces to gold inventory, depending on resource to reserve conversion.
The recovery of the additional ounces would be for no cost. The oxide portion of the total resource equates to approximately 89,000 ounces and equates to the potential loss of less than 2,000 ounces only.
Gekko will now perform optimisation testwork that will be done to potentially enhance these recoveries.
A Scoping Study will follow that will feed into the treatment plant portion of the Definitive Feasibility Study.
Republic managing director John Kelly said today “the receipt of the overall positive results from Gekko is a vitally important step forward for the Project."
"We can progress to complete the treatment plant portion of the Feasibility Study and commence more meaningful open pit optimisation work.”
