The feasibility study anticipates initial production from the Serra and Meio veins, the 2016 work program will include infill drilling along these veins to confirm and upgrade existing resources. This work will also support additional metallurgical testing, and development of final mine plan and schedule for the Coringa underground mine. Geotechnical siting work will also be completed on the process plant and tailings facility.
Previous drilling by Magellan Minerals was focused on a 5 by 7 km area with known vein systems and historic workings. To date, a total of 179 holes - 28,436 metres been completed
Three phases of metallurgical test work have been done on composite samples prepared from drill core that intersected quartz vein mineralization on the Coringa project.
2 composite samples were taken from each vein, as follows:
Meio - Galena - Serra
Belo Horizonte, Brazil
Gravimetric separation followed by floatation would provide best gold recoveries
Meio - Serra
RDI, Denver, Colorado USA
Conventional CIL milling circuit best treatment for gold recovery. Serra & Meio gold recoveries 99% and 97.7% respectively
Meio - Galena - Serra Como Quieto - Mae de Leite
Testwork Desenvolviment de Processo, Nova Lima, Brazil
