RE:RE:Repost of Kentors Update on Heap leaching MurchisonThe short answer is YES.
I quote.he current production plan would have the heap leach facility circuit commencing operation first followed by the CIL circuit. A heap leach facility will allow a higher grade cut off to be used for the CIL, ensuring that only high grade ore is directed to the CIL plant. Lower grade material would be directed to a heap leach, so that the contained gold could be recovered economically.
Heap Leach Engineering
A crucial phase in the start-up of heap leach facilities at the Burnakura site is now complete. Como Engineers (“COMO”), a Perth based engineering company, have finalized the Front End Engineering Design (“FEED”) Report. From supplied metallurgical data, it contains details for the design criteria, equipment lists, flowsheets, drawings, CAPEX, OPEX and schedules for COMO to supervise and assist refurbishing, constructing and commissioning of the heap leach plant.
A major breakthrough for the project from the FEED report is the final crushing circuit configuration, with a design that has the capability of crushing the material for the heap leach facility and the Carbon in Leach (“CIL”) plant when it is put back into production. Long lead items, such as quality refurbished secondary and tertiary crushers have been procured within Australia having the extra advantage of arriving in time to crush material for the construction of the heap leach pad.
The plant and fixed assets have been kept in good care and maintenance order with a view to future commissioning. Site operations are fully functional for COMO to start construction works. Refurbishing, constructing and commissioning will take approximately six months.
