From 07.11.24
The Front-End Module is capable of operating as a stand-alone unit or as an integrated processing unit together with the existing Roan Milling and Floatation operation. This adds tremendous flexibility to the Roan operation capable of successfully addressing fluctuations in feed quality to ensure the production of a consistent high grade copper concentrate for either further refining or direct trade into the market.
The upgrade enhances Roan's processing capacity to a combined maximum of 13k tpa of copper, depending on feed grades (assuming a feed grade of 1.55% copper and run rate of 90ktpm).
The integrated Roan facility targets an initial stable feed rate of 75k tpm of material over the first three quarters of operation, with the potential to increase to a feed rate of 90k tpm thereafter. An initial copper recovery of 55% copper in feed is targeted before the introduction of leaching at Roan which is expected to increase copper recoveries to in excess of 70%. This translates to an initial copper unit production from Roan, prior to leaching, of approximately 520 tpm of copper with the potential to increase to 670 tpm assuming the lower feed rate of 75 000 tpm is maintained. Roan's capacity remains dedicated to the processing of previously mined material.
