The crushing circuit was purchased from EMS/Index Australia, was designed by Trio in the United States, and is capable of crushing up to 5 millions tonnes of ore per annum depending on the final crush size and operating configuration. For example, if the final-crush size is increased to -50mm (from the current -38mm), throughput increases to around 5.7 million tonnes per annum. The Crushing Circuit will initially operate at just 3 millions tonnes per annum, comfortably under nameplate throughput capacity. The company is also investigating the option of beneficiation of mined ore prior to mill-feed, utilising specially designed ore-sorters that will at least double the grade of mill-feed ore presented to the mill. Whilst these ore-sorters are capable of generating beneficiated ore to well over 20%, the plan is to limit this to between 2.5-3% head-grades. Associated high-grade coarse native copper will be additional to the above, as the Rocklands plant is capable of accepting head grades up to 25% Cu (20% native copper and 5% other ore types concurrently).
