Semi-refractory Ore, page-9

Kalgoorlie Consolidated Gold Mines Pty Ltd (KCGM) operates the Gidji Gold Processing Plant (the Gidji Project) which is located approximately 17 km north of the City of KalgoorlieBoulder. The plant treats refractory sulphide ore concentrate which is transported by road from KCGM’s Fimiston Processing Plant. In 2015 the two Satellite Roasters which previously operated at the plant to process the concentrate were decommissioned, following installation of a second UFG mill. As a result of these changes KCGM made an application in April 2015 to rationalise and contemporise conditions of Gidji Ministerial Statements No. 28 and 77. During May 2016 the Environmental Protection Authority (EPA) released its report and recommendations on the proposed amendments to the statements (EPA Report No:1566) and in June 2016 published Ministerial Statement No. 1032 (1032:M), approving the changes under Part IV of the Environmental Protection Act 1986. The Gidji Project infrastructure includes: • A carbon-in-pulp (CIP) circuit; • Two Ultra Fine Grinding (UFG) mills (Isa Mill M3000 and Isa Mill M10000) with a combined production throughput of 438,000 tonnes per annum (tpa); • Tailings storage facilities (TSFs); and • Associated infrastructure. The Gidji Project is expected to continue operating until 2029
