| ABSTRACT: | Carrapateena Project Mineral Resource Restatement and Ore Reserve Statement Please find enclosed the Carrapateena Ore Reserve Statement as at 4 August 2017. As the Ore Reserve Statement is based on the Carrapateena Project Mineral Resource estimate as at 18 November 2016 released to the ASX on 9 December 2016 that Mineral Resource Statement is also enclosed with this release for ease of reference. The Carrapateena 2016 Mineral Resource Statement relates to an updated Mineral Resource estimate for the Carrapateena copper-gold deposit, an iron oxide copper-gold (IOCG) deposit located in central South Australia on the eastern margin of the Gawler Craton. The estimated Mineral Resource for the Carrapateena deposit is shown in Table 1. The Mineral Resource estimate has been reported in accordance with the 2012 edition of the JORC Code. The Mineral Resource estimate is based on data from 106 drill holes (including 31 wedges) for a total of 60,809 samples in mineralised domains and is an update to the restated 2015 Mineral Resource as at 17 October 2016. The geological interpretation and estimation parameters have been revisited. A nominal cut-off of A$70 per tonne net smelter return2 (NSR) has been used to generate a continuity shape in which all material was deemed to have reasonable prospects of eventual economic extraction. This Ore Reserve estimate is based on the Carrapateena 2016 Mineral Resource estimate as at 18 November 2016, originally released to the ASX on 9th December 2016, and re-attached to this report for ease of reference. A Pre-Feasibility Study was completed during 2016 on the previously released 2015 Mineral Resource estimate as at 25 September 2015, released to the ASX on 6 October 2015. The PreFeasibility Study has been updated for the 2016 Mineral Resource Estimate, including a revision to the mine access and material handling system, and modifications to the mining footprint where required. Based on the mining and processing schedules completed for the study update, together with ongoing metallurgical test-work, the Carrapateena Project is no longer reliant on the incorporation of a Concentrate Treatment Plant (CTP), and has not been included. | |
