| ABSTRACT: | This Mineral Resource Statement is an update to the restated 2016 Mineral Resource as at 18 November 20161 . This update is not based on any drilling since the previous estimate but has been made to reflect minor changes to price and exchange rate assumptions and the need to assess the amenability of the resource to exploitation by Block-Caving. The Mineral Resource estimate is intended to be suitable as a basis for assessing a Sub-Level Cave (SLC) mining operation in the upper levels and a Block Cave (BC) mining operation in the lower levels. Mineral Resource 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. For mineralisation above the 4,200m RL, a nominal cut-off of A$70 per tonne simplified net smelter return2 (NSR) has been used to generate a continuous shape3 in which all material was deemed to have reasonable prospects of eventual economic extraction, assuming a SLC operation. For mineralisation between the 3,600m RL and the 4,200m RL, a nominal cut-off of A$20 per tonne simplified NSR has been used to generate a continuous shape in which all material was deemed to have reasonable prospects of eventual economic extraction assuming a BC operation. | |
