Executive SummaryThis reserve estimate is produced for Tasmania Mines for annual reporting and audit purposes. The Kara No 1 reserve has been estimated based upon the January 2017 digital resource model as described in both the December 2014 Kara No 1 Resource report and January 2017 technical memorandum (Resource and Exploration Geology) utilising an FeO>30% mineralised cut off (see Appendix 6). References to global in-situ resource in this report correspond to the January 2017 digital resource model.
Reference to minable resource referred to in this report represents the FeO>30% component of the global in-situ resource that lies above the current pit life of mine (LOM) pit DTM and which has not been sterilised by its location.
- Kara No 1 Global Resource is 14,600,000 tonnes at 49.5% FeO
- Kara No 1 Minable Resource is 10,304,000 tonnes at 50.2% FeO
- Kara No 1 Total Ore Reserve is 9,974,000 tonnes at 49.7% FeO
The Kara No 1 pit life based upon the current production rate of 400,000 tonnes of ore per annum is 25 years.
This reserve estimate is derived from sectional perimeters which represent realistic mining shapes and include planned waste and low grade dilution. Reserve perimeter sets utilise, but are not wholly constrained by, the LOM pit shape as a guide. The reserve estimate excludes 95,000 tonnes of inferred resources (59.5% FeO) that lie within the LOM pit boundary and will be mined during the normal operation of the open pit.
It is estimated that 7% of the material reporting to the reserve within the pit design shell contains material classified as oxidised. It is currently considered that up to 30% of this oxidised material is unsuitable for generation of a magnetite product and may have weathered to limonite, goethite, haematite etc. The estimate for oxide material has been adjusted in this reserve estimate accordingly and a 30% reduction factor is applied to oxide reserve estimates reflecting current applied practice in the open cut which indicates an increased throughput of oxidised ore compared to 2014 and 2015.
