Ann: Far West Reserve and Resource Update Extends Mine Life, page-19

LOM is based on Reserves ONLY. This was a Resource upgrade. Reserves are a subset of resources and take into account the economics of extraction. While you technically need to wait for the Reserve upgrade to get the LOM update (LOM = Reserves/Annual throughput), you could reasonably in this instance apply a 90% factor to the Resources to calculate LOM, ie LOM = (Resources x 90%/Annual throughput). The 90% come from the fact that most of the Resources are likely to be economic to mine.
