Bentonstocks ............... On your point of P George identifying no inferred resources category - see old (2006) treatment of inferred in an estimate for the Bloom Lake iron ore mine in QC. Inferred is included in the strip ratio and wasted.

The Mineral Reserves contained in the detailed pit design amount to 463.4 million tonnes in the
Proven category and 116.2 million tonnes in the Probable category for a total combined of 579.6
million tonnes at a grade of 38.2% hematite weight recovery and 30.0% total Fe based on a cutoff
of 15%. The stripping estimate, including Inferred Resource material, is 563.8 million tonnes
for an overall mine-life stripping ratio of 0.97 tonnes of waste per tonne of ore.
