Hi grade resource

2.11 grams per tonne is something we are all used to hearing, each time that DR talks it is mentioned but it was only today that I realised just how high a grade that actually is looking at a graph of in ground resources for open pit mining. The chart started at 0.35 g a tonne then a further 12 increments steadily climbing and finished at 0.196 g per tonne. This inferred to me for an open pit resource from surface we have gold grades fit for an underground mine
