re: cut-off grade of 3 g/t Au used for 1.6M oz MI&I Au resource...

If you use some simple trend line techniques you can extrapolate estimates for the resource at lower cut-off grades (i.e. 1g/t and 2g/t)... using detailed chart in GGR presentation I come up with a MI&I resource of...

Cut-off grade @ 2g/t... about 1.75-2M oz Au @ ~4.5-5g/t Au

Cut-off grade @ 1g/t... about 2-2.5M oz Au @ ~3-4g/t Au

Rough estimates I know (quick and dirty) but significant increases in the resource just by including some lower cut-off grades (i.e. ones that are being used by most every miner these days).

Not a bad payoff for no additional work... I would be we may see release on this in good time.
