Ann: 40m at 7.2 g/t au from 192m extends Lady Julie North 4, page-7

I am not sure how you got these figures.

We have 1.8B worth of gold on the ground and we are trading at 180M. That's a 10% of the value in the ground. Shallow mine, with a cut-off of 0.5g/t. Let's say 700$ operating costs per oz (that's a high figure closer to underground, but let's just assume it's true). If we consider gold will stay at $3000 per oz (which most likely won't), that's still 1.38B of profit

Considering that mineral resources don't increase at all (which will likely do considering how rich and uniform the ground is) and considering that gold stays the same (forecasted to go considerably up from here), as a base scenario, I see tons of upside here.

Though to be honest I don't think MAU will mine this and we will sell the deposit to one of the big goldies for a juicy figure.
