@Wombat, I think @bobbym had a touch of sarcasm in his comment.
Now, it's good you are keeping it balanced..Let's see, for every 100 metres of drilling, you are coming up with 110oz. Well Estelle must be the Lihir deposit on mega steroids?
Are you getting these calculations from the company or are you just picking pie in the sky figures.

Can I suggest you go and have a look at Freeports Grazburg deposit in West Papua, and the Lihir deposit on Lihir Island .Have a good look at the early exploration and pay particular attention to the meterage these companies drilled to prove up their mega resources.
Then, look at your calculations, if correct, this is the biggest gold deposit in the entire universe, unless of course they are drilling directly into King Solomon's buried gold war chest, or the buried Spanish gallion gold booty that noone knew existed.Then of course that would explain your 100 metres of drilling for 110 oz gold lol.
Of course, I am glad you mentions desktop analysis, field work and bit of historic data?
