Trial open cut mining planned: ~100Koz pa Au at a conservative 1oz/t Au, page-124

"If the upcoming drilling results yield anything close to the 58.16g/t Ema surface samples"

There's a huge, crucial difference between the Tres-Ema deposit and, for example, a certain WA explorer that announced their "HIGHEST GRADE INTERCEPT" in upper case today as part of a resource drillout.

People get excited when they see a big number and start thinking that there's masses of ore at those grades there but it's precisely the opposite. That highest grade is an outlier statistically speaking and will get top cut to a much smaller number during the resource estimation.

Although it suggests that there is some good grades there, all they've done is snag a nugget or a rich pocket of high grade. There'll probably be more nice patches but it won't add up to a lot of tonnes at those grades.
At Tres-Ema, (and at Juma) they have said a few times that mineralisation is likely to be evenly spread through the rockmass.

Because of this and the very fine nature of the mineralisation, there will be no nugget effect (http://geochemist.com/papers_cpt/es...alyses-in-samples-exhibiting-a-nugget-effect/) and the grades we get from sampling whether it be bulk sampling or drilling will be reliable instead of erratic, which is more typical for gold deposits.

To explain the difference graphically, the grades of a typical Aussie gold mine plot on a graph like the top left chart with a +ve skewed distribution with an average grade of 2-5g/t. The grades at the high grade tail of the chart get top cut so they don’t have too great an effect on the average grade.

At Tres-Ema, the grades are going to have a much tighter distribution much more like the bottom right histogram with an average of say 60g/t Au and there will be little or no need to apply a topcut because the high grades are more typical and won’t have an effect on the avg grade.

That means that the grades of the bulk sampling can be believed and although there will be some zonation of the grades it is very likely that we will get similar grades from the drilling.
