Ann: Initial High-Grade, Independent Resource Over 3kms at Yin, page-64

@salpetie

Good post, as usual mate.

I too am surprised by the density figures. This is why I suspect the estimator wants more density data prior to classifying anything as indicated. I think its legit, but perhaps its just a little too uncomfortable without a little more data to prove first?

I used 2.5 in my estimate at 13mt. I just like to be conservative with density as it has such a massive impact on tonnage. Way too easy to over-estimate tonnage at this stage with a generous density value. A while back I quickly skimmed through HAS announcements to see what densities they were measuring, and they had wildly varying densities. Some very low around 2 and some very high up to 3.5ish. iirc. This is not surprising in rocks with high carbonate content, as weathering can create a lot of voids and cavities, greatly reducing the density (but this can potentially result in higher grades...)

I agree with you. Tranche 2 is a near certainty for 2023 (in fact I think they will get it from Yin alone with just a bit more drilling to the north), and I agree tranche 3 is probably more likely than not as well - depending on how the carbonates look and if they will get an estimate out for them.
