Ann: RIU Explorers Conference Presentation, page-21

@salpetie All good points well received. You nailed it with this quote "Churchill is quoted as saying an hours speech takes 5 minutes but a 5 minute speech takes hours. To condense the above would take a lot of work."... exactly why my posts are long and wordy also, just type what comes out and hit send. No apologies necessary, and how long to read a long post anyway, a few minutes

The 43km of ironstone is absolutely critical, nothing less unless a stunning orebody is discovered inside the carbonatites. That they are in-fill drilling YIN and prioritising the carbonatite targets speaks volumes for where they see fastest and potentially biggest bang for their buck. Spending a couple of months testing the ironstone upside along strike, while potentially disappointing C1-5 assays dribble in is poor tactics unless you are confident the ironstones will deliver. That was my point. Better to infill almost certain good Yin numbers to keep headlining releases, while hopefully hitting the motherlode carbonatite that makes whatever ironstones have to offer a mute point.

Regards extrapolating Yin high-grade/thickness into 43km of ET, one issue is what you may call 'nugget effect'. Very high grades in nuggety gold deposits for example need a top-cut (eg 250g/t cut down to 50g/t) because resource geos can prove statistically extrapolating highest samples will skew the resource unrealistically. Drilling 1m @ 250g/t is does equate to drilling 250m @ 1g/t, even though mathematically both intersections contain he same Oz gold. 250 individual metres @ 1g/t Au is statistically and geologically very robust, 1m @ 250g/t probably reflects only a small area of influence.

Before you say Yin is a deposit not point sample, the other problem with extrapolating the districts largest HG deposits is 'sampling bias'. Yin was drilled first, the only DRE MRE because it stood out as the best ironstone target for a large, HG deposit. The Mangaroon ironstone sample set is woefully bias at this early stage. Yangibana extensive drilling is a far mor valid sample set of the projects ironstone fertility. Even then, there's clear sample bias because HAS focussed on the thickest, highest grade ironstone outcrops and chasing the best ironstone holes along strike. Yangi's tonnes/km average for all 66km would (will) be lower than it stands today as measured only over the deposits drilled out to MRE status (which is what HAS did).

All very boring and without familiarity with resource geology, none of this would occur to anybody. ET's like these are released for the masses, not industry types obviously. This is an example of why I usually see things differently, I simply don;t have a choice.
