well guess what

Always pays to do a little due diligence.

here is a clipping from 1936. Looks like the old timers well and truly picked the eyes out of this one.They left anything under 12gpt . Wonder if they took that into account in the inferred resource. Those mighty head grades were in fact a result of taking only the cream out of the reef.

Crikey! How do you model that in a JORC?

First you have to estimate the width, then you need to know how much quartz reef they left behind because the dolly pot guy said "dont take it up boys it aint worth milling"

a tricky business this JORC estimation.

There is another old 1930's clipping I saw a while back, I'll dig it up and post for a good laugh.
