resource estimate after upgrade

While reading a lot of literature here and there about the coming resource upgrade, I tend to be more conservative on all figures mentioned on HC.

Firstly, I ran into this announcement from Madison minerals, reporting the effective resource back in 2007.

Based on this announcement, they used a US$550/oz gold price and a silver price of US$10 for their estimates, which is not really what IDC stated on their announcement (US$300 and US$5.50).

Am I missing something?

Then, the "automatic upgrade" on lowering cut-off grade and swapping to the Australian JORC code might not really give a resource of 4-6Moz as stated here and there. Based on the following post, I would be more conservative:

Therefore, I'm rather expecting a JORC estimate of 3-4Moz.

What's everyone thinking about the coming JORC??
Any thoughts?
