And the Australian Explorer of the Year Award goes to...., page-6

You could also look at the announcements by RMS on their Penny deposit , there is a DFS on that deposit announced by RMS to the ASX a few years back , I also looked at the Challenger deposit in South Australia , that KCN use to have to see potential depth , (although that deposit was formed differently from NN ) think it went down well over 2 km .
I got into challenger mine when Dominion had it over 20 years ago , did ok , Peter Alexander was there then , he went on as a director of Doray and think he is still with KCN , met him a couple of times , tough hard old guy .
Great Fingal that WGX have is also comparable , although a bit anaemic compared to NN in intercept width and grade IMHO .
