"It probably means a quadrupling of the original Eagle 1 resource,"

Firstly the word "original" wasn't used. Secondly why would one refer to a previous defunct number to benchmark against? It may be of record but it no longer serves to keep relating to it as some sort of benchmark. Just my thinking, but it will be clarified soon enough. Given what levels they are drilling to and the new explorations it would seem unlikely to only be coming up with a total of 15m.
