Hi Unwired!
Yes, I think they have taken the original resource and then proven up a much wider deposit that can form the resource for a bigger mine around the old workings. Again, my expectation is that a buyer will find the pit dimensions to be attractive based on the drill results that are coming in. The absolute grades of that peripheral material are not a big deal, its the fact that these zones can be included within the resource envelope to be mined at a profit that matters, instead of adding to the cap-ex of waste rock that must be stripped off before a big mine can commence production.
cheers!
