Ann: Progress Report - Results of Mt Boppy extension drilling, page-13

Yep and if you look at those old shafts even they went that deep because they were still getting results (for the time). The old timers missed a lot above that and will have missed even more below that as it becomes way more difficult the deeper you go. Modern machinery in an open pit mine can just remove so much stuff, it is like comparing a needle scratching out a hole compared to a shovel.

There are also other shafts nearby to the south, south west, which likely indicates even more untouched stuff to that direction. But a whole lot of dirt to remove to get there. As much as these drill results are good and will mean MKR move there if silver price hasn't moved. I am more interested in the silver results at Wonawinta, that deep stuff will expand the silver resource greatly IMO.
