Looks like this thread has been taken hostage by MCO rampers. Personally feel SLR has better ground plus have their own mill . All this grade factoring talk seems spurious without their trial mining proceeding how hard is it to get out a portable air leg and way off a few chunks ?
When I was a boy back in 1929 we didnt muck around with all this trial mining stuff we just got out a pick axe and mined the darn stope for all it was worth then sold it to to the Feds.
