It's all speculation on our parts but I would go by this statement from the most recent news release which referrences an old article.
Extensive interviews with the Ruby mine manager, Lewis Huelsdonk, make it very clear that if it was up to them, they would never have stopped mining, and that the best days of the Ruby are still in front of it. The article states, "And if the war had not interrupted their mining operation, who knows how much gold Huelsdonk and Best could have extracted from the Ruby mine. 'It seemed like we no sooner got onto the gold when the war broke out and the government closed the mine,' Huelsdonk laments. 'We were right in the middle of taking these nuggets, so you can imagine how we felt at the time.'
So, I'm guessing they're not wasting time with the little stuff. Rather, Perry's going for the mother lode. Remember, any fool can grab a shovel just start digging but we're investing in experts who're here for success.
