I'm not exactly sure where they are getting the ore but I'd assume it's any of the high grade hits drilled above the adit and let gravity do the work. Grades they get will perhaps largely depend on how well they sort the ore. I get the feeling this could be getting towards last roll of the dice, hopefully they get some high grade profitable oz' asap.
"Pay some bills", I reckon they'd have a few of those building up. Results could be anytime as they seem to be on a bit of a mission to get RoD happening asap.
