Ann: Aurora Tank drilling yields new high-grade gold extensions, page-33

Read what I said.
From my interpretation of the announcements and the idea they are pushing has been centered around mining the top 60-70m via a heap leach operation. Apart from a few diamond drill holes very little has been confirmed about how thw area below 70m can be processed. It is possible that the rock gets harder ( we do know that from the bench pit wall design) and may not be economical or practical to use a heap leach process. I would naively assume that downing tools to change processes after mining has commenced would be hugely expensive. Which is why I'm asking the question will the heap leach process be good enough once we mine the top 70m which really would not take that long if we have a big enough resource.

I would assume management should have done some preliminary testing in this regard, but I haven't seen that info released.
