Ann: RIU Explorers Conference Presentation, page-60

I'm new to BC8, but i like the straightforward strategy towards good cashflow in a relatively short time horizon. I remember being impressed with Les Davis taking this approach with Silverlake many years ago, whereas other companies tended to drill forever with copious cash raises and dilutions.
My only question at the moment is this: Are the 250k ounces viable in an open pit situation, with normal strip ratios, or does the pay dirt require a high strip-ratio to be accessed? I realise the feasibility is still in progress, but to those who can read between the lines, does what we know thus far suggest we can pretty much get 3.4 g/t average from the get go? Or is a "narrow-vein" system more complex than this?
