RE:RE:Estimated Tonnes and GradeYou're both part right.....long342 the only issue I have with your calculation is this:
First, you're not going to mine from surface, for 2 reasons:
1) strip ratio would be too high - the mineralization is in a valley, so you're going to have to start cutting down the mountain on either side to mine it, which adds to the strip, which will make mining uneconomic; and
2) The first, say 300m of mineralization is too low grade....remember hole 62 from last year? The first ~ 300m averages less than 0.2g/t Au and 0.2% Cu.... that's below cut-off grade, therefore uneconomic.
Also, you need to factor in that the reported width is not true width, so apply whatever factor you want, but it's likely something less than 100%
As far as depth, it looks like they've only drilled 700-800m vertically (the hole was drilled at a 60 degree angle, and it was 920m down hole).
And, along strike, they've only drilled about 400m....
But, you are correct in saying that the "Potential" is 1,000m along strike, given the IP anomaly, and beyond 1,000m at depth potential..... But can only prove with more drilling, which costs $$$ (and dilution to shareholders).
Just my thoughts.
