Thanks ecker, I get it now, so we just multiply every column and in the end convert grams to troy oz. So if we extrapolate and assume we have the same ore quality for the length of the strike (1500m), we'll get closer to 880,440 oz.

I can see how we get the length, depth, width and grade figures from the reports. But how did you get the Specific Gravity of quartz figure?
