Confluence: I appreciate your comments. From a statistical point of view the variance (difference) between the first 2 pits meant that the much larger sample size was required to determine what was in fact the actual consistant value of the ore. The next results, being from a much larger sample size, will display results closer to the average. I'm sure they would like to see consistancy between the two 3,000 tonne samples. And I'm sure the two 3,000 tonne samples will be more similar to each other than the two smaller samples were to each other. Statisticaly the larger the sample size, the more similar they become. It would be a gross error to extrapolate the 3,000 tonne values from the smaller Pit 1 and 2 values, rather the smaller samples should be evaluated to see whether it is possible that they came from the larger sample.
