Thanks Herb for that post - obvious question now is.....
Given the nuggety effect and that drills dont convey the grade with any degree of accuracy beyond +/- 100%, why use bulk sampling across the vein to calculate grade when it is known that the sample will include all the material trenched, i.e. non-quartz and 'earth'. Why not just take bulk samples along strike. The grade so established will better represent the true grade and therefore give a better indication of tonnage. Wont it?
