Well at least you know the highest grade you can attain. 1792 grams. The lowest is zero. The average? Well just divide by two. Isn't that what they do? I would think they could get continuity for at least 37 and half inches, maybe more. If they drill another 100 holes they should come up with maybe one, or two more holes like that. they will also come up with no significant values more than once or twice. Gold mining is fun. One way of establishing grade is two throw all the sections down a set of stairs labeled with the grades from highest to lowest stair. Gather up all the sections and assign appropriate numbers. Multiply by the age of the geologist, and divide by the number of times the property has been held by various mining companies. Report in pennyweights. Works in most areas. I like to average arithmetically all the assays in what you would estimate you might mine, regardless of length of intersection, if assay selection is done by another geo. He usually sets out to assay a section that he finds geologically interesting. You ignore width when averaging. This will be by 100 years experience, if you don't use any other factors such as cut backs, most probably what you will mine. At the Dome for 90 years they mined at one set of assays, with about 600 samples underground of all kinds ... and milled double that. Their nugget factor was 2. Average recovered grade was 0.25 and average head grade from sampling was 0.12 OPT. There has never been established at all mines any efficacy to averaging grade times width. It is very misleading and is only operative some of the time at some deposits. EC<:-}
