Hi Stock Girl,
Thanks for the reply. I got my numbers from the ibox. It's from the Google books screen grab about a quarter of the way down. The book is the Annual Report of the Ontario Dept of Mines, and it's the paragraph labeled Queen Alexandra.
Cannon's web site says "an English mining syndicate sank an 85 foot shaft and milled 18 tons of ore, grading 16.6 ounces of gold." That would be 16.6 oz/t. I don't know how that reconciles with the historical report in the ibox, which mentions "18 tons of the ore treated, producing $16.00 per ton in gold." (Back then grades were typically reported in $/ton, not oz/t.) That would imply 16.6 oz = $16.00, or 96 cents per ounce of gold. The price of gold at that time was about $20/oz. $20/oz would imply a grade of 0.8 oz/t, which is more reasonable, and typical of those times, but low. It would have been low enough that mining it would have been economically marginal, which may be why mining was not continued. Grades like that are economical today, though. I think Cannon has made a serious fundamental mistake in their calculations. The grade was 0.8 oz/t, not 16.6 oz/t. And the 18 tons of ore at 1.6 oz/t yields a total of about 29 oz of gold.
Drill holes may be square, but they aren't inherently "cube-shaped". Veins of the type mined back then were typically fairly rich (1-2 oz/t or so and up), but narrow, and certainly not 85 x 85 x 85.
