I found the link below to be an excellent comparison to our Tesoro in terms of cost/grade/tonnage ratio. Keep in mind the year was 1998, prices of cost have increased, but the ratio,s have not. The POG ratio to the costs, which I haven,t done, has probably outweighed the rise in costs. Nevertheless, this deposit of Barricks resembles our geology almost to a T, except, I beleive our grades will be higher, as there is evidence of that when comparison of Arequipa,s grades to our own, shows us having a higher average, with what I have to work with at present.

Remember the resource, PIERINA, belonged to Arequipa Resources that was taken out for around $40 a share, by Barrick. This deposit made Catherine Macloed Seltzer famous, a partner in Arequipa Resources, and their sp ran wild for a couple of months. Barrick bought Arequipa,s deposit out on the assumption that part of it (Pay Back Hill)had an average grade of 8 g/t, when they actually mined it, the grade was 3 times higher, at 24 g/t or so.

Below is a good read on Barrick. Take note of the aquisitions and amounts paid for them over the years.
