I will get back to you in more detail later. The galena and couer mines actually produces at a lower cash costs than the sunshine in the 1990's and early 2000's. I did read the 43-101 briefly. My question is how much annual production would be from the chester? Based on the percentage of reserves it would look to be about 1.5 million ounces out of 8 million projected. The report also indicates 11 dollar total cost. What would be a good approximation of the nsr or 20% net profits interest at $25 per ounce silver? Production would be at least 27 years or perhaps longer since the chester is perhaps "open at depth" ? Thanks for the reply!
