If you look at the NI43-101 reports posted on sedar, both the 06/19/07 report posted under Sterling,and the 12/27/2012 under Sunshine Silver, they both make the same comment- the Sunshine consistently converted to resources to reserves for over 100 years.Being an underground mine, usually due to cost involved mine would only target developing 5 to 7 years reserves at any one time. Note that Sunshine Silver continued using Stelring's exploration plans, and apparently has increased the resources another 25 million ounces. <br /> <br /> Sunshine Silver projected a life of mine cost of $14 an ounce ( higher than Sterling's). I note specifically for Chester vein area high grade silver, 22 to 32 oz silver per ton. <br /> <br /> As far as Hecla Mining's decision to sell Consil remember the 90's had low silver prcies, and Hecla was battling EPA to survive at that time. <br /> <br /> I note some former Sterling employees with sub penny start up First Colombia Gold.
