The Sinker Tunnel Complex (L530) near Silver City, Idaho summary from 2011:
$9-$37 million/year net income (not sales) x 15 years (that was lower gold prices) = $135 million to $555 million in net income and DSCR is getting 50%! Hello
If the weight of ore remaining to be mined amounts to 1/3 of the original lode deposit (which is thought to be grossly underrated), a net present value of $141,210,472 is obtained for a fifteen year average total annual pro forma income stream before taxes of $9,414,032.
If the weight of ore remaining to be mined amounts to 1/2 of the original lode deposit (a more favorable and hence less likely result), an only slightly less arbitrary discount rate of 15% is used and a net present value of $282,420,945 is obtained for a fifteen year average annual pro forma income stream before taxes of $18,828,063.
In the most favorable and least likely event that 2/3 of the original ore remains for our mine, a discount of 18% is used, for no justifiable reason, and a net present value of $564,832,020 is obtained for a fifteen year average annual pro forma income stream before taxes of $37,655,468.
Estimated annual production of ore varies between the three scenarios in anticipation that a smaller mill would be used for smaller reserves available during the term of the lease. Larger mill facilities could shorten the time taken to mine and process discovered ore reserves and would, consequently, improvethe net present value of the income stream.
