RE: I found this - calculation => 100 % up sideof the cash flow potential on my paper :
Silver : 4.3 million oz/year x (14-4.5)USD/oz = USD 40.85 million per year.
Assuming 208 million fully diluted shares you get cash flow of CAD 0.22 per share, just for the silver.
Copper, 3.1 million pounds and lead, 23 million pounds add credits of some USD 32.5 million or CAD 0.15/share.
If we use a cash flow multiple of 7 on the silver related cash flow you get CAD 1.54 and add the base metal credits at a 5 multiple, CAD 0.75 you get a possible valuation of around CAD 2.30.
So the USA might double if this cash flow potential is fulfilled within a year.
