what's it worth?
that includes a lot of other questions - a partial list
how good is the ore
how much of it is there
what will it cost to mine (capex and ongoing operations)
dito to process
what price can we get for the product (probably a concentrate or concentrates)
taxes?
other?
at this point, we're just working on the first two parts of this. it looks good, but there is a long road ahead.
