AZS Secures funding to advance Mexican Silver Discovery, page-63

How longs a piece of string question really.
Should a JV be formed..would mean that likelihood of Porphory being present is high hence then the question that remains to be asked is how big ? and of course..how economical?
Have a look at chart of typical sized Porphory per attached link which I have provided previously..Take a stab at a mid sized deposit and then crunch the numbers..based on typical Cu @ 0.3% then that should give you an answer. All thumbsuck  but at least theres a good representation of typical sizes associated with Porphorys to get an idea of scale.
Somewhat interesting to say the least..
But before we jump the gun..lots of work to be done beforehand and big $'s needed hence the JV with RIO/ Kennacott being a good match for sure.. however the numbers really do give an indication of potential.
