I remember you mentioning a (preliminary) scoping study done on a project that was never pursued is that what you're talking about ?
If not , don't recall !
OPEX is dependant anyway on the details of a particular mine so anything you or I could come up with for OPEX is purely guesswork but we need to put some figure on it to judge how quickly the CAP EX can be repaid .
So rather than destructively smacking me down why don't you revise your figures ...estimating an OPEX , estimating CAP EX and make sure you're basing calcs on sale price of Zn concentrate not Zn metal and we can try and judge the viability of the project .
We are both holders , both want what's best for the company ...I'm genuinely interested to see if you can come up with something to prove me wrong .
I'll keep an open mind and if facts prove me wrong I'll admit it !
However at present looks pretty clear to me that its small AND marginal despite the grade .
Heartened by what you wrote about being approached by mills .
I don't always read everything here !
