FFF, you have probably made the mistake of thinking that royalty check was for copper, not magnetite. You use 18 cents a pound. Your arithmetic is okay but that price is more like magnetite than copper. ($360 per ton (18 cents/lb) for magnetite sounds high, however.)
We know CPRK has been refining magnetite for a long time now, since well before the time limit for reaching production. This is my view as I recall seeing that magnetic separation equipment make that pile of black magnetite many months ago.
IMO, MD has used the magnetite production to satisfy the PN contract. People should also not assume that one has to sell what is produced. That it be produced is satisfaction (of the contract) enough. Right? Magnetite has been sold. Copper con has not been sold. No problem!
That last Fact Sheet lists the active mines and also states that the magnetite was "removed, washed, processed and shipped..." as well as the contract for magnetite that was signed in August 2008.
Like many of us, we each have our own view of the history of the company. This is mine with respect to this current legal move.
Also, just because PN asks for information doesn't make it part of the contract, does it? Let them eat cake!
