why the selling

I thought the PFS ann was fairly conservative and well thought out. Its based on a gold price of US$400 an ounce and copper price of US$1.15/lb which is very conservative based on todays prices.
Now the first gold pour is only days away.
Who knows were the gold and copper prices will be in March when the FEB is to be completed. The predictions are that gold and copper will be higher next year. Also by taking a conservative and measured approach to FEB there appears to be considerable savings in the start up costs. Lets face it the gold and copper isnt going anywhere while its still in the ground so any gold and copper price increases in the meantime is a bonus.
Meanwhile PNA is producing gold to help pay for the start up costs.
