According to the 2009/10 financial reports, PRMO has 6100 kg of gold bearing material in inventory. Management has decided to wait till higher gold price. It seems that this is the time which gold index is at ~$1380. So, I did a simple calculation assuming that if PRMO sell all inventory today, the present value (net profit) of the 6100 kg gold would be $207.4 million based on $1380.
