is this the most overpriced stock on the asx, page-67

I know you will call me a downramper but please get informed.
Tungsten APT as quoted on the Primary Metals Website is for Ammonium Paratungstate or APT,. This is trading in the region of US$240 - 250 / mtu.
This is NOT the price traded for Tungsten concentrates. That is more like US $195 - 200/ mtu. ( Check the Metal Pages websites).
To make APT from Tungsten ( Scheelite or Wolframite ) is a complex process. It is unlikely that any Oz producer of concentrate will add a APT plant to its plant.
