Ore Grade Questions
I am having trouble understanding the rare earth ore grade. From the Stockhouse News list, the May 28th article there is a graph of ore grades of various mines. Notables are Bokan at .8%, Mountain Pass at 7%, and Auxico Colombia at 57%. Now, yesterday Sept 21 there is a new article with additional results. The new samples are coming out today from Area 50 is 2.5 kilograms of concentrate taken from 3 tones of raw ore. 2.5 kg is 5.5 lbs. Only about 60% of this is TREO which is 3.3 lbs. 3 tonnes is or are 6000 lbs. 3.3/6000 gives a raw ore grade of only .055%. The article titles imply that the Colombia discovery is far richer than Mountain Pass. I hope so, I am a shareholder. But the new information indicates a raw ore grade worse than The Bokan project. What am I missing?
