There is an interesting article posted on the stockhouse forum titled "Researching Gold/silver Mining Companies, authored by Jeff Nielson on 9/18/2010.

It has some important noteworthy information including how to calculate the value of resources in the ground. Importantly, for PEM shareholders who surmised that the latest drill results were less than stellar, just the opposite is likely true. Under the sub-title Resource Size/Drill Results:

". . . . . . The drills cut vertically through these layers and when they encounter mineralization, these layers are refered to as 'intercepts' . . . . . . which include depth. . . width. . . and the concentration. . . . It will likely astonish novice investors to learn that most ore containing as little as 1 or 2 grams per ton of gols can now be mined profitably. As gold prices continue to soar higher. . . 1/2 gram per ton of gold will llikely be profitable. . . . . . . . While many investors' attention will be focused solely on the 'headline numbers' with repsect to purity or 'grade' of the ore, such temptations must be suppressed. Yes, the grades are very important, but what is arguably even more important are the quantity of such intercepts - and their width. A half dozen wide intercepts of 'low grade' ore will yield 'FAR' greater resource than a thin single vein of gold - no matter how rich the grades are. . . . . . ."

The Friday-Petsite, alone, is a gold mine operation waiting to happen. At a mining process of 100,000 ounces a year, a mining operation at this location could last a couple of decades (+or-).
