Real wealth/value is knowledge not $s. 
In most of the PR's PYR releases there is some reference to what they have/will discover. In the powder PR they mention discoverry of new refinements while setting up the process that makes it even better. HPQ is consistently paying PYR to do research. The tunneling PR basically says the same and Peter mentions in executing it PYR discovered new potential opportunities in this area. The Q4 release says they received tax breaks for research they have been paid to do.

The best part is we only see a small % of what is being discovered. It is this knowledge and know how that has put PYR at the forefront and it is what will keep it ther.
