Hey Mr. James,
You can learn more about Penoles off of their website. Here is a direct link:
http://www.penoles.com.mx/penoles/ingles/index.php
Penoles trading symbol is BMV: PE&OLES and they trade on the Mexican Stock Exchange.
Penoles is the largest Silver producer in the world. They had a record net sales of over 4 billion dollars in 2007.
They were up about 3% today.
Maybe it is because word of their Peru project is leaking out ;^)
