I have a gold and platinum mine in California USA. I would like a list
of labs that I can send my ore (rocks) samples off to be analized, for
there gold and Platinum content. If posible I would also like a list of mining
companys that purchase gold and platinum mines for when I choose to
sell my clames.

Try going to:

and doing a company/property/supplier search for analysis.

This web site is full of resources for someone in your position.

Rare Metals Corporation in California is one such company:
