Ask The Experts—What's the cheapest way to mine quartz for gold?

August 2011
Q: I have a gold mine in Colorado. There was an assay done which stated [there is] a lot of quartz within the mine. What is the cheapest way to mine it for gold? I don’t have the money for mills, etc. Can I do it by hand (during summer holidays), and how would I get started?
