Q: Could you write more about the last two methods that you mentioned—the expanding chemical mixtures and the micro blasters, how and when to use them, and when not to use them?

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?
