Ask The Experts - Is this gold?
September 2017 by Chris Ralph
Q: Can you tell us what the indicator rocks are? I’ve looked at the nearby digs and pushes that were made for gold and it looks like we’re digging on some similar material...
Any good books on mineralized faults and contacts?
Q: I would like to know how to use a classifier when I dump my gravel into my sluice box. I would also like to know what sizes classifiers come in. I know that they are in sizes like -3/4. What does the “minus” in the size mean? Thanks for any help you can give me.
