Q: How do I improve my small-scale mining operation’s gold production?
This stringer was where it was not supposed to be, and it contained nuggets that were not supposed to be there.
The holes were overloaded with explosives, but I didn’t know it. I was just a green mining engineer fresh out of school and told to watch as the experienced miners set the charge.
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
In an old mine that does not have stopes, you know the old miners did not take much if any ore out of that excavation. On the other hand, if you see large stopes within the mine you know that it is these places where the miners found profitable ore deposits within the vein.
Within the first 3 hours he and I had found pocket after pocket of gold and couldn't wait to tell Levi of our treasure.
