Whether you are placer or hard rock gold mining, maximizing the efficiency of your recovery process is very important to success, and accurate testing is necessary to do so.
After paying for the mine fleet, mill capital, supplies, fuel, power and labor, at today’s metal prices, does this mine make a profit?
With the recent surge of interest in gold projects, it’s about time to revisit a subject that strikes fear into the hearts of small-scale miners: Permits.
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
Fortunately, there are products on the market that can address these problems and make a small-scale mining operation feasible.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.
How big is the deposit? Are there boulders you will need to move? Do you just want to recover the nuggets or do you think there is good fine gold that you will also want to capture?
When detecting an area that has been cleaned to bedrock and you have new trees growing, always make sure you get your coil as close as possible to the tree. Why?
For simplicity, I will assume that you wish to make enough profit so that you can comfortably pay your bills using just the profits from the mine.
Mining claimants who wish to retain their mining claims on Bureau of Land Management and Forest Service lands through the 2021 assessment year must pay a maintenance fee or file a maintenance fee waiver certificate on or before September 1…
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
…the process remains much the same: Drill holes, load explosives, close up the holes, blast and muck out the resulting broken rock.
Micro blasting can be used to take down hanging rock, separate minerals from overburden, and collect gemstones and other high-value product with minimal damage.
