One of the issues that prospectors run into when working to upscale from micro-scale hard rock testing to a greater production output, is that they often confuse individual devices or machines with systems.
…as an academic argument, when mated to the appropriate engine, is the pump really moving water at the rate of 400 GPM?
I pulled out the nuggets I had worked on previously and looked at the size of the wire basket that the items to be cleaned are placed into. It looks much like a miniature french fry deep fryer.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
