Mining for Gold and Sapphires in Montana
April 2014 by Chris Ralph
Fascinated by the sapphires—and the gold that occured with them—he was soon buying parcels of property and setting up his own commercial-scale gravel processing plants.
Pumping Water With Solar Power
Solar energy can be used for any size placer or hard rock mining operation. It is most practical for small and longer-term operations provided your mine is not located in a dense forest.
Practical Advice for Milling Hard Rock Ores
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
Gold Rush in the Congo
It all started with a phone call from my friend and prospecting partner Pat Keene. He told me that he knew of an investor who was just starting out in the gold industry and was looking for a gold consultant to go to Africa to prospect and analyze a 400 sq. mile concession in the middle of the Congo rainforest.

Ancestral Yuba River Placer Gold Deposits
The small-scale miner has reasonable opportunity to exploit some of these small, rich placer gold deposits.
