Resurrecting An Old Hard Rock Mine—Gold At Last!
May 2019 by Ron Kliewer
We’ve been busy with a plethora of projects, all aimed at gathering gold into a pile big enough to brag about. We’re not there yet, but I’ll show you some of the interesting projects we’ve completed since we talked last.
Underwater Reclamation
Working underwater certainly has its challenges, but since I wanted to learn how to blast underwater, I just needed to dive in headfirst and take charge of the operation.
Wealth Beyond Your Wildest Imagination
“Wealth beyond your wildest imagination.” Those were the words that were used to inform me of how much gold was in a paleo channel that exists beneath the present channel of the Similkameen River in the State of Washington; words that have echoed in my mind for the past sixteen years.
Principles of Designing Your Mill Production System, Part II: Mill Design
Starting small with quick profitability gives you a lot of financial elbow room plus real-world experience that can be used for final mill design.
Gold in Quartz
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
Ophir—Possibly the Best Kept Secret in Alaska!
...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.
