Prospecting & Detecting
Chasing Hard Rock Gold As A Placer Deposit
August 2021 by Don Robinson
The question I had, and likely you have too, is when an old channel is cut, how far does the placer gold in the cut channel move down in a river or creek that continues to erode deeper and deeper?
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.
Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
River Dredging vs. Creek Dredging—Part I
As I started walking down to the river one chilly morning, the mist was hanging over the calm portions of the water like a white cotton blanket. This scene got me to thinking about why the river was like that—the deep pools, boulder fields, gravel bars, the effects of how much water was moving at any given time along the watercourse—and most of all the relationship all these things have on where I will be able to find gold.
Ganes Creek After The Flood
Doug told me that there had been a 100-year flood that took place in October of 2013 and it washed out part of the mile-long landing strip. It also washed a large, wide gully down below and above the camp.
My Lucky Month of March
My wife Maureen and I spend part of our winter season in the Quartzsite, Arizona area. One fine March morning, we left our RV camping area at approximately 10am in search of that elusive yellow metal with our metal detectors.
Twenty Minutes on a Five-inch Dredge
The first thing I realized was this was not a toy—this thing had power and I needed to really pay attention. I got into position, took a deep breath, and pushed that monster into the hard pack.
The Gold Of Horseshoe Bend
And we eventually reached gold. It was a winding crevice of beautiful white quartz lined with small nuggets and loaded with fine gold. There were flakes and small granular pieces—there had to be a hundred or more.
