Prospecting & Detecting
Highbanking for Gold
August 2018 by Chris Ralph
Pumps can be set up quite a distance away horizontally from the sluice, even hundreds of feet. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30 to 40 feet is the maximum vertical climb for most pumps.
Fall Drywashing—Just the Right Time of Year
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
Mining for Gemstones and Mineral Specimens
It is better in a gem and mineral mining operation that the driller, blaster and mucker be the same person in order to be able to predict placement of the desired mineral enriched pockets.
Continuing Hard Rock Exploration
We had been picking away at it, but the going was mightly slow. Why not use some explosives to advance a little quicker?
Understanding Skim Bar Placers
Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
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.
Keep Watch for The Unexpected
As I have always done, I stashed those heavy black rocks in my pack and put them in the garden at home. They never were given a second thought until a half decade later…
Carr Fire Gold
After burning more than 350 square miles, the Carr Fire near Redding, California, was finally out. Luckily our home was spared, and I had the opportunity to go metal detecting in burned areas previously too overgrown to access.
