Prospecting & Detecting
Hard Rock Milling: A Matter of Scale
April 2013 by Chris Ralph
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
Eolian Placer Gold
I would first like to mention that I am not a geologist. I have, however, spent the last 8 years intently searching for gold nuggets with a metal detector. I have found gold in numerous locations, and in several different types of gold deposits.
Swing and a Miss
A very good baseball hitter might get a hit roughly one time out of every three at-bats, but for prospectors often the results are much sparser and it may take many trips before the prospector hits a home run.
Persistence Leads to Over a Pound of Gold
I have figured out over the years that the winning combination is hard work, persistence, knowledge, and a little luck. This leads me to describe one of my best finds ever, a “honey hole” of placer gold, if you will.
Sold: 87-Ounce Nugget
A gold prospector in central Victoria, Australia stumbled across an 87-ounce gold nugget in early February 2015, after his wife told him to head outside to get some air. He had given up smoking a few weeks prior and was getting a bit “grumpy,” she told him.
An Alaskan in the Lower 48
Our destination was some old hydraulic workings where the old miners had washed literally mountains of material away to expose gold in ancient river channels.
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.
Small-Scale Miners Rock the Mining World
With the high price of gold, there are many new prospectors out in the hills all over the United States, and while we would all prefer to be finding those larger nuggets, it doesn’t always work that way. Sometimes all that is available is nothing more than a few small flakes. The truth is, new prospectors are sprouting up all across the planet—especially in the developing nations.
