Mining for Gemstones and Mineral Specimens
August 2013 by Jim ClaninIt 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.
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
So, I took the plunge. I decided on the maximum I would pay for the claim, then placed my bid. A day later I received a congratulations e-mail that I was the high bidder, and oh, by the way, send us your money.
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.
Breaking cemented gravels
Prospectors have many reasons why they might want to break rocks. These include dividing up a specimen too large to carry.
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.
