This assay system of ounces per ton sounds simple enough, but the use of the metric system and the additional measuring terms of “grams per ton” and “parts per million” (ppm) has created some misunderstanding of ore value.
I regularly get inquiries along the line of: “Hey, I found this rock, and I think it might be gold ore. How can I tell?” Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.
Once you have determined that the land is locatable, the next step in the claim research process is to determine if the land has already been claimed by a previous locator.
While recovery rates are important, they must necessarily be secondary to the volume of material processed. Running more material at lower recovery rates is generally preferable to increasing the efficiency of the system.
Once you get down to the black sands or a few tablespoons of material, the technique changes dramatically.
Many specimens have a small amount of gold and are not pretty to look at. There is a nifty way to give them a makeover and make them much prettier than they were when you found them.
I will make the assumption that when any of you take a detector in your hand and head out prospecting for gold you are probably anticipating finding some gold. That’s the general idea, right?
Choosing the right method to move your ore and waste is all about making the right choices. Sometimes more than one method may be used during the life of a mine as an operation expands and grows.
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
These three simple upgrades, when taken together, will considerably increase a pocket plunger’s magnetic pull and make it less susceptible to breakage.
Q: I am in the process of filing an appeal with my lawyer, but am seeking more “expert” advice in the arenas of “mining claims” and BLM jurisdiction.
The anticipation of finding out if the system of snatch blocks, shackles, chokers, anchor points, and the strap binding the massive slab of rock in the bottom of the river would even budge an inch was weighing on me.
Q: Aside from the softness scratch test and other methods of identification, what feedback would you have on identifying gold in hard rock that may be mixed with other metals that affect its color?
Q: With safety as a given, what can the average miner, or Joe-blow greenhorn do to identify and extract some metals or minerals with off-the-shelf products or natural ingredients?
