How To
Using Geologic Maps
December 2015 by Chris Ralph
In order to see what geologic maps can do, we need to think about what we are looking for.
Determining The Optimal Crushing Size for Gravity Recovery
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Detecting Alone -- What to Look For
I figure there are a lot of new people out there who have the same question. I will try to give some answers that hopefully will give you more confidence in finding your own spots.
Breaking Rock the Old School Way
Prospectors have many reasons why they might want to break rocks. These include dividing up a specimen too large to carry.
Sampling for Success—Part II
The first and most important thing of the sampling process is to try to be as unbiased as possible. There is a natural tendency to select rock that looks the best—even unconsciously.
Ask The Experts
• Two questions: Is fool's gold magnetic? And how do you go about filing a miing claim?
What Have You Got to Lose?
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?
Volume is the Key to Success
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.
