"Gold Rush: Alaska" in the Porcupine Mining District
June 2011 by Jim Halloran
Honestly, I don’t believe it is likely there would be a glory hole where they described one at the bottom of the waterfall because plunging water with enough energy to scour out a large hole in bedrock would have the scouring ability to grind up and...

All the Gold Ever Mined...
February 2012
If you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”

Researching Mineralized Areas
December 2015
There are a load of ways to do research, and I’m going to talk about how I do it—maybe you’ll get some ideas that will work for you, too.

The Basics of Geophysical Exploration
February 2012
In developing a mineral property or mining claims, one of the first goals is to identify and quantify valuable deposits. The classic method of doing this is by drilling holes into the ground to sample what is below the surface. The problem is that one or two holes usually are not going to tell you a whole lot...

Heavy Sands Mining
February 2013
Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.

Rock and Formations of the Mother Lode Gold Belt
October 2015
The faulting, folding and shearing that occurred in the Mother Lode belt has created zones of structurally weak rocks or contacts between different types of rock, which has been favorable for the deposition of gold bearing ores.
