Quartz: The Indicator of Gold
Prospecting for Copper—What to Look for on the Outcrop
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
Heavy Sands Mining
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.
All About Garnets
I get a lot of questions from prospectors about garnets, their value and what they tell us about the geology of some types of mineral deposits. So I thought it would be a good idea to take a closer look at the lowly garnet and learn a bit more about it.
Gold and Rare Earth Elements in New Mexico
We import nearly all of our REEs from China, so it’s critical that we find and continue to develop domestic resources of these elements.
All About Native Silver
Some of the wire forms are strange and fantastic, with wires sticking out in twisted, seemingly random directions. Others have deformed crystals and all of them have significant value to collectors.
How To Identify Minerals
There are a number of characteristics that are used when one identifies a mineral. Each characteristic gives an indication as to what the mineral might be, and the combination of them will point to what it is.
Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
