Alaska Gold: Lisianski Inlet's First Bonanza
January 2019 by Norm Carson
In 1967, a local resident showed me a pouch of small gold nuggets and flakes. Several years later I asked the same person where that gold was found. He responded, “From the streambed below the old stamp mill at Apex.”
What Are Those Rocks In My Pan?
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
Northwestern Alaska Mineral Resources
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
Greenstone and Gold
Contacts, faults and zones of weak rock are all places that can act as a pipeline to convey gold-bearing fluids, leading to valuable deposits.
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.
Why Haven't They Mined This Claim?
Improvements in mining equipment and techniques, along with a higher gold price, make many mining properties profitable today that may not have been in the past.
Gemstones to Die For
Some gems can potentially poison you, make you sterile and even make you forget who you are.
Prospecting Homonyms
Three homonyms come to mind when I think of gemstones, gold and vegetables: carrot, carat and karat. Let’s look at carrot first.
