Pocket Gold in Gneiss
March 2004 by Edgar B. Heylmun, PhDMetamorphic rocks such as gneiss and schist are known for their pocket gold deposits. Such pockets may not be large enough for major mining operations, but may be very rewarding for individuals or small companies. Gold-bearing quartz veins may cut gneiss or schist, but often the veins parallel the bedding, or foliation. The origin of mineralized veins, which parallel the foliation, has been kicked around for years.
...a presentation of these important trends—which coincidentally have dominated the recent news—and my resultant predictions for 2016 and beyond, will make up the majority of this column.
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
Over 7 million ounces of gold have been produced in the Klamath Mountains of northwestern California, 64% of which has been from placers.

On a personal note, very little has bothered me quite as much as the fact that some on the political left are crying “foul” about the fact that Secretary Clinton may have (the outcome is still slightly uncertain at press time) gained more popular votes than the President-elect and therefore the election result is “wrong.”
