how often do quartz veins have gold

Gold in Quartz February 2016 (Vol. 85, No. 06) ICMJ's

Quartz veins often fluctuate widely in value, with the richest gold ore occurring in pockets or “bonanzas” as they are sometimes called. In some mining districts the bulk of the gold is found in these rich pockets and the rest of the vein may be nearly barren.

How to Find Gold Veins & Gold Deposits in Rock Formations

Learning how to find gold veins is fairly simple to do, but you need to realize that veins of gold aren’t very common and can be fairly difficult to discover. It’s possible, though, to identify formations of quartz that have embedded gold veins, extract the gold by hand, and sell the raw gold or make jewelry out of it.

The Geology of coarse gold formation

The most common geochemistry required to dissolve gold involves sulfur, which is why sulfides like pyrite, galena and arsenopyrite are so commonly associated with gold veins. In most gold bearing veins, the gold does not form into well-developed crystals. Unlike quartz which often forms good crystals, gold requires a very specific set of

Vein (geology) Wikipedia

In many gold mines exploited during the gold rushes of the 19th century, vein material alone was typically sought as ore material. In most of today's mines, ore material is primarily composed of the veins and some component of the wall rocks which surrounds the veins.. The difference between 19th-century and 21st-century mining techniques and the type of ore sought is based on the grade of
