February 2016 by Chris Ralph. Most prospectors, when they think of hard rock gold deposits, think of quartz containing particles of gold. While gold deposits can be things besides quartz veins, gold is certainly found in the quartz of veins cutting through various types of rocks. Gold in quartz veins occurs as particles and scales scattered through the quartz,

Finding Gold in Quartz Rock. When gold is still encased in quartz rock, it is called a gold specimen. These are a real treat for gold prospectors and collectors as well, and are often valued at a premium due to their beauty and rarity. Hard rock mining, also known as lode mining, is obviously the best method for finding gold specimens since you are mining the true source of the gold by following veins of high
