Quartz reef mining - Wikipedia

Quartz reef mining is a type of gold mining in "reefs" (veins) of quartz. Quartz is one of the most common minerals in the earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. Quartz …

How to find gold in quartz rock specimens

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 grade ore into the mountain. Unfortunately, this type of mining is very expensive and not realistic for most small scale prospectors, but there are still methods …
