Finding Gold Veins with a Detector AZO's: Metal

May 28, 2006 It doesn’t happen very often, but nevertheless, many gold-bearing veins have been discovered with detectors in the past 20 years. A majority have been small “pockety” strikes of native gold in quartz, or even gold in schist. Most of these shallow, surface veins are referred to by geologists as epithermal deposits.

How does Gold Naturally Form on Earth's Crust Veins

On rare occasions however, gold can be found in crystalline forms, which are very rare and highly collectable. Gold specimens of rough texture that contain quartz and other host material are also occasionally found by prospectors using gold pans, sluice boxes, and metal detectors. Gold is one of the most sought after elements on Earth.

Eight Natural Geologic Signs Pointing Toward Gold

Sep 02, 2011 Outcrops of quartz vein matter among slabby slate rock as pictured here, is a fine geologic indicator that gold could be found nearby. Know Your District The geologic concepts and indications that are the most important for finding gold vary from location to location. There is no one indicator of gold that always works.

How to find gold in quartz rock specimens

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 grade ore into the mountain.

Tourmaline-bearing quartz veins and replacement deposits, commonly copper- and gold-bearing, are found in unusual concentration in northwestern Nevada and adjacent northeastern California in Triassic and Jurassic arc rocks and in the Cretaceous plutons that intrude them.

Auriferous Deposits Mineral Processing & Metallurgy

Feb 29, 2016 The gold behavior of the several ore types can be summarized as follows: gold in placers, quartz vein gold ores, and oxidized ores are easily liberated, and can be recovered by gravity, flotation, and cyanidation; gold in copper sulphide ores is often coarse-grained and associated with copper minerals, and can be recovered into a copper

Origin of quartz-free gold nuggets and supergene gold

Jan 16, 2008 Although most quartz-bearing gold nuggets have been shed from quartz veins, supergene processes commonly upgrade the quality (fineness) of their gold. Similarly, some quartz-free nuggets can be shown to have been shed from ultramafic schists or carbonates where they were precipitated from hydrothermal fluids.

Sep 02, 2011 This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz gold bearing veins can consist of calcite or mostly sulfides which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.

These simple fissure veins usually don’t amount to much (perhaps a few tons of high grade ore), and were often overlooked by the old-time miners.

Gold and Silver Ore mined from the Motherload Quartz vein

Inside you would likely find many surfaces with visible gold. The black you see is a little bit of shale. At this particular site there seems to be a lot of slate which in itself has proven to be quite rich in gold. The quartz veins in the Mother Load district are part of whats been called the “auriferous slate belt”.

Where to Find Gold in Texas: 11 Locations Likely to Hold Gold

Quartz veins commonly occur in areas where two different types of rock are in contact with one another. Iron Staining Some gold deposits won’t be near quartz. They can also be near calcite and sulfides. The easiest way to see the presence of these minerals is by looking for iron stained spots where pyrites change to iron oxides (rust).

Twenty-Five Gold Indicators You Should Know March 2014

Many quartz veins and other hard rock gold deposits occur in “zones” that are formed along faults or at the contact of two different types of rock. This is another very productive type of indicator that has yielded a lot of gold to knowledgeable prospectors.
