Gold Vein How to Find Gold in Quartz VideoRICH GOLD VEIN FOUND - Epithermal - Ironstone - Gold - Quartz - ask Jeff Williams
However, it is also possible to find veins of gold mixed with solid rock formations, usually quartz. Once you find one of these veins and collect specimens, the gold can be extracted from the quartz matrix.
However, many people enjoy making jewelry of the gold-streaked quartz just as it occurs naturally. Research potential gold-laden sites and decide on one to visit.
Visit the site you picked in step 1, bringing your hammer, chisel, water bottle, toothbrush and optional metal detector with you.
Look around for solid stretches of rock. These might be directly under your feet, or they may be in nearby hills or cliffs. If your prospecting site is near a gold-rich river or stream, keep in mind that gold is heavy and may have eroded out of the banks or any nearby high places.
It is a very heavy and strong crystalline-looking mineral that usually occurs in white, though it may also be clear, pink or gray. Set your metal detector to find gold and slowly wave it back and forth over the veins of quartz.
While this step is optional, it can help you determine where the most gold is and also provide encouragement that gold is actually there.
In many gold mines exploited during the gold rushes of the 19th century, vein material alone was typically sought as ore material.
The difference between 19th-century and 21st-century mining techniques and the type of ore sought is based on the grade of material being mined and the methods of mining which are used.
Historically, hand-mining of gold ores permitted the miners to pick out the lode quartz or reef quartz, allowing the highest-grade portions of the lodes to be worked, without dilution from the unmineralised wall rocks.
Today's mining, which uses larger machinery and equipment, forces the miners to take low-grade waste rock in with the ore material, resulting in dilution of the grade.
However, today's mining and assaying allows the delineation of lower-grade bulk tonnage mineralisation, within which the gold is invisible to the naked eye.
In these cases, veining is the subordinate host to mineralisation and may only be an indicator of the presence of metasomatism of the wall-rocks which contains the low-grade mineralisation.
For this reason, veins within hydrothermal gold deposits are no longer the exclusive target of mining, and in some cases gold mineralisation is restricted entirely to the altered wall rocks within which entirely barren quartz veins are hosted.
