Three things I need to mention: 1) Not all white quartz will contain gold lines. 2) Gold is also found in non-rusty quartz. 3) Some thicker (cruder) gold lines will be iron pyrite. The reason we do the scratch test is to determine if we have

Gold is dense and heavy, it has a characteristic metallic color, and it is soft and easily malleable (it is easily formed by hammering). These are the characteristics used by prospectors to identify gold in the field. Lode gold occurs on the claim usually in quartz veins derived from gossan formed by weathering, and oxidation of the gold

Quartz Reef Mining. Primary gold typically happens in quartz veins. The removal of gold ore from these tough quartz veins was traditionally referred to as quartz reef mining. A Prussian engineer, Jacob Brache was the foremost to feel that quartz reefs may have even more gold than alluvial fields. The novel mining firms had to sink very profound

Nice gold in quartz specimens are highly valued by mineral collectors. Since each specimen is unique, there are never two that are the same, and they can be spectacular pieces to add to your collection. By doing some research and using the proper methods, it is still possible for prospectors to find these rare beauties.

Reef prospecting entails locating gold bearing quartz veins. The majority of the accessible reefs have most likely been found by early prospectors and explorations; as a result, remote and poorly outcropping reefs are more probable to be found. These days, in the short term, this form of prospecting is not as rewarding as metal noticing.
