Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown iron-stained rock or massive white Quartz and usually contains only minute traces of gold.
Also consider that gold concentrations in ore is never consistent often occurring in pockets rather than consistently throughout. So a mine that produces some high-grade ore will also process tons of ore with almost no value. To the naked eye these ores may look exactly the same.

The main sources of gold are in hydrothermal quartz veins with pyrite and other sulfides. Gold is mechanically mixed with sulfides and not by chemical substitution. In most of the gold grain is so finely disseminated that its presence can only be detected with microscopic techniques. Plenty of 0.004 ppm in the Earths crust.

Fools Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like and weathered mica can mimic gold as well. Compared to actual gold these minerals will flake powder or crumble when poked with a metal point whereas gold will gouge or indent like soft lead. In addition actual gold will leave a golden
Oct 15 2016 This is an alternate method to using AquaRegia. The problem with using acids like this with gold ore is that other metals are almost always present in the ore with the gold so once you dissolve the gold into solution other metals are also spoiling the mix which makes removing the gold even harder to do. Sulfuric Acid will not dissolve gold.
In gold-bearing country prospectors look for gold where coarse sands and gravel have accumulated and where black sands have concentrated and settled with the gold.

That being said it would appear right now that the best way is to also look for diamonds so that you can efficiently gather gold at the same time. Be that as it may I mostly use stone which i have calculated to around 1.6 gold ores per pick which 5 picks will give me a whole number of eight ores.
Similarly large gold endowments in numerous juvenile oceanic terranes indicate an enriched SCLM cannot be the direct gold source. A crustal or subduction-zone metamorphic model remains the most viable ore-genesis model that can be applied globally with sulfur and gold released from prograde metamorphism of pyrite at depth.
