Yes, gold can be found in black sand. Black sand is often associated with heavy minerals like gold, as well as other minerals like magnetite and hematite. Gold prospectors may search for gold in black sand deposits as a sign of potential mineralization.
Miners used various methods to identify areas with potential gold deposits, such as studying geological maps, looking for signs of mineralization in the rock formations, observing the presence of indicator minerals, and panning for gold in nearby streams. They also relied on their experience and knowledge of the local geology to determine where gold might be found.

Nitrogen mineralization is the process by which organic nitrogen compounds present in soil are converted into inorganic forms such as ammonium (NH4+) and nitrate (NO3-), making nitrogen available for uptake by plants. This process is carried out by soil microorganisms during decomposition of organic matter.
This site really does a good job of explaining gold drill results. Great example. Useful for creating an excel document that can be used for breaking news results. http://news.goldseek.com/GoldSeek/1242751631.php
Gold can be recognized by remote sensing through the analysis of geological features associated with gold mineralization, such as alteration patterns, mineral associations, and structural controls. Remote sensing techniques like hyperspectral imaging can detect unique spectral signatures of minerals associated with gold deposits, aiding in the identification of potential gold-rich areas. Additionally, satellite imagery can be used to map out geological structures and anomalies that may indicate the presence of gold mineralization.

Yes, some garnet rocks can contain small amounts of gold within them due to their formation in mineral-rich environments. However, it is not common to find visible gold on the surface of garnet rocks as gold typically occurs in veins or grains within the rock. The presence of gold in garnet rocks can indicate potential for gold mineralization in surrounding areas.

It's "Old Gold".

Gold itself doesn't like to form chemical compounds. That's why there isn't any "gold sulfide" or "gold carbonate" or any other mineral that we mine. Make no mistake, we do mine tons of rock and process it to get out the gold. But that's because the gold is distributed through that rock as really tiny bits. Though gold does form a few compounds, we don't really see it in nature as a mineral. Hope that makes sense, and that it helps.
