Gold can be found in four forms: In cave wall surface ore veins, similar to Nitra or Morkite Dropped by Loot Bugs and ...

Testing a rock for gold using magnetism is simple because gold is not attracted to magnets, unlike pyrite, which is magnetic due to its iron content. This method involves using a strong magnet, like a rare-earth magnet from a hardware store, to see if the rock reacts. While magnetism can indicate the presence of pyrite, it doesn't rule out ...

Gold sometimes occurs as a lode deposit in small amounts in rock, known as gold ore. Gold can also be found in alluvial deposits known as placer deposits, as flakes, grains, or nuggets. Ore, a naturally occurring rock or sediment with enough minerals, must be considered economically important enough to extricate. Ores can be either metals or gems.
