Here Is The Correct Way To Effectively Recognize Gold Ore

Dec 07, 2018  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.
