Gold occurs principally as a native metal, i.e., gold itself.Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum.Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals.Other forms of gold are the minerals calaverite (AuTe),

However, in practical terms, copper is not magnetic enough for your fishing magnet. 3. Iron. In the case of most of the gold you attract with a magnet, it is because of the iron content that allows it to be picked up. Iron is magnetic and besides steel, it will be one of the most common metals you come across when you are out magnet fishing.
