Gold is a mineral that’s found in veins and placer deposits. A vein (or gold vein) is created when lava makes its way to the surface. As the lava cools, large amounts of gases and liquids are given off. Most of these liquids and gases follow cracks in the lava and deposit mineral matter along their way, forming a vein. Some of these veins can
