Gold is a native element mineral, meaning that it is only made up of gold atoms. Since gold is the most malleable of all metals and is considered to be a precious metal, it is often used for jewelry, coins, artwork, and even medications. The origin of Earth’s gold content was most likely from supernova synthesis and the collision of neutron stars. It is believed that the majority of this gold sank into the core of the Earth due to Earth’s molten surface at the time of its formation. The <a href=”” rel=”noopener” target=”_blank”>Colorado Gold Rush</a> was part of many gold rushes around the world in the late 1850s and early 1860s. About 100,000 gold seekers joined in the search for riches. While most remnants of the Colorado Gold Rush have faded away into <a href=”” rel=”noopener” target=”_blank”>ghost towns</a>, others have become modern cities such as Central City, Black Hawk, and Idaho Springs.
