Native minerals are the minerals that occur in the Earth as pure elements, not as compounds — a rarer case among minerals, most of which are actually made of more than one element.

Native metals include gold, silver, and copper, which is part of why they've been prized and worked by hand since ancient times — no chemical extraction was needed to get the pure metal.
Native non-metals exist too, such as sulfur and carbon, found in their elemental form without needing to be combined with anything else.
This makes native minerals unusual: they're the exception to the general rule that minerals are compounds, which is why gold can be called both a mineral and a metal at the same time.
