Mining claims are staked for locatable minerals on public domain lands. Locatable minerals include both metallic minerals (gold, silver, lead, etc.) and nonmetallic minerals (fluorspar, asbestos, mica, etc.). It is nearly impossible to list all locatable minerals because of the complex legal requirements for discovery.

For the NRSA-based indicators, the minerals and metals sector includes activities involved in: Extracting and initial processing of mineral products (also referred to as primary production): Extraction of coal, metallic minerals (e.g. copper, gold, lead, nickel, silver and zinc), and non-metallic minerals (e.g. diamonds, potash, salt and stone)
The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods. People have extracted minerals, for example iron and copper, from ores for thousands of years. Examples of how minerals were mined long ago can be found at archaeological sites in South-Africa, such as Mapungubwe.
