2018 10 16ensp;0183;ensp;An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The grade or concentration of an ore mineral, or metal, as well

The term metal, however, is reserved for those chemical elements that possess two or more of the characteristic physical properties of metals (opacity, ductility, malleability, fusibility) and are also good conductors of heat and electricity.
In the current gold producing zone, aligned with numerous current gold mines. High grade gravity recovered reef style gold; Known historic mining site recorded inside with high Au grade located adjacent known high grade gold mineral resources
