Halite, copper, diamond, calcite, talc, sphalerite, and quartz are but a few very important and economically important minerals.
This is a raw material (feedstock).
It is considered an ore as long as the locallized concentration of the mineral exceeds its crustal abondance.
Luster is typically considered the least useful mineral property, as it does not provide much information about the mineral's identity or composition. Luster simply describes how light is reflected off the surface of a mineral, such as metallic, glassy, or dull, and can vary even within the same mineral species.
Color and streak would be the least useful, because they may be shared by a multitude of other minerals.
Some of the most useful physical properties of minerals include hardness (measured on the Mohs scale), cleavage and fracture (how a mineral breaks), color, streak (color of mineral powder), luster (appearance of a mineral's surface), and crystal habit (the shape in which a mineral naturally occurs). These properties help identify and classify minerals.
A mineral that is useful and economically viable to extract and purify is an ore.
The rock would be considered an ore.

If a mineral deposit is in a remote inaccessible place where it would be too costly to remove and transport, or if the mineral was too costly to extract and purify to obtain the desired element, it would not be considered an ore. Ores are substances that can be removed and processed in an economically justifiable way to obtain the desired product.
Mineral extraction sites adjacent to the railroad line.
The term "ore" is used to refer to a mineral or rock from which a valuable or useful substance, typically metal, can be extracted profitably. Ores are important sources of metals and serve as the primary sources for many industrial processes.
The rock would be considered an ore.
