Color, It can point you in the right direction but color lies all the time
Rock material mined for its constituent elements or minerals is called "ore."
It is a chemical compound, possible the most useful after water. It is found in many industries and in many manufacturing processes.
A streak test is performed to identify minerals by observing the color of their powdered form. This is achieved by rubbing the mineral against a porcelain streak plate, leaving a streak of powder that can reveal the true color of the mineral, which may differ from its appearance in crystal form. The test is particularly useful for distinguishing between minerals with similar physical characteristics. Additionally, it helps in the identification process as some minerals have unique streak colors.
Ore is mined
it has rich deposits of minerals and black soil
The most useful minerals often occur in rocks and ore deposits. These minerals are typically found in areas with geological processes that concentrated them, such as near tectonic plate boundaries, volcanic regions, or areas with hydrothermal activity. Mining operations are established to extract these minerals for various industrial and commercial purposes.

A huge number of minerals are useful to human beings.

Color is generally the least useful characteristic in identifying minerals, as many minerals can come in a variety of colors. Other properties, such as hardness, streak, cleavage, and specific gravity, are more reliable indicators for identifying minerals.
People study minerals because they find out if it can be useful.
