Most common would be azurite and clinoclase.
Copper is created in nature through a process called hydrothermal mineralization. This occurs when hot, metal-rich fluids rise from deep within the Earth's crust and deposit copper minerals in cracks and crevices of rocks. Over time, these deposits can accumulate and form copper ore bodies that can be mined for copper extraction.
In subsurface mining, tunnels are dug beneath the Earth's surface to extract valuable minerals or resources, such as coal, gold, or copper. These tunnels can extend deep underground to reach the ore deposits, which are then brought to the surface for processing and use.
Subsurface mining is a method used to extract minerals and ores that are located deep underground. It involves creating tunnels and shafts to access the deposits and extract the resources. This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.
Deep shaft mining is a method of extracting minerals and resources from deep underground by digging vertically downward, creating a shaft that allows miners and equipment to access the deposits. This method is commonly used for accessing resources such as coal, gold, and copper that are located deep beneath the Earth's surface.
Opencast mining involves extracting minerals from an open pit, while shaft mining involves digging tunnels or shafts deep underground to access mineral deposits. Opencast mining is typically used for shallow mineral deposits, whereas shaft mining is used for deeper deposits that cannot be easily accessed from the surface.
Azurite.
Azurite is a deep blue mineral. It is often associated with copper deposits.

It is not less expensive. Deepwater operations take considerably more money. Multiple contractors and firms have to come together to overcome vast depths. The added risks involved also mean more costs.

This method is commonly used for accessing resources such as coal, gold, and copper that are located deep beneath the Earth's surface.

Minerals that produce deep red colors include cinnabar (mercury sulfide), cuprite (copper oxide), vanadinite (lead chlorovanadate), and rhodonite (manganese silicate). These minerals derive their red color from the presence of specific chemical elements or compounds in their crystal structures.
Deep mining involves extracting minerals and resources from deep underground deposits, typically several thousand feet below the Earth's surface. This method requires extensive digging and drilling to reach the desired resources. Deep mining poses significant challenges regarding safety, ventilation, and ground stability.
Deep mining is typically used when mineral deposits are located at significant depths underground, where surface mining methods are not feasible. It is also employed when valuable resources are present at depths that require underground extraction, such as coal, gold, diamonds, and precious metals. Deep mining is an essential practice to extract minerals that are located deep beneath the Earth's surface.
