Ground water is naturally pure and is a reliable source of water. Ground water is every where and it just depends how deep it is.
Deep mining of any kind is done in tunnels leading off a vertical shaft into the ground, as opposed to 'open pit' or 'strip' mining. Deep mining is principally done for copper.
It can be found (considerably shallow) 200 ft. Deep underground would be around 1000 ft.
Native copper can be found in alluvial deposits, granitic and basaltic rock. The biggest ores of copper are the minerals chalcopyrite and malachite. Copper is mined throughout the world and the open pit mines created are the largest man-made excavations in the world. The top copper mining countries are Chile, U.S.A., Peru, China, Australia, Indonesia, Russia, Canada and Zambia. Copper is found in many other countries as well, it's a pretty extensive list. Trace amounts of copper can be found in our blood - it is an essential enzyme that helps the central nervous poooooooooooooooooooooooooooooooooooooooooooooooooo.

Copper is an element. It is a natural mineral found in the ground. It is extracted from the ground by mining similar to the mining of gold or iron.
Deep in the ground.
Nitrogen,iron,aluminium,sulphur,copper,magnesium,zinc,etc. are found in the ground.

In ores. Copper ores are found in various parts of the world. Copper can be found as a metal in the ground. Normally, it is green on the outside. Most copper is not as a metal but in chemical compounds. Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things. Some mollusks and arthropods have blue blood because they have copper in their blood. Animals such as humans and other mammals have red blood because it contains iron. Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper sulfate - sometimes spelt sulphate. Pure copper forms on the negative electrode.
The bare copper conductor found in non metallic sheathed cable is the ground wire. On a wire count in a cable set the ground wire is never counted even though it is always there.
I have found that anything under ground can go bad after a while. But the worst thing for under ground pipes is for it ( copper ) to be touching each other and touching cement or rocks
