Copper is mined in pits ... which were underground at one point in time and are now above ground albeit at a lower elevation.
With mining gear. In or above the ground.
Copper is mined through open-pit or underground mining methods. In open-pit mining, large machinery and explosives are used to extract the ore from the earth's surface. In underground mining, tunnels are dug to access the copper ore, which is then extracted using various methods such as blasting or drilling.
Silver is mined in the ground in the same way that gold and copper is.

The larger copper mines are open pit mines. Copper ore is blasted with explosives, and loaded onto transport vehicles by heavy equipment. The ore is taken to a processing plant where it is crushed, the copper is removed chemically, and smelted into ingots of metal.
Copper is typically found at depths ranging from a few meters to a few kilometers below the Earth's surface, depending on geological conditions. It is most commonly found in deposits near the surface, but can also be mined at deeper levels through underground mining techniques.
