Because that is where most of them are. There are also small mountains above the surface that can be surface mined.
ore deep beneath earth's surface is mined by drilling holes in the earth's crust so that mines can be built for excavation in which the ore is generally mined near but not to close to the base of a dormant volcano as not to activate the volcano.
Metals found in the Earth's crust must typically be mined and extracted from their ores in order to be utilized. Through mining processes, the ores are extracted and then undergo various separation techniques to isolate the desired metal for industrial and commercial applications.
Surface mining: extracting minerals or ores from the surface of the Earth. Underground mining: extracting minerals or ores from beneath the Earth's surface. Placer mining: extracting minerals or ores from rivers, streams, or other sediment deposits. Submarine mining: extracting minerals or ores from the seabed.
Minerals are mined in regions where they occur as ores because ores have a higher concentration of the desired mineral, making extraction more economical and feasible. Mining in regions where minerals occur as ores also reduces the need for extensive processing to extract the desired mineral.
When ore is too deep within the earth to be surface mined, underground mining methods are used. This involves creating tunnels and shafts to access the ore deposits beneath the surface. Various methods such as drift mining, shaft mining, and room and pillar mining can be utilized based on the specific geological conditions.
Ores near the surface will be quarried or opencast mined.

Ores that are near the Earth's surface can be obtained by scraping away the soil, blasting the ore into small pieces, and removing it with heavy equipment and taking it to smelting plants. Ores that are located deep in the Earth must be mined from tunnels in deep rock.
With in the mountainous body and beneath the earth surface.
either pegmatites, quarries, surface minerals, or ores.

From various minerals and ores which are mined. Which metal depends on which mineral is mined.
Ores deep beneath the Earth's surface are removed through a process called mining. This involves creating tunnels and shafts to access the ore deposits, which are then extracted using various methods such as drilling, blasting, and hauling. Once the ore is brought to the surface, it is processed to extract the valuable minerals.
