Detailed explanation-3: -As time passed, the gold started getting more below the surface. In the early 1900s, where gold was being found at a distance of 1 km from the surface, by the year 1980, it went to 3 km depth from the surface, that is, about 10 km from the ground. At that time KGF became the second deepest gold mine in the world.
Detailed explanation-4: -Champion, the deepest, reached some 10, 500 feet (3, 200 metres) below sea level. Although the annual production in some years was more than 95 percent of India’s gold output, the mines declined and were nationalized in 1956 to prevent closure.
