Our visit to Khetri Nagar Jhunjhunu Rajasthan during November 2011. The history of Copper Mining at Khetri. Abstracts from the published work at Copper Mining India (1980 - 2009) is given below. Mining was flourishing at Khetri during Indus Valley civilisation. The oldest hill range of the Aravalli hills form the host for copper mineralization, giving raise to a 76 km long metallogenetic province, from Singhana to Raghunathgarh, best known as Khetri Copper Belt. Though regular mining ceased in this area by 1872, sporadic mining activity continued till 1910. With the advent of 20th century, the geologists of Geological Survey of India carried out preliminary geological work without much success. With the basic geological information in hand, Jaipur Mining Corporation entered the fray in 1944, carried out surface exploration through 4 diamond drill holes and did some aditing in the area. After holding the lease for 10 years till 1955, discouraged by the results, they wound up the programme of exploration and mining.
