Murray, 1940; reported ancient copper shafts from HARTOPA (22°42'; 86°16') on both sides of the Garra Nala, RAKHA MINES (22°38'; and 86°22'), and other places. He had described an old circular shaft and a furnace from GARADI (22°43'; 86°14°). According to scholars the latest period of such workings was between the 3rd and 6th centuries A.D. Copper Hoards \[4.11\] from the adjoining Dts Mayurbhanj and Ranchi might have some connections with these ancient centres of copper production. Collection of minute particles of gold by washing the sands of the Subarnarekha had been reported by early observers in the later part of the 19th century. - [Previous: v2.c31.330](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.330) - [Next: v2.c31.332](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.332) - [Up: v2.c31](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31) --- Source: [https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.331](https://indike.org/pramana/ins.reference.ghosh-1989.v2.c31.331) · Pramāṇa
