Sahamamy
The mining operation in Sahamamy is presently a small-scale free-digging open pit operation. The mining operation comprise of historically mined open-pits as well the current open-pit operations. Based on 6-month results to 1st June 2020, a total of 116,483 t of material has been moved, of which 36,846 t had been ore material. The operating stripping ratio at this stage is about 2:1 (t:t)
The ore and the waste material are excavated and loaded by 0.70-1.0 cum bucket size backhoe and transported by a number of 5 cum Tractors (with hydraulic trailer) and 15t tipper trucks. Ore from the mine is either directly dumped at the hopper of the processing plant or at the RoM pad near the hopper.
As of the year 2020, Sahamamy has a permit to produce 3,000 tpa of processed graphite. Assuming a yield of 4.5%, the annual run-of-mine ore requirement is estimated between 60,000 tpa to 70,000 tpa. With Tirupati having plans to install a second processing plant of 18,000 tpa capacity, the combined ore requirement at peak capacity of 21,000 tpa, will be around 0.50 Mtpa.
As of 20 February 2023, Tirupati Graphite has commenced production from the 18,000 tons per annum flake graphite production facilities at its Sahamamy project. The new facilities created include new mining equipment fleet with a capacity to mine c.450,000 metric tons per annum ('tpa') run of mine graphite ore.
