Sažetak
(ne postoji na srpskom)
The need to open the lower parts of the ore body was caused by a number of reasons. One of the reasons is the high price of precious and non-ferrous metals on the stock market, which is far higher than the one used in calculation the technical-economic assessment in the project study on mineral reserves from 2004. Another reason for opening the lower parts of the ore body would be the remaining part of the balance reserves verified by the project study on ore reserves, not included in the main mining design on mining the ore body 'Čoka Marin - 1'.
