Serbia mining: New rich ore deposits in the vicinity of Bor

1. January 2015. / Mining

In the village of Mali Krivelj beside eastern region city of Bor, geologists from Mining and Smelting Basin Bor discovered another rich ore deposit. Based on the results obtained from five pits, the average copper content in the ore below Mali Krivelj ranges from 0.25 to 0.64 percent.

Near the village school in Mali Krivelj next to Bor, the geologists of Mining and Smelting Company find new ore deposit. Five wells have been done so far, and the results show that the copper content in the ore is from 0.25 to 0.64 percent. On the basis of these results it is expected the prognostic reserves to be about 500 million tons of ore with average copper content in the ore of 0.33 percent.

“Center of the “Mali Krivelj” deposit is near local school where copper mineralization starts from the surface of the terrain and goes up to 600 and even 800 meters of depth. It is characterized by two layers. The first starts from the surface, and goes to some 250 meters, where the copper content is 0.35%. The next is the overburden layer from 10 to 50 meters, and below it, at a depth of 300 to 500 meters is the richest ore with copper content ranging from 0.4 to 0.6 percent. In that part the gold content is above 0.2 grams per ton, which is just behind those in the “Borska reka” and better than in all other porphyry, large deposits of MSB” – says Trajce Toncic, Head of the Department of Geology IN MSB- Bor.

Geologists will continue research in this area in the next two years, in order to determine exactly how big deposit is. According to previous analyzes, the copper ore in this deposit is not so oxide, so it is extremely favorable for exploitation and flotation.
