Projects
Reserve Type
- Genesis: Probably Mississippi valley type.
- Type of minerals and main minerals: Galena, Sphalerite, Pyrite in sulfide zone and Smithsonite, Hemimorphite and Cerussite in carbonate and oxide zones
- Geochemical paragenesis: Pb, Zn, Ag, Cd, Mg, Ba
Geology
- Host rock: Clastic rocks, Carbonate (Limestone, Dolomitic) and Jurassic and Cretaceous volcanic and the grade of mineral is high.

Reserve Amount
Mineral dimensions in zone no.1, which is the largest mineralization zone, is 80 * 110 meters, including several veins and lenses, carbonate and sulfide containing high grade. In zone no. 2, area is 50 * 50 meters, grade is lower, and we can see stockwork and the veins-veinlets with the relatively high density. Zone no. 3 has the area of 20 * 30 meters with high grade and zone no. 4 has the area of 90 * 80 meters, the grade is high and the total amount of lead and zinc grade is 5.2%.
Proven Reserve
According to exploratory operations in this area, the proven reserve is about 1.436.000 tones with the average grade of 5.2 percent of the total lead and zinc and the amount of silver and cadmium is significant. The probable reserve is about 3,000,000 tons with the average grade of 4 percent lead and zinc.
