(2) Brief introduction of achievements

The upper marble lead-zinc ore body has been exposed in line 99 and line 107. The length of the controlled ore body is 350 ~ 600 meters, the dip depth is more than 600 meters, and the maximum thickness of the ore body is 60.75 meters. The main minerals are lead and zinc, and the main minerals are sphalerite, galena and magnetite.

* * * The discovered lead and zinc resources (3.32+333) are about: lead metal148,400 tons, with an average grade of 0.67%, zinc metal 683,200 tons, with an average grade of 3.08%, of which (332) resources13,600 tons, with an average grade. (333) resources: lead metal134,800 tons, with an average grade of 0.65%, zinc metal 626,400 tons, with an average grade of 3%, accounting for 9 1.53% of (332+333) resources. After 20 13 years of work, 462,800 tons (332+333) of lead and zinc metals were added. According to the assessment, the deposit is very large.
