Exploration drilling is ongoing at the LMW mine and all other mines at the Ying Mining District in Henan Province, the company said in a statement.
From April 1, 2018 to June 30, Silvercorp said it continued its extensive exploration programs and completed 21,272 metres of underground diamond drilling and 3,274m of exploration tunneling at the LMW mine.

Results of underground drilling continuously extended the major mineralized vein structures along strike and downdip, and exploration tunneling exposed high-grade mineralization zones within major production vein structures, the company said.
Highlights of selected drill hole intersections:
- Hole ZKX11111 intersected a 1.34m interval from 135.86m to 137.20m, 0.97m true width, of vein LM17W1 grading 1,211 grams per ton (“g/t”) silver (“Ag”), 11.58% lead (“Pb”), and 0.92% zinc (“Zn”) at the 634m elevation.
- Hole ZKX1302 intersected a 1.22m interval from 121.20m to 122.42m, 1.21m true width, of a new vein grading 661 g/t Ag, 14.00% Pb, and 0.28% Zn at the 708m elevation.
- Hole ZKX0513 intersected a 1.66m interval from 185.43m to 187.09m, 1.36m true width, of vein LM17W grading 859 g/t Ag, 4.53% Pb, and 0.31% Zn at the 661m elevation.
Vancouver-based Silvercorp said the underground drilling program is being conducted with three underground rigs from the current production levels to delineate the downdip and along-strike extensions of known mineralized vein structures in the production area and test for new veins in the previously less-explored areas.
