Silvercorp Expands Mineralized Zones at the GC Mine

VANCOUVER, British Columbia – November 13, 2019 – Silvercorp Metals Inc. ("Silvercorp” or the “Company”) (TSX/NYSE American: SVM) is pleased to report results of its exploration programs at the GC silver-lead-zinc mine, Guangdong Province, China. Exploration drilling is ongoing at the GC mine.

From October 1, 2018 to September 30, 2019, Silvercorp continued the extensive exploration programs at the GC mine and completed 25,877 metres (“m”) of diamond drilling with three underground rigs from current production levels, and 14,243m of exploration tunneling between elevation levels -300m and 150m. The drilling program was successful in extending the major mineralized vein structures along strike and downdip, and exploration tunneling exposed high grade mineralized zones within major production vein structures. During this period, over 40 parallel and splay structures were discovered near the major mineralized zones at the GC mine and the discovery of west-east striking mineralized vein V58 expanded the mineralized zones approximately 100m to the south from the existing resources.

Highlights of selected drill hole intersections:

  • Hole 19CK26A03 intersected a 0.82m interval from 36.73m to 37.55m, 0.46m true width, of vein V7 grading 300 grams per tonne (“g/t”) silver (“Ag”), 16.54% lead (“Pb”) and 4.14% zinc (“Zn”) at the -210m elevation;
  • Hole 19CK40A01 intersected a 1.01m interval from 70.79m to 71.80m, 0.73m true width, of newly discovered vein V52 grading 365 g/t Ag, 2.46% Pb and 12.96% Zn at the 146m elevation;
  • Hole 19CK2404 intersected a 2.52m interval from 73.35m to 75.87m, 2.47m true width, of newly discovered vein V2W-13 grading 319 g/t Ag, 3.75% Pb and 6.70% Zn at the -232m elevation; and
  • Hole 19CK4001 intersected a 1.21m interval from 93.33m to 94.54m, 1.03m true width, of vein V13 grading 566 g/t Ag, 2.23% Pb and 2.58% Zn at the 143m elevation.

The drilling program is mainly conducted 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 vein structures in the previously less-explored areas.

The program is summarized in the following table:

Highlights of selected mineralized zones exposed in the drift tunnels:

  • Drift Tunnel V5-9-(-50)-30NEYM exposed mineralization 60m long and 1.09m wide (true width) grading 357 g/t Ag, 4.72% Pb and 10.08% Zn within vein structure V5-9 on the -50m level;
  • Drift Tunnel V19-(-75)-42WYM exposed mineralization 28m long and 0.91m wide (true width) grading 234 g/t Ag, 13.56% Pb and 6.42% Zn within vein structure V19 on the -100m level;
  • Drift Tunnel V52-150-119NEYM exposed mineralization 50m long and 0.86m wide (true width) grading 454 g/t Ag, 3.88% Pb and 7.39% Zn within newly discovered vein structure V52 on the 150m level; and
  • Drift Tunnel V32-0-50ANEYM exposed mineralization 73m long and 0.40m wide (true width) grading 635 g/t Ag, 4.57% Pb and 3.54% Zn within vein structure V32 on the 0m level.

The exploration tunneling, comprising drifting, crosscutting and raising, was driven along and across major mineralized vein structures to upgrade the drill-defined mineral resources and test for new parallel and splay structures, and summarized in the following table:

Tables 1 and 2 below list the assay results of selected mineralized drill hole intersections and certain mineralized zones exposed in drift tunnels from the exploration programs.

Quality Control

Drill cores are NQ size. Drill core samples, limited by apparent mineralization contacts or shear/alteration contacts, were split into halves by saw cutting. The half cores are stored in the Company's core shacks for future reference and checks, and the other half core samples are shipped in securely sealed bags to the on-site laboratory.

Channel samples are collected along sample lines perpendicular to the mineralized vein structure in exploration tunnels. Spacing between sampling lines is typically 5m along strike. Both the mineralized vein and the altered wall rocks are cut by continuous chisel chipping. Sample length ranges from 0.2m to more than 1m, depending on the width of the mineralized vein and the mineralization type. Channel samples are shipped in securely sealed bags to the on-site laboratory.

For analysis, the sample is dried and crushed to minus 1mm and then split to a 200-300g subsample which is further pulverized to minus 200 mesh. Two subsamples are prepared from the pulverized sample. One is digested with two-acids for analysis of silver, lead, zinc and copper with atomic absorption spectroscopy (AAS), and the other is retained as pulp reject at the lab for future reference.

A routine quality assurance/quality control (QA/QC) procedure is adopted to monitor the analytical quality at each lab. Certified reference materials (CRMs), pulp duplicates and blanks are inserted into each lab batch of samples. QA/QC data at the lab are attached to the assay certificates for each batch of samples.

The Company maintains its own comprehensive QA/QC program to ensure best practices in sample preparation and analysis of the exploration samples. Project geologists regularly insert CRM, field duplicates, reject duplicates and blanks to each batch of 30 samples to monitor the sample preparation and analysis procedures at the labs. The analytical quality of the labs is further evaluated with external checks by sending approximately 3-5% of the pulp samples to higher level labs to check for lab bias.

Data from both the Company's and the labs' QA/QC programs are reviewed on a timely basis by project geologists.
