Silvercorp Metals Inc. (TSX: SVM) (NYSE American: SVM) is pleased to report results from its 2021 exploration programs at the SGX mine. Extensive exploration drilling and tunneling are ongoing at the SGX mine, and all other mines at the Ying Mining District, Henan Province, China.
From October 1, 2020 to June 30, 2021, 48,867 metres from a total of 298 diamond drill holes, including 242 underground holes and 56 surface holes, were completed at the SGX mine. Assay results for 254 holes have been received, with 166 holes intercepting mineralization.
The diamond drilling program at the SGX mine targeted: (1) blocks of known silver-lead-zinc veins; (2) blocks of silver-lead-zinc veins with gold grades but low silver-lead-zinc grades; (3) gold veins in and above the existing production areas; and (4) newly-discovered gold veins outside the production areas. Currently, 20 rigs are drilling at the SGX mine.
Drilling Intersected High-Grade Veins In and Above the Production Areas
Detailed drilling of blocks of known silver-lead-zinc and gold veins in and above the SGX mine production areas intersected high-grade veins. These mineralized occurrences were previously missed due to limited drilling and tunneling, changes in the strikes and dips, and/or pinch-swelling of the pay-zones in the veins. The Company expects that these discoveries can be converted quickly into reserves and mined with existing underground workings.
The high-grade intercepts for this period are associated with parallel silver-lead-zinc veins S7, S7_1, S7_2, S7E2, S7W1, S14, S14_1, S14_2, S14W, S16W, S16W1, S16E, S16E2, S16E8, S21, S21W1, and gold veins S16W, H18E. Other veins include S1W2, S8W2, S19, S29, S31E, S33, and S33E.
Highlights of high-grade intercepts at the SGX mine production area:
Surface and Underground Drilling Intersects Newly-Discovered Gold Veins in the North and Northeast Sides of the Resource Area
Exploratory surface drilling and underground drilling in the north and northeast sides of the resource area at the SGX mine discovered gold veins S16W, S18E, S7-2E, S7_2, S74, S74a, and S75. Gold mineralization in Ag-Pb-Zn veins, such as S16W, seems to be an earlier phase of mineralization which has been overprinted by Ag-Pb-Zn mineralization. Depending on the degree of overprint, gold grades in the Ag-Pb-Zn veins may vary substantially.

Tunneling Programs at the SGX Mine
In addition to the drilling program, 11,958 m of exploration drift tunneling were developed at the SGX mine during this period. The exploration tunneling, comprised of drifting, cross-cutting 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. The results of the exploration tunneling are summarized in the following table.

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 Chengde Huakan 514 Geology and Minerals Test and Research Institute in Chengde, Hebei Province, China, 226 km northeast of Beijing, the Zhengzhou Nonferrous Exploration Institute Lab in Zhengzhou, Henan Province, China, and SGS in Tianjin, China. All the three labs are ISO9000 certified analytical labs. For analysis, the sample is dried and crushed to minus 1 mm and then split to a 200-300 g subsample which is further pulverized to minus 200 mesh. Two subsamples are prepared from the pulverized sample. One is digested with aqua regia for gold analysis with atomic absorption spectroscopy (AAS), and the other is digested with two-acids for analysis of silver, lead, zinc, and copper with AAS.
Channel samples are collected along sample lines perpendicular to the mineralized vein structure in exploration tunnels. Spacing between sampling lines is typically 5 m along strike. Both the mineralized vein and the altered wall rocks are cut by continuous chisel chipping. Sample length ranges from 0.2 m to more than 1 m, depending on the width of the mineralized vein and the mineralization type. Channel samples are prepared and assayed with AAS at Silvercorp’s mine laboratory (Ying Lab) located at the mill complex in Luoning County, Henan Province, China. The Ying lab is officially accredited by the Quality and Technology Monitoring Bureau of Henan Province and is qualified to provide analytical services. The channel samples are dried, crushed and pulverized. A 200 g sample of minus 160 mesh is prepared for assay. A duplicate sample of minus 1 mm is made and kept in the laboratory archives. Gold is analysed by fire assay with AAS finish, and silver, lead, zinc and copper are assayed by two-acid digestion with AAS finish.
A routine quality assurance/quality control procedure is adopted to monitor the analytical quality at each lab. Certified reference materials, pulp duplicates and blanks are inserted into each batch of lab 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 and blanks to each batch of 30 core 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.
