VANCOUVER, BC , June 15, 2021 /CNW/ – Silvercorp Metals Inc. (“Silvercorp” or the “Company”) (TSX: SVM) (NYSE American: SVM) is pleased to report results from its 2021 exploration programs at the HPG mine. Extensive exploration drilling and tunneling are ongoing at the HPG mine, and all other mines at the Ying Mining District, Henan Province , China .

From November 1, 2020 to May 31, 2021 , 23,977 metres (“m”) from a total of 133 diamond drill holes, including 66 underground holes and 67 surface holes, were completed at the HPG mine.  Assay results for 127 holes have been received, with 51 holes intercepting mineralization. Currently, 11 rigs are drilling at the HPG mine.

Drilling Intersected High-Grade Veins in the Production Areas

The diamond drilling programs at the HPG mine targeted blocks of known silver-lead-zinc and gold veins in the production areas that 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. Since access tunnels are already in place, any discovered high-grade blocks can quickly be converted to reserves and mined.

The high-grade intercepts for this period are associated with parallel silver-lead-zinc veins H5, H5W, and H5_2, and gold veins H16, H16_3, and H171W. Other veins include H10_1, H10_1a, H11, H12_1, and H13.

Highlights of high-grade intercepts at the HPG mine production area:

  • Hole ZK01N03 intersected a 1.94 m interval ( 1.58 m true width) of silver-lead-zinc vein H5 grading 719 grams per tonne (“g/t”) silver (“Ag”), 13.09% lead (“Pb”), 5.09% zinc (“Zn”), 1.77 g/t gold (“Au”), and 0.19% copper (“Cu”) at the 373 m elevation, which includes a 1.23 m interval ( 1.00 m true width) grading 1,051 g/t Ag, 20.11% Pb, 7.58% Zn, 1.71 g/t Au, and 0.25% Cu at the 373 m elevation;
  • Hole ZK01N04 intersected a 2.89 m interval ( 2.36 m true width) of Ag-Pb-Zn vein H5W grading 150 g/t Ag, 2.91% Pb, 9.36% Zn, 0.50 g/t Au, and 0.05% Cu at the 362 m elevation, which includes a 0.76 m interval ( 0.62 m true width) grading 420 g/t Ag, 8.33% Pb, 30.93% Zn, 0.56 g/t Au, and 0.14% Cu at the 362 m elevation; and
  • Hole ZK2736 intersected a 1.16 m interval ( 1.01 m true width) of Au vein H16_3 grading 8 g/t Ag, 0.06 % Pb, 0.03% Zn, 11.80 g/t Au, and 0.01 % Cu at the 498 m elevation.

Surface and Underground Drilling Intersected High-Grade Gold Veins at Near Surface at the HPG Mine Resource Area

Surface and underground diamond drilling tested some artisanal workings in the northeast part of the HPG mining permit area and intersected high-grade Au veins. A follow-up drilling program will further test this discovery.

Highlights of high-grade, near-surface intercepts of Au vein H17 and H17_1 in the resource area:

  • Hole ZK3817 intersected a 1.45 m interval ( 1.27 m true width) of Au vein H17_1 grading 64 g/t Ag, 0.26% Pb, 0.05% Zn, 20.78 g/t Au, and 0.01% Cu at the 730 m elevation;
  • Hole ZK2410 intersected a 4.98 m interval ( 2.53 m true width) of Au vein H17 grading 16 g/t Ag, 0.06% Pb, 0.04% Zn, 9.86 g/t Au, and 0.01% Cu at the 774 m elevation, which includes a 1.06 m interval ( 0.67 m true width) grading 21 g/t Ag, 0.08% Pb, 0.02% Zn, 26.38 g/t Au, and 0.01% Cu at the 775 m elevation;
  • Hole ZK4401 intersected a 2.24 m interval ( 1.92 m true width) of Au vein H17 grading 8 g/t Ag, 0.01% Pb, 0.02% Zn, 11.39 g/t Au, and 0.01% Cu at the 696 m elevation, which includes a 1.30 m interval ( 1.11 m true width) grading 12 g/t Ag, 0.01% Pb, 0.01% Zn, 18.19 g/t Au, and 0.01% Cu at the 695 m elevation; and
  • Hole ZK2019 intersected a 1.81 m interval ( 1.68 m true width) of Au vein H17 grading 37 g/t Ag, 0.31% Pb, 0.05% Zn, 10.15 g/t Au, and 0.03% Cu at the 756 m elevation.

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 the Analytical Lab of the Inner Mongolia Geological Exploration Bureau in Hohhot, Inner Mongolia, 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 (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 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.

Guoliang Ma , P. Geo., Manager of Exploration and Resource of the Company, is the Qualified Person for Silvercorp under NI 43-101 and has reviewed and given consent to the technical information contained in this news release.

For the reasons set forth above, investors should not place undue reliance on forward-looking statements and information.

CAUTIONARY NOTE TO US INVESTORS

The disclosure in this news release and referred to herein was prepared in accordance with NI 43-101 which differs significantly from the requirements of the U.S. Securities and Exchange Commission (the “SEC”).  The terms “proven mineral reserve”, “probable mineral reserve” and “mineral reserves” used in this news release are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards (the “CIM Definition Standards”), which definitions have been adopted by NI 43-101.  Accordingly, information contained in this news release providing descriptions of our mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other U.S. companies subject to the United States federal securities laws and the rules and regulations thereunder.

Investors are cautioned not to assume that any part or all of mineral resources will ever be converted into reserves. Pursuant to CIM Definition Standards, “Inferred mineral resources” are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling.  Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity.  An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.  Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable.  Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures.

Canadian standards, including the CIM Definition Standards and NI 43-101, differ significantly from standards in the SEC Industry Guide 7.  Effective February 25, 2019 , the SEC adopted new mining disclosure rules under subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (the “SEC Modernization Rules”), with compliance required for the first fiscal year beginning on or after January 1, 2021.  The SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7.  As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”.  In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” to be substantially similar to corresponding definitions under the CIM Definition Standards.  During the period leading up to the compliance date of the SEC Modernization Rules, information regarding mineral resources or reserves contained or referenced in this news release may not be comparable to similar information made public by companies that report according to U.S. standards.  While the SEC Modernization Rules are purported to be “substantially similar” to the CIM Definition Standards, readers are cautioned that there are differences between the SEC Modernization Rules and the CIM Definitions Standards.  Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.
