VANCOUVER, BC, Jan. 12, 2022 /CNW/ - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX: SVM) (NYSE American: SVM) is pleased to report additional high-grade intercepts from its 2021 exploration program at the HPG mine. Extensive exploration drilling and tunneling are ongoing at the HPG mine and all other mines in the Ying Mining District, Henan Province, China.

From June 1 to December 31, 2021, 24,369 metres ("m") from a total of 153 diamond drill holes, including 89 underground holes and 64 surface holes, were completed at the HPG mine. Assay results for 134 holes have been received, with 82 holes intercepting mineralization. Currently, there are nine rigs drilling at the HPG mine.

The strategy of the drilling program is threefold: 1) drill above or beneath the stopes that were previously mined but stopped due to more variation in grades, thickness, and attitudes of the vein structures than previously modeled to easily obtain ore; 2) drill for gold-silver -lead-zinc veins in the resource area at higher elevations near the surface and southwest side to expand the resources; and 3) drill for a rhyolitic breccia dyke that is prominently exposed in the middle of the mining area and mineralized with gold-silver-lead-zinc.

Drilling Above or Beneath Previously Mined Stopes

Most holes drilled during this period targeted blocks containing known ore veins in production areas that were previously missed due to limited drilling or tunneling, changes in the strikes and dips, and/or pinch-swelling of the pay-zones within the veins. The high-grade intercepts are mainly associated with the southwest-striking H5 series, H15 series, H16 series, H17 series, H11, and H14 veins. Since access tunnels are already in place, any high-grade mineralization discovered can quickly be converted to reserves and mined.

Highlights of the high-grade gold-silver-lead-zinc intercepts near the surface or previously mined stopes:

• Underground hole ZK2542 intersected a 1.91 m interval (1.64 m true width) of vein H16 grading 24.66 g/t gold ("Au"), 56 g/t silver ("Ag"), 3.28% lead ("Pb"), 2.12% zinc ("Zn"), and 0.11% copper ("Cu") from 29.11 m depth, at an elevation of 527 m;
• Underground hole ZK2314 intersected a 0.75 m interval (0.48 m true width) of vein H15 grading 21.00 g/t Au, 54 g/t Ag, 0.45% Pb, 0.09% Zn, and 0.24% Cu from 132.91 m depth, at an elevation of 444 m; and
• Underground hole ZK24N04 intersected a 2.45 m interval (2.10 m true width) of vein H15 grading 0.65 g/t Au, 155 g/t Ag, 14.93% Pb, 0.03% Zn, and 0.42% Cu from 160.36 m depth, at an elevation of 549 m.

Near Surface Mineralization in Gold-Silver-Lead-Zinc Veins

Nineteen diamond drill holes were drilled from surface, with additional underground diamond drilling employed to test for near surface mineralization above 520 m within the HPG resource area. The drilling intersected gold-silver-lead-zinc veins including the H9 series, H11 series, H14 series, H15 series, H16 series, H17 series, and H10_1. The purpose of this drilling was to extend the resources to higher elevations within the current resource area.

Highlights of the high-grade gold-silver-lead-zinc intercepts near the surface or previously mined stopes:

• Surface hole ZK2419 intersected a 2.20 m interval (1.90 m true width) of vein H17 grading 22.99 g/t Au, 35 g/t Ag, 0.49% Pb, 0.07% Zn, and 0.02% Cu from 78.57 m depth, at an elevation of 817 m; and
• Surface hole ZK1218 intersected a 1.36 m interval (1.22 m true width) of vein H17 grading 10.54 g/t Au, 17 g/t Ag, 0.60% Pb, 0.02% Zn, and 0.05% Cu from 89.69 m depth, at an elevation of 783 m.

Drilling High-Grade Gold-Silver-Lead-Zinc Veins at the Southwest Side of the Resource Area

Surface and underground diamond drilling at the southwest side of the resource area intersected high-grade gold-silver-lead-zinc veins of the H20W, H12_1, H39, H41, and H40 series, at an elevation between 435 m and 655 m. These vein structures strike north to north-northeast, and have vertical to sub-vertical dips to the east. Among them, H41W is a newly discovered north-northeast striking high-grade vein that was intersected during this period.

Highlights of the high-grade gold-silver-lead-zinc intercepts at the southwest side of the resource area:

• Underground hole ZK11206 intersected a 1.33 m interval (1.10 m true width) of vein H41W grading 2.86 g/t Au, 1,469 g/t Ag, 3.69% Pb, 2.33% Zn, and 0.13% Cu from 66.90 m depth, at an elevation of 613 m;
• Underground hole ZK11207 intersected a 0.50 m interval (0.28 m true width) of vein H41W grading 0.18 g/t Au, 2,642 g/t Ag, 0.63% Pb, 0.21% Zn, and 0.09% Cu from 62.50 m depth, at an elevation of 613 m;
• Underground hole ZK11604 intersected a 1.67 m interval (1.12 m true width) of vein H40 grading 7.31 g/t Au, 100 g/t Ag, 1.78% Pb, 0.19% Zn, and 0.03% Cu from 266.55 m depth, at an elevation of 532 m; and
• Surface hole ZK11406 intersected a 0.52 m interval (0.31 m true width) of vein H20W grading 14.60 g/t Au, 15 g/t Ag, 0.07% Pb, 0.09% Zn, and 0.02% Cu from 199.41 m depth, at an elevation of 527 m.

Drilling for a Rhyolitic Breccia Dyke

The breccia dyke extends along a northwest trend for approximately two kilometres ("km"), has a thickness from 25 to 200 m, and dips steeply to the northeast.  Hole ZK1315 from this drill program intercepted a significant width of mineralization which is associated with siderite-ankerite-pyrite, and minor galena, sphalerite, and chalcopyrite in the matrix of the breccia. It is possible all the gold-silver -lead-zinc veins mined at the HPG mine have cut the breccia dyke.

Hole ZK1315 intersected an 18.41 m interval grading 1.42 g/t Au, 122 g/t Ag, 0.97% Pb, 0.56% Zn, and 0.14% Cu in the breccia (Table 1).  An earlier drill hole ZK1511 from nearby also intercepted a 31.8 m interval grading 1.14 g/t Au, 52 g/t Ag, 0.3% Pb, and 0.25% Zn.

This discovery of broad mineralization in the breccia dyke has been confirmed by a cross-cut tunnel PD2-570-15WCM, which cut a 20.7 m interval grading 1.06 g/t Au, 122 g/t Ag, 1.33% Pb, 1.48% Zn, and 0.14% Cu at an elevation of 570 m (Table 4).

Tunneling Programs at the HPG Mine                

A total of 1,436 m of exploration tunnels were developed at the HPG mine during this period. The exploration tunneling, which comprised of drifting, cross-cutting and raising, was driven along and across major mineralized vein structures to upgrade the drill-defined mineral resources, and to test for new parallel and splay structures (Tables 2 and 3).

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 three labs are ISO9000 certified analytical labs. For analysis, the sample is dried and crushed to minus 1 mm and then split into 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, while 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 CRMs, 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.

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.
