Silvercorp Metals : INTERSECTS 7.6 METRES TRUE WIDTH GRADING 705 GRAMS PER TONNE SILVER AND 1.51% LEAD FROM VEIN LM7W AT THE LMW MINE - Form 6-K

SILVERCORP INTERSECTS 7.6 METRES TRUE WIDTH GRADING 705 GRAMS PER TONNE SILVER AND 1.51% LEAD
FROM VEIN LM7W AT THE LMW MINE

VANCOUVER, British Columbia - October 14, 2021 - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX: SVM) (NYSE American: SVM) is pleased to report thick and high-grade intercepts from its 2021 exploration program at the LMW mine. Extensive exploration drilling and tunneling are ongoing at the LMW mine, and all other mines in the Ying Mining District, Henan Province, China.

From May 1 to September 30, 2021, 23,908 metres ("m") from a total of 166 diamond drill holes, including 152 underground holes and 14 surface holes, were completed at the LMW mine. Assay results for 102 holes have been received, with 70 holes intercepting mineralization. Currently there are 12 rigs drilling at the LMW mine.

The strategy of the drilling program is threefold: 1) drill above or beneath the stopes that were previously mined but stopped due to poor understanding of the geology, such as veins LM7 and LM7W where much thicker pods have been discovered by infill drilling; 2) drill for high-grade silver-lead-zinc veins at the northwest and east sides of the resource area with previous limited drilling without follow up such as W1, W2, W6, and LM41E series veins where high grade intercepts were discovered and can quickly be mined; and 3) drill low angle gold veins such as LM50, copper-gold-silver veins such as LM26, and gold-silver-copper veins such as LM22.

Drilling Intersected High-Grade Silver-Lead-Zinc Veins at the Northwest and East Sides of the Resource Area

At the northwest side of the resource area, drilling intersected high-grade silver-lead-zinc veins W1, W2, W6, and W6E1 with true widths up to 4.67 m, at an elevation above 850 m. The drilling program discovered new splay and parallel veins, including W1E, W2E, W2W, W6W, and W18E. Vein W1 has been defined approximately 200 m along strike and 100 m down-dip, and is still open laterally along strike and at depth.

At the east side of the resource area, between the LMW mine and the LME mine, drilling intersected high-grade silver-lead-zinc vein LM41E, at an elevation above 760 m. Drilling also intersected additional splay and parallel silver-lead-zinc veins LM41E1 and LM41E1Wa, which are also high-grade vein structures with true widths up to 7.03 m.

Drill Above or Beneath the Stopes That Were Previously Mined

Most holes in this period targeted blocks of known silver-lead-zinc veins in the 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 in the veins. The high-grade intercepts are mainly associated with the northeast-striking LM7 series and LM12 series, and the northwest-striking LM8 series and LM19 series. Drilling discovered additional splay and parallel vein structures LM12_2a and T1, the latter may be a southwest extension of the major vein structure T1 at the TLP mine to the northeast of the LMW mine.

Highlights of the high-grade silver-lead-zinc mineralization at the LMW mine:

• Hole ZKX05X023 intersected an 8.87 m interval (7.60 m true width) of vein LM7W grading 705 grams per tonne ("g/t") silver ("Ag"), 1.51% lead ("Pb"), 0.08% zinc ("Zn"), 0.06 g/t gold ("Au"), and 0.05% copper ("Cu") from 24.73 m depth, at an elevation of 790 m;

Drill Low Angle Gold or Copper-Gold-Silver Veins

The drilling continued intersecting and extending the low angle gold vein LM50. An additional 17 holes in this period targeted LM50 and defined a block 800 m E-W by 500 m N-S, with hole density at the central 300 m by 300 m portion being approximately 25 m by 25 m. Another 15 holes targeted the low angle gold vein structure LM26. The assay results of 13 holes were returned with 10 holes intersecting gold mineralization.

Tunneling Programs at the LMW Mine

A total of 1,753 m of exploration tunnels have been developed at the LMW 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 to test for new parallel and splay structures (Table 2).

At the elevation of 834 m, three decline tunnels exposed low angle gold vein LM22 with ore lengths of 20 m, 18 m and 10 m, and gold grades of 26.89 g/t, 20.80 g/t and 38.95 g/t, respectively. A four-hole drilling program has been initiated to test the continuity of LM22 at the 834 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 SGS in Tianjin, China. All three labs are ISO9000 certified analytical labs. For analysis, the sample is dried and crushed to minus 1mm 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 1mm 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.

6

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.

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

8

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.
