,

June 22, 2021

/PRNewswire/ – Silvercorp Metals Inc. (“Silvercorp” or the “Company”) (TSX: SVM) (NYSE American: SVM) is pleased to report results from its 2021 exploration programs at the LME mine. Extensive exploration drilling and tunneling are ongoing at the LME mine, and all other mines at the Ying Mining District,

Henan Province

,

China

.

From

October 1, 2020

to

May 31, 2021

, 17,752 metres (“m”) from a total of 113 diamond drill holes, including 98 underground holes and 15 surface holes, were completed at the LME mine.  Assay results for 102 holes have been received, with 52 holes intercepting mineralization. Currently, seven rigs are drilling at the LME mine.


Drilling Intersects High-Grade Veins in and outside the Resource Areas

The diamond drilling programs at the LME mine  targeted blocks of known silver-lead-zinc veins in the resource 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.  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 veins LM5, LM5E, LM5E1, LM5E2, M5W, and LM5W2.  Other veins include LM4W, LM4W2, LM6 and its parallel veins LM6E, LM6E2, LM6W and LM6W1.

Step-out drilling at the LME mine also hit high-grade silver-lead-zinc mineralization, including veins LM61 and LM66 to the south and vein ML18E to the north. Hole ZKG20AT1704 confirmed that the north-south striking vein T17E at the TLP mine extended southward to the area between the TLP and LME mines. These discoveries confirm the potential of high-grade silver-lead mineralization extending beyond the defined resource area of the LME mine.

Highlights of high-grade intercepts of vein LM5, LM6 and their parallel veins at the LME mine:

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.

March 31, 2020

under the heading “Risk Factors”.  Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended.  Accordingly, readers should not place undue reliance on forward-looking statements or information.


The Company’s forward-looking statements and information are based on the assumptions, beliefs, expectations and opinions of management as of the date of this press release, and other than as required by applicable securities laws, the Company does not assume any obligation to update forward-looking statements and information if circumstances or management’s assumptions, beliefs, expectations or opinions should change, or changes in any other events affecting such statements or information. 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.
