Insights

Geologist

The reported high-grade gold-silver-lead-zinc intercepts by Silvercorp Metals Inc. from its ongoing diamond drilling program at the HPG mine in the Ying Mining District, China, are significant for several reasons. Firstly, the core lengths and grades of precious and base metals such as gold (Au), silver (Ag), lead (Pb), zinc (Zn) and copper (Cu) are indicative of the mineralization potential of the mine. The presence of high-grade intercepts can imply substantial in-situ value, which is critical for the mine's economic viability.

Secondly, the volume of drilling activity, with a reported 45,046 m in 297 diamond drill holes, suggests an aggressive exploration and potential resource expansion strategy. The results from the assays of these drill holes could lead to an update of the resource estimate, which is a key driver for stock valuation in the mining sector.

Lastly, the identification of new ore bodies such as the B8 within the breccia zone and the confirmation of the down-dip extension of major vein structures may lead to an extension of the mine's life and an increase in its production profile. These factors are generally viewed positively by investors as they may lead to increased revenue and profitability for the company in the long term.

Financial Analyst

The exploration results released by Silvercorp Metals Inc. can have a material impact on the company's financials, particularly if the findings lead to an increase in the proven and probable reserves. The reported grades, especially the high silver content in some intersections, such as 6,132 g/t Ag, are substantially higher than the global average for silver mines, which typically ranges from 50 to 300 g/t Ag. This could translate into lower production costs per ounce of silver equivalent, potentially improving profit margins and the company's cost competitiveness.

Investors will be interested in how these results will affect Silvercorp's production guidance and cost forecasts. The market often reacts to such announcements with increased trading volumes and price volatility, as investors reassess the company's growth prospects. It is important to note, however, that mining is a capital-intensive industry with significant lead times from discovery to production and thus the short-term impact on financials may be limited compared to the long-term potential.

Mining Sector Analyst

The details provided by Silvercorp Metals Inc. regarding their drilling program can be viewed as a strategic move to strengthen their mineral inventory and potentially extend the life of the HPG mine. The focus on three main areas—upper zone, production zone and breccia zone—highlights a comprehensive approach to understanding the deposit's geology and optimizing the extraction process. The market often looks favorably upon companies that demonstrate proactive management of their assets and a clear strategy for growth.

Furthermore, the adoption of a rigorous QA/QC program in their assay processes reflects industry best practices, which is crucial for investor confidence in reported data. Companies that can reliably report their exploration results tend to maintain or improve their market reputation, which can be reflected in stock performance. Overall, the drilling results may be a positive catalyst for the company, pending the integration of the new data into their overall resource estimates and mining plans.

From January 1, 2022 to November 15, 2023, a total of 45,046 m in 297 diamond drill holes, including 215 underground holes and 82 surface holes, were completed at the HPG mine. Assay results for 270 holes have been received, with 139 holes intercepting mineralization. Currently, there are 8 rigs drilling at the HPG mine.

The drilling program at the HPG mine has been focused on three main areas (Figure 2): 1) near surface gold-silver-lead-zinc (Au-Ag-Pb-Zn) vein structures within the resource area which have seen limited exploration drilling and tunneling (upper zone - U); 2) infill drilling above or below previously-mined stopes where production stopped due to higher than expected variability in grades, vein thicknesses, and attitudes of the vein structures (production zone - P); and 3) testing the Au-Ag-Pb-Zn mineralization potential and extent within a rhyolitic breccia dyke that is situated within the current underground mining infrastructure (breccia zone - B).

Drilling Near Surface Au-Ag-Pb-Zn Vein Structures within the Resource Area – Upper Zone (U)

Previous drilling was primarily focused on testing the strike and downdip extent of known vein structures with a limited focus being placed on the up-dip potential at shallower elevations above 600 m above mean sea level ("amsl"). Extensive drilling from surface and underground drill carbines yielded intercepts of high-grade Au-Ag-Pb-Zn vein structures at higher elevations, which include the H13 series, H15 series, H16 series, H17 series, H32 series, H42 series, H5, H13, H14, H18, and H29 (Table 1).

Drilling Above or Beneath Previously-Mined Stopes within the Resource Area – Production Zone (P)

The majority of the drilling campaign targeted areas of known Au-Ag-Pb-Zn vein structures that were previously underexplored due to higher than expected variation in the thickness and trend of the high grade ore shoots of the veins within the resource areas below the 600 m amsl elevation. The high-grade intercepts are mainly associated with the northwest-dipping H5 series, H 15 series, H16 series, H17 series, H11, H13, and H14, and the east-dipping H20 series, H41 series, H32 series, H29, H40 and H42 veins. These intercepts have led to significant expansion and upgrading of high-grade resources (Table 2).

Testing Au-Ag-Pb-Zn mineralization within the Rhyolitic Breccia Dyke – Breccia Zone (B)

Drilling has been ongoing to test the mineralization within a northwest trending rhyolitic breccia dyke (breccia zone B8) (Table 3) hosting disseminated Au-Ag-Pb-Zn-Cu mineralization across a currently defined zone measuring 50 m long, 30 m high, and 20m wide. The newly discovered B8 orebody has been mined since October 2023 by means of long-hole stoping.

In addition to the drilling outlined above, which focused on drilling vein structures within the current mining infrastructure, some drillholes were aimed at testing the down-dip extension of major vein structures including H15, H16, and H17 below 300 m amsl elevation within the Deep Zone (zone D). Initial drilling confirmed notable mineralization and down dip extension of mineralization along the targeted vein structures (Table 4).

Quality Control

Drill cores are NQ size. Drill core samples, limited by apparent mineralization contacts or shear/alteration contacts, were split into halves by sawing. 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 by two-acid digestion 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.

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 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.
