Trading Symbol: TSX/NYSE American: SVM

VANCOUVER, BC, June 12, 2026 /CNW/ - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX: SVM) (NYSE American: SVM) is pleased to report the results of an updated Technical Report ("Ying 2026 Technical Report" or "Technical Report") titled "NI 43-101 Technical Report Update on the Ying Ag-Pb-Zn-Au Property in Henan Province, People's Republic of China", prepared in accordance with National Instrument 43‑101 Standards of Disclosure for Mineral Projects ("NI 43-101") by AMC Mining Consultants (Canada) Ltd. ("AMC") with a Mineral Reserve and Mineral Resource effective date of December 31, 2025. The Ying 2026 Technical Report covers seven underground mines (namely SGX, HZG, HPG, TLP, LME, LMW, and DCG) and the KP underground mine start-up in the Ying Mining District (also collectively referenced as the "Ying Property" and "Ying Mining District").

Approximately 106 million ounces (Moz) of silver ("Ag") plus lead, zinc, and gold are projected to be mined at the Ying Property in the currently planned 17-year life of mine (LOM). There remains significant potential to extend the LOM beyond 2042 via further exploration and development, particularly in areas with identified Inferred Resources.

Silvercorp Main Observations to the Independent Ying 2026 Technical Report:

Lower cut-off grades were applied due to a higher silver price used ($28/oz in 2026 vs $21/oz in 2024).

The 2026 Mineral Reserves reflect the replenishment of metals mined-out between June 2024 (effective date of 2024 Technical Report) and December 2025, with approximately 9.8 million ounces of silver ("Moz Ag"), 12.6 thousand ounces of gold ("koz Au"), 38.6 thousand tonnes of lead ("kt Pb") and 5.1 thousand tonnes of zinc ("kt Zn") produced.

Ying Mining District LOM metal production AgEq values, which only consider silver plus conversion of gold ounces to equivalent silver ounces^[1], are shown in Table 1.

Mineral Resources

The December 2025 Mineral Resources were estimated using a block modelling approach in Datamine or Vulcan software for a total of 591 mineralized vein structures for the eight deposits in the Ying Mining District. All grade estimation was completed using inverse distance squared. Grade estimates were completed for silver and lead in all deposits, zinc in select deposits, and gold within select veins at select deposits.

The Mineral Resources are reported above cut‐offs after applying a minimum practical extraction width of 0.4 m. Diluted grades were estimated for blocks with mineralization widths less than 0.4 m by adding a waste envelope with zero grade. Cut‐off grades are based on either in situ values in silver equivalent (AgEq) or gold equivalent (AuEq) terms in grams per tonne and incorporate mining, trucking, and processing costs, with metallurgical recoveries and payable values provided by Silvercorp for each mine and reviewed by the QPs. Equivalency formulas by deposit are shown in the footnotes of the table below.

The estimated Mineral Resources and metal content for the Ying Mining District as of December 31, 2025 are detailed in Table 2 below.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted to Mineral Reserves.

A comparison of Mineral Resource estimates between June 30, 2024 and December 31, 2025 indicates the following:

• Measured and Indicated tonnes have increased by 90% overall. The Inferred tonnes have increased by 54%.
• Measured and Indicated grades have decreased for Ag and Au by 28% and 15%, respectively. Measured and Indicated grades have decreased for Pb by 27% and Zn by 22%.
• Inferred grades decreased for Ag, Au, Pb, and Zn by 42%, 38%, and 9%, respectively.
• The net result in the Measured and Indicated categories has been an increase in the contained Ag and Au of 37% and 62% respectively. Contained Measured and Indicated Pb and Zn have increased by 39% and 48% respectively.
• The net result in the Inferred category has been a decrease in the contained Ag, Au, and Pb of 1%, 10%, and 4% respectively. Inferred Zn has increased by 40%.

The reasons for the differences in grade, tonnes, and contained metal include changes made to vein interpretations for the 2025 Q4 model, conversion to higher categories arising from drilling and level development, application of different COGs and depletion due to mining. The QPs note that metal prices have increased by 67% for Ag, 78% for Au, 3% for Pb, and 36% for Zn. This has resulted in a reduction in COGs for all deposits. 

Mineral Reserves

The Mineral Reserve estimation assumes that current stoping practices will continue to be predominant at the Ying property, namely cut and fill resuing and shrinkage stoping for most veins, using hand-held drills (jacklegs) and hand-mucking within stopes, and loading to mine cars by rocker-shovel or by hand. The QP also recognizes the increased use of more mechanized mining techniques at the Ying operations. The typically sub-vertical veins, generally competent ground, reasonably regular vein width, and generally hand-mining techniques using short rounds, allow a significant degree of selectivity and control in the stoping process. Minimum mining widths of 0.5 m for resuing and 1.0 m for shrinkage are assumed. The QP has observed the resuing and shrinkage mining methods at the Ying property on several occasions and considers the minimum extraction and mining width assumptions to be reasonable. Minimum dilution assumptions are 0.10 m of total overbreak for a resuing cut and 0.2 m of total overbreak for a shrinkage stope. Average Ying dilution projections for resuing and shrinkage are 17% and 20%, respectively. Mining recovery factors assumed as 95% for resuing and 92% for shrinkage, room and pillar, and longhole.

The QP notes that, for a small number of veins with relatively low-angle dip – generally veins with significant gold content – room and pillar stoping with slushers is now being used at the Property. Longhole stoping has also been recently employed in some areas of the LMW mine.

Recent initiatives at the Ying operations have resulted in a +20% increase in annual production in the last two years, with additional mine expansion activities also underway. In the future, the Ying operation plans to develop deeper mining zones within each mining area, as part of an aim to further enhance overall production rates. An increased use of trackless equipment in some mine areas and a focus on more mechanized mining will be a key part of future mine planning.

For the total tonnage estimated as Ying Mineral Reserves, approximately 64% is associated with resuing, 32% with shrinkage, 3% with room and pillar, 1% with longhole.

The sensitivity of the Ying Mineral Reserves to variation in COG has been tested by applying a 20% increase in COG to Mineral Reserves at each of the Ying mines. The lowest operating mine sensitivity continues to be seen at SGX. For the entire Ying Mining District, an approximate 16% reduction in AgEq ounces for a 20% COG increase demonstrates moderate overall COG sensitivity.

Total Ying Mineral Reserve tonnes are approximately 45% of Mineral Resource (Measured plus Indicated) tonnes. Ag, Au, Pb, Zn, and Cu Mineral Reserve grades are 119%, 103%, 110%, 119%, and 50%, respectively, of the corresponding Measured plus Indicated Mineral Resource grades. Metal conversion percentages for Ag, Au, Pb, Zn, and Cu are 54%, 46%, 50%, 53%, and 24%, respectively.

Some significant aspects of a comparison of Mineral Reserve estimates between June 30, 2024 (previous Technical Report) and December 31, 2025 (Ying 2025 Technical Report) are the following:

• 50% increase in total (Proven + Probable) Ying Mineral Reserve tonnes: 45% increase in Proven Mineral Reserves and 55% increase in Probable Mineral Reserves.
• 1% increase in Ying Mineral Reserve Au grade and reductions of 20%, 23%, and 17% in Ag, Pb, and Zn grades, respectively. Increase in Ag, Au, Pb, and Zn metal content of 20%, 52%, 16%, and 22%, respectively.

Economic analysis

A high-level economic analysis shows the potential economic impact relative to the latest Mineral Reserve estimations and the associated production schedules. The following Ying realized selling metal prices (Ying averages over projected LOM except where stated), average costs, and exchange rate were used for the economic analysis (all values in $US):

• Gold price / troy ounce	$3,400 FY2026Q4, $2,975 FY2027, $2,800 LOM
• Silver price / troy ounce	$76.80 FY2026Q4, $48.00 FY2027, $38.40 FY2028, $26.88 LOM
• Lead price/lb	$0.90
• Zinc price/lb	$1.92
• Copper price/lb	$1.76
• Mining cost/t	$75.43
• Milling cost/t	$12.40
• Shipping cost/t	$3.06
• Mineral Resources tax & rights royalty/t	$9.87
• G&A/t	$7.05
• Government fees and other taxes/t	$3.52
• Sustaining and growth capital/t	$19.08
• Exchange rate	US$1 = CYN7.00

The QP notes the following about the above economic parameters:

• Ying realized metal prices are as per Silvercorp advice and assume the following $US market prices:
  Gold/oz: $4,000 FY2026Q4, $3,500 FY2027, $2,800 remaining LOM
  Silver/oz: $80 FY2026Q4, $50 FY2027, $40 FY2028, $28 remaining LOM
  Lead/lb: $0.90
  Zinc/lb: $1.20
  Copper/lb: $4.40
• Other than for FY2026Q4 / FY2027 for gold, and FY2026Q4 / FY2027 / FY2028 for silver, the above market prices are as per those used in the mining COG calculations.

The QP also notes that approximate spot metal prices at the time of writing of the Technical Report are: gold - $4,745/oz; silver - $75.50/oz; lead - $0.86/lb; zinc - $1.49/lb, copper - $5.85/lb.

Based on the LOM production profile and the metal price and other assumptions shown above, pre‑tax and post-tax cashflow projections have been generated. At a 5% discount rate, pre‑tax and post-tax net present values (NPVs) of $1,275M and $1,030M, respectively, are projected. Over the LOM, 69.3% of the net revenue is projected to come from silver, 20.1% from lead, 5.4% from gold, 4.6% from zinc, and 0.6% from copper.

The Ying mine complex is seen to be a very viable operation with a projected LOM through to 2042 based on Proven and Probable Mineral Reserves. There remains significant potential to extend the LOM beyond 2042 via further exploration and development, particularly in areas with identified Inferred Resources.

CAUTIONARY NOTE TO US INVESTORS

 The technical and scientific information contained herein has been prepared in accordance with NI 43‐101 and the Canadian Institute of Mining, Metallurgy and Petroleum classification system, which differs significantly from the standards adopted by the U.S. Securities and Exchange Commission (the "SEC"). Accordingly, the technical and scientific information contained herein, including any estimates of mineral reserves and mineral resources, may not be comparable to similar information disclosed by U.S. companies subject to the disclosure requirements of the SEC. In particular, and without limiting the generality of the foregoing, this news release uses the terms "measured resources," "indicated resources" and "inferred resources" as defined in accordance with NI 43-101 and the CIM Standards.

Further to recent amendments, mineral property disclosure requirements in the United States (the "U.S. Rules") are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the "U.S. Securities Act") which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the "MJDS"), the Company is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If the Company ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then the Company will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.

 Pursuant to the new U.S. Rules, the SEC recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the definitions of "proven mineral reserves" and "probable mineral reserves" under the U.S. Rules are now "substantially similar" to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are "substantially similar" to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM 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 U.S. Rules.
