("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.
