Silvercorp Metals Inc. provides updates on the construction plan and progress on its new 3,000 tonne per day flotation mill (the "New Mill") and tailings storage facility ("TSF") at the Ying Mining District, Henan Province, China. The plan and the required regulatory approval process to build the New Mill and the TSF were announced on November 16, 2021. Currently, the Company has made progress in the following areas: agreements to lease 123.46 hectares of land have been negotiated with the local community; the environmental assessment report and safety assessment report for the TSF have been completed and filed with the local county government, and the reports for the New Mill have been drafted and are to be finalized pending completion of the preliminary engineering design of the New Mill; seven drill rigs are currently on site and 1,738 of 3,300 metres of foundation engineering survey drilling have been completed; and contractor selection to construct 5,100 metres of drain tunnels at the TSF has been initiated.

The updated budget is estimated to be approximately USD 29.8 million for the New Mill and US$38.0 million for the TSF. The New Mill will be equipped with a Knelson gold gravity separation circuit and designed to produce silver-lead, zinc, copper, and gold concentrates. The TSF may be constructed in two phases, with approximately 10.2 million cubic metres of storage capacity in Phase 1, and approximately 8.9 million cubic metres of capacity in Phase 2, for a total storage capacity of 19.1 million cubic metres.

The Company expects that construction of the New Mill will be completed by the end of 2023, and Phase 1 of the TSF by the end of 2024. The New Mill and TSF are being constructed to provide the Company with additional capacity to continue growing its existing mining operations at the Ying Mining District in light of recent successful drilling programs that have discovered new resources, to process ore from recent acquisitions, and for potential consolidation of other nearby projects. Once the New Mill is completed, the Company will decommission its No.

1 mill to have approximately 5,000 tonnes per day of milling capacity. A new training facility and R&D centre are planned at No. 1 mill site.
