Silvercorp Metals Inc. to Highlight Innovative Water Treatment Initiatives in Upcoming Annual Sustainability Report

VANCOUVER, Sept. 30, 2021 - Silvercorp Metals Inc. ("Silvercorp" or the "Company") (TSX: SVM) (NYSE American: SVM) is pleased to report on innovative water treatment initiatives undertaken at the Company's mines. Silvercorp strives to create "Green Mines" and pursue sustainable development initiatives throughout the mining lifecycle by integrating efficient technology and innovative systems into mine planning and ESG management practices, including in the area of water usage, a key topic for the mining industry. Silvercorp recycles and integrates treated water from its mines for use in its processing plants, dust suppression, landscaping, agriculture, and irrigation, to meet its goal of reducing freshwater consumption.

Upgraded Water Treatment Plant - SGX Mine at the Ying Mining District

Prior to the SGX Water Treatment Plant upgrade, wastewater from the SGX and HPG mines was treated with a series of precipitation ponds and manual clean up. The treated water was then transported via a 16.5 km long pipeline to the Company's central processing mill to be used in ore processing.

In November 2020, Silvercorp worked with Henan University of Science and Technology (HAUST) to implement an innovative technology to treat water from underground mines, with an investment of approximately US$0.5 million. The water treatment plant was completed in May 2021 - please see Figure 1 below. The new plant is operated through an automated control system, including a reagent mixing tank, thickening tank, precipitated materials dewatering device, and other more efficient facilities (see Figures 2 & 3) for solid waste material collection and handling. The water after treatment surpasses the standard limits as required by the Chinese national environmental law on prevention and control of water pollution, protecting surface water quality and human health, and maintaining a sound ecosystem under the Environmental Quality Standards for Surface Water (GB3838-2002).

The treated water pumped though the 16.5 km pipeline is not only used for ore processing in the mill, it can now also be used for irrigation via a newly constructed pipeline system for local farmers. The dewatered solid wastes are shipped to the mill to recover useful metals, further showing Silvercorp's firm commitment to sustainable development practices and the reduction of waste generation.
