Silvercorp's Significant Developments at the Ying Mine

Silvercorp Metals Inc. has announced a significant milestone in its operations with the completion of Tailings Storage Facility (TSF) No. 3 and a new flotation production line capable of processing 1,500 tonnes per day (tpd). These facilities are now fully operational, enhancing the mining capabilities at the Ying Mining District located in Henan Province, China.

Completion and Operations Overview

The construction of TSF No. 3 and the flotation production line was finalized in early December 2024, successfully finishing under budget and on schedule. The new flotation production line is vital as it increases the milling capacity at Ying to over 1.3 million tonnes annually, positioning the mine to handle both current and anticipated future operations.

Details of TSF No. 3

Currently, Silvercorp operates three tailings storage facilities at the Ying site. TSF No. 1 is in the process of being decommissioned, while TSF No. 2 has a remaining operational lifespan of six years. TSF No. 3 was built to initially support an operational rate of 1.3 million tonnes per year and has a substantial storage capacity of approximately 19.21 million cubic metres. This facility will accommodate the mine's environmental and operational needs for at least 12 years, ensuring safety and stability in operations.

Notably, Phase 1 of the construction of TSF No. 3 cost approximately $28 million, which is significantly lower than the original $38 million budget. This phase includes important structural features such as:

• - A non-contact water dam and discharge tunnel to manage water flow.
• - High-density polyethylene liner to prevent water contamination.
• - Monitoring and video surveillance systems for real-time assessments of the dam's stability.

Following a three-month testing period, TSF No. 3 will undergo an evaluation by the Henan Province Department of Emergency Response to secure a safety production license, adhering to local safety regulations.

Expansion of Flotation Production Line

The newly added 1,500 tpd flotation production line represents Silvercorp's commitment to enhancing productivity and operational efficiency. This production line was designed and constructed on time and within the allocated budget of $7.2 million. Using existing infrastructure from the No. 2 Mill, this expansion reduces capital expenditure while boosting operational capacity.

Equipped with advanced technology including a Knelson gravity concentrator, the new facility can produce not just silver and lead concentrates but also zinc and copper, which adds value to Silvercorp's production capabilities. After a successful commissioning period, the line achieved even higher processing capacities, reaching about 1,700 tpd, with future targets set at 1,800 tpd.

With these developments, Silvercorp anticipates a significant increase in its overall milling output at the Ying Mine, allowing for further explorations and production from nearby mining sites, such as the Kuanping mine.
