Silvercorp Metals boosts mineral reserves at China-based Gaocheng mine

The updated assessment, prepared by SRK Consulting China Ltd., highlights significant growth in the company's resource base. Measured and indicated mineral resources have climbed to 18.3 million tonnes, marking a 59% increase in tonnage compared to the 2024 technical report. This expansion includes 38.3 million ounces of silver, alongside substantial lead and zinc deposits.

Silvercorp plans to ramp up annual production from the current 345,000 tonnes to approximately 370,000 tonnes by 2029. This output level is expected to remain steady until 2041 before tapering off in the final years of the projected mine life. The company notes that the current life-of-mine plan is capped by existing tailings storage capacity, though management identifies potential for further extension if facility expansion is successfully completed. Based on these reserves, the project holds a post-tax net present value of $101.4 million at an 8% discount rate.
