BYP Mine

NEWONE2325555

Introduction

  • 70% interest acquired from a private Chinese mining company January 2011
  • Located approximately 220 km southwest of Changsha, the capital city of Hunan Province, China
  • Baiyunpu (BYP) currently under care and maintenance
  • Previous operations included a ~500 tpd ramp-supported, underground mine and a sulphide flotation plant
  • Produced lead, zinc, and gold-bearing pyrite concentrates sold to smelters in the province. From 2006 to 2014, the mine produced:
    • 1,403 t of lead at a recovered grade of 0.46%
    • 8,936 t of zinc at a recovered grade of 2.9%
    • 25,335 oz of gold at a recovered grade of 3.56 g/t
  • Production was suspended due to required capital upgrades to sustain its ongoing production and unfavourable market conditions

Silvercorp holds the surface land use rights over the 3.67 km2 Mining License area until 2063. Previous Mining License, for lead and zinc mining only, has expired. The Company is in the process of applying for a new mining permit for a gold-only operation. The process has taken longer than expected due to a provincial-wide rezoning of environmental and ecological areas. The BYP mining permit is outside of these areas. In parallel, the Company continues to explore various options for this asset.

Mining

The development of future gold operations at BYP can be fast-tracked by leveraging existing production infrastructure, including the substantially completed 265 m long shaft/headframe with a hoisting capacity of 1,000 tpd.
