Owners

CompanyInterestOwnership
Silvercorp Metals Inc. 80 % Indirect
Silvercorp, through its wholly owned subsidiary Victor Mining Ltd, is party to a cooperative joint venture agreement dated 12 April 2004 under which it earned a 77.5% interest in Henan Found Mining Co. Ltd (Henan Found), the Chinese company holding (with other assets) the Ying silver, lead, and zinc project (the Ying Project). In addition, Silvercorp, through its wholly owned subsidiary Victor Resources Ltd, is party to a cooperative agreement dated 31 March 2006, under which it initially obtained a 60% interest in Henan Huawei Mining Co. Ltd (Henan Huawei), the beneficiary owner of the project in Haopinggou (the HPG Project) and the project in Longmen (the LME Project). Since that time, Silvercorp’s interest in Henan Huawei has increased to 80%.

Deposit Type

  • Mesothermal
  • Vein / narrow vein


Summary:

Mineralization The Ying Property contains multiple mesothermal silver-lead-zinc-rich quartz-carbonate veins in steeply-dipping fault-fissure zones which cut Archean gneiss and greenstone. To date, significant mineralization has been defined or developed in at least 308 discrete vein structures, and many other smaller veins have been found but not as yet well explored. Structurally, the vein systems throughout the district are all somewhat similar in that they occur as sets of veins of generally similar orientation enclosed by fault-fissure zones which trend most commonly northeast-southwest, less commonly north-south, and rarely northwest-southeast. The structures extend for hundreds to a few thousand metres along strike. They are often filled by altered andesite or diabase dikes together with quartz-carbonate veins or as discrete zones of altered bedrock (mainly gneiss) associated with local selvages of quartz-carbonate veinlets. From one-third to one-half of the structures exposed at the surface are conspicuously mineralized as well as altered. The vein systems consist of narrow, tabular or splayed veins, often occurring as sets of parallel and offset veins. The veins thin and thicken abruptly along the structures in classic “pinch-and-swell” fashion with widths varying from a few centimetres up to a few metres. “Swells” formed in structural dilatant zones along the veins often forming mineralized “shoots”. At the SGX mine, these shoots range from 30 m to ........


Mining Methods

  • Resue mining
  • Shrinkage stoping
  • Room-and-pillar


Summary:

The Ying Mining District has been intermittently mined over many years by small-scale, local miners. Silvercorp commenced mining at its Ying property (SGX mine) in April 2006. Its current mining activities continue to be focused at the SGX mine, but now also include the HZG (a satellite deposit to SGX), HPG, TLP, LME, LMW, and DCG mines. Underground access to each of the mines in the steeply-sloped, mountainous district is via adits at various elevations, inclined haulageways, shaft / internal shafts (winzes), and declines (ramps). The mines are developed using trackless equipment – 20 t trucks and single-boom jumbos; small, conventional tracked equipment – electric / diesel locomotives, rail cars, electric rocker shovels; and pneumatic hand-held drills. Part of the TLP, SGX, LME, LMW, HZG, HPG, and DCG mines still use small tricycle trucks with a payload of up to three tonnes each for hauling ore to the surface. In the Ying district, mine trucks are used in all the ramp areas for hauling ore and waste to the surface. These trucks meet the Chinese mine safety requirements. Excluding the ramp and tricycle areas, other mine sections use rail cars for hauling ore and waste to the surface. The global extraction sequence is top-down between levels, and generally outwards from the central shaft or main access location. The stope extraction sequence is bottom-up, with shrinkage and resuing being the main mining methods. Jacklegs are used in stope blast drilling. In-stope ore han ........
