BYP Mine

NEWONE2325555

Overview

BYP is located approximately 220 kilometres southwest of Changsha, the capital of Hunan Province, China.

 

Historically, the site operated a ~500 tonne-per-day, ramp-supported underground mine and a sulphide flotation plant. It produced lead, zinc, and gold-bearing pyrite concentrates, which were sold to local smelters within the province. Operations were suspended due to the need for significant capital upgrades and unfavourable market conditions at the time.

 

Silvercorp is currently advancing the permitting process for a new, gold-focused mining operation at the site.

Mining

The development of future gold operations can leverage existing production infrastructure, including the substantially completed 265 m long shaft/headframe with a hoisting capacity of 1,000 tpd

Mineral Resource Estimates

BYP Mineral Resources Estimate as of 30 June, 2024 (1.2 g/t Au and 2.2% ZnEq cut-off)

Picture6

Notes:

  1. The Statement of Estimates of Mineral Resources has been compiled under direction of Mr. Song Huang, who is a full-time employee of RPM and Member of the Australian Institute of Geoscientists and has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity that they have undertaken to qualify as a Qualified Person as defined in the CIM Standards of Disclosure.
  2. All Mineral Resources figures reported in the table above represent estimates based on drilling completed up to 30th June 2024. Mineral Resource estimates are not precise calculations, being dependent on the interpretation of limited information on the location, shape and continuity of the occurrence and on the available sampling results. The totals contained in the above table have been rounded to reflect the relative uncertainty of the estimate. Rounding may cause some computational discrepancies.
  3. Silvercorp holds a 70% equity interest of BYP project, the Statement of Mineral Resources is reported on a 100% basis and does not reflect the ownership status.
  4. Zn Equivalent (ZnEq) calculated using long term "Energy & Metals Consensus Forecasts" June 2024 average of USD$2,220/oz for Au, USD$2,370/t for Pb, USD$3,110/t for Zn (increasing 20% by prediction) and processing recovery of 87.41% Au, 85.87% Pb and 92.71% Zn based on 2018 BYP development and utilization plan report. Based on grades and contained metal for Au, Pb and Zn, it is assumed that all commodities have reasonable potential to be economically extractable. a. The formulas used for equivalent grade is: ZnEq= Zn + Pb*0.7058 + Au*2.1638 b. The formula used for Au ounces is: Au Oz = [Tonnage x Au grade (g/t)]/31.1035
  5. Mineral Resources are reported on a dry in-situ basis.
  6. Mineral Resources are reported at a 1.2 g/t Au cut-off or a 2.2% Zn equivalent cut-off. Cut-off parameters were selected based on an RPM internal cut-off calculator in which the gold price of USD$2,220 per ounce, Lead price of USD$2,370/t and Zinc price of USD$3,110/t, inflated by 120% of prices from "Energy & Metals Consensus Forecasts" to reflect long term price movements were applied, and the mining cost of USD$41 per tonne, processing cost of USD$16 per tonne milled and processing recovery of 87.41% Au, 85.87% Pb and 92.71% Zn.
  7. Mining license depth limit of “Above RL -220m” was applied for the Mineral Resource reporting.
  8. The Mineral Resources referred to above have not been subject to detailed economic analysis and therefore have not been demonstrated to have actual economic viability.

Geological Background

To date, 30 lead-zinc and 11 gold zones have been identified.

 

Lead and zinc zones occur as stratiform and lenticular bodies in Devonian carbonate rocks, which overlie the host gold sequence.

 

Gold zones occur as stratiform or lenticular bodies in fractured clastic rocks in the lower portion of the Middle Devonian sedimentary sequence. The distribution of gold mineralization is structurally controlled by two major NE-trending faults, F3 and F5. Eleven gold zones have been identified to date at elevations from 40 m to 300 m above sea level. Individual zones range from 50 m to 600 m in length and 2 m to 50 m in thickness.
