SILVERCORP REPORTS UPDATED MINERAL RESERVES AND RESOURCES AT THE GC MINE

Silvercorp’s resource growth at the GC mine extends mine life despite reserve metal dilution and modest net present value capping near-term upside.

Executive Summary

Silvercorp released an updated NI 43-101 Technical Report for the Gaocheng (GC) Mine, showing a 59% increase in Measured & Indicated Resource tonnes and a 23-25% increase in contained Ag, Pb, and Zn versus June 2024.
Proven and Probable Reserves increased 25% in tonnes, but contained metal declined 2-7% due to grade dilution and mining depletion.
The updated Life of Mine (LOM) plan projects a production ramp from ~345 ktpa in FY2026 to ~370 ktpa by FY2029, targeting ~0.7 Moz Ag annually.
Post-tax NPV5 is $101.4M at an 8% discount rate ($100.3M to Silvercorp at 99% interest).
Mine life is projected beyond 2044, contingent on completing a tailings storage facility (TSF) expansion prior to FY2043.
Resource cut-off is 80 g/t AgEq; reserve cut-offs are 100 g/t AgEq (shrinkage) and 130 g/t AgEq (resuing).
Forecast pricing used: $40/oz Ag, $2,300/t Pb, $3,220/t Zn for resources; $31/oz Ag, $2,000/t Pb, $2,800/t Zn for reserves.

Material Impact

The GC mine resource update is positive but routine. The 59% increase in M&I tonnes and 23-25% metal growth demonstrates successful exploration and infill drilling, extending the mine's economic life.
However, the 2-7% decline in contained reserve metal highlights the natural depletion curve and dilution inherent in underground shrinkage/resuing methods. This is a standard mining reality, not a surprise.
The NPV5 of $101.4M is modest relative to the company's overall portfolio and recent cash generation. It does not re-rate the business but provides a clear floor for the GC asset's valuation.
The stock's 26% decline from its May 2026 peak to $15.83 suggests the market has already discounted near-term execution risks (El Domo delays, cost creep, macro headwinds). This news is unlikely to trigger a significant re-rating on its own.
