Summary

Silvercorp Metals Inc. has reported updated Mineral Reserves and Resources for its GC Mine, effective December 31, 2025, prepared in accordance with NI 43-101. The update shows a 59% increase in Measured and Indicated resource tonnes and a 25% increase in Proven and Probable reserve tonnes. However, these increases were accompanied by significant grade dilution across all commodities and categories, leading to a decrease in contained metal for reserves and inferred resources.

Reasoning: The updated resource and reserve estimates show a mixed picture. While there was significant tonnage growth in M&I resources and reserves, this was accompanied by substantial grade dilution across all commodities and categories. This resulted in a decline in contained metal for reserves and inferred resources, and only a moderate increase for M&I resources, suggesting dilutive growth. The grades for lead and zinc are marginal, and contained lead is below the weak threshold for contained metal scale.

Positive factors

  • Measured and Indicated resource tonnage increased by 59%, leading to a 23-25% increase in contained metal for silver, lead, and zinc.
  • Proven and Probable reserve tonnage increased by 25%.
  • The resource and reserve estimates are NI 43-101 compliant and signed off by Qualified Persons.
  • Cut-off grades for both resources and reserves are clearly disclosed.

Negative factors

  • Average grades for Measured and Indicated resources decreased significantly (21-23% for Ag, Pb, Zn).
  • Average grades for Proven and Probable reserves decreased significantly (22-25% for Ag, Pb, Zn).
  • Contained metal for Proven and Probable reserves decreased by 2-7% despite tonnage growth, indicating dilutive growth.
  • Contained metal for Inferred resources decreased substantially (32-47% for Ag, Pb, Zn) alongside a 23% tonnage decrease.
  • The contained lead in the Measured and Indicated resource (167 kt) is below the weak threshold of 200 kt, indicating a very small scale for lead.

Classification and evidence

Resource Updateneutral

Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: The document reports an 'updated Technical Report' with 'updated Mineral Reserves and Resources'.

Evidence · text

“SILVERCORP REPORTS UPDATED MINERAL RESERVES AND RESOURCES AT THE GC MINE”

NI 43-101 Compliantpositive

Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.

Why it applies: The technical report was 'prepared in accordance with National Instrument 43-101'.

Evidence · text

“prepared in accordance with National Instrument 43-101 ("NI 43-101")”

QP/CP Signedpositive

Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.

Why it applies: The estimates were 'reviewed by independent Qualified Person, Ms. Yanfang Zhao, MAIG, MAusIMM' and 'reviewed by independent Qualified Person, Falong Hu, FAusIMM (CP)'.

Evidence · text

“reviewed by independent Qualified Person, Ms. Yanfang Zhao, MAIG, MAusIMM, of SRK Consulting (China) Ltd., who takes responsibility for these estimates.”

Cut-off Disclosedpositive

Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The document states 'Mineral Resources are reported above cut-offs' and 'reported at a cut-off grade of 80 g/t AgEq' for resources, and '100 g/t AgEq and 130 g/t AgEq COG was applied to shrinkage and resuing type stopes' for reserves.

Evidence · text

“Mineral Resources are reported above cut-offs after applying a minimum practical extraction width of 0.4 m. Cut-off grades are based on in situ values in silver equivalent (AgEq) terms in grams per tonne”

Tonnage Growthpositive

Significant tonnage increase (≥15%) vs prior estimate with grade maintained or improved.

Why it applies: Measured and Indicated Resource tonnes increased by 59% and Proven and Probable Mineral Reserves tonnes increased by 25%.

Evidence · text

“Measured and Indicated Resource tonnes have increased by 59%”

Contained Metal Growthpositive

True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The net result in the Measured and Indicated categories has been an increase in the contained Ag, Pb and Zn of 23%, 24% and 25%, respectively.

Evidence · text

“net result in the Measured and Indicated categories has been an increase in the contained Ag, Pb and Zn of 23%, 24% and 25%, respectively.”

Grade Declinenegative

Average grade dropped >5% vs prior estimate — deposit economics worsening. May indicate high-grading in early drilling.

Why it applies: Measured and Indicated grades decreased by 21-23% for Ag, Pb, and Zn, and total Mineral Reserve grades decreased by 22-25% for Ag, Pb, and Zn.

Evidence · text

“Measured and Indicated grades decreasing by 23%, 23% and 21% for Ag, Pb and Zn, respectively.”

Contained Metal Declinenegative

Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.

Why it applies: Total GC Mineral Reserve metal content for Ag, Pb and Zn decreased by 4%, 7%, and 2% respectively, and Inferred contained metal decreased by 32-47%.

Evidence · text

“Decrease in total GC Mineral Reserve metal content for Ag, Pb and Zn of 4%, 7%.and 2% respectively.”

Dilutive Growthnegative

Tonnage increased but contained metal flat or down — likely from lower cut-off grade, not geological expansion.

Why it applies: Reserve tonnage increased by 25% but contained metal decreased by 2-7%, indicating that the tonnage growth was dilutive.

Evidence · text

“25% increase in total Proven and Probable Mineral Reserves tonnes. The changes in total contained metal for Ag, Pb, and Zn are -4%, -7%, and -2% respectively.”

Inferred Resourcenegative

Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The document reports 'Estimated Inferred Resources of 7.36 Mt'.

Evidence · text

“Estimated Inferred Resources of 7.36 Mt”

Underground Miningneutral · Story-specific tag

No canonical definition is currently available.

Why it applies: The document describes 'current stoping practices will continue to be predominant at the GC Mine, namely cut and fill resuing, overhand cut and fill stoping... and shrinkage stoping'.

Evidence · text

“current stoping practices will continue to be predominant at the GC Mine, namely cut and fill resuing, overhand cut and fill stoping ("OCAF"), and shrinkage stoping”

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
