Why it may matterVerify against the original reporting
The material uplift in Measured+Indicated resources and reserves, plus a higher production profile and meaningful NPV, creates fundamental upside. Similar past NI 43-101 updates have driven short- to intermediate-term stock moves if investors view it as de-risking and long-life asset optionality; however, the impact depends on tailings approvals and execution risk.

The resource base expanded 59% to 18.3 Mt with higher production plans through 2041, supported by a post-tax NPV5 of $101.4M and Silvercorp’s 99% stake.
