In today’s report I dig beneath the headlines to point out the recent reversal of fortune of Silvercorp Metals’ (NYSE: SVM) key SGX mine that accounted for 74% of SVM’s total production the last three years. SVM has done its best to mask the abrupt decline in the SGX mine from investors. Nevertheless, it is now clear that the SGX mine has much lower silver resource estimates than SVM previously disclosed and much lower grades of ore recently produced.
