Silvercorp Metals Update LME Mine in Ying Mining District inChina
Silvercorp Metals Inc has reported results from its 2021 exploration programs at the LME mine. Extensive exploration drilling and tunneling are ongoing at the LME mine, and all other mines at the Ying Mining District in Henan Province of China. From October 1, 2020 to May 31, 2021, 17,752 metres from a total of 113 diamond drill holes, including 98 underground holes and 15 surface holes, were completed at the LME mine. Assay results for 102 holes have been received, with 52 holes intercepting mineralization. Currently, seven rigs are drilling at the LME mine.
The diamond drilling programs at the LME mine targeted blocks of known silver-lead-zinc veins in the resource areas that were previously missed due to limited drilling or tunneling, changes in the strikes and dips, and/or pinch-swelling of the pay-zones in the veins. Since access tunnels are already in place, any discovered high-grade blocks can quickly be converted to reserves and mined.
The high-grade intercepts for this period are associated with parallel veins LM5, LM5E, LM5E1, LM5E2, M5W, and LM5W2. Other veins include LM4W, LM4W2, LM6 and its parallel veins LM6E, LM6E2, LM6W and LM6W1.
Step-out drilling at the LME mine also hit high-grade silver-lead-zinc mineralization, including veins LM61 and LM66 to the south and vein ML18E to the north. Hole ZKG20AT1704 confirmed that the north-south striking vein T17E at the TLP mine extended southward to the area between the TLP and LME mines. These discoveries confirm the potential of high-grade silver-lead mineralization extending beyond the defined resource area of the LME mine.
Highlights of high-grade intercepts of vein LM5, LM6 and their parallel veins at the LME mine:
