Silvercorp Reports Positive Exploration Results from the TLP and LME Mines at the Ying Mining District

VANCOUVER, British Columbia, Nov. 04, 2019 (GLOBE NEWSWIRE) -- Silvercorp Metals Inc. ("Silvercorpa?? or the a??Companya??) (TSX/NYSE American: SVM) is pleased to report the results of its 2018-2019 exploration programs at the TLP and LME mines, Ying Mining District, Henan Province, China. AExploration drilling is ongoing at the TLP and LME mines, and all other mines at the Ying Mining District.
From April 1, 2018 to September 30, 2019, Silvercorp continued the extensive exploration programs at the TLP and LME mines and completed 37,212 metres (a??ma??) of diamond drilling with six underground rigs from current production levels, and 33,004m of exploration tunneling between elevation levels 500m and 1,070m. AResults from the drilling program extended the major mineralized vein structures along strike and downdip, and exploration tunneling exposed high grade mineralized zones within major production vein structures. AEight new mineralized veins were discovered in the TLP mine during this period. AAmong them, veins T31W3, T26, T26E, T39E, T39E2 and T17E indicate the increasing importance of the NNW and NS striking veins. AThe drilling results from veins LM5, LM5E and LM4 at the LME mine extended the high-grade mineralized zones to at least the 260m level.Highlights of selected mineralized zones exposed in the drift tunnels:

Drift Tunnel PD890-T5E1_1-890-31NYM exposed mineralization 15m long and 0.44m wide (true width) grading 1,784 grams per tonne (a??g/ta??) silver (a??Aga??), 9.55% lead (a??Pba??) and 0.81% zinc (a??Zna??) within vein structure T31W3 on the 890m level at the TLP mine;
A



Drift Tunnel PD1050-T26-1050-A4NYM exposed mineralization 25m long and 1.11m wide (true width) grading 716 g/t Ag, 9.05% Pb and 0.13% Zn within vein structure T26 on the 1050m level at the TLP mine;
A



Drift Tunnel PD930-T14E-930-A0SYM exposed mineralization 60m long and 1.66m wide (true width) grading 430 g/t Ag, 5.05% Pb and 0.39% Zn within vein structure T14E on the 930m level at the TLP mine;
A



Drift Tunnel PD820-T16-600-1SYM exposed mineralization 80m long and 1.04m wide (true width) grading 719 g/t Ag, 5.19% Pb and 0.92% Zn within vein structure T16 on the 600m level at the TLP mine; and
A



Drift Tunnel PD900-LM18E1-915-52NYM exposed mineralization 60m long and 0.47m wide (true width) grading 1,469 g/t Ag, 2.38% Pb and 0.28% Zn within vein structure LM18E1 on the 915m level at the LME mine.

The exploration tunneling from April 1, 2018 to September 30, 2019 at the TLP and LME mines, comprising drifting, crosscutting and raising, was driven along and across major mineralized vein structures to upgrade the drill defined mineral resources and test for new parallel and splay structures, and is summarized in the following table:

[1] Mineralization is defined by silver equivalent value (AgEq) greater than or equal to 120 g/t at the TLP mine and 125 g/t at the LME mine. (Formulae used for AgEq calculation: TLP=36.75*Pb%+Ag g/t; LME=39.019*Pb%+Ag g/t)
