VANCOUVER, British Columbia, May 08, 2019 (GLOBE NEWSWIRE) -- Silvercorp Metals Inc. (“Silvercorp” or the “Company”) (TSX / NYSE American: SVM) is pleased to report an updated National Instrument 43-101 Technical Report has been completed by RPMGlobal Asia Limited (“RPM”) on the Baiyunpu (“BYP”) gold-lead-zinc property in Hunan Province, People’s Republic of China (the “BYP NI 43-101 Technical Report”). The BYP NI 43-101 Technical Report, with an effective date of April 30, 2019, will be filed under the Company’s SEDAR profile at www.sedar.com within 45 days of this news release and on the Company’s website at www.silvercorp.ca.
The 2012 NI 43-101 report on the BYP property was based on data effective 2011. The current report is based on an additional 22 diamond drill holes and 1,099 metres of channel samples from tunnels.
The results of the mineral resource estimates for the three physically distinct areas (gold, lead & zinc, and overlap) of the BYP project, as extracted from the BYP NI 43-101 Technical Report prepared by RPM, are presented in Tables 1 and 2. A 1.6 g/t Au cut-off grade was used for the gold area in the report based on the following parameters for the project: the previous underground mining operations, its processing cost, and 120% of the Consensus Price forecasts for the product element as at January 2019.

- CIM Definition standards (2014) were used for reporting the Mineral Resources.
- All data current to November 30, 2018.
- Silvercorp owns 70% equity interest of BYP Au-Pb-Zn Project.
- Pb Equivalent (PbEq) formulas used for equivalent grade is: PbEq= Pb + Zn*1.3069 + Au*2.1386.
- Mineral Resources are reported on a dry, in-situ basis.
- The overlapped areas were reported inside lead and zinc resource table based on PbEq cut-off.
- Mineral Resources are reported at a 1.6 g/t Au cut-off and 3% Pb equivalent cut-off. Cut-off parameters were selected based on an RPM internal cut-off calculator in which the gold price of USD$1,490 per ounce, Lead price of USD$2,280/t and Zinc price of USD$2,760/t, increased to 120% of prices from "Energy & Metals Consensus Forecasts", to reflect long term price movements were applied, and the mining cost of USD$35 per ton, processing cost of USD$13.3 per ton milled and processing recovery of 87.41% Au, 85.87% Pb and 92.71% Zn based on 2018 BYP development and utilization plan report were applied.
- No mining license depth limit was applied for the Mineral Resource reporting. No mining license depth limit was applied for the Mineral Resource reporting as the mining license update is still in progress.
- The Mineral Resources referred to above have not been subject to detailed economic analysis and therefore have not been demonstrated to have actual economic viability.
- It should be noted that for any SEC filings that the SEC does not recognize resources, only reserves and the resources stated above are classified as mineralized material with no value.
Mineral Resources estimated for the gold area include a total of 4.3 million tonnes grading 3.1 g/t Au in the Measured and Indicated categories, containing approximately 418,000 ounces of gold. The previous mining operation between 2011 and 2014 produced 221,000 tonnes of gold mineralized material at an average recovered grade of 3.56 g/t Au for approximately 25,335 ounces of recovered gold. Mineralization is open along strike and down dip for both the gold and lead-zinc areas.
