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 pr oject: the previous underground mining

operations, its processing cost, and 120% of the Co nsensus Price forecasts for the product element

as at January 2019.

Notes:

1. CIM Definition standards (2014) were used for reporting the Mineral Resources.

2. All data current to November 30, 2018.

3. Silvercorp owns 70% equity interest of BYP Au-Pb-Zn Project.

4. Pb Equivalent (PbEq) formulas used for equivalent grade is: PbEq= Pb + Zn*1.3069 + Au*2.1386.

5. Mineral Resources are reported on a dry, in-situ basis.

6. The overlapped areas were reported inside lead and zinc resource table based on PbEq cut-off.

7. Mineral Resources are reported at a 1.6 g/t Au cut- off and 3% Pb equivalent cut-off. Cut-off paramete rs

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$2,76 0/t, increased to 120% of prices from "Energy &

Metals Consensus Forecasts", to reflect long term p rice 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.

8. No mining license depth limit was applied for the Min eral Resource reporting. No mining license depth

limit was applied for the Mineral Resource reporting as the mining license update is still in progress.

9. The Mineral Resources referred to above have not be en subject to detailed economic analysis and

therefore have not been demonstrated to have actual economic viability.

10. It should be noted that for any SEC filings that th e SEC does not recognize resources, only reserves a nd 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, containin g approximately 418,000 ounces of gold. The

previous mining operation between 2011 and 2014 pro duced 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.
