VANCOUVER, British Columbia, Feb. 02, 2021 (GLOBE NEWSWIRE) -- Silvercorp Metals Inc. ("Silvercorp” or the “Company”) (TSX/NYSE American: SVM) announces its subsidiary, New Infini Silver Inc. (“New Infini”), has acquired a 100% interest in the La Yesca Silver Project (“La Yesca” or the “Project”), a silver-polymetallic, epithermal-type project located in Nayarit State, Mexico, approximately 100 kilometres (“km”) (185 km by road) northwest from Guadalajara, the second-largest city in Mexico.
La Yesca Silver Project
The Project covers an area of approximately 47.7 square km. Previous exploration activities between 2014 and 2018 included geological mapping, stream sediment and soil geochemical surveys, and widely-spaced drilling. A silver-lead-zinc soil geochemical anomaly of more than 500 metres (“m”) wide by 7.5 km long has been defined.
A total of 4,878 m3 in 106 trenches and surface strips and 7,649 m of diamond drilling in 25 widely-spaced drill holes has been completed to test the southern half of the 7.5 km long geochemical anomaly in Areas I, II, and III (see Figure 1). Fifty-six surface trenches and all of the 25 near vertically-drilled holes intersected mineralization, with 22 of the drill holes intersecting multiple mineralized intervals that have defined a northwest-trending 1,100 m long and 200 m wide mineralized zone in Area I, and a 3,500 m long and 400m wide zone in Areas II and III (see Figure 1).

As the 25 drill holes were widely spaced, near vertically-drilled and all intercepted mineralization, the previous owner interpreted the silver mineralization as sub-horizontal or low angle dipping zones (30-40 degrees) (See Section 372 in Figure 2). During on-site due diligence trips, Silvercorp geologists observed abundant evidence of steeply-dipping (70-85 degrees) and northwest (325 degree) extending structures/mineralization in trenches and outcrops, and observed almost all mineralization fractures in drill cores as near parallel to the cores, yielding further evidence that mineralization may have occurred as sub-vertical (See Section 372 in Figure 2).
This may imply that the mineralized intervals intercepted by these 25 widely-spaced drill holes are from multiple, different zones. A hole drilled 100 m away to test trench mineralization may have intercepted new zones rather than the mineralized zone revealed by the trenches. The future drill program will drill holes at a 45 degree angle to either validate this new model or as in-fill drilling for the low-angle interpretation. For example, trench BT742, with a 47.6 m interval grading 295 g/t Ag, 2.02% Pb, and 1.72% Zn, can be easily tested by a 45 degree drill hole, whether it is a low-angle or sub-vertical zone.

Silvercorp’s independent geological consultant also took core samples for re-assaying. The results shown in Table 2 have large variation, but all have significant, high silver grades.

Silvercorp Development Strategy
With successfully incubating New Pacific Metals Corp. and Whitehorse Gold Corp., Silvercorp intends to follow the same strategy and list New Infini as an independent public company, with a controlling interest, in the near future. This approach allows each company to operate independently on projects in different jurisdictions to reduce management risk and enables each company to pursue independent growth and capital allocation strategies while still maintaining Silvercorp’s interest, leadership, and core values. The success of this strategy is attributed to a disciplined and methodical approach in structuring and financing each new opportunity, and selecting and incentivizing dedicated and experienced executives and directors with a strong commitment to sustainable development and shared value creation.
Agreement Details and Share Structure
Future Exploration Plans
New Infini has assembled a team in Mexico to apply for drilling permits and to initiate a Phase I 10,000 m drilling program, which is expected to start in Q2 2021, once permits are received.
