GR Silver Mining Ltd (CVE:GRSL) (OTCQB:GRLSF) (FRA:GPE) has defined a new mineralized zone at the San Juan area of its flagship Plomosas silver project in Mexico.
The new zone, called the Yecora Vein, includes results from a 2020 drilling program as well as a reinterpretation of historical drill results from the area, according to the company.
Results from 29 shallow core drill holes revealed a zone measuring around 500 metres along strike and open in both directions that includes polymetallic, epithermal vein-style mineralization from two to five metres wide.

Highlights of the results reported from San Juan include 5.5 metres at 332 grams per ton (g/t) silver equivalent (AgEq), including 1.5 metres at 1,112 g/t AgEq, and 19 metres at 297 AgEq.
The proximity of the drill results to the surface, in combination with favourable topography, gives the Vancouver-based junior an “immediate target” for additional drilling along strike and down dip, GR Silver said in a statement.
The results from the Yecora Vein together with recent 3D modelling of ground IP and airborne magnetic geophysical data gives GR Silver confidence to define a larger epithermal system at San Juan, CEO Marcio Fonseca told shareholders.
“Since the March 2020 acquisition of the Plomosas project, the company has expanded the strike length of the San Juan system from its original 400 metres to approximately 2 kilometres, and has demonstrated the presence of at least six mineralized veins,” Fonseca said in a statement.
“Our ongoing surface drilling program, together with validation of extensive historic drilling data, is providing strong evidence that the mineralized footprint extends beyond the previously drilled areas.”
GR Silver has increased the scale of drilling at Plomosas from 4,500 metres to 11,900 metres. There are currently five drills active on site as part of a resource expansion and discovery program.
The firm believes that the San Juan Area represents a large, low sulphidation epithermal system.
