GR Silver Mining Ltd (CVE:GRSL) (OTCQB:GLYXF) has reported additional high-grade drill results at its Plomosas Silver Project in Sinaloa, Mexico.
The company said the results are located in the San Juan area, one of six priority areas, that indicate continuity of the high-grade silver-gold mineralization on a step-out section, 100 miles north of drill holes previously reported.
The new drill results included an intersection of 2.7 metres (m) at 1,304 grams per ton (g/t) silver equivalent and 3.6m at 675 g/t silver equivalent, according to GR Silver.

"The step-out drilling results along the strike of the San Juan mineralized system have confirmed the presence of a high-grade footprint related to the breccia-hosted Pb-Zn-Ag-Au mineralization and the sub-vertical fault-hosted, low sulphidation epithermal Ag-Au vein-breccia systems,” GR Silver CEO Marcio Fonseca said in a statement.
"We have validated the extent of the San Juan trend on surface to span over 500 m along strike. Additionally, we have validated approximately 30% of the San Juan drill database, with reviews continuing. Based on our success in defining multiple mineralized systems and confirming high-grade mineralization along strike, we believe that there is upside potential for further positive results on the remaining drill holes still to be released," he added.
The existing drill holes for the Plomosas Project were generated by drill campaigns completed by Grupo Mexico between 1982-2000 and First Majestic Silver Corp (NYSE:AG) between 2016-2018 and form an extensive database which GR Silver is consolidating and validating.
GR Silver said the primary objective of Grupo Mexico was the discovery of lead and zinc mineralization as potential feed for their historical flotation plant operations nearby. First Majestic drilled the Plomosas Mine Area aiming to define new mineralized zones down-dip and along strike from the surface and underground sites.
Wherever assay intervals are identified as missing within the drill hole database, the relevant drill holes will be re-examined, sampled, and assayed using the remaining core to complete the sequence of results, the company added.
GR Silver also said it continuing with its review and validation of more than 500 surface and underground drill holes on all six zones, aiming to confirm additional multiple vein systems hosted in a set of regional high angle fault zones and shallow dipping younger regional faults.
The company is also evaluating all exploration information related to 16 additional epithermal veins identified on the Plomosas Project property to define new drilling targets.
