These additional results confirm the presence of high-grade gold-silver mineralization in the Plomosas mine area, one of six identified priority areas, and come from un-mined zones.
Highlight assays included 1.8 metres (m) at 30.6 grams per ton (g/t) gold and 118 g/t silver, which included an intersection of 0.6 m at 86 g/t gold and 36 g/t silver.
With confirmation of new high-grade gold-silver zones hosted in subvertical faults, 100 metres along strike from the previously released cross-section, the firm said it saw potential for multiple high-grade mineralized veins, which could be used for a future resource.
"These results confirm multiple mineralization styles at the Plomosas Project, outside of the previously mined polymetallic high-grade Pb-Zn-Ag-Au breccia that was typically hosted in shallow-dipping regional faults," GR Silver CEO Marcio Fonseca said in a statement.
"GR Silver Mining is the first company to fully integrate and place all data in a 3D model allowing interpretation of a wide footprint of high-grade multiple veins. This modelling allows us to plan future expansion drilling and resource estimation. Our investigations of the extensive unreported drill database covering the Plomosas Mine Area continue to support a model with potential for mineralization not only hosted within a single high-grade structure but within multiple cross-cutting high-grade veins," he added.
Earlier in May, GR reported high-grade drill results from the San Juan area that indicated continuity of the high-grade silver-gold mineralization on a step-out section, 100 miles north of drill holes previously reported. Results included 2.7m at 1,304 g/t silver equivalent and 3.6m at 675 g/t silver equivalent.
And on April 23, the firm reported more assays from the Plomosas mine area, including an intersection of 1.7m at 26.9 g/t gold, 44 g/t silver, and 3m at 11.9 g/t gold and 22 g/t silver.
GR Silver Mining is focused on key assets in Mexico which lie on the eastern edge of the well-known Rosario mining district.
