GR Silver Mining Ltd. to report drill results from the underground and surface drilling program in the Plomosas Mine Area, as well as sampling results from historic drilling, at its 100%-owned Plomosas Silver Project ("Plomosas Project") in Sinaloa, Mexico. The underground drilling program is targeting high-grade Ag-Au epithermal mineralization and bulk tonnage-style polymetallic mineralization in the Plomosas Mine Area, with the objective to delineate high margin precious and base metals mineralization for planned resource estimation. The results of the current drilling program, combined with systematic sampling of historic un-sampled drill core, at the Plomosas Mine Area, continue to delineate extensions of the mineralization previously drilled at level 775. They have also defined new mineralized zones laterally to previously mined areas with the presence of Au-rich epithermal veins. The drill results demonstrate continued success in the delineation of thick intercepts of Au-Ag-Pb-Zn-Cu mineralization, hosted in a series of hydrothermal breccias showing a strong relationship with structures and intrusions at shallow depth. These relationships indicate a potential association with a much larger epithermal system.
