Highlights of the drill results included 716 grams per ton (g/t) silver equivalent (AgEq) over 6.8 metres (191 g/t silver, 1.9 g/t gold, 7.1% lead and 3.4% zinc) as well as 1,687 g/t AgEq over 0.4 metres (1,559 g/t silver, 0.5 g/t gold, 1.4% lead and 1.1% zinc). Another intercept returned 12.6 metres at 1.7 g/t gold, 17 g/t silver and 0.7% zinc.
The results reveal the presence of wide zones of gold mineralization as well as “attractive” near-surface polymetallic mineralization, GR Silver told shareholders.

The data from the 14 holes released also defines a mineralized strike length of up to 700 metres with field evidence and underground mapping pointing to further continuity along strike and down dip, the firm added.

CEO Marcio Fonseca said the results confirm continuity of the Plomosas Mine Area mineralized system, extending at least 700 metres along strike to the northwest.
“(Our) recent surface exploration work has provided evidence that the mineralized footprint extends beyond the existing drilled areas,” Fonseca said in a statement. “The definition of silver-gold rich mineralized zones close to the surface represents potential for the delineation of shallow resources at the Plomosas Mine Area".
GR Silver has earmarked the zone of mineralized veins and hydrothermal breccias for an upcoming shallow diamond core drill program. The firm believes that the Plomosas Mine Area is part of a much larger low sulphidation epithermal system thanks to field evidence along one kilometre of strike length, where only 400 metres of that strike has previously been drilled.
