Riverside Resources (CVE:RRI) reported Thursday high grade gold and silver trench results from its Penoles project in Durango, Mexico, with grades as high as 5 g/t gold and 500 g/t silver.
Highlights from trench results at the Jesus Maria target on the property include 22 metres at 1.08 g/t gold, 224 g/t silver, 2.5% lead and 1.7% zinc. The encouraging trench is above the target, the company said, and along strike from previous mining.
A second interval of 8.3 metres returned 1.68 g/t gold, 144 g/t silver, 2.4% lead and 2.2% zinc along strike, showing further surface mineralization that will be drill tested in the short term.
Riverside said that the work at Jesus Maria reported gold values ranging from less than 20 parts per billion to 5.1 g/t, and included nine samples each greater than 1.4 metres returning over 1 g/t gold.
Meanwhile, the silver values from the vein system at Jesus Maria were also positive, with results ranging from 7.8 g/t to 572 g/t, including 19 of the 34 samples returning more than 100 g/t silver.
In addition, the company said that trenching at the San Rafael zone indicated that higher grade mineralization could be present at depth.
"Mineralization at the surface can now be more adequately traced and the veins appear to be peaking out and showing the uppermost zones for Au-Ag-Pb-Zn-Cu drill targets," said president John-Mark Staude.
In March, Riverside signed a deal to option the 350 square kilometre Penoles project to Sierra Madre Developments. The two companies are jointly developing the property, and the latest results mark the beginning of a major exploration push at the site, in preparation for an upcoming drill program.
