Royal Road Minerals Ltd (TSX-V:RYR, OTC:RRDMF, FRA:RLU) has started diamond drilling at Güíntar, the most advanced target within its Güíntar-Alemán-Margaritas (GAM) gold-copper-silver project in Antioquia, Colombia, the company said. The new drilling from Platform 20 will follow the interpreted mineralized system down-plunge and beneath the limits of previous drilling, testing down-dip extensions of mineralization found in holes GUI-DD-013 and GUI-DD-028. GUI-DD-013 intersected 131 meters at 1 g/t gold equivalent, including 57 meters at 1.4 g/t gold, 10.2 g/t silver and 0.6% copper.
GUI-DD-028 intersected 176 meters at 1.2 g/t gold equivalent, including 76 meters at 2.1 g/t gold, 7.9 g/t silver and 0.4% copper, and remained open at depth. Additional drilling from Platform 19 will test the width and continuity of mineralization across adjacent fault-bound structural blocks. Recent geological and structural mapping, underground sampling, drill-core resampling and three-dimensional modeling have advanced the company's understanding of the GAM system.
Gold-bearing pyrrhotite veins and disseminations are now recognized throughout GAM and are increasingly interpreted as a widespread late hydrothermal flooding event superimposed on an earlier porphyry gold-copper-silver system. A total of 21 selectively sampled pyrrhotite-bearing veins from historical drill core at Güíntar and Niverengo returned gold values ranging from 0.15 to 69.5 g/t, with a median grade of 1.17 g/t. At Algodona, recent underground sampling returned 36 meters at 2.14 g/t gold and 6.95 g/t silver, along with a second interval of 11 meters at 1.49 g/t gold.
At Niverengo, reprocessing of historical geophysics has defined a previously untested coincident chargeability and magnetic target. At Alemán, about 500 meters northwest of Güíntar, previous drilling intersected 64.5 meters at 1.1 g/t gold and 1.4 g/t silver, including 24 meters at 2.4 g/t gold and 2.7 g/t silver. Work is also continuing at Venadera and Margaritas.
Beyond GAM, Royal Road controls approximately 1,840 square kilometers of mineral titles and applications across its Colombian portfolio. Reconnaissance is underway in the Northern Block, including at Cangrejo, Ebéjico and La Merced, while the company is advancing engagement with government and communities in the Southern Block to progressively reopen highly prospective areas in Cauca and Nariño to systematic exploration. "Our objective at Güíntar is to advance the known system toward a maiden mineral resource while continuing to demonstrate the broader discovery potential of GAM," said Dr Tim Coughlin, Royal Road's CEO.
"Beyond GAM, we are advancing exploration across our Northern Block and, importantly, working toward renewed access to our gold and copper portfolio in southern Colombia, which we believe is of exceptional quality."
