Guyana Goldfields (GUY-T) continues to intersect good lengths of low-grade gold mineralization on its Aurora gold property in western Guyana, as it attempts to drill off a resource at the Rory’s Knoll prospect.
Four deep holes on Rory’s Knoll, all directionally drilled to construct a longitudinal section of the gold deposit, cut wide zones of mineralization including some local high-grade intervals. One deep hole, RKD-62-DV2R, was wedged off from an earlier hole. It intersected 124.9 metres that averaged 2.64 grams gold per tonne, at a vertical depth around 1,170 metres.
A shallower wedge from the same primary hole, RKD-64, intersected 5 metres grading 4.06 grams gold per tonne, followed by 52 metres grading 2.61 grams and then by 195 metres grading 1.35 grams per tonne. The mineralized intersections were around 980 metres vertical depth.
Two other holes wedged off hole RKD-60 tested areas between 600 and 800 metres below surface. RKD-60DV4R cut 140.5 metres grading 3.41 grams gold per tonne and RKD-60DV5R cut 70 metres grading 2.22 grams per tonne before drilling had to be stopped.
The mineralization at Rory’s Knoll mainly occurs at the contact of a tonalite intrusion.
Three holes tested shallower mineralization on a nearby prospect, East Walcott Hill, and all intersected multiple zones of gold mineralization in quartz veins and breccia. Grades were mainly between 1 gram and 4.3 grams per tonne, but in the last of the three holes, EWD-19, a 45.5-metre interval ran 7.2 grams gold per tonne and a deeper 18.6-metre interval averaged 10.6 grams per tonne.
