Silver Range Resources
Aurora has performed a number of geophysical surveys on the Yandle property including Mag, HLEM, as well as mapping and propecting.
The Yandle property covers two NUMIN showings (Yandle and Aruat) which were explored by Comaplex Resources Ltd. (“Comaplex”) and Cumberland Resources Ltd. from the early 1990’s until 2002. Numerous historical grab samples grading up to 16 g/t Au were collected from a zone of arsenopyrite and pyrite bearing schist developed along the contact between Archean mafic and intermediate volcanic rocks. The zone is 4.5 kilometres long, up to 100 m wide, and is the most extensive alteration zone documented by Comaplex in this portion of the Ennadai Rankin Greenstone Belt. Best reported historical grab sample analyses along the contact zone were 25 g/t Au at Yandle and 59 g/t Au at Aruat. Comaplex completed airborne and ground geophysical surveys, and detailed prospecting and mapping over a wide area prior to drilling their portion of the zone in 2002. The 9 hole drill program initially targeted sulphide horizons in the overlying rhyolitic volcanics. These returned low gold values and Comaplex then switched their attention to the contact zone where they intersected 3 m @ 11 g/t Au. The property was subsequently optioned to Placer Dome who drilled at Yandle in 2003. A total of 12 drill holes (1,766 meters) were completed in the Yandle area with the only reported results being 1.25 m @ 17.5 g/t Au and 2.8 m @ 2.5 g/t Au from separate zones in a single hole. The Aruat Zone remains un-drilled.
