We present a new dataset from the Eagle exploration project, completed in 2009 on the lesser explored southeast slopes of Galena Hill in the Keno Hill silver camp. The Keno Hill silver camp is hosted in Neoproterozoic and Paleozoic sedimentary rocks of the Selwyn Basin that were subsequently intruded by the Cretaceous Tombstone Plutonic Suite. Although a genetic association is documented between the Tombstone plutons and Au-As mineralization regionally, the genesis and age of the Keno Ag-Pb-Zn mineralization remains poorly understood. Mineralization studied from the Eagle project area, while modally dominated by indium-rich sphalerite, was introduced in at least three distinct phases. A low-amplitude aeromagnetic high occurs at the southeast end of Galena Hill and is suggestive of a buried intrusion. Two new U-Pb age dates of ca. 93 Ma have been determined for aplite dykes, indicating the presence of Tombstone Suite intrusions within the Eagle property.
