Ownership: The Reef property consists of 99 unpatented mining claims owned by RenGold.
History: Historic exploration in the Reef area focused on surface exposures of the Joana Limestone, a known host for Carlin-type gold mineralization at the former Easy Junior (Nighthawk Ridge) mine located approximately 5 miles to the southeast. Midway Gold Corp.'s Pan gold deposit mineralization lies to the north in rocks of the Pilot Shale and Devils Gate Limestone, units which also underlie the Reef area. Previous shallow reverse circulation drilling stopped short of testing these units. Midway has completed a Preliminary Economic Assessment on the Pan deposit and is conducting development drilling. The proximity of this evolving project and infrastructure greatly increases the likelihood of economic success on Reef.
Geology: The claim block spans the crest and western limb of a broad anticline in middle Paleozoic rocks. The anticline plunges gently southward exposing Devonian Devils Gate Limestone at its core within 1000 feet north of the northeastern corner of the claim block. The Mississippian-Devonian Pilot Shale, Mississippian Joanna Limestone, and Mississippian Chainman Shale lie in-succession above the Devils Gate in exposures of the western limb of the anticline. The western part of the claim block covers the eastern margin of a Cretaceous quartz diorite stock that has intruded the Paleozoic sequence. Conglomerates and sandstone of the Mississippian Diamond Peak Formation overlie the Chainman and older units at the western edge of the claim block. Rhyolite dikes or sills cut the Paleozoic sequence locally within the claim block. Tertiary flows and tuffs cover most of the eastern limb of the anticline.
Elevated gold, arsenic, antimony, and mercury in rock chip samples are associated with silicification and sanding of carbonate rocks in the Paleozoic sequence. Zones of jasperoid occur along bedding in the Joanna and along breccias developed adjacent to faults. Alteration extends locally into the underlying Pilot Shale and the overlying Chainman Shale. Silicification occurs also in the Devils Gate Limestone.
On the Reef claims, the inactive, historic Black Horse mine hosts surface mineralization within the Joana Limestone that has returned up to 5.2 g/t gold and 716 g/t silver (Golden Dory Press Release Aug. 17, 2010).
