Osiris Geology & Mineralization
The bedrock geology consists of a southward and westward younging sequence of Neoproterozoic to Cambrian slope-facies sedimentary rocks that are part of the Windermere Supergroup. Two distinct intrusive rock units have been identified in the Osiris area, known as the Osiris Gabbro, dated at 465.6 ± 4.4Ma, and the Conrad gabbroic dikes, dated at 74.4 ± 1Ma. Gold mineralization is preferentially hosted in carbonate rocks, particularly silty limestone.
The local structure is generally characterized by steep homoclinal bedding with monoclines and isolated macroscopic (hundreds of metres in scale or larger) folds. Carbonate units are folded on the mesoscopic and macroscopic scale with only minor development of any associated cleavage and without many smaller-scale folds. The Osiris area is cut by significant faults that strike generally east-west or southeast-northwest.
Gold mineralization at Osiris is typical of the Carlin type gold systems of Nevada. Mineralization occurs as replacement bodies with both structural and stratigraphic control. Deposits frequently occur along or near faults and fault zones, particularly where these zones cut favorable host carbonate rock. Deposits are intimately associated with host-rock alteration characterized by decarbonatization, argillization, silicification and sulphidation that results in the formation of gold-bearing arsenian pyrite. Deposits have elevated geochemical concentrations of Au-As-Sb-Hg-Tl.

Anubis Geology & Mineralization
The 13 km² Anubis Cluster is underlain by favourable mid-Paleozoic limestone, silty limestone, shales and calcareous siltstones that are cut by a network of regional scale faults. Two of these regional faults – the Anubis and Northern faults – are extensional features that are believed to be mineralizing fluid conduits. Smaller scale cross-cutting faults show strong evidence for hydrothermal alteration and are also potential areas for mineralizing fluid focus.
Mineralization in the Anubis Cluster shows characteristics consistent with Carlin-type gold mineralization, as do other targets along the Nadaleen Trend. The Anubis discovery outcrop consists of highly fractured, strongly folded, jasperoid altered and decarbonatized siltstone and shale. Extensive soil geochemical anomalies in the Anubis Cluster occur with well-developed hydrothermal clay alteration developed in proximity to the feeder fault systems. The large-scale pathfinder element geochemical footprint suggests a very large Carlin-type environment with a long-lived plumbing system.
