Geology
The northern part of the Abitibi greenstone belt, in which the Noyon Gold Project lies, consists of east-southeast striking mafic volcanic, pelitic sedimentary, iron formation and mafic to felsic volcaniclastic rock units. Dikes and sills of mafic to felsic composition are common. Regional structure is dominated by several major east-west striking deformation zones, which are intimately associated with gold mineralization.
The property is completely covered with glacial-till overburden, which averages approximately 25 metres in depth. Bedrock geology, based on data from the 344 drill holes, consists of interbedded clastic sedimentary rocks and mafic to felsic volcanic rocks that dip steeply to the south. Contacts are marked by shearing, which is the focus of gold mineralization and associated alteration. There are also numerous altered and mineralized tectonic breccia zones in the volcanic rocks. Major faults trend northwest, northeast and east-west.
Cyprus identified two types of gold mineralization, the "RJ" type, which is associated with silicified graphitic shear zones, and the "A zone" type, which occurs in semi-concordant zones of arsenopyrite within basalt units that are close to contacts with sedimentary rocks. The higher-grade segments of the auriferous zones appear to be in close proximity to the intersection of cross structures with the sheared basalt-sediment contacts.
