Forrestania’s camp of nickel sulphide deposits is hosted by a sequence of ~2.9Ga meta-igneous and metasedimentary rocks that are part of the Forrestania Greenstone Belt (FGB) of the Youanmi Terrane of the Eastern Yilgarn Craton.Forrestania’s nickel deposits is the ‘Kambalda-style’ Type 1 and Type 2 models where nickel sulphides are interpreted to have accumulated in channelised komatiitic lava flows. Many of Forrestania’s deposits are often tectonically displaced from the original depositional locations and have been deformed and/or dismembered by one or more local and/or regional post-depositional tectonic events.The main deposit type is the komatiite hosted, disseminated to massive nickel sulphide deposits, which include the Flying Fox and Spotted Quoll deposits. The mineralisation occurs in association with the basal section of high MgO cumulate ultramafic rocks. The greenstone succession in the district also hosts several orogenic lode gold deposits, of which the Bounty Gold Mine is the largest example.Flying Fox depositThe deposit is mainly located along the traditional footwall of the basal ultramafic metasediment contact, which was the original locus for sulphide deposition from an overlying pile of komatiite flows. Subsequent metamorphism, deformation, and intrusion of granitoid sills have contributed to a complex setting, with mineralisation now occupying a possible shear zone. The Flying Fox deposit strikes at 30° and dips nominally 65° east.DimensionsThe strike length of the Flying Fox deposit varies considerably but is up to 750m in the T5 deposit. Distance from the top of T4 to the base of T5 is approximately 550m. The mean width of the deposit is 2.2m.
