The Challenger gold deposit lies in central South Australia, 750km NW of Adelaide (Figure. 1). Mineralisation is hosted by meta-sedimentary rocks of the Christie gneiss within the Mulgathing complex, a sequence of metamorphosed Neo-Archaen, rocks that occupies the north-western corner of the Gawler Craton (Daly et al. 1998). The deposit was ...

The mine remained an undeveloped operation for years after Dominion discovered it in 1995. In December 2000, Dominion purchased the 50% stake held by Resolute and began a feasibility study on the development of an open-cut mining operation. The study was completed in 2001. Shortly after that, the company began constru…

The second metasedimentary sample 1562450 is from a predominantly clastic sequence of the Christie Gneiss, outcropping northwest of Challenger Mine (Fig. 3 c), in which metapsammitic to metapelitic units are interlayered at a variety of scales (Fig. 3 d). Garnet and biotite are common metamorphic minerals and leucosomes are a common product of ...

Progressive reintegration of silicate melt into the highly restitic proximal gneiss bulk composition, using mineral equilibrium modelling in the system NCKFMASHTO, indicates that hydrothermal alteration stabilized a higher proportion of hydrous minerals leading to increased fertility and thus melting in the proximal gneiss.

Gneiss (pronounced "Nice") is an orangeish-tan rock that spawns in ores between Y=5 and Y=112. It can be crafted into a block literally called Gneiss. The ore is affected by the Fortune enchantment. Oddly enough, Gneiss is a very dangerous material once crafted into a block or found otherwise. When broken, it drops itself, but also spawns a lava source in the space it …

are important in the NW, where Challenger is located. The shears act as local conduits for granitoid intrusion. The host to the mineralization is the Christie Gneiss which is a garnet-rich paragneiss of plagioclase, perthitic K-feldspar, quartz, cordierite, garnet and biotite with minor graphite and Fe-Ti oxides (Bonwick, 1997) and forms part ...

The Challenger gold deposit in South Australia is hosted by pelitic migmatites that underwent peak metamorphism at ∼7.5 ± 1.5 kbars and at least 800°C. Nd model ages suggest a protolith age of ...

The Challenger area consists predominantly of the Christie Gneiss, which is a compositionally layered granulite facies metasediment. The most prominent and persistent type of outcrop in the region is BIF, which, in places, has been complexly folded and oxidised to haematite–goethite gneiss. The BIF has a typical composition

The Challenger mine is a gold mine in the Far North of South Australia, 165 km west of the Stuart Highway and 740 km north-west of Adelaide.It was operated by Dominion, Kingsgate and then WPG Resources. The mine is now on Care and Maintenance. The deposit was named by the geologist who discovered it (David Edgecombe), after his dog.
