The Garden Well deposit lies in the DGB in the north-eastern part of the Archean Yilgarn Craton of Western Australia. The DGB is characterised by a strong N-S structural trend defined by major faults and shear zones, regional folds and granite batholiths.The geology of GWS UG consists of a sequence of folded sedimentary and volcanic rocks. The sequence can be differentiated into fine grained siltstones, lapilli and tuff volcaniclastics, sedimentary breccias, black shales, banded iron formation, chert, interbedded chert/shale and a footwall basalt unit. All of the units strike NNW at approximately 340-350o. Folding is tight and plunges approximately 20o to the SSE.Primary mineralisation is present as pyrite beds and veinlets within the western limb of the syncline, hosted by siderite-altered chert. Mineralisation at GDW is strongly controlled by lithological rock type.The maiden GWS UG MRE is estimated from the initial target zone at GWS and extends over 700m down plunge to a depth of 500 meters below natural surface.Gold is hosted in a moderate east to steeply dipping shear zone trending N-S. Gold mineralisation within chert, shale and BIF is associated with brecciated zones including elevated sulphides and quartz veins.
