Gossan Valley is hosted in the Golden Grove Formation. Similar to Gossan Hill, the mineralisation at the Gossan Valley deposit has locally replaced sub-massive to massive magnetite in what is traditionally seen as a chalcopyrite-dominant footwall for the Gossan Hill deposit. However, at Gossan Valley the mineralisation is a combination of sphalerite and chalcopyrite. At Gossan Valley, stringer chalcopyrite and pyrite also occur further in footwall sediments, and small lenses of sphalerite and chalcopyrite occur in the hangingwall to the main mineralised position. A number of post mineralisation dolerite intrusives crosscut the stratigraphy and mineralisation at the Gossan Valley Deposits in several generations and orientations. In turn, the dolerites are crosscut by later small rhyolite intrusions. The Gossan Valley deposits are made up of multiple lenses within a 3.4 kilometre portion of prospective stratigraphy, extending from Grassi in the south to Conteville in the north. Some of the lenses that make up the Gossan Valley and Grassi deposits are open down plunge. The Conteville deposit remains open down plunge.Each zone varies from 50m to 450m along strike, 40m to 400m down-dip and 3m to 10m in thickness.
