This report summarises new petrological, geochemical and geochronological data on the Mount Webb Granite and the felsic volcanics of the Pollock Hills Formation of the western Amnta Block. The new data confirms that this magmatic system has many similarities to other granites in other Australian Proterozoic regions where hydrothermal Au-Cu deposits have been linked to a magmatic source (Pine Creek, Eastern Mount Isa Inlier, Tanami, etc.). The key significant data are the primary chemistry of the units, the alteration present in descriptions and evidence of hydrothermal interaction with the local country rocks.
