Williamson, J.H. 1939 The geology of the Naseby subdivision, Central Otago. Wellington: Government Printer. New Zealand Geological Survey bulletin 39 141 p.
Abstract: This report describes the general and economic geology of the Maniototo depression, where in the early days several extensive alluvial diggings supported a considerable population. Some sluicing is still carried out, quartz lodes yield gold and scheelite, lignite is mined for local use, but the principal industries, which irrigation is likely to extend, are now pastoral and agricultural.
