The object of the survey is, primarily, to obtain a detailed preliminary assessment of the potential ore reserves of the field. Geological mapping and sampling of the major lode lines has been carried out in an attempt to determine the features which control ore deposition and to enable estimates to be prepared of the grade and tonnage of ore per vertical foot, which may be expected from these lode lines. The main emphasis of this work during the 1951 field season was on the major producing lines in what has been called the Southern Field, the Main Lode and part of the Stannum King lode. In addition to this programme, an area of approximately nine square miles was mapped in detail using aerial photographs. Approximately 1,000 square miles of the area surrounding Maranboy was mapped on a regional basis. The history of the field, general geology, and the geology of the individual lodes are discussed in this report.
