Abstract
The country rock of the Coimadai antimony orebodies is Lower Ordovician slate and sandstone, with northerly strike and steep westerly dip. It is intruded by narrow east-west striking pre-mineral porphyry dykes, which dip north and are displaced by or in places form the walls of the lode channels. The antimony lodes are lenticular ore-shoots in fault zones which show signs of intense crushing and shearing, the shoots being usually associated with fault intersections or branches. The workings are divided into two sections: No. 1, Draper's, in which the lode system strikes north-northwest and dips 45-55 degrees west, and No. 2, Bondison's, where the strike is east-northeast and the dip 60 degrees to the north. In No. 1 section most of the ore above the adit level has been extracted, but possibly 400 tons of the 5% Sb, ore have been developed below the level, and prospects of further ore are good. Gold values are much higher in No. 2 than in No. 1 section, but few assay data are available with regard to either antimony or gold content.
