   Geology
   The ore bodies in Pioneer are breccias with quartz cement, metasomatically altered rock and veins and zones of stockwork. The number of veins ranges from one per metre to in excess of one hundred per metre. The ore bodies are characterised by the absence of precise visually defined borders, which can be determined only as a result of testing. In some cases the borders of ore bodies are ore-controlling faults. The gold tends to be concentrated in the metasomatically altered rock and breccias in the hanging-wall. Grade varies from 2-3 g/t to various tens of grams per tonne. The maximum gold grade (105 –114.5 g/t) is located at the fault in the main structure together with an ore-shoot of north-easterly direction.
