Abstract
Geophysical surveys were conducted on several Iscor prospects in the<br>Postmasburg region with the objective to locate and delineate possible high grade<br>iron-ore deposits. The area is mainly covered by calcrete and the orebodies are<br>irregular shaped and confined to synclines and karst depressions in the<br>Campbellrand Subgroup. Several anomalies were located that could represent iron<br>ore deposits. These anomalies were interpreted and modelled to determine the<br>physical dimensions of the potential ore deposits. The project is currently in the<br>drilling phase to establish ore grade and reserves.
