AR currently hosts a reserve base of 40 years at a mining rate of 80 000 tons per annum and a resource base of similar size.
AR conducts its own mining through open cast free-dig operations. The positional efficiency between pit and plant at AR is excellent as a round trip is less than 2 kilometres. Run of Mine (ROM) ore is dumped in selected stockpile positions ready to be mixed as required by the process. A buffer supply of ROM is contained in these stockpiles. Mixing is done as demanded by chemical analysis requirements and fraction sizes required.
