HISTORY

Soil sampling located a second anomaly, A/90/18, 2km to the southwest of 4/0/78. Turam and selfpotential electrical geophysical surveys identified strong anomalies and resulted in the discovery of blind mineralisation estimated at 0.5Mt averaging 1.3% Cu. Mineralisation was traced up to 400m east and west of 4/0/78, and by 1965 an indicated and possible sulphide “ore reserve” was estimated of 943,100t averaging 3.06% Cu (2% Cu cutoff) plus an oxide “ore reserve” estimated at 272,000t averaging 1.5% Cu.

Between 1969 and 1972, ZAMEX completed additional diamond drilling and established a revised estimate of the “reserves” of 0.5Mt averaging 1.83% Cu in oxide mineralisation, and 3.3Mt averaging 2.12% Cu as sulphide mineralisation (1% Cu cutoff). A feasibility study on the deposits was completed, but no mining undertaken. The reasons for not proceeding to mining are not well documented, however RSG Global notes that options for metallurgical processing were limited relative 58 to modern processing, and that the timing of the study coincided with Government moves to nationalise the industry.

Between 1974 and 1975, Metalimex Mining Limited (Metalimex) completed limited diamond drilling at the 50/59 and 4/0/78 deposits. Revised “reserves” are reported, although the associated documentation is limited. Metalimex estimated oxide “reserves” at 0.7Mt averaging 1.87% Cu, and sulphide “reserves” of 2.36Mt averaging 2.96% Cu.
