Abstract: In 1968, Perenti copper prospect was discovered by Central Pacific Minerals N.L, about 240km NE of Alice Springs. An extensive programme of geochemical sampling and geological mapping was carried out prior to the drilling of three angle diamond holes DDNT-12-1, DDNT-12-2 and DDNT-12-3 in late 1969. Drill core was re-examined to determine:
1) Whether existing detailed logging properly reflects the geology of the core;
2) Whether the geochemical values recorded seem reasonable given the observed mineralization in core;
3) Whether the style of mineralization could be re-interpreted in the light of advances in understanding over the past 30 years, particularly in the light of the IOCG models.
There had been some confusion in the labelling and storage of core and/or the preparation of summary reports. In general where there is confidence that the core described in logs is correctly correlated with the actual hole, the core descriptions are very detailed and quite acceptable as being a trim and full record of lithologies intersected with some minor reservations in relating to an overestimation of hematite content. The same can be said where chemical analyses given can be compared with remnants of core i.e. analyses appear to properly reflect mineralization. No guarantees can be given about the precision of analyses in the late 60's early 70s however, but it is believed they will generally reflect the levels of mineralization adequately.
