Relinquishment report 25 May 1989 Manton Dam Area.

Abstract

The area is predominantly underlain by slates and dololutites of the Lower Proterozoic Whites Formation and slates, siltstones and quartzites of the overlying Wildman Siltstone. Previous exploration in the l960s by the BMR was aimed at uranium and base metals. Subsequent work by Geopeko Ltd. in the early l980s concentrated on following up the BMR base metal anomalies. Five main lead geochemical anomalies were located in the region, one of which (L6) occurs along the projected northern strike extensions of the Woodcutters Pb-Zn-Ag Mine in the relinquished area. None of the previous exploration evaluated the area for gold mineralisation, and consequently this became the main target for further reconnaissance work. Exploration on EL4424 by the Woodcutters Joint Venture has mainly concentrated on areas not covered by this report. The small number of samples collected from the relinquished area resulted in no anomalous gold, although several anomalous lead and zinc values were obtained from known anomalous area. Further work comprised reflagging and extending the Woodcutters Mine baseline and surveying to enable accurate location control for future work and the pegging of mineral claims. 1) Previous exploration by the BMR and Geopeko Ltd. has adequately explored the area for base metals. 2) Five lead geochemical anomalies were located In the region by the BMR, one of which (L6) lies within the relinquished area. 3) The northern strike extensions of the Woodcutters type Pb-Zn-Ag mineralisation are inferred to pass through the relinquished area that is now covered by mineral claim applications. This area is considered to be highly prospective for Pb-Zn-Ag mineralisation. 4) Previous exploration has not tested the area for gold, and several possible targets have been Identified in poorly outcropping areas.
