Abstract

Gravel sampling was completed at a density of 1:20km squared totalling 60 samples, consisting of 20-25 kg of 0.2mm material. Only one sample returned possible kimberlitic indicator minerals (4 x 0.4mm chromites), which upon SEM examination were shown to be of non kimberlitic origin. Stream sediment sampling was completed at a density of 1:1.5km squared totalling 277 samples. This outlined several low order base metal (Cu Zn Mn) anomalies. With copper dominated anomalies occurring in the SE of the Ooramina Ranges, with the remaining anomalies on the limbs of the Ross River and Fergusson Synclines-anomalism appears to be associated with elevated background readings for Arumbera, Todd River, and Loves Creek Formations. 40 rock chip samples failed to highlight any elevated base metal values. Elevated Fe and Mn (Max 23.6 % and 17.6% respectively) correlate with elevated Cu and Zn, suggesting scavenging.
