Abstract

An airborne magnetic-radiometric survey was completed over the licences. Interpretation of the data revealed a number of low amplitude short wavelength dipolar anomalies. 4 of the anomalies were followed up by a helicopter supported magnetic survey. This was only successful for one of the anomalies, the remainder were recovered by ground magnetometry. 29 airborne magnetic anomalies were loam sampled. Results were generally negative. 1 sample returned 5 chromites regarded as non kimberlitic. 13 airborne magnetic anomalies were followed up by ground magnetics. Inversion indicated that anomalies due to a near surface source of limited depth extent. 1 rock chip sample was collected from anomaly OT5 returning an anomalous value for zinc (2650ppm Zn).
