Annual Report Horseshoe Creek year ending 30 January 1991.

Abstract

55 stream sediment samples were taken during a reconnaissance programme, recovering 2 diamonds, 3 microdiamonds and a chromite. Subsequently aeromagnetic data from the previous title holder in the area was acquired. 17 anomalies were identified within the licence area and 9 of these anomalies were targeted for follow up to locate the diamond-microdiamond source. Follow up included a helicopter borne magnetic survey. 2 of the anomalies were then covered by a ground magnetic survey (CA5 and CA8). Modelling suggested a shallow, narrow body of limited depth extent. Drilling essentially confirmed the model for CA8. 7 loam samples were taken over magnetic features. 1 returned a single microdiamond from magnetic anomaly CA5. 4 stream sediment samples from the NE Georgina Basin were analysed for base and precious metals. No anomalous values were returned. 17 stream sediment samples were collected from Carrara Range Inlier. 2 samples from adjacent creeks were anomalous in gold (75.3ppb Au and 21.4ppb Au). Those anomalous values were followed up by further geochemical sampling. No anomalous values were returned.

Structural features reported include: Carrara Range Inlier.
