Big River (continued) Figure 9. Interpreted Big River shoots. Mapping to the south of the Big River mine has confirmed that a large broad Sunderland Anticline extends at least 5kms from the Big River mine to St George and is open to the north and south (Figure 9). This anticline is largely obscured by thin glacial till but there is sufficient basement outcrop in creek beds to map this structure. The main reef track that runs through the St George and Big River South mines is parallel and 250m to the west of the anticline hinge and appears to link into the Big River mine. These structures are prime target areas for Big River mine style mineralisation. Soil geochemistry has now been completed for over 5kms fromBig River North to around 2kms south of St George. The arsenic and gold soil geochemistry shows large anomalies at Big River mine and a 3km long anomaly fromGolden Hill to south of St George, where it is cut-off by the granite intrusion (Figures 10 and 11).
