Annual report for ELs 7557, 7558 and 7559 Barrow Creek Project, NT, year ending 11-12-1993

Abstract

Work undertaken included a synthesis of available airborne geophysics, semi regional and prospect scale gravity surveys, soil sampling (EL7558-201 samples), auger drilling (99 holes totalling 339m-EL7557) and rock chip sampling (EL7558). Serendipity led to the discovery of the Mt Esther Prospect (EL7558) which in outcrop contains 2 small ironstones (max assay 1450ppm Cu, 1585ppm Bi and 0.89ppm Au). Regional geophysics indicate that these ironstones lie on a coincident magnetic and gravity high. Soil sampling undertaken show Cu-Bi + Au anomalism (max values 7ppb Au, 420ppm Cu and 275ppm Bi). The auger drill programme at Green Prospect (EL7557) returned gold values generally BLD, with a max assay of 3ppb Au. Though the results are disappointing the area is of interest due to a coincident gravity-magnetic high.
