Report on Drill Core Assays from former EL 4421, Daly River Region, NT

Abstract

Exploration Licence No 4421 was located 22 km south of 'Tipperary' homestead, in the Daly River region of the Northern Territory. Two diamond drillholes, BCD-1 and BCD-2, were dilled for Mobil Energy Minerals Australia in late 1983, under an agreement with Suttons Motors (Darwin), holders of EL 4421 'Beeboom Crossing' (See Open File Report CR 84/251). Carpentaria Exploration Company Pty Ltd obtained half-core samples from selected intervals in these holes as part of an in-house study on the possibilities of gold mineralisation occurring in the Cambro-Ordovician sediments of the Daly River Basin. Mobil's report mentions trace gold in surface rocks from EL 4421, but only a few short lengths of core from their drillholes were assayed at that time. The cores of the two diamond holes were inspected at the NTGS Core Library at Winnellie, and intervals chosen for assay. Gold and arsenic were the only elements assayed by Carpentaria. After the first assay results were received, the pulps of the samples were returned from AMDEL NT, and some of these sent to a second laboratory (AAL at Pine Creek) for check assaying.
