Geological report No.1 on Northern Star Copper-Gold Prospect

Abstract

The Northern Star Copper-Gold prospect is located 26 miles north of Tennant Creek Northern Territory. Four large gossan bodies outcrop within an area 2,000 by 1, 200 feet. A gold ore-body has been worked out from one of these gossans which produced 14,000 tons of ore grading 9.3 dwts Au/ton before the mine closed down. A considerable amount of prospecting in the form of magnetic surveys, diamond drilling and geochemistry has been carried out by the B.M.R and three separate exploration companies. The resulting data from this prospecting has been collated and presents the following exploration targets; 1) A gold-copper prospect based on the extension of a gold intersection averaging 23.4 dwt Au/ton over a core length of 30 feet, core length at 908 feet vertical depth in hole No 15 and 2.43% Cu over 39 feet core length at 913 feet vertical depth in Role No 14, 2) A copper prospect based on a geochemically anomalous copper zone in lens No 2 with a potential of 5,000 tons per vertical foot, 3) A copper prospect based on results of two magnetic surveys. A programme of geophysics and drilling is recommended to carry out an initial test on these targets for an expenditure of ?12,000 over a period of about five months.
