Final report for ELs Bull Creek (EL 7125), Calvert Hills (EL 7199) and Bluey Creek (EL 7200) Calvert Hills area, NT

Abstract

An airborne EM survey was completed in 1991 over these titles. In general the signal was consistent with resistant lithologies, though 4 targets were identified for follow up within EL7200. Ground follow up indicated little potential for a shale hosted base metal deposit in 3 of the targets. A conductor of limited aerial extent was identified at approximately 400m at the remaining target. 81 stream sediment, 158 soil and 37 rock chip samples were collected from these titles. Elevated Pb-Zn values were associated with elevated iron and manganese and interpreted to be result of scavenging.
