Teena Zn Prospect - New Insights for Geophysical Discovery of Shale-hosted Zinc Deposits
Darren Hunt 
(Senior Project Geophysicist - Teck)

Teena is a Paleoproterozoic stratiform Zn-Pb deposit located 8 kilometres west of the McArthur River Zn-Pb Mine, NT.  Higher grade mineralization was drilled by Teck in 2013, and represents the most significant SHMS-style discovery in Australia since the early 1990’s.  While the style of mineralization is similar to McArthur river (HYC) Mine, Teena lies beneath 600 to 1000m of siliciclastic and calcareous sediments and is completely blind.  Thus, the system gives the explorationist  valuable insights into the challenge of exploring for blind SHMS deposits, which often present as challenging targets for geophysical detection.  This talk will present physical properties data in the context of the mineralogy and stratigraphic host and discuss the geophysical methodologies applied to at Teena and the subsequent toolkit developed for the detection of deeply buried systems using Teena datasets as examples.
