Tivan (ASX:TVN) said geophysical surveys across the Molyhil tungsten project and Sandover fluorite project in the Northern Territory identified several targets for follow-up exploration, according to a Friday Australian bourse filing.

A high-resolution magnetic and radiometric survey was completed across Molyhil to identify new tungsten targets and refine known targets, as well as fluorite vein systems. The survey was also conducted across Sandover, including known fluorite vein systems and a manganese-barite gossan named Walshy's Wall. A high-resolution ground gravity survey was also completed across Molyhil.

Tivan is working with Mitre Geophysics to process and interpret the survey data.

Its shares fell 3% in recent trading on Friday.
