Mount Ridley Mines (ASX:MRD) said a geophysical reinterpretation across the Mount Ridley project in Western Australia improved its understanding of the geological controls driving rare earth element and gallium mineralization and defined seven target zones at the project, according to a Tuesday Australian bourse filing.

The target zones collectively form a 33-kilometer-long, untested corridor. The highest priority area is a 12.8-kilometer-long series of targets, east of the blocks that host the existing gallium resource.
