Victory Metals (ASX:VTM) said metallurgical results at the North Stanmore heavy rare earth project in Western Australia showed that around 80% of rare earths leached in 30 minutes compared to the four-hour assumption used in the scoping study, which is expected to reduce the project's capital expenditure and operational expenditure through a smaller leach circuit, according to a Thursday Australian bourse filing.

Further testing at a 15-minute interval is underway. The firm plans to complete additional kinetic optimization testwork as well as conduct engineering updates to incorporate revised leach parameters.

It also completed baseline environmental and biological studies at the project.
