Metallium (ASX:MTM) completed its third-quarter multi-unit flash joule heating operations campaign at its Texas Technology Campus involving three reactors operating with chlorine and platinum group metal-bearing catalytic converter material, according to a Thursday filing with the Australian bourse.

The 12-hour campaign, which showed controlled multi-unit operation under high-temperature reactive chlorination conditions, aims to generate data and samples for the next stage of development, the filing said.

Additionally, the company is advancing targeted feedstock testing and technical evaluation by collaborating with US Government agencies and selected industry participants, per the filing.
