Sunrise Energy Metals (ASX:SRL) continued to advance work streams required to support a final investment decision for the Syerston scandium project in New South Wales during the June quarter, including permitting and approvals, among others, according to a Thursday Australian bourse filing.

The basis of design, process design criteria, and process flow diagrams for the processing circuit and associated infrastructure at the project were advanced to near completion, the filing said.

The company is evaluating an expansion case for a potential additional 120 tonnes per year of scandium oxide production capacity, which would increase total potential production capacity to 180 tonnes per year, per the filing.

Sunrise Energy Metals' shares gained nearly 2% in recent trading on Thursday.
