WA1 Resources (ASX:WA1) said it completed proof-of-concept niobium oxide refining test work on unrefined concentrate from the Luni project in Western Australia during the September quarter, showing that the mineralization could produce higher-value niobium products, according to a Thursday Australian bourse filing.
Three drill rigs are operating at the project in order to support an updated mineral resource estimate, which is planned for 2026.
The company's shares shed about 1% in recent Thursday trade.
