Kingsland Minerals Ltd (ASX: KNG) has commenced metallurgical test work to evaluate the potential for recovering rutile (TiO₂) and gallium (Ga₂O₃) as valuable by-products from its flagship Leliyn Graphite Project in the Northern Territory.
The company has engaged Independent Metallurgical Operations (IMO) in Perth to investigate rutile extraction through flotation testing, while CSIRO is undertaking advanced mineralogical analysis to determine how gallium is hosted within the ore. Early studies indicate gallium is likely associated with muscovite and potentially other micas, while rutile occurs within the graphite-rich schist zone.
Recent assay results support the by-product potential. Drill hole LEDD_08 returned 285m at 23.7ppm gallium oxide and 0.42% titanium dioxide. The three samples selected for metallurgical testing averaged up to 25.5ppm Ga₂O₃ and 0.61% TiO₂.
Kingsland previously defined large exploration targets for both elements. The gallium target is estimated at 190–195Mt grading between 20–25ppm Ga₂O₃, equating to up to 4,875t of contained gallium. The rutile target, over the same tonnage, is estimated at 0.3–0.5% TiO₂, or up to 975,000t of contained titanium dioxide.
This test work is being conducted in parallel with a graphite-focused scoping study, which is nearing completion. Gallium and rutile are not yet included in the economic modelling for the Leliyn Project but could significantly enhance the project’s value if viable recoveries are confirmed.
Both critical minerals are experiencing rising global demand. Gallium, used in semiconductors and electronics, currently trades between US$1,000 and US$1,600/kg, while rutile commands around US$1,600/t. As geopolitical pressures mount to diversify critical mineral supply chains, Kingsland’s multi-commodity potential positions it advantageously within the market.
