Kingsland Minerals (ASX:KNG) said metallurgical tests found that muscovite mica is the major host of gallium with strong grades up to 135 parts-per-million of gallium at the Leliyn graphite project in the Northern Territory, according to a Wednesday Australian bourse filing.

The firm completed an exploration target for gallium at Leliyn and plans to publish a maiden gallium resource later in the year.

In light of the results, flotation test work is underway to float the muscovite mica and biotite mica to produce gallium concentrate, per the filing.
