SnapshotThe expansion of the Mt Marion processing plant was completed in June 2023.

MinRes announced encouraging exploration results at Mt Marion which confirm significant opportunity for open pit extensions and underground potential.

The cooperation agreement to convert Mt Marion spodumene concentrate into lithium battery chemicals with Ganfeng Lithium Co. Ltd (Ganfeng) was mutually terminated.

Summary:

The Mt Marion lithium mineralisation is hosted within a number of sub-parallel, northeast to northwest trending pegmatite intrusive bodies which dip at between 10° and 30° to the west. Individual pegmatites vary in strike length from approximately 300 m to 1,500 m and average 15 m to 20 m in thickness, but vary locally from less than 2 m to up to 35 m thick. The pegmatites intrude the mafic volcanic host rocks of the surrounding greenstone belt.

To the southwest of Area 2W, large intervals of spodumene-bearing pegmatite intersected during the 2016 drilling are interpreted to be part of a sub-vertical, northeast striking feeder zone. The feeder zone is interpreted to be around 40 m to 80 m wide, extending approximately 400 m along strike and down to over 500 m below surface, and is open at depth.

The lithium occurs as 5 cm to 30 cm long greywhite spodumene crystals within medium grained pegmatites comprising primarily of quartz, feldspar, spodumene and muscovite. The spodumene crystals are broadly oriented orthogonal to the pegmatite contacts. Some zoning of the pegmatites parallel to the contacts is observed, with higher concentrations of spodumene occurring close to the upper contact.

Lithium mineralisation occurs as spodumene crystals which are hosted within quartz-feldspar-muscovite pegmatites.

The spodumene-bearing pegmatites were interpreted and wireframed in section based largely on the geological logging of pegmatite intersections, along with geochemistry (e.g. Li2O, Fe and MgO content).
