The Thakadu Copper Project is hosted within the Matsitama Metasedimentary Group, comprising carbonaceous and argillaceous metasediments which are enclosed within foliated granitoids of the Mosetse Complex. The Matsitama Metasedimentary Group lies in structural contact or unconformably over the granite/gneisses and forms two main areas of outcrop; the Matsitama Belt (which hosts the Thakadu and Makala deposits) and the arcuate “Bushman Belt” to the north where the Thakadu Mine is situated. The Matsitama Metasedimentary Group consists of greenschist to amphibolite facies metamorphic rocks with the following types of rocks identified: calcareous sandstones, conglomerates, pelites, arkoses, quartzites, volcanic tuffs and agglomerates, amphibolites, limestones, banded ironstones and serpentinites.

The copper mineralisation is broadly strata-bound and hosted by a complexly folded sequence of felsic sedimentary rocks, about 50 150m thick. The felsic metasedimentary sequence includes siliceous carbonates, biotite schists, calcareous pelites and graphitic carbonates. The stratigraphy above and below the felsic package is dominated by amphibolite derived from mafic/intermediate intrusives, volcanic and volcaniclastic rocks.

Hypogene sulphide mineralisation is predominantly hosted by quartz and quartz-carbonate rich arenites and to a lesser extent in biotite schists. Chalcopyrite is the dominant Cu-sulphide with minor bornite. Pyrrhotite is present in some zones and the sulphides generally occur as irregular stringers and disseminations in the quartz-carbonate rich units and in irregular quartz-carbonate veined zones.

Pyrite is common throughout the sequence and galena and sphalerite mineralisation is poorly and sporadically developed. Hypogene mineralisation is capped by secondary oxide and minor supergene copper mineralisation at depths of approximately 45m to 55m below surface.

The Thakadu mineralisation has been traced from surface to approximately 420m below surface and over a strike length of some 600m. The deposit dips at approximately 44° on 224° (dip and dip direction) with increased deformation and steepening dips up to 70° locally in the east of the deposit.

The copper mineralisation is generally hosted by two quartz carbonate units near the base of the felsic metasedimentary package and the footwall amphibolite unit is distinct from the hangingwall amphibolite unit. Copper mineralisation also occurs in other quartz-carbonate beds, but is not as laterally extensive. Where mineralisation is well developed, it often spreads into the surrounding (predominantly biotite) schist units.

The Thakadu Copper Project hosts various different styles of mineralisation, but is dominated by hypogene sulphides (chalcopyrite ± bornite) hosted within the quartz-carbonate units with lesser near surface oxide zone. There has been some secondary supergene alteration and enrichment but it is sporadic and poorly developed.

The copper mineralisation is preferentially developed within two of the quartz carbonate units towards the base of the felsic sequence and locally quartz-carbonate rich veins. It often transgresses from the quartz-carbonate unit into adjacent biotite schists or graphitic conglomerates where well developed. The mineralised zone varies in thickness from about 35m at the eastern near surface end of the Thakadu Copper Project, to less than a metre thick further to the west and as it pinches down toward the base.

Thakadu's ore is transported by road to the Mowana mine processing facility and it shares the Mowana mine infrastructure and management.
