The Kintyre uranium deposit is an unconformity-associated, vein type orebody (similar to those of the East Aligator River Province, NT, Australia and the Athabasca Basin, Saskatchewan, Canada) within the Proterozoic Paterson Province of Western Australia, 60 km south of the Telfer gold mine and 260 km NNE of the town of Newman.

The deposit lies within the Rudall Complex which comprises two suites, older, possibly Archaean, granite gneisses with inliers of quartzo-feldspathic gneisses, schists, iron formations and mafic/ultramafic gneisses, and a younger suite dominated by quartzite, quartz-muscovite schist and lesser BIF, metachert, graphitic schist, marble, chlorite-carbonate schists and metabasalt.   The latest deformation in the complex is dated at between 1530 and 1330 Ma.

The Rudall Complex is overlain above a marked angular unconformity by the Coolbro Sandstone of the Yeeneena Group which comprises quartz sandstone with rare thin carbonaceous mudstone and shale interbeds and conglomerate bands.   This Group was deformed at around 1130 Ma.

The Kintyre ore zone occurs within chlorite-quartz schists, chlorite-carbonate-quartz schists and variably chloritic and garnetiferous quartzite (metachert) associated with carbonates in the axial zone of a recumbent, gently ENE plunging antiform.   The dominant style of mineralisation comprises F1 cleavage controlled pitchblende veining which forms discrete ore zones within the upper limb of the F1 antiform.   Chlorite, dolomite, ankerite and calcite are dominant vein gangue, with either or both carbonate and chlorite predominating.   Weaker disseminated pitchblende is also recognised.   Accessory and trace bismuth, bismuthinite, chalcopyrite, bornite, galena and gold are associated with the pitchblende.

The main orebody has a strike length of 400 m, is 100 to 200 m wide and up to 70 m thick.   This volume is made up of narrow pitchblende veins in sets within 1 to 10 m thickness ore zones, separated by barren host schists.   These ore zones in aggregate make up the ore lense that dips north at 20 to 50°.   Alteration is mainly chloritisation and weak localised hematisation.

The deposit has a total resource of - 36 000 t of U3O8 with grades averaging from 1.5 to 4.0 kg/t U3O8, comprising:
    Probable reserve - 22 000 t,
    Indicated resource - 11 000 t,
    Inferred resource - 3 000 t,
These figures were based on a 0.5 kg/t U
3O8 cut-off and include the blind Whale and Pioneer deposits within 1500 m of the main Kintyre ore lens.
