Summary:

The Bootu Creek manganese deposits are strata-bound, located at the contact between the underlying dolomite-siltstone Attack Creek Formation and the overlying ridge forming sandstone of the Bootu Formation in the Tomkinson Group, within the Ashburton Province of the Palaeozoic Tennant Creek Inlier. The mineralised manganese bearing sandstone horizon is folded around the gentle NNW plunging Bootu Syncline, can be traced for 24 km and dips around 30o towards the fold axis.

The manganese ore is supergene enriched within a deeply weathered profile. The Bootu Creek manganese resource models have a combined strike length of 16 km, with deposit models ranging from 0.7 km to 2.9 km in length. Mineralisation widths vary from 3 m to 15 m and ore mineralogy consists predominately of Pyrolusite and Cryptomelane in a silica rich gangue within the supergene zone, overlaying a Rhodochrosite and Braunite unweathered zone at depths of greater than 90m from surface.
