Production Start...
Production at the Bootu Creek Manganese mine ceased as planned during the quarter ended 31 December 2021. The Mine was placed under care and maintenance mode since the end of January 2022.

The primary focus was to make ready, survey, and cross-rip designated areas of the Mine in preparation for aerial seeding for reforestation and this was completed in mid-November 2022. Rehabilitation of the remaining areas will continue in 2023.

Deposit Type

  • Stratabound


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.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Bootu Creek Operation was placed under Care and Maintenance following suspension of mining on 13 December 2021 and processing of ROM ore was completed on 7 January 2022. There is no current Mine Plan for the Bootu Creek Operation. During 2021, mining at the Bootu Creek Mine is carried out using a conventional open-cut method of mining, blasting and excavation using hydraulic excavators and dump trucks.
