Overview

StageProduction

Commodities
  • Iron Ore
Mining Method
  • Truck & Shovel / Loader
Open pit operations at Thabazimbi ceased in 2016, and the mine is currently only engaged in the rehandling of iron ore from stockpiles of ROM material from historical production.

In 2021 and 2022, mining consultancy VBKOM was contracted to complete a pre-feasibility study and estimate the remaining in-situ mineral resources for Vanderbijl deposit, which are reported in this report. Further studies to define mineral reserves and life of mine are planned to commence in 2023.

Deposit Type

  • Banded iron formation


Summary:

Thabazimbi mine is located in the Limpopo province close to the town of Thabazimbi.

The iron ore at the Thabazimbi Mine consists of high-grade haematite (Fe2O3) which occurs in the basal parts of the Penge Formation and is underlain by the chert-poor dolomite of the Frisco Formation.

The Penge formation is usually in conformable contact with the underlying Malmani Subgroup and is composed mainly of gruneritic-banded chert with interbedded carbonaceous shale. However, at the Thabazimbi Mine the chert-rich basal part of the Penge Formation is missing. The basal unit of the Penge Formation therefore unconformably overlies the Malmani Subgroup and is most likely due to normal faulting in the Thabazimbi area.

Ore genesis is of a chemical nature, where secondary Haematite replaced chert within the BIF. Later stages of ferruginisation followed to produce high-grade laminated to brecciated iron ore. The occurrence of iron ore is structurally controlled, with faults serving firstly as conduits for iron-rich fluids and later as mechanisms for displacing (and/or duplicating) ore zones.

Local collapse structures within the underlying dolomites produced brecciated zones within the BIF, which were then filled by iron-rich fluids. A regional network of diabase sills and dykes served as trapping mechanisms for mineralising fluids in the lower section of the BIF, which resulted in an enriched lower section and a less-enriched upper section of the P ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

Thabazimbi mine in its later years extracted iron ore via conventional opencast mining methods of drilling and blasting followed by loading and hauling via a truck and shovel fleet. Mining in 2015 was conducted in three pits that are geographically separated from one another.

Open-pit mining was stopped on 30 September 2015 and only existing stockpiled RoM material will be fed to the beneficiation plant.

In 2021 a pre-feasibility study on restarting mining operations in Thabazimbi was approved and a feasibility study prepared.

Options being explored are for a 3 million tonne-per-annum opencast run-of-mine (Mtpa ROM) or a 5Mtpa ROM operation. Should it be decided to restart operations, we believe that mining operations could commence in 2026. A 5Mtpa ROM mine would be able to supply more than 80% of our iron ore requirement over a 20-year life of mine, sustaining some 400 jobs.
