Kolomela is a predominantly direct shipping ore (DSO) operation with a crushing and screening plant treating high-grade (Fe = 61%) run-of-mine, and a small-scale UHDMS facility treating medium-grade (50% = Fe < 61%) run-of-mine.

Deposit Type

  • Banded iron formation

Summary:

The Kolomela ore deposit is located on the southern ends, of the iron ore belt in the Northern Cape, South Africa.

The Kolomela mine orebodies comprise hard, high-grade, conglomeratic and laminated haematite orebodies. The ores have been preserved as three separate orebodies within basinal and graben structures up to 2km long, 400m wide and 300m deep.

The only BIF present at Welgevonden appears to be that of the Kuruman Iron Formation, with the Griquatown Iron Formation having been removed by erosion. The main structural characteristic in the west of the Welgevonden area is the Wolhaarkop Dome, an overturned anticline replicating the larger Maremane Dome, which occurs in the east of the deposit.The ore bodies are intensely folded and faulted, and are preserved within erosional remnants that are not as continuous, but are of similar structural types to those encountered at Sishen.

Two tectono-stratigraphic settings for the ore bodies have been defined by Alchin and Botha: a palaeosinkhole-hosted setting applicable to the Ploegfontein, Leeuwfontein and Klipbankfontein ore bodies; and a synclinal basin setting applicable to the Welgevonden and Kapstevel ore bodies. Marginal deformational effects, thought to be related to the ~2.2 Ga Kheis event, occur towards the west of the deposit and decrease rapidly to the east. The scattered nature of the ore bodies at Welgevonden could be due to the removal of upper lithologies by erosion and/or due to smal ........

Mining Methods

  • Truck & Shovel / Loader

Summary:

The Kolomela Mine is conventional drill and blast and truck and shovel open-pit operations with ex pit ore at Kolomela hauled to designated finger stockpiles from which a run-of-mine blend is delivered. The Kolomela finger stockpiling is necessary to produce the correct run-of-mine blend for the predominantly DSO operation.

Currently, the Leeuwfontein, Klipbankfontein and Kapstevel North ore bodies are mined. The 2021 LoM plan also includes mining of the Kapstevel South ore body. The 2022 LoAP also planned mining of the Kapstevel South ore body, with waste stripping that commenced in 2020. The first ore from our Kapstevel South pit is expected to be delivered in the first half of 2024.

The Ploegfontein deposit located within the Kolomela mining right area is earmarked as the next deposit to be considered for conversion to Ore Reserves to restore the annual production output of Kolomela mine from 2027 onwards when the high-grade Leeuwfontein, Klipbankfontein and Kapstevel North pits' Ore Reserves have been depleted.

The Sishen Iron Ore Company (Pty) Ltd is proposing to incorporate the Heuningkranz Section into the existing Kolomela Mine mining right. Mining at the Heuningkranz Section will be from two (2) open pits, the Heuningkranz North and Heuningkranz South Pits. The construction of infrastructure and the stripping of overburden is scheduled to commence at Heuningkranz in 2031, with the first ore being mined and processed in 2034. Activitie ........
