Grootegeluk Mine

Grootegeluk Mine is situated in the Magisterial District of Lephalale in the Limpopo Province of South Africa, some 240km northwest of Pretoria (Tshwane) and 70km south of the border with Botswana. Located at latitude 23°39’S and longitude 27°43’E, the site is accessed via a tarred road, the R517, between Modimolle (formerly Nylstroom) and Lephalale (formerly Ellisras).

Exploration history in the Waterberg Coalfield dates from 1920, although larger scale exploration did not commence until the 1940’s. Following intensive exploration by Iscor, beginning in 1973, a mining lease was granted in 1979. In 1980 Grootegeluk Mine was established as the first and to date the only coal mine in the Waterberg Coalfield. Total mine production (including discard) since 1980 is some 561Mt rendering some 282Mt of saleable coal (refer to Table 2.17). Grootegeluk Mine is a conventional open-pit operation. Processing is through five coal preparation plants with a combined operating capacity of 2,979ktpm. A sixth coal plant is under construction. Saleable products include semi-soft coking coal, metallurgical coal and thermal coal, with the latter predominating as a dedicated supply to the Matimba Power Station. Metallurgical coal is primarily supplied to Mittal steel mills, with certain semi-soft coking coal exported via ports at Durban and Richards Bay in the KwaZulu-Natal Province of South Africa.

New Clydesdale Colliery is primarily an export colliery which currently produces coal for both the export and domestic markets. It mines the Nos. 1, 2, 4 and 5 Seams in the Vaalkrans North opencast operation and No. 2 Seam from the pillars in the Vaalkrans South underground Area.

New Clydedale Colliery produces A-grade coal for sale on both the export and domestic markets. It exports, through the Richards Bay Coal Terminal, steam coal with a high calorific value, high volatiles and medium sulphur. Some A-grade product is sold on the domestic market. Future underground mining will take place in the Diepspruit Nos. 1 and 2 Seams.

Details on New Clydesdale Colliery’s infrastructure appear in Table 2.33 and details of New Clydesdale Colliery’s historical operating statistics appear in Table 2.34.

Discard facility Discard card Medium life asset.

The plant feed during 2003/2004 is double that of 2005 as a consequence of coal buy-ins from third parties and the stooping of underground pillars. New Clydesdale Colliery is geared to serve the current Richards Bay Coal Terminal (“RBCT”) entitlement (common user entitlement) and supplies approximately 180kt of A grade product to the inland market. The budget is compiled to serve these markets. To meet these budget requirements, the product is a function of the plant feed and yield. Therefore, the higher the quality of raw coal supplied, the higher the yield in the plant. New Clydesdale Colliery currently has various production sources resulting in yields ranging from approximately 55% to 72%. This will determine the rate of plant feed required.

North Block Complex

The North Block Complex comprises the following:

  • Glisa Colliery;
  • Strathrae Colliery;
  • Eerstelingsfontein Project; and
  • Belfast Project.

The operations in the North Block Complex are situated in Mpumalanga Province between the towns of Carolina, Arnot and Machadodorp. Since 2001 North Block Complex has produced some 8.6Mt of coal. Historical production information appears in Table 2.35.

Glisa Colliery is situated approximately 280km east of Johannesburg, near the town of Belfast, in the Province of Mpumalanga. The colliery produces a D-grade product which is mainly supplied to the domestic market. Glisa Colliery consists of opencast operations, which produce thermal coal for Eskom, and underground operations, which produce D-grade coal. The underground at Glisa Colliery will be depleted by March 2006 and the opencast at Glisa will be depleted by June 2006.

Strathrae Colliery is located approximately 200km northeast of Johannesburg and approximately 15km south of Wonderfontein on the Carolina – Wonderfontein road, in the Province of Mpumalanga. It is a relatively new acquisition by Eyesizwe that was refurbished and commissioned in October 2004. The colliery produces thermal coal for Eskom and metallurgical B-grade coal. Strathrae Colliery is an opencast operation, with a four-year LoM. Strathrae Colliery expects to reclaim 355kt of material from a dump, which will be sold to Eskom, over a 12-month period.

The Eerstelingsfontein Project area is located approximately 230km north-northeast of Johannesburg and 20km south from the town of Belfast. Eerstelingsfontein will be mined by means of an opencast operation using the strip mining method and RoM coal will be transported by road to the Strathrae plant.

The Belfast Project reserve area is located approximately 220km north-northeast of Johannesburg near the town of Belfast. A feasibility study has been conducted on this project.

Twistdraai Colliery

The Twistdraai Colliery is located in the centre of the Highveld Coal field, some 11km east of Secunda in the Mpumalanga Province. The region is typified by low rolling hills typical of the Karoo Sequence of the Highveld region. The Colliery is situated predominantly on the farms Goodehoop 290IS, Grootvlei 293IS, and Frischgewaagd 294IS in close proximity to the Sasol Synfuels factory in Secunda. The export mine at Twistdraai was commissioned in 1996. A total of 27.88Mt of coal has been exported, beneficiated from 76.05Mt at the Twistdraai Export Plant from 1996 through to 30 June 2005. During January 2006 Sasol signed a Memorandum of Understanding with Eyesizwe to acquire a 35% stake in Twistdraai Colliery.

2.6.9

Sintel Char Project

Kumba Coal was given board approval to commence with construction of a Sintel Char Plant in the vicinity of the Grootegeluk coal mine. Construction is set to commence in 2006 with commissioning planned for the latter half of 2007. The objective of the Sintel Char Plant is to convert metallurgical suitable coal to a high carbon product by taking out all unwanted volatiles and tars and carbonising the product to a desired hardness and reactivity. The sintel char to be produced is used in the South African ferrochrome industry, which uses a blend of coal as a reductant in the smelting process.

The Sintel Char Project is expected to commence production in 2007 and ramp up to full production by 2009, processing some 210ktpa to produce some 138ktpa of Lumpy Char and some 11ktpa of Char (<20mm). Estimated real capital expenditures for the project are expected to be some ZAR182m.

2.6.10

Inyanda Project

The Inyanda Project is located on the farm Kalbasfontein 284JS, Witbank district, 14kms north of Witbank. Kumba Coal owns the surface rights to Portion 21 of the farm Kalbasfontein 284 JS. An application for a “new order” Mining Right for the Remaining Extent of Portion 20, Portion 21 and Portion 22 of the farm Kalbasfontein 284 JS was submitted to the DME on 27 October 2004. The Inyanda Project is an equal joint venture between Eyesizwe and Kumba Coal. The project has been approved by both the Kumba Coal and Eyesizwe Boards.

The Inyanda Project is expected to commence production in 2007 and ramp up to full production by 2008, processing some 1.4Mtpa to produce an average of 1Mtpa of A-grade export steam coal. Estimated real capital expenditures for the project are expected to be some ZAR257m.

2.6.11  

Mafube JV Phase II Project

Mafube Colliery is a 50 : 50 joint venture between Anglo Coal and Eyesizwe. Mafube Colliery is located approximately 180km east of Johannesburg, between the towns of Middleburg and Belfast, in the Province on Mpumalanga.

The No. 1 and No. 2 Seams at the colliery will be exploited in two phases:

  • Mafube JV Phase I is currently expected to supply approximately 1,180ktpa of coal to Eskom’s Arnot power station until 2007.
  • The Mafube JV Phase II Project will be a large opencast mine supplying an average of 6Mtpa RoM to a coal processing plant to produce an average of 2.7Mtpa of “A” grade export quality thermal coal and supply an average 2.1Mtpa of middlings coal to Eskom’s Arnot power station. The project is expected to commence production in 2007 and ramp up to full production by 2008. Anglo coal commenced with the Phase II Project feasibility study in August 2004.

According to the agreement Exxaro will only participate in the Mafube JV Phase II Project and the FM and associated NPVs in Section 14 reflect Phase II only. Estimated real capital expenditures for the project are expected to be some ZAR2,000m. Two scenarios are presented in the CPR, Scenario I excludes Nooitgedacht Inferred Resources and Scenario II includes Nooitgedacht Inferred Resources.

2.6.12  

Belfast Project

The Belfast Project is located approximately 7km to the south of the town of Belfast. The project area is linked to the N4 national road and the main railway line to Maputo. It is also connected via Carolina with the Richards Bay line. The project will mine export and thermal coal using opencast and underground mining methods.

The Belfast Project is expected to commence production in 2008 and ramp up to full production by 2010, processing some 2Mtpa to produce an average of 1.2Mtpa of washed coal and 0.7Mtpa of coal for supply to Eskom. Estimated real capital expenditures for the project are expected to be some ZAR188m.

2.6.13  

Ingcambu Project

The Ingcambu Project is situated 5km north east of Ermelo in the Province on Mpumalanga. Ingcambu is a joint venture between Ingcambu Investment (Proprietary) Limited (40%); Eyesizwe (50%) and Anglo Khula Mining Fund (10%). The project mines export and thermal coal using opencast and underground mining methods.

The Ingcambu Project has commenced production in 2005 and is expected to process some 0.7Mtpa to produce some 0.25Mtpa of Eskom middlings and 0.25Mt of export steam coal in 2006. The level of confidence in the data is limited and therefore SRK have restricted the LoM to 2006 (the LoM is limited to access to portion 26 of the farm Uitgevallen – for further details refer to Section 3.3.5).

2.6.14  

Exploration Potential

Kumba Coal and Eyesizwe have eight coal exploration projects in various development stages as indicated in Table 2.38 below.

Table 2.38 Coal Exploration Properties: Development Stages
Exploration Project  Development Stage
Grootegeluk West 
(five farms)
This project is the natural expansion for Grootegeluk, and has inferred resources. It is deemed an Exploration Area.
Van Wykspan/Zonderwater This project is for the underground extraction of export quality coal in the Waterberg Coalfield, the resources have been explored to an Inferred status and is deemed to be an Exploration Area.
Vredehof This exploration area in northern KwaZulu-Natal has no classified mineral resources and is deemed an Exploration Area.
Strehla This project is situated in the Witbank Coalfield some 30kms to the east of Delmas, The coal has been drilled to a Indicated Resource status, but no feasibility work has been done and is therefore deemed to be an Advanced Exploration Area.
Moranbah South This project in the Bowen Basin Qld. has significant inferred resources and has been the subject of a pre-feasibility study. It still requires some exploration and is therefore an Advanced Exploration Area.
Waterberg (South and North)   This area has been extensively drilled and undergone a pre-feasibility study, Although the resources are classified at Measured and Indicated levels, the marketing of the coal is problematic. This project is deemed an Advanced Exploration Area.
Sheepmoor (North) This project in eastern Mpumlanga, has been explored to a Measured and Indicated status, some trial mining has occurred and feasibility studies undertaken. Some mining technical problems require alleviation before development can take place. This project is deemed an Advanced Exploration Area.
Carolina There has been extensive drilling and geological modelling in this area, and the resources can be classified as Indicated. No pre-feasibility studies have been commissioned and as such the area is deemed to be an Exploration Area.
