1.0 INTRODUCTION

Seriti Coal (Pty) Ltd (Seriti) acquired the remaining Metsimaholo reserves as part of a purchase agreement

that involved Seriti taking ownership of several Anglo-American Thermal Coal (AATC) mines supplying

thermal coal to Eskom. Seriti plans to access the remaining reserves through the development of Metsimaholo

Colliery. Golder Associates (Golder) is currently engaged in a process to compile and submit the following:

Application to graduate the prospecting rights (FS30/5/1/1/2/10383PR and FS30/5/1/1/2/10292PR) into a

consolidated Mining Right (MR) to the Department of Mineral Resources (DMR) in terms of the Mineral

and Petroleum Resources Development Act No. 28 2002 (MPRDA); and

An Environmental Impact Assessment (EIA) in support of an application for environmental authorisation

to the Department of Environmental Affairs (DEA) in terms of the National Environmental Management

Act, No. 107 of 1998 (NEMA).

As part of the package of work, Golder was appointed to compile the preliminary closure costs for the

proposed project. The closure costs are, as far as possible, aligned to the National Environmental

Management Act, 1998: GN R.1147 (Regulations Pertaining to the Financial Provision for Prospecting,

Exploration, Mining or Production Operations). Furthermore, it is noted that the proposed amendments to the

financial provisioning regulations for mines have been published for public comment. Cognisance was taken

of these proposed amendments, to ensure that these can be incorporated into the 2019 closure costs update

ensuring a stepped approach to compliance once the new Regulations are promulgated. Indications are that

mines will have to be compliant by February 2020.

1.1 Background information

The closure costing is based on the available information as at 30 September 2018 and will require annual

updates as per GN R.1147 or as required by amended financial regulations promulgated in future. The annual

updates should also incorporate the outcomes of the specialist studies to improve the resolution of the closure

cost determination. The following information was provided for this closure cost assessment:

Locality plan indicating the locality and extent of the prospecting right and boundary within which the

shaft complex will be established (Figure 1);

Initial mine design planning by Ukwazi (Pty) Ltd (Ukwazi) indicated in Figure 2 and Figure 3 (Ukwazi

2018);

A general arrangement drawing of the proposed shaft and the related infrastructure (Figure 4; Ukwazi

2018);

Draft scoping report (Golder, 2018); and

Correspondence with Ukwazi regarding the type of infrastructure to be established on site to inform the

demolition costing components (Table 5).

2.0 MINE SITE CONTEXT

The following information is based on the Draft Scoping Report (Golder 2018) and the various planning maps

provided by Ukwazi (2018).

2.1 Locality

The project area is situated within the Metsimaholo Local Municipality, in the magisterial district of Sasolburg,

in the northern part of the Free State Province in South Africa. The nearest towns are Refengkgotso, which

straddles the northeast corner of the project area, and Deneysville which lies a further 3 km to the east as

shown in Figure 1. The area is gently undulating at 1 525 metres above mean sea level. The perennial

Taaibosspruit River meanders from south to north, through the western side of the project area. The Vaal

Dam, in part, forms the eastern edge of the project. Grazing dominates agriculture with limited areas of dry

land farming, predominantly maize. The climate is typical of the Northern Free State with warm to hot and wet

summers and cool to cold, dry winters.

Figure 1: Locality map and mining rights boundary

2.2 Legal status

Seriti Coal currently holds the prospecting mining/exploring coal rights (FS30/5/1/1/2/10383PR and

FS30/5/1/1/2/10292PR) for the Metsimaholo area which covers approximately 34 378 ha, which they propose

to graduate into a mining right. The proposed site was awarded a prospecting mining right in 2008 which was

renewed till 12 November 2018 for the primary purpose of exploring coal.

2.3 Life of mine

The Metsimaholo project pre-construction and construction phase is planned to commence in 2023. It is

expected that the construction period for the Metsimaholo project would last approximately 12 months. Mine

establishment and access development are scheduled to commence in quarter 3 of 2023. The access

October 2018 18101804-321416-1

7

development is anticipated to take an additional 12 months. The project is planned to begin its operational

phase and commence initial production in 2025, depleting in 2055.

2.4 Mining reserves

Based on preliminary studies surrounding the Metsimaholo remaining reserves, there is potential for a 30-year

life-of-mine (LoM), until 2055. The mine is envisaged to deliver an average of 2.8 to 3.0 million tonnes per

annum of coal at steady state production. The total saleable product is estimated at approximately 80 million

tons over the LoM with an average calorific value of 19 megajoules per kilogram.

2.5 Mining operations

Metsimaholo colliery is proposed to be an independent underground mine producing thermal coal from one

operational decline shaft. The Metsimaholo coal resource (top and middle seams) will be mined by

underground methods. Conventional bord and pillar mining techniques with Continuous Miners (CM) are

selected as the primary coal extraction method. Access to the orebody is planned through a box-cut

development, with a twin decline shaft system to intersect the top seam (“TMH”) floor as shown in Figure 2

and the middle seam (“MLMH”) floor as shown in Figure 3 from which the shaft bottom development and main

primary development would be initiated. MLMH will be accessed from underground via a developed decline.

Figure 2: Top seam (“TMH”) mine design map

October 2018 18101804-321416-1

8

Figure 3: Middle seam (“MLMH”) mine design map

In bord and pillar mining, parallel roads ways are developed in the mining direction. Perpendicular roads,

called splits, are developed at predetermined intervals to the parallel roads. These roads interlink, creating

pillars. The roads that are mined concurrently are determined by the size of the pillars required to support the

overburden above the coal seam and the length of the production equipment’s trailing cables. The road widths

would be designed at 7.2 m wide with an average mining height of 3 m. The pillar size is determined by the

safety factor formula that result in the pillar strength divided by the pillar load. The main access development

and production sections will be planned from the decline shaft floor consisting of either seven or nine road

development which constitutes a mining panel.

2.6 Battery limits

The planned infrastructure for the proposed Metsimaholo shaft complex is indicated in Figure 4. The itemised

infrastructure and mining components are summarised in Table 4 and constitute the battery limits for this

closure cost determination.

3.0 APPROACH AND METHODOLOGY

The approach followed to compile the preliminary closure costs can be summarised as follows:

The Metsimaholo project is a green fields project, this preliminary costing is for inclusion in the MRA

application. The cost estimate is based on preliminary mine planning information and the project

description contained in the draft scoping report;

The battery limits of the assessment were based on the conceptual layout plans and general

arrangement plans provided by Ukwazi;

The rehabilitation and closure assumptions are based on the premise that all infrastructure will be

decommissioned and demolished, all disturbed areas will be rehabilitated to achieve a post mining land

use of grazing (assumed end land use for costing purposes);

With regard to the delineation and measurement of the future planned infrastructure and mining areas,

the following approach was followed:

▪ Site orientation and naming of facilities were obtained from the associated layout maps provided; and

▪ Quantification and measurement (areas, heights, volumes and load and haul distances) were based

on infrastructure general arrangement plans and assumptions regarding the construction of each

building/component discussed with Ukwazi (Table 5);

The amount of material required to backfill the decline shaft (voids) is based on an estimate provided by

Ukwazi, as with all other aspects this will require verification and updating as the project is developed in

more detail;

The above infrastructure and areas were captured in the Golder GN R. 1147 closure cost template;

Individual unit rate tables were developed based on the latest third-party rates;

Closure measures and associated quantifications were devised, incorporating the information described;

The scheduled closure costs were computed as if the infrastructure has been constructed as planned,

and narratives provided describing key assumptions/qualifications and other considerations made with

each item;

The scheduled and unscheduled closure cost components of the costing spreadsheet have been

completed for ease of future updating;

A summary sheet providing aggregated costs for the proposed shaft complex was compiled; and

A dedicated closure cost report (this report) was compiled.

4.0 KEY ASPECTS AND ASSUMPTIONS

Key aspects and assumptions considered in the determination of closure costs are outlined below.

4.1 General

The following general assumptions have been applied:

The overall closure costs for the site could comprise a number of cost components. This report only

addresses surface rehabilitation, decommissioning of infrastructure and the final closure and control of

the site that will ensure attainment of the predetermined post mining land use with acceptable

environmental and socio-economic effects. This equates to an outside (third party) contractor(s)

establishing on-site and conducting the suite of closure related work, ranging from surface rehabilitation

to the monitoring/control and corrective action to ensure the desired rehabilitation related outcomes.

Other components of the overall costs such as staffing of the site after decommissioning, the

infrastructure and support services (e.g. power supply, etc.) for this staff as well as workforce matters

such as separation packages, re-training /re-skilling, etc. are outside the scope of this report;

Based on the above, dedicated contractors would be commissioned to conduct the surface rehabilitation,

demolition and closure related work on the site. This would inter alia require establishment costs for the

contractors and hence, the allowance for preliminary and general (P&Gs) in the closure costs;

Allowance has also been made for third party contractors and consultants to conduct post-closure care

and maintenance work as well as performance and compliance monitoring;

Potential handover of infrastructure to third parties at closure will be considered in the closure costing if

an agreement is in place with the relevant third party; should no such agreement be in place, it has been

assumed that the infrastructure will be demolished at closure;

In accordance with international accounting practices and GN R.1147, no cost off-sets due to possible

salvage of dismantled infrastructure has been considered;

Due to the board and pillar method of mining planned for the operations, surface subsidence has been

deemed to be an insignificant risk and hence measures to rehabilitate land/watercourses affected by

subsidence have not been included; and

It has been assumed that most infrastructure in underground workings will remain underground at

closure and will not be brought to surface for salvaging, therefore no costs have been allowed for the

removal of underground infrastructure.

4.2 Infrastructural aspects

The following assumptions apply to all infrastructure:

It has been assumed that concrete, decontaminated and inert demolition waste and building rubble will

be disposed of into the shaft portal. An allowance has been made for crushing and screening the

concrete demolition waste prior to backfilling;

It has been assumed that a temporary salvage yard and decontamination bay will be established during

the demolition of the infrastructure utilising the exiting dirty water management areas during

decontamination and sorting;

It has been assumed that recoverable steel will be sent to the salvage yard;

October 2018 18101804-321416-1

15

Closure costing makes provision for a nominal amount of hazardous material/waste to be disposed at

Holfontein, based on the volume of asphalt recovered during the rehabilitation of the tar access roads as

well as emanating from the PCDs and sewage plant sludge; and

It has been assumed that all internal roads and paved surfaces, including tar and gravel access roads

associated with the mine infrastructure, will be rehabilitated accordingly.

4.3 Mining aspects

The rehabilitation and closure assumptions regarding the mining areas include:

Coal will be loaded into trucks from the silos and transported off site for processing or directly to an end

user, any resulting discard or slurry management is excluded from this assessment;

It has been assumed that the shaft portal voids will be backfilled with overburden and topsoil stripped

and stored onsite during the development phase. An average load and haul distance of approximately

500 m was assumed for this purpose based on the available shaft complex drawings. This assumption

should be revised based on actual haul distance requirements once construction of the shaft complex

has been completed;

Costing has made provision for rehabilitation (sealing, plugging, etc.) of the decline shaft and the

ventilation shaft indicated in Figure 4; and

For the dirty water impoundment (pollution control dam, sewage plant dams and dirty water separation

trench), it has been assumed that the concrete will be demolished, removed decontaminated and

screened with the other concrete. A nominal allowance has been made to transport and dispose of

hazardous waste at Holfontein.

4.4 General surface rehabilitation

The following assumptions apply to general surface rehabilitation:

An allowance has been made for rehabilitation of disturbed areas, including: general levelling and

shaping all disturbed areas, ripping to alleviate compaction, scarifying the footprints and hydroseeding

with a mixture of soil ameliorants and grassland species, and

Dedicated soil sampling, fertility analysis and results interpretation will inform the soil amelioration

program.

4.5 Post-closure aspects

The post-closure aspects have been costed according to the following:

Provision has been made for surface water and groundwater monitoring for five (5) years;

Provision has been made for rehabilitation monitoring for five (5) years;

Care and maintenance of rehabilitated land has been allowed for over a period of five (5) years;

Identified potential latent and residual risks were not included in the closure costs; input data will be

refined during the EIA process for consideration during the next closure costs update; and

Allowance has been made for alien invasive plant control over areas where vegetation has been

established during and after closure, this action is included in the overall rehabilitation monitoring and

maintenance provision.

October 2018 18101804-321416-1

16

4.6 Preliminaries and general, contingencies and additional allowances

Preliminaries and general were assumed to be 6%;

Contingencies were assumed to be 10%;

Closure costing has made provision for several additional studies and integrated environmental

authorisations (Environmental Impact Assessment/basic Assessment process, Integrated Waste Water

Management Plan (IWWMP) and a Water Use Licence Application (WULA)) that will likely be required in

the event of closure.

5.0 CLOSURE COSTS, AS AT SEPTEMBER 2018

The costs are structured according to the format routinely used for the presentation of closure costs for mine

sites as per the following categories:

Infrastructural areas;

Mining areas;

General surface rehabilitation;

Post-closure aspects:

▪ Surface water monitoring;

▪ Ground water monitoring;

▪ Rehabilitation monitoring and Care and maintenance;

▪ Contingencies for post-closure aspects; and

Additional allowances:

▪ Preliminary and general;

▪ Contingencies; and

▪ Additional studies.

The summary of the scheduled closure costs as at September 2018 are included in Table 6.

The preliminary closure costs compiled within the battery limits described is based on limited information as

expected during the early stages of the project planning phase. The assessment provides a robust costing

framework for future annual updates and a basis for a step-based approach to aligning the closure planning

and costing with GN R.1147 and the anticipated update.
