Project Description

The project entails an IFC revolving loan to Finsch Diamond Mine in South Africa (Finsch), which is 74% owned by Petra Diamonds Limited (Petra). The financing, that will be provided jointly by IFC and a South African Bank (Rand Merchant Bank), will enable Petra to: finance the Finsch mine expansion program; strengthen Petra’s overall liquidity position following its move to the London Stock Exchange (LSE) main-board; and, fund other general corporate requirements (through repayment of intercompany loans) (collectively, the Project). Petra was publicly listed on the Alternative Investment Market (AIM), which is the LSE’s international market for smaller growing companies, but moved to the LSE main-board in December 2011.

Finsch was acquired by Petra from De Beers Consolidated Mines Limited (De Beers) in September 2011 after which Petra assumed full management of the mine. The acquisition of Finsch increases Petra’s mines to eight (Cullinan, Koffiefontein, Kimberley Underground, Finsch, Sedibeng, Star and Helam in South Africa, and Williamson in Tanzania). Petra is an existing IFC client and IFC was involved in financing Petra’s Williamson Diamond Limited expansion programme in Tanzania and exploration concessions in Botswana.

Petra will implement a development plan at Finsch to increase production from 1.5 million carats (Mcts) per annum to 2 Mcts per annum by 2018, by gradually opening up Block 5 below the current Block 4 operations, supported by a surface tailings treatment program. Production levels from underground will be maintained during the transition from Block 4 to Block 5 by developing smaller sub-level caves within the Precursor ore body (adjacent to the main ore body) at Block 4 and within Block 5 itself. Petra foresees a long life for the operation and has a current mine plan of 18 years, though the ore body remains open-ended at depth.

Finsch’s expansion programme entails deeper underground development within the same surface footprint and with no increase to this footprint. One of the challenges related to this expansion programme is securing sufficient water resources to supply the proposed expansion without impacting negatively on the needs of the local (predominantly farming) communities. Any impacts that may arise as part of the mine expansion project will be addressed through the EMPR amendment exercise that the mine commissioned in July 2011.

Finsch is situated in the Kgatelopele Local Municipality within Siyanda District Municipality in Northern Cape Province of South Africa. The mine is located approximately 165 km northwest of Kimberley, with Lime Acres approximately 3.5 km to the northeast, Danielskuil 30 km to the north-northeast and Papkuil 31 km to the southeast. The majority of Finsch workforce lives in Lime Acres and Danielskuil; Lime Acres was built and is run for the employees of Finsch and Pretoria Portland Cement (PPC) which is situated adjacent to the mine. Danielskuil also houses employees from PPC. According to the 2001 census, Lime Acres had a population of nearly 7 000 and Danielskuil had nearly 9 000 against a total of almost 21 000 for Siyanda District Municipality.

The Northern Cape has the smallest economy of the nine provinces in South Africa for which Siyanda District Municipality accounts for about 30%. The major economic activities and sources of employment in this frontier region of South Africa are mining and agriculture; tourism is the fastest growing sector. Unemployment is high and economic opportunities limited.

The mine is surrounded by several farms and the PPC Lime operations. There are no perennial surface water systems located or traversing the mine property and the pre-mining land capability is classified as extensive grazing land. Soil depth limits most of the area’s agricultural potential and when combined with the erratic and unpredictable rainfall, the land is considered most suited to conservation/wilderness land. Thus with the acquisition of Finsch and surrounding properties in 1962, De Beers initiated a wildlife conservation policy, which resulted in sections of properties being enclosed by a game fence and the areas being managed as game farms.

Diamonds were first discovered at Finsch in 1930. Mining commenced in 1964, when a treatment and recovery plant was erected at the pipe. Initial operations were by means of open pit mining to a depth of 430m in 1992, where-after an open stoping underground method was used to a depth of 530m. The current method is by means of block-caving technology. The mine has one main shaft in which two 28-ton skips are used solely for ore hoisting, while two personnel elevators also operate in this shaft. The treatment process used at Finsch consists of three basic stages: ore preparation by crushing, washing and screening; concentration of the sized material and preparation by means of Dense Media Separation; and sorting. Old residue deposits are also reprocessed to recover residual diamonds. Diamonds extracted from Finsch are generally 60% of industrial quality and 40% of gem quality.

Finsch’s current surface operational areas consist of a processing plant area, headgear infrastructure, workshops, administration infrastructure, waste rock dumps, two coarse residue deposit facilities (CRDs) and three fine residue deposit facilities (FRDs). There are four residential areas in the town, a clinic, shops and schools. This infrastructure is linked with Eskom power lines, tar and gravel roads, a local airstrip, and the Kimberley/Sishen railway line which passes about 1.5 km to north of the mine.

Overview of IFC's Scope of Review

The review of this Project consisted of appraising technical, environmental, health, safety and social information submitted by the company, and assessing the company’s operations by a field visit conducted by the project team. Key focus was a review of management systems and organization, including review of Finsch Diamond Mine’s approved Environmental Management Programme Reports (EMPRs) - the South African equivalent of an Environmental Impact Assessment (EIA) for mining projects, and their associated Performance Assessments Reports; approved Social and Labour Plan (SLP); Rehabilitation and Closure Plans; and key monitoring data. The team visited the mine on the 10th of November 2011, and met key mine representatives. Field visits were organized to different parts of the mining areas as well as to ancillary infrastructure. Various discussions were also held with key representatives from Petra Diamonds Limited.
