3000 KCM jobs on the line as the mine suspends operations at the Nchanga underground unit

KONKOLA Copper Mine Plc has written to its workers at Nchanga, informing them that the Chingola-based underground mine will be put on care and maintenance with immediate effect.

According to a letter addressed to the employees, KCM stated as follows: “This information must be communicated to all staff by Friday 31st July 2015. This includes: all KCM employees and contractors. KCM Plc has been informed by Copperbelt Energy Corporation (CEC) that electricity power supply will be reduced by up to 30 per cent. As a result of the power reduction, KCM has decided as follows: To place Nchanga underground operations on care and maintenance, scale down on the Nkana refinery operations. The above measures are with immediate effect until further notice,” read the notice letter in part.

And Kitwe-based Anglican priest Fr Richard Luonde said his friends who work at Nchanga mine had called him to complain about KCM’s decision.

“I have this letter here, someone just called me and said, ‘Ba Father Luonde, please help us advise this government. Very shortly, there will be mayhem in Nchanga. Bytomorrow morning, it will be disaster’,” Fr Luonde said.

“What this means is that when they put this on maintenance, there are close to 3,000 workers at Nchanga underground who will be declared redundant. People will lose jobs and their families will suffer.”

He said it was clear that KCM was using power cuts as reason to shut down its operations at Nchanga when it has always been wanting to reduce its workforce.

“This KCM has always been wanting to reduce its labour force and they are now using the Zesco load-shedding to get rid of workers. But when they get rid of these 3,000 employees, they will be getting rid of over 20,000 people because these workers have families,” said Fr Luonde.

And sources within senior KCM management revealed that Vedanta Resources, the owners of the mine, had refused to invest in the Nchanga underground mine and management had no option but to close.

“We are folding, yes… we saw this coming because the owners of KCM, Anil Argawal and his friends, have refused to invest in underground operations at Nchanga. We told them at several internal meeting that this is a terrible mistake but they are not ready to do that,’’ sources said.

“The technical aspect of this issue is that Nchanga underground is an old mine as you know; it’s very deep now, and in mining, the deeper you go, the more costly mining becomes. But this is a manageable situation by the investor because we still have a rich copper ore body underground. This issue of saying it’s because of power cuts is just an excuse they want to put up.”

The sources said news of the mine shutting down operations had created serious apprehension among workers and the labour movement.

“As we speak, the president of the Zambia Congress of Trade Unions Nkole Chishimba is on his way to KCM. Other union officials are here and they have told us in our faces that they will not accept this; they have challenged KCM and the government, which has a stake in KCM, to invest in the mine and maintain these jobs,” the source said.

Mineworkers Union of Zambia general secretary Joseph Chewe said the union would issue a statement after receiving official communication.

“We have received those reports but we are waiting for official communication. We are making frantic efforts to get the details as we speak. We will give you details later together with our position on this matter,” said Chewe.

And National Union of Miners and Allied Workers general secretary Steven Mukupa said the union had also gotten the report and it would be unfortunate if KCM decided to take a drastic measure without involving stakeholders.

“I am just waiting for an email over this but we have heard the reports. What we want is official communication. They (KCM) should have alerted us, this is a serious matter. It is extremely unfortunate if that’s what they have done. We will give you our comprehensive statement later,” said Mukupa.

Ndola Lime in $16.5m ZCCM-IH capital fund

TRYNESS MBALE, Lusaka
ZCCM-INVESTMENTS Holdings (ZCCM-IH) has provided a US$16.5 million loan for the recapitalisation of Ndola Lime Company (NLC) project to increase lime production.
The project, known as VK-2, is expected to be commissioned in September and is anticipated to increase lime production by 500 tonnes per day to 900 tonnes and also substitute the less efficient rotary kiln’s capacity of 400 tonnes per day.

This is contained in the firm’s directors’ interim summary report for the six months period ended March 31, 2015 availed to the Daily Mail on Thursday.
“The recapitalisation project at NLC continued. ZCCM-IH provided additional shareholder loan of US$16.5 million for the NLC recapitalisation project,” the report reads.

The VK-2 will use coal as opposed to heavy fuel oil (HFO).

This will enhance the prospects of reducing operating costs and make the products competitive.

Meanwhile, ZCCM-IH has reversed the decision to use Mawe Exploration and Technical Services Limited, to play a catalytic role in exploration of base metals and other minerals, oil and gas following a review of the structure and operations of the firm.

In 2013, ZCCM-IH incorporated its wholly owned subsidiary, Mawe Exploration and Technical Services Limited whose objective was to develop local content and beneficiation capabilities, small-scale mining development, as well as the provision of attendant quality mining services.

“Following a review of the structure and operations of Mawe Exploration and Technical Services Limited, ZCCM-IH reversed this decision and will now retain the functions that were to be performed by it into a technical directorate within the holdings. This decision is aimed at rationalising costs related to the named activities,” the report reads.

SEC happy with government stance on ZCCM-IH

CYNTHIA MWALE, Lusaka
THE Securities and Exchange Commission (SEC) has hailed Government for fulfilling its commitment to start the process of scaling down its shareholding in ZCCM-Investment Holdings (ZCCM-IH) which currently stands at 87 percent.

One of the Lusaka Stock Exchange (LuSE), listing requirements stipulates that an issuer (listed company) must have a minimum of 25 percent of each class of equity securities held by the public. Therefore no single shareholder should control more than 75 percent of the equity in any company .

SEC director for market supervision and development Mutumboi Mundia said compliance to the minimum free float levels of 25 percent is an important one which must be enforced fully to have more shares available for trading on the local bourse.

“As regulator of capital markets, we are delighted that government has commenced the process of reducing its shareholding in ZCCM-IH,” Ms Mudia said.

Last week, ZCCM-IH announced that Government has sold 15.8 million shares in the holding company worth K579 million to NAPSA.

“Increasing the number of shares available for trading is one of the things we need to address to improve liquidity [that is, the ease to buy and sell shares] on the stock market.

“We need more companies to list and offer shares the stock market and as you may be aware SEC is currently, spearheading a capital markets awareness campaign aimed at sensitising Zambians about saving and investment opportunities in the capital markets,” she said.

Ms Mundia said the regulator of the capital market is encouraging ordinary Zambians to empower themselves and secure their futures through buying shares, unit trusts, bonds and other capital market products.

“It is, therefore, in our interest to ensure these products are made available on the market. Government’s step to sell down its holding in ZCCM-IH is plausible for many reason, including that of demonstrating good governance by upholding regulatory compliance and also creating the much needed investment opportunities ,”she said.

Ms Mundia said the development to sell more ZCCM-IH shares to ordinary members of the public through the LuSE is commendable.

She urged Zambians to visit LuSE or SEC licensed stock broker for advice on the development noting that the commission’s mandate is protecting investors in the capital markets will remain a priority and it is determined to see a better savings and investment culture emerge among Zambians.

Nava Bharat’s Zambia project to achieve financial closure by June-end

Hyderabad-based Nava Bharat Ventures Limited is likely to achieve financial closure by this month end for a 300-Mw coal-fired thermal power project being set up in the African nation, Zambia.

The power project is an extension of the coal mine operations of Mamba Collieries Limited (MCL), in which the company’s wholly-owned subsidiary Nava Bharat (Singapore) Pte Limited holds 65 per cent stake. The balance is held by ZCCM-Investment Holdings Plc, an investment arm of the government of Republic of Zambia.

The company has already signed a power purchase agreement (PPA) for a 20-year period with the government of Zambia and the government’s decision to extend the guarantee against the utility’s payment obligation as insisted by the project lenders has finally cleared the way for the financial closure, according to GRK Prasad, executive director of Nava Bharat Ventures.

Nava Bharat has so far invested about $ 223 million in the project mostly as its equity out of a total funding requirement of $830 million for the coal and power projects. The company had revived the coal mining operations in MCL, which is estimated to have 140 million tonnes of high grade coal and thermal coal reserves spread on 1070 hectares out of a total concession area of 7,900 hectares.

Responding to a question in a recent earnings conference call in this regard, Prasad said the coal mine operations had achieved break even in 2014-15 with a total volume of 100,000 tonnes of high-grade coal earning about $ 48 a tonne.

“Our Zambian company — Mamba Collieries Limited has achieved considerable progress with reference to debt financing. After the latest stipulation of lenders on the enhancement of security mechanism, the Zambian company has been able to obtain the approval of the Government of Zambia for a callable guarantee against the utility’s payment obligation for power purchase,” Prasad said.

KCM importing toxic copper concentrates

KONKOLA Copper Mines has started importing copper concentrate from Chile which contains arsenic, a toxic chemical element that causes cancer if exposed to humans in uncontrolled quantities.

But the mining company says it has taken the necessary precautions to ensure that “this and all impurities are captured and safely stored so that there is no adverse impact on the environment or human health.”

According to studies, concentrated arsenic content can contaminate groundwater, leading to widespread epidemics and if exposed in larger quantities to humans, the brittle steel-grey semi-metal can cause arsenic cancer.

Technical sources at KCM also feared that the copper concentrate the company was importing from South America could be harmful to humans and the environment.

The sources said the workers who are handling the copper concentrate feared for their health as the consignment from Chile had levels of arsenic as high as four per cent.

“If you recall from your chemistry, arsenic is not like any other ordinary chemical friendly to the environment and human beings. Arsine gas is highly toxic. The toxicity is due to arsenic’s effect on many cell enzymes, which affect metabolism and DNA repair. Medical experts will tell you that long-term exposure to arsenic, either in drinking water or any other source, can cause cancer in the skin, lungs, bladder and kidney. It can also cause other skin changes such as thickening and pigmentation, “ sources said.

“We are not saying KCM has not done anything about this. They have put up strict safety and protection measures and that’s why it is important that the mining firm tells the nation how it is handling this highly contaminated concentrate to allay fears because the four per cent of arsenic gas is too much for any mine in the world for smelting. Other means maybe must be explored.”

The sources said it was believed that the first consignment had a total quantity of 3,000 tonnes of copper concentrate and about 900 tonnes had so far been received.

And responding to a press query, KCM public relations manager Shapi Shachinda stated that arsenic content was common in copper concentrates.

“The concentrates contain some amounts of arsenic, which is a common component of copper concentrates, depending on their source. KCM has taken the necessary precautions to ensure that this and all impurities are captured and safely stored so that there is no adverse impact on the environment or human health,” Shachinda stated.

“The Zambia Environmental Management Authority (ZEMA) has been informed accordingly about the imports of the Chilean concentrates”
He said the concentrate is blended with KCM’s own concentrates and other third party concentrates.

“The company will smelt these concentrates in its Nchanga smelter. The source of the concentrates is the Chilean state-run Codelco, which is the world’s largest copper producer and was once the technology partner of the ZCCM,” Shachinda stated.

“The purchases are part of a programme that KCM is undertaking to ensure that it operates the Nchanga smelter at full capacity. With changes in regulations around VAT refund, it has once more become viable for KCM to purchase concentrates from other local and foreign mining companies and smelt them at its own facilities. Currently, KCM is blending its concentrates with those from mines in the northwestern province and the Democratic Republic of Congo. It is a common practice globally for smelters to buy concentrates where they have excess smelting capacity.

GEMFIELS sets another record at Lusaka Emerald auction

At least $14.5 million has been realized at the seventh Kagem local auction of precious stones held in Lusaka last month, Gemfields, has announced.

Chief Executive Officer Mr. Ian Harebottle said the stones auctioned were of lower quality rough emerald and Beryl from Kagem mine in Ndola rural.

“”We’ve set another record for realized per carat prices at an auction of lower quality emerald and beryl, and have now completed seven successful auctions in Zambia, all during the last 22 months.

It is pleasing to see a total of 88% of the total value of the lots placed on offer being bought and Zambian emeralds continuing to enjoy such firm demand.

Gemfields is increasingly becoming the supplier of choice for many of the world’s leading polishing and jewellery-manufacturing houses.

We look forward to our auction of lower quality Montepuez ruby in Jaipur later this month where we believe the market is as excited as we are to be a part of this first ever offering of such a considerable volume of non-domestic ruby rough in India.” Said Harebottle.

A total of 21 companies bid in what was the third Gemfields auction of Kagem emeralds during the current financial year (ending 30 June 2015). The auction was the seventh to be held in Lusaka, a practice which commenced in April 2013.

The auction saw 10.1 million carats of lower quality emerald and beryl extracted from Kagem placed on offer, with 19 of the 26 lots offered being sold, generating auction revenues of USD 14.5 million.

Kariba Minerals also participated for the first time in the Lusaka auction. The firm place an amethyst bid. Gemfields has 50 percent interest in Kariba Minerals.

This auction of rough amethyst from Kariba Minerals Limited (in which Gemfields has a 50% interest) was the first to be held within Zambia. Gemfields has hosted only one prior rough amethyst auction which took place in Jaipur in March 2011 and was used to test demand for amethyst in that market.

The amethyst auction saw 27.7 million carats of higher quality amethyst extracted from Kariba placed on offer, with 13 of the 14 lots offered being sold, generating auction revenues of USD 0.45 million. The amethyst auction realized an overall average value of 1.77 US cents per carat.

‘KCM’s indebtedness Chocking’

The fate of Konkola Copper Mine, a unit of London listed copper miner, Vedanta Resources Plc, remains uncertain in Zambia as the company is still indebted with other organisations, the latest being a staggering US$59 million owes to Zambia’ Consolidated Copper Mines Investment Holdings (ZCCM IH).

Last year, KCM, Zambia’s leading producer of copper and cobalt was embroiled in a contractual obligation with a power supplier to the mines on the Copperbelt.

The Copperbelt Energy Corp. which provides an average 530 megwatts of power to teh mines on the copperbelet daily, is owed by KCM in excess of US$44 million in commercial debt of which partial payment has been made and the full amount is yet to be settled, a move which caused production interruptions at some of its critical operations at its Chingola and Konkola mines.

There was no immediate comment from CEC’s spokeswoman Chama Kalima or KCM spokesperson Shapi Shachinda how much has been paid towards offsetting the US$44 million. However sources close to the miner say, the miner is struggling to offset the debt, although not yet paid in full.

This is because of various other obligations it needs to undertake, especially that it is also seeking to secure a refund in excess of US$200 million from Government through Zambia Revevenue Authority, owed in unrefunded Value Added Tax (VAT), like many other multinationals based in Zambia that are exporters.

A report by the Auditor General reveals that KCM is yet to resolve the US$59 million it owes the country’s holding company under a Settlement Agreement signed in February 2013.

The report on Accounts of Parastatal Bodies and other Statutory Institutions for the 2013 financial year states further that the mining company did not honour a Settlement Agreement signed between the two entities and has an outstanding balance due to ZCCM-IH amounting to US$59,684,655.

A Settlement Agreement had been signed on February 11, 2013, as a full and final settlement of all claims due under or pursuant to the Price Participation Agreement, which KCM had failed to honour previously, the report adds.

“KCM Plc agreed to pay ZCCM-IH amounts totalling US $119,744,655 over a period of four years in line with the payment schedule as follows: US$46,324,655 to be paid on or before August 31, 2013; US$73,420,000 to be paid on or before September 30, 2016 in accordance with the payment schedule,” part of the report reveals adding.

As of September 2014, KCM Plc had not honoured the Settlement Agreement and had only paid a total amount of US$16,500,000 out of US$76,184,655, which was due as of September 30, 2014, leaving a balance of US $59,684,655.

The report further indicates that although KCM failed to honour the Settlement Agreement, ZCCM-IH, on the other hand, also failed to trigger an enforcement clause stipulated in the Agreement.
The agreement stipulated that in case KCM failed to pay a deferred amount at the next instalment date, ZCCM-IH was permitted to take legal action for monies owed through the English courts or by arbitration in respect of the deferred amount and any interest that would have accrued pursuant to clause 5.

Contrary to clause 5 of the Agreement, as of November 2014, there was no evidence to show that ZCCM-IH had taken any legal action for monies owed.

ZCCM-IH has had “poor performing loans” with Ndola Lime Company Ltd, with the latter having failed to pay the former over US$7 million in an installment due last June. “On 29 July, 2011, ZCCM-IH signed a loan agreement with Ndola Lime Limited an amount of US $26,000,000., adds the report.

A review of the agreement repayment schedule and accounting records revealed that Ndola Lime Limited should have repaid a total of US$7,356,990 as at June 30, 2014. However, Ndola Lime Limited had not made any payments to ZCCM-IH as of August 2014 and ZCCM-IH had not enforced the default clause of the contract,”

Last year, the mining company, with a labour force of over 10,000 workers was embroiled in various debt obligations which also attracted bailiffs to seize property belonging to the company to recover what was due to them in various obligations.

Amid a US$44 million commercial debt with Copperbelt Energy Corporation, KCM was faced with another commercial obligation with Mitchell Drilling International of Australia which through their bailiffs pounced on the property it has in Acacia House in Lusaka demanding to be paid what was due to them.

According to the report by the Post newspaper, the bailiffs acting on behalf of their client besieged Acacia House to try and recover US$5 million owed to the drilling company for the supply of goods and services and demanded 10 percent interest.

This operation follows KCM’s failure to pay for the drilling services Mitchell Drilling rendered after the two parties entered into a contract signed on June 27, 2008. According to the agreement, the paper added, the contract ran between June 2008 and November 2011 during which Mitchell Drilling did surface drilling and reverse circulation at Konkola and Nchanga mines.

Mitchell drilling sued KCM in the Lusaka High Court for breach of contract and failure to settle the outstanding amount of 731, 546.31 Euros that had accumulated. On March 14, 2013, the Lusaka High Court entered judgment in favour of Mitchell Drilling International limited and Mitchell Drilling Zambia limited who were the plaintiffs in the matter ordering KCM to pay the said monies.

order for a lasting solution to the impasse between the miner and power provider, Copperbelt Energy Corporation which had earlier demanded to be paid US$$44 million in commercial obligations for power supplied to the mine.

Nonetheless, the Post reported, KCM had earlier contested the High Court decision by applying for an order for stay of execution pending hearing and determination of the appeal in the Supreme Court.
On June 23, 2013, the High Court granted KCM the said order subject to the mining company paying the judgment sum of K5, 830, 424 into an Escrow bank account within 30 days from the said date, the paper stated.

However, KCM appealed against this ruling arguing mining operations would be affected should they pay the colossal sum as ordered. On September 18, High Court judge Flavia Chishimba dismissed KCM’s conditional stay of execution and ruled that the mining company pays Mitchell Drilling the said outstanding amount with 10 per cent per annum interest., the Post added in its report.

As the KCM indebtedness continues to unfold, Zesco, the sole generator of power in Zambia claims the miner owes the utility in excess of IS$110 million in power supplied to the company, according to former Managing Director Cyprian Chitundu in a report to President Edgar Lungu recently.

KCM still owes ZCCM-IH over US$59m – report

KONKOLA Copper Mines still owes ZCCM-IH over US$59 million under a Settlement Agreement that was signed in February 2013, according to the latest Auditor General’s report. The Auditor General’s Report on Accounts of Parastatal Bodies and other Statutory Institutions for the 2013 financial year stated that the mining company did not honour a Settlement Agreement signed between the two entities and has an outstanding balance due to ZCCM-IH amounting to US$59,684,655. According to the report, a Settlement Agreement had been signed on February 11, 2013, as a full and final settlement of all claims due under or pursuant to the Price Participation Agreement, which KCM had failed to honour previously.

Murray & Roberts makes progress on synclinorium shaft sinking project

Murray & Roberts Cementation Zambia has reported the completion of the sinking of the Synclinorium Shaft project in Kitwe, Zambia for its client Mopani Copper Mines (MCM).

“The last blast of the Main shaft took place on 30 September 2014 with the shaft at a final depth of 1 280.85 m below the shaft collar,” Murray & Roberts Cementation Zambia Project Manager Neil Mackay, says.

The scope of work comprised a blind sink of a 7m diameter downcast lined shaft with a bulk air cooler level, two electrical cubbies and two stations. The equipping and commissioning of the shaft commenced at the end of October with the erection of a new headgear, winder and roping up the shaft scheduled for 2015.

The Murray & Roberts Synclinorium shaft team has worked closely with the Mopani Copper Mine Synclinorium Project team towards the common goal of helping the project reach the safe stage where it is today.

Noteworthy achievements at the Synclinorium Shaft project to date include a record 96 m of sinking and lining achieved for the month of August 2013 and a Lost Time Injury Free figure of 290 days to date.

A challenge to date has been the pumping of up to 24 000 litres of ground water daily from the shaft. This groundwater is pumped to the surface from where it is diverted into a settlement pond for treatment.

“We intersected a 28 m dyke, from 1 040 m from 1 068 m, and sank through it without incident, a notable achievement given that the rock is very hard and susceptible to scaling. This has necessitated support to within 1 m of the shaft bottom in order to increase worker safety,” Senior Project Manager Wyllie Pearson, says.

Equipment deployed on the project by Murray & Roberts Cementation Zambia includes stage and kibble winders, a five boom jumbo shaft drill rig, a five deck working stage with a cactus grab, two mini excavators and an automated batch plant.

All equipment is serviced in a comprehensive on site workshop by a well trained team to ensure operational excellence and adherence to strengent safety measures.

The current date for commissioning of the shaft is December 2015.

Murray & Roberts Cementation Zambia has also pioneered several health and safety innovations at the Syclinorium Shaft project. These include a new system to replace the old system of hand signals and pull bells to communicate from the shaft bottom to the working stage platform.

The new system consists of a radio installed in a worker’s hardhat, with a built in speaker and microphone to enable hands free operation. The shaft bottom signalling system allows the sinker at the shaft bottom to give the kibble winding engine driver signals from a hand held unit.

Electronic alcohol testing equipment has also been deployed to measure the blood alcohol levels of all workers entering and leaving the site. The system is linked to the entrance turnstile and will not allow a worker to enter if he is in violation of the zero parameter.

Another innovation has been the introduction of directional rope lights on the stage to indicate to all workers which direction the kibble is at any given time.

While the Synclinorium Shaft represents Murray & Roberts Cementation Zambia’s first project for MCM, subsequent similar projects managed from its Kitwe office have underlined the contractor’s excellent track record in the country.

The team is 1 084 strong, comprising accountants, human resources coordinators, training facilitators and raise bore, mining and engineering teams.

Of these 141 are expatriate workers, ranging from management to shaft sinking specialists. A full project management, shaft sinking, raise boring and development portfolio offering is provided by Murray & Roberts Cementation Zambia, in addition to training and technical support.

Murray & Roberts cementation continues to excel at Lubambe copper mine LTD

Murray & Roberts Cementation’s second contract, for the trackless high speed development at Lubambe Copper Mine in Zambia, has been extended by a further two-year period.

The Lubambe Copper Mine which is a joint venture between African Rainbow Minerals, VALE and Zambia Consolidated Copper Mines Investment Holdings, is expected to produce 45 000 tonnes of contained copper at steady state by 2015.

The current contract involves all horizontal development work using trackless high speed technology in Ramps 1, 2, 3, 4 and 5.

In addition, the Murray & Roberts Cementation team was also requested to undertake the vertical development of return airways, service raises and silos and maintenance work on the surface infrastructure, provided by Murray & Roberts Cementation on the first phase of the contract, will continue for the duration of the entire contract.

Murray & Roberts Cementation Senior Project Manager at Lubambe Wyllie Pearson, added that they will continue with several projects that were started under the first contract.

“We will continue the development of infrastructure for two conveyor belt systems and supply and install all temporary compressors and air piping reticulation necessary for the development works and diamond drilling section. Furthermore, we will install all temporary ventilation fans and ducting,” he said.

“We also operate and maintain the owner’s equipment fleet. Six Sandvik TH 540 dump trucks, four Sandvik LH 410 and one Sandvik LH 514 LHD, as well as nine Sandvik TH540 40-ton articulated dump trucks allocated to load and haul. Face charging is performed with three Getman emulsion charging units and the transport and lifting equipment consists of two Getman scissor lifts, a Fermel scissor lift and two Getman cassette handlers. A Fermel grader and Manitou 742 telehandler complete this fleet,” added Pearson.

Allocated to drilling are five Sandvik DS320 double boom split-feed jumbos, a DS320 fixed rail jumbo and a DS 420 long hole rig used for raise mining. The support and supervision vehicles are Toyota Land Cruisers, which have been converted to mining specifications.

“All maintenance work on this equipment as well as the Murray & Roberts Cementation equipment fleet is undertaken in our well-equipped on-site workshop by a highly experienced team of mechanics and technicians, to ensure optimised operability and uptime. All consumables are supplied by the mine,” he revealed.

Pearson said that the contract is characterised by a high level of cooperation between the Murray & Roberts Cementation and Lubambe Copper Mine teams.

“We have developed a mutually beneficial relationship that sees us providing our client with a ready and continuous supply of power and water handling facilities, to ensure efficient interaction within overlapping areas. In addition, the mine provides our team with rock bolts, split sets, mesh and cement, while diesel and lubrication oils are supplied as free-issue items.”

Since the extension of the first contract by 15 months, a total of 24 653 metres has been developed against a target of 23 458 m.

“We have made excellent progress to date and met every one of our scheduled targets. The two main underground tipping arrangements consisting of four tipping points and two silos were completed and commissioned within the scheduled construction dates. A mineral sizer was installed and commissioned ahead of schedule on the tips,” Pearson said.

The six level crusher chamber was rehabilitated and supported with welded mesh and 6 m cable anchors, with the crusher and equipment in place. In order to assist with the main return air system, a series of ventilation raises were developed from the ramp 3 225 Level and two 225 kW surface fans installed and commissioned.

The project has not been without its challenges. Some parts of the Lubambe ore-body can only be accessed by mining through a very weak zone of sand-like material. The sand zone developing and support project comprises four successfully completed sections with a fifth in progress.

These sand zones require specialised support methods developed specifically for Lubambe and are similar to civil tunnelling support methods. Pearson explains that this has been effectively achieved by using Titan soil nails, Becker Arch Sets, 5,6 mm welded mesh and shotcrete as support mediums. Sand is excavated out of the face using a Hyundai 35Z7 mini excavator.

At the request of the client, a drop raising programme was undertaken, with 12 345 metres completed concurrently with contractual development.

Pearson expressed belief that the success of the project to date can be attributed to a number of factors, including the creation of a highly efficient team of experienced and multinational operators, supervisors and management, mostly with previous expatriate experience. The drilling team is a mixture of Australian decline mining specialists and Filipino and South African expats.

The team comprises 405 employees, with approximately 12% expatriates. The Zambian national component of the team is made up of HR staff, surveyors, accounts and administration staff, skilled operators, officials and workmen. The expat component of the crew consists of site management, safety and training staff and expert miners, operators and maintenance staff.

Similarly, training plays a big role in ensuring that the requisite regulations and quality standards are achieved and maintained.

“The training at Murray & Roberts Cementation’s Bentley Park facilities included trackless mining modules. The nature of the ore bodies in Zambia is such that most of the mining is fully trackless, with the exception of the haulage levels. There is a vast pool of fully trained and experienced mine workers available to recruit from, which has greatly simplified the human capital element of the project,” Pearson pointed out.

He said there was a successful transformation from a small highly skilled decline sinking crew, to a team responsible for ore and main development, sometimes in remote and scattered areas of the mine.

Employees also have access to a modern e-learning centre which has been opened at Murray & Roberts Cementation’s Synclinorium shaft sinking project in Kitwe

“This centre provides the same high quality standards as the Bentley Park facility in South Africa. The comprehensive Murray & Roberts electronic library and learning system is available for learners and facilitators alike,” quipped Pearson.

Appropriate and successful training is reflected in the safety record achieved on site, with no Lost Time Injuries (LTI) recorded for the first year. There have also been no fatal incidents on the contract to date, a noteworthy achievement given the nature of the project.

The award of the Synclinorium shaft sinking project, as well as the shaft sinking and development of the Mufulira Deeps project are a true reflection of the company’s reputation in the region.

In addition, Murray & Roberts Cementation’s Raise Boring Division is presently operating in Kansanshi, a further indication of the significant growth in the company’s presence in Zambia.

“Murray & Roberts Cementation has demonstrated complete commitment to its Zambian projects through the formation of a Zambian division with corporate offices situated in Kitwe. We are presently able to offer prospective clients a full shaft sinking and development portfolio, including training and administration from Zambia, with the benefit of technical and logistical support from Murray & Roberts Cementation in South Africa,” Pearson said.
