July - August 2020Editorial Note

Another storm hits the industry ver the past two years, the mining industry has either fought tax issues wars or government’s heavy hand on its operations in vain.

Another storm has strike. COVID-19 has hit miners in the first half of the year and pro-jections into the year are not looking good either.

Just like our previous observation, the grass suffers – workers, communities and the startups in the mining communities bear the brunt.

Indications have already cited that in Febru-ary, March and April, the mining companies’ revenues plunged by around 30 percent, due to COVID-19 pandemic. The compa-nies’ burden will be extended to a broader community that relies on its existence and eventual hitting hard on the most vulnerable – women, children and the youth.

At this junction, it is also worthy calling out for a state bailout, miners need cushioning, and the benefits will surely trickle down to communities.

For the several years that government and the mining community have spent at log-gerheads, more solutions should have been created to build a strong buffer for the econ-omy and companies in the mining sector.

Sitting on the fence and failing to conclu-sively decide on some of the challenges

that negatively affected growth of the min-ing industry is only rearing its ugly head now.

With huge problems of COVID-19 staring at the private sector and government, the red flags and the bells that we rang in the past should not have fell on deaf ears. Preaching sustainability has passionately been part of our DNA, simple because it is the right thing to do. Every venture needs those sustain-ability echoes to be louder and clear, yes sometimes the future is not predictable but its better when it finds people with some-where to fall on.

Now like always the grass suffers, the workers will lose jobs, families will be dis-integrated , several startups will crumble, anticipated developments and support to national programmes will come to a sudden halt, yet this respiratory disease could have only slowed down the wheels of produc-tion, the impact will be unpleasant.

We hope leaders listen to our calls for future benefits. We need change and a positive change.

July - August 2020News Briefs

2021 CAMINEX preparation ongoing

With a reputation as the trade show that delivers innovation and opportunity, CAMINEX returns in 2021, taking place from 1-3 June 2021 at the Kitwe Showgrounds in Zambia.

According to the organisers CAMINEX is the essential trade platform for the Copperbelt region, located in the heart of the Copperbelt.

The mining giants are urged to get face-to-face with customers and fast-track business growth on the Copperbelt through ex-hibiting and reaching the greatest number of decision-makers in a specific target market in the shortest space of time.

“The show enjoys unequivocal local support as it is hosted in conjunction with a local partner and is attended and endorsed by local government. This support influences increased atten-dance from the mines and creates valuable local media expo-sure.”

CAMINEX 2020 postponed

Organisers of CAMINEX 2020 (Copperbelt Agricultural Mining Industrial Networking Expo) regret cancelling of the annual mining jamboree.

London Mwafulilwa, CAMINEX Chairman said the postpone-ment was in line with the directive from the Minister of Agricul-ture with regards to holding Agricultural Shows and also the government’s guidelines on the COVID-19 Pandemic.

Mwafulilwa said CAMINEX remains an important event for the Copperbelt of Zambia and brings together a number of local, regional and foreign exhibitors and visitors.

“In light of the spread globally of the COVID–19 Pandemic, we believe that in the interest and safety of all our partners, we have no option but to postpone CAMINEX 2020 to the new dates set at 1st – 3rd June 2021,” Mwafulilwa said.

The Show Society Board believes that by moving the date by one calendar year, will enable everyone time to settle and pre-pare for CAMINEX in 2021.

Mwalufila said the Show Society will hold and honour all pay-ments already made for 2020 in 2021 without any price adjust-ments.

Cushion mining industry

The Zambia Chamber of Mines has urged the government to help cushion the industry from the impact of COVID-19.

The chamber submitted a broad three-phase economic plan to the government, to help it manage the effects of the pandemic.“Since then all mining industry stakeholders have been hoping that some significant stimulus measures would be instituted, as is being seen across the world,” it said.

The proposal includes immediate relief measures that could be followed by an emergency support package with financing that could be sought from the IMF and World Bank.

“This was with a view to providing some guidance to govern-

ment on the critical areas to be urgently addressed,” the state-ment said.

Jubilee team up with Tanganika

Jubilee Metals Group has secured the rights to about 150 mil-lion tonnes of surface tailings with contained copper to be up-graded at site and refined at its Sable refinery in Zambia.

The company obtained the rights for the material via its Brae-more Holdings subsidiary, by entering a joint venture with min-ing rights holder Star Tanganika.

“The magnitude of the secured copper tailings resources and related project offers a long-term sustainable earnings profile to Jubilee’s Zambian business,” the company said.

Jubilee Chief Executive Officer, Leon Coetzer said teaming up with Tanganika lines up with Jubilee’s strategy to take on a leading role in surface tailings processing in Zambia through the application of its technical expertise.

Villagers invade Mopani Copper Mine

Voice of the Vulnerable organisation has led over 3000 people to invaded land belonging to Mopani Copper Mine in Kitwe.

The invasion is amid Mopani Copper Mine’s Public Relations Manager, Nebert Mulenga warning encroachers to abandon the land.

Indications are that the group has since started clearing the over 300 hectares of land a few kilometers away from Mopani’s tailing dams.

Peter Malama, Voice of the Vulnerable Chairman is already leading the group in sub-dividing the pieces of land, citing that the piece of land does not belong to the Council.

He said some people are just claiming that the land belongs to Mopani to stop them Malama said his group is allocating the land to the vulnerable community at only K200 while the elderly are being given land for free.

Youth urged to embrace mining skills

Luanshya District Commissioner Patrick Maipambe has chal-lenged youth to take China Nonferrous metal mining training serious.

He said the youth should acquire knowledge and become a skilled labour force in the country and the Southern African region as a whole.

“The Chinese training is of high quality in terms of technology and other skills,” he said.

Maipambe also said that the Chinese-owned mine has been very active in fighting the spread of COVID-19 through the do-nation of assorted items to fight the pandemic.

The youth skills training programs in Luanshya district support-ed by the China Nonferrous metal mining are expected to cre-ate jobs for the stakeholders in the mining district.


July - August 2020Cover Story

ver the three months - February, March and April, mining companies’ revenues have plunged by around 30 percent, as COVID-19 pandemic unravel.

The Zambia Chamber of Mines announced that COVID-19 pandemic has cut the min-ing companies’ copper sales as a result of a disruption in the mining supply chain, which facilitates the export of the red metal to for-eign markets.

Statistics released by the Chamber reveals that the severe global restrictions on move-ment have wreaked havoc on the mining supply chain, and hindered the export and

COVID-19 heavily dents the mining industry

O sale of copper, and that the copper price collapse early in the crisis, though has since strengthened, is still down on average by 12 per cent over the period when compared to 2019.

According to the data industry, royalty pay-ments are estimated to have come in at approximately US $60-65 million over the three months, rather than the US $90 million that could have been expected.

In addition, the figures illustrate how close-ly government revenues mirror the fortunes of the mining industry. The Chamber chief executive officer Sokwani Chilembo said that mining companies had, however, per-

formed well in maintaining production amid the COVID-19 crisis.

“The industry has done a magnificent job of maintaining production over this difficult period. But, for various reasons, revenues have fallen massively. Zambia’s miners have been battling even higher costs for years, and we are concerned about the potential consequences of such a big hit to earnings occurring now,” said Chilembo.

Chilembo said the Chamber hopes that some of the revenue pressures may ease in the months to come, though the industry is unlikely to be entirely free of them for at least 12 months, and quite probably longer.

THE NEXT GENERATION OF ROAD ANDWATER INFRASTRUCTURE


July - August 2020Local News

nternational advisory firm Marlow Strategy has painted a bleak forecast for the country’s mining industry based on recent development in the sector.

Simon Wolfe, Managing Director of international advisory firm Mar-low Strategy’s first red flag is that the local mining industry is ranked in the bottom 10 of the 76 participating jurisdictions in the world for mining investment, according to the Fraser Institute’s 2019 annual survey of mining companies, published in February 2020.

According to the survey the steep decline was attributed in part to regulatory inconsistencies, as well as an unfavourable taxation regime.

Wolfe further bemoans why the ministry of Mines & Minerals De-velopment changed the system for export permits for minerals on June 10.

According to the changes the ministry will no longer accept sam-ples submitted to the geological survey department in Lusaka be-cause its believed exporters are submitting low-grade samples to the chemistry laboratory, undervaluing the value of mineral exports and affecting state revenues negatively. From July 1, ministry of-

ficials will be going directly to the mine sites and warehouses to collect the samples.

The permanent secretary Barnaby Mulenga said it is the desire of the government to gain full oversight of the mineral supply and val-ue chain to ensure effective monitoring of mineral production and exports. Wolfe however warns that an over-encroachment by the government or government-owned or controlled “private entities” is having a real-world negative commercial impact.

“We are seeing this play out now in the dispute between the Cop-perbelt Energy Corporation (CEC) and the state-owned Zesco and KCM. This has escalated so quickly that observers were shocked by the government’s unashamedly inappropriate intervention in ex-propriating CEC’s infrastructure through a statutory instrument and protecting an indebted company,” Wolfe said.

He said the developments and others are reasons to keep an eye on Zambia, including concerns over a breakdown of the power supply and the country’s inability to pay for electricity imports, which could push it further towards debt distress. Wolfe said the breakdown of the rule of law in neighbouring Tanzania, and the effect this has had on its economy, should also set off alarm bells for Zambians.

Analyst condemn government’s action in the mining sector

July - August 2020Opinion

have learnt that ZCCM-IH has decided to dissolve Ndola Lime and form a New Company out of the assets called Limestone Resources.

Ndola Lime was practically insolvent; it had liabilities of more than K1bn, accumulated over the last eight years.

This is a company at its best was bringing in revenues of K70m/yr and running losses after tax of about K200m/yr.

It had to take two former employees to stop this incompetence, corruption and delin-quency. They (two) instituted, in Sept 2018, business rescue proceedings in the Lusaka High Court pursuant to the Corporate Insol-vency Act No.9 of 2019.

The brains at ZCCM-IH have now dissolved Ndola Lime and formed a new company, claiming that they have wiped away the liabilities thus giving it a clean slate. The new company is 100 percent owned by ZC-CM-IH just like Ndola Lime was.

My question is: who is going to pick up the K1bn debt seeing that there is no new mon-ey coming into this company? Is this a way of just putting a new label on spoiled milk and expecting unsuspecting customers to buy it?

I think it’s time certain directors were de-clared delinquent or the circus continues. Another circus is KCM, what is the way for-ward?

“I’ve found you a Buyer” - declared Presi-dent Mwanawasa upon arrival from his visit to India, somewhere in 2003. By November 2004 the Indian company Vedanta Resourc-es had bought the majority stake (51 per-cent) in KCM. In 2008 they increased the stake to 79.5 percent.

Vedanta had just listed on the London Stock Exchange just before they got KCM. I don’t know which mining technical and financial experts had accompanied our good Presi-dent on this trip. We know that our govern-ment at the time was under pressure from the IMF because of the small issue of HIPC completion date.

Who did the due diligence on the Vedan-ta/KCM, please step forward?

What did Vedanta find at KCM on Day 1?

1. Debt free operation

Authorities stop the circus in the mining industry By BRAVE MUSHIKITA*

I 2. KCM had US$60m in the bank3. KCM had a month’s supply of finished copper(150k) on the way to the customers but not yet paid for.4. KCM had 2-3 year caved reserves at Nchanga U/G mine5. KCM had 2mt of copper and 1mt of cobalt ore of stockpiles at Nchanga Open Pit and large quantities of ores already exposed at Nchanga and Konkola U/G6. KCM had Chingola Refractory Ore with 150kt of acid soluble copper stockpiled on the surface7. KCM had already done the detailed feasibility study of the Konkola Deep Mine Project, the would be flagship mine for the company.

All Vedanta needed on top of the treasure chest they had found at KCM was six tonnes of finished copper to fully pay for the Konkola Deep Project

What did Vedanta do in the last 15 years at KCM?

From the onset they had only interest in the short-term life of mine and little interest in medium to long-term life of the property. Their investment was tailored only for short term purposes.

During this period KCM focused on treating the ores mined by previous management they never developed any plans to carry out any meaningful Primary development in the Open Pits, UG mines at Nchanga and Konkola.

Its open secret that during the early days of cheap ores and high metal prices KCM was minting money and most of it left the coun-try. They exhausted all the ores from stock-pile, dumps and exposed ores and they had NO WHERE TO GO OR HIDE.

KDMP and the U/G Upper Ore Body (UOB) was not developed because of lack of req-uisite mining knowledge, skills and in depth understanding of the two projects. UOB was abandoned because of costly mistakes made.

KDMP was delayed, estimated to be at peak production by 2010, the shaft was only finished in 2012/13 to 900ML(should go to 1500ML). They instead banked on the Nchanga smelter and the TLP to be mak-ing money for them through toll treatment or outright purchases of copper and cobalt concentrates, unfortunately this did not ma-

terialize as expected.

Its 2020, Vedanta Have Been Run Out Of Town, Where To Now?

My proposals:

1. Allow KCM to import copper concentrate duty free from anywhere in the world in the short and medium term to fully utilise the smelter, extend this to acid soluble ore for TLP.

2. Find a credible developer for KDMP with proven track record, technically and finan-cially. Let’s talk earnestly to the Swedish for partnership in this venture.

3. Give Maamba colleries a stake in KDMP worth 620GWh/yr of power(that is how much power would be needed to pump out about 400km3 of water per day to mine out 210kt/yr of copper metal when KDMP is ful-ly developed).

At this point we can no longer afford another cook up, peoples’ livelihoods and lives are at stake. This is where I end with free infor-mation, if you are interested to get more my phone is on the hook, I charge per minute.

rident Resources, soon to be renamed Trident Royalties, entered into a gross revenue roy-alty (GRR) with Moxico Resources in ex-change for a cash consideration of US$5 million and Trident is entitled to royalty pay-ments on production commencing from the 1st of July 2020 and extending in perpetu-ity.

Moxico will use the proceeds of the trans-action to fund the continued ramp-up of the Mimbula mine, as well as for general work-ing capital purposes. Royalty payments to Trident will be made on a quarterly basis.

Moxico has a highly experienced board and management team led by former Rio Tinto chief executive Alan Davies, who has assembled a strong team of proven mine operators with significant experience in the Zambian Copperbelt.

Mimbula has a significant JORC (2012) compliant measured and indicated resource of 69.8 Mt grading 0.96 percent total cop-per (TCu) for 668 000 t of contained copper

Trident Resources acquire royalties at Moxico Resources

T and an inferred resources of 14.2 Mt grad-ing 0.92 percent TCu as at August 2019.

The asset is currently ramping-up produc-tion, having sold its first London Metal Ex-change registered Grade A copper with a 99.99 percent purity in June 2020.

The GRR is applicable to production from the Mimbula mine, comprising of 100 per-cent of production from licences 21816-HQ-LML (Mimbula), 8440-HQ-SML (Zuka), and on 50 percent of the production from li-cence 8514-HQ-SML (OB18). The licences collectively cover 1 271 hectares.

The GRR rate will be 1.25 percent, decreas-ing to 0.3 percent upon $5 million being paid on the royalty, with a subsequent de-crease to 0.2 percent once the royalty has been paid on 575 000 t of copper.

If, in a given quarter during the minimum payment schedule period, Moxico makes GRR payments in excess of the quarter-ly minimum amount, it may carry over the excess amount to any subsequent quarter

in which the GRR amount is less than the minimum payment schedule amount.

“We are delighted to announce the acqui-sition of a cash generative royalty over the Mimbula Mine, a long-life asset with favour-able production and cost profiles,” said Tri-dent Chief Executive Officer and Executive Director, Adam Davidson.

“The royalty will provide our investors with exposure to an attractive commodity pro-duced from an asset located in a prolific re-gion in the Zambian Copperbelt, operated by an experienced management team.

“In addition, the royalty is structured attrac-tively such that Trident will rapidly recover its invested capital, while retaining long-life exposure to the growth of the asset. We are very pleased to have concluded trans-actions on two cash generative royalties within a short time frame and I look forward to reporting further on our progress as we continue to build a diversified portfolio of mining royalties and streams,” Davidson said.



hy does CEC enter into long-term power supply agreements?

In the electricity industry, it is a normal prac-tice to have long term agreements (some-times known as power supply (PSA) or bulk supply agreements (BSA)), often between 15-25 years. This is because an investor needs a significant capital outlay to build power infrastructure, which capital is usual-ly borrowed from lenders (both commercial and development banks).

The repayment of these loans is over a long period, typically 10 -15 years. Therefore, the lenders want to be sure that the borrower will be able to pay back the loan and a long-term agreement between the generator or supplier of the power and the buyer is nec-essary to give the lenders comfort that the loan will be repaid. In fact, as everybody in the sector knows, the practice is that lend-ers demand and scrutinise copies of the power supply agreements and if necessary, will insist on changes to their tenure in or-der to match the loan period. Of course, it is critical that the buyer is credible and able to settle bills over the duration of both the PSAs and loan agreements.

In the case of CEC, its mine customers re-quire the comfort of reliable and continuous power supply to support their long-term investment decisions, typically associated with mining.

Power contracts protect the interests of both the supplier and the buyer (customer), not least in terms of committed offtake on the one hand and security of supply on the other.

Does CEC buy power from the national utility at uneconomic tariffs?

The tariff CEC pays for the power it gets from the national utility has periodically been revised upwards over the course of the supply agreement between the two.

Contrary to claims that the tariff has re-mained low since 1997 and that ZESCO’s retail customers pay more than the mines, and that CEC has received a disproportion-ate share of the mining power supply rev-enues.

Over the years, all stakeholders (mines, ZESCO, CEC, government) have come to-gether with respect to getting a mining tariff that is beneficial to the continued sustain-ability of both the power sector and the

Twelve questions on tariffs, power supply agreements and restrictionsW mines. Therefore, stakeholders successful-

ly negotiated and implemented upward ad-justment to mining tariffs of 35% and 28% in 2008 and 2011 respectively, guided by the ERB Cost of Service Study of 2006.

Another tariff increment was negotiated and agreed by stakeholders in 2017. Overall, between 2008 and 2017, the tariff increased by a factor exceeding 300%. These tariffs are not set by CEC but are an outcome of negotiation involving all relevant parties and regulated/approved by the Energy Regula-tion Board. The tariff structure has always been such that the larger share of CEC’s revenues from electricity sales to the mines is paid to its supplier, ZESCO.

There is currently going on a Cost of Service Study to inform electricity pricing so that all electricity consumers at the various points in the value chain will pay tariffs that are expected to be cost-reflective. The study, being spearheaded by the regulator, is ex-pected to be finalised by the end of 2020.

What is a power supply restriction?

A power supply restriction is the action taken by a power utility to limit the amount of power supplied to a customer, usually arising from the customer’s failure to meet its obligations/settle its bills within the con-tractual timeframe.

Does the law allow power supply restric-tion?

Yes, section 43 of the Electricity Act, 2019 states that where a person fails or refuses to pay a charge for electricity (bills) under

a contract of supply (supply agreement) or engages in an act likely to affect the safety, reliability, security or correct record of elec-tricity supplied, the licensee may discontin-ue the supply of electricity under a contract of supply and cut off or disconnect (in this case power supply restriction) any electric line or other equipment through which the electricity may be supplied.

What is the objective of restricting power supply?

The sole objective of restricting or reduc-ing a customer’s power supply is to com-pel the defaulting customer to settle their debts and not to cause sabotage. As such, in the case of CEC’s mine customers, only the production functions are targeted and done in a well-considered, planned process undertaken not arbitrarily but with the full involvement of the customer, ensuring the safety of personnel and equipment, and leaving the minimum amount of power re-quired for purposes of safeguarding per-sonnel and the mine’s assets.

What leads to a power supply restric-tion?

A power supply restriction is usually carried out when a customer fails to settle electric-ity bills within the settlement period speci-fied in its supply agreement or contract of supply with the provider of electricity.

How is a power supply restriction carried out?

A power supply restriction, as a measure of last resort, follows a meticulous and con-


July - August 2020

sultative process between the customer and the utility. A notice, within a stipulat-ed time frame and pursuant to the supply agreement in place between the parties, is issued to the customer. If the customer fails to honour their obligation/pay the outstand-ing bill within the stated time frame/grace period, the utility engages the customer to discuss modalities of the restriction, a pro-cess intended to safeguard the safety of the mine and people. Restriction means a reduction in the level or amount of power a customer normally receives; it does not mean a complete cutting off of supply. The customer is always left with sufficient pow-er for purposes of safeguarding personnel and the mine’s assets.

What steps are taken to ensure safety during a power restriction?

Contractually, before restricting power to a customer, the technical teams of both the utility and the customer meet to agree on the restriction modalities to ensure that em-ployees of the mine and its equipment at all times remain safe. A power supply restric-tion will not take place without the partic-ipation of the customer, as such, circuits/loads to be switched off are agreed by both parties.

An all-inclusive power restriction process ensures preservation of the safety of mine equipment and personnel. Restriction means a reduction in the level or amount of power a customer normally receives; it does not mean a complete cutting off of supply. The customer is always left with suf-ficient power for purposes of safeguarding personnel and the mine’s assets.

When a power supply restriction is ef-fected, is the supplier still obliged to provide emergency power supply to the customer?

The provision of emergency power supply is dependent on the level of the restriction in effect. Depending on the level of power re-striction, a customer under restriction may receive emergency power.

When can a power supply restriction be lifted?

A power supply restriction is lifted when the customer satisfies the conditions set by the utility in the notice to restrict power supply given to the customer prior to the restric-tion being effected or by agreement of the parties on the terms and conditions under which the restriction may be lifted. This may include immediate settlement of the outstanding power bill(s) upon which the restriction was made and committing to an enforceable payment plan to liquidate the outstanding power bill(s).

Is CEC a “middleman”?

Picture this: does an oil marketing company need to own an oil field to sell fuel or should a supermarket grow maize for it to sell mea-lie meal?

Generation, transmission, distribution and supply make up the four main segments of any power sector value chain, and a play-er can operate in one or more of the seg-ments. One need not necessarily operate in all segments of the chain. One can exclu-sively generate power as an independent power producer while another can operate as a transmission and distribution compa-ny, as in the case of CEC and North West-ern Energy Corporation. Each segment of the value chain requires capital investment, and specific expertise to build and operate its infrastructure while contributing to the whole power sector and its growth.

The modern electricity industry is tending towards operating as separate entities in the various segments. You see this in the developed economies of the world where it has almost achieved perfection. Closer to home in Zimbabwe, Malawi and Angola the power sector is partially unbundled to vary-ing extents with generation on its own. In South Africa, a similar but more far-reaching process has just begun and is projected to be completed in the next three years. With the examples of CEC, North Western Ener-gy, Maamba, Lunsemfwa and Ndola Ener-

gy, and many others in the making, one can only delay an inevitable process for that is how modern power systems are organised.

It is informative to note that one prerequisite for generation projects to take off in south-ern Africa as elsewhere is the availability of (reliable) transmission infrastructure to evacuate the power in bulk to the consump-tion centres. For example, Maamba’s coal plant would never have been built if trans-mission lines were not available nearby and there was no off-taker (buyer). The Kariba dam complex itself and transmission lines to the Copperbelt were built in the 1950s mainly to service the needs of the mines on the Copperbelt. The reliable market provid-ed by CEC’s predecessor through its well developed infrastructure was sufficient to underpin the huge loans that the Federal government needed to source from interna-tional lenders to finance the complex and the associated bulk transmission lines to evacuate or move the power to the main load centre on the Copperbelt.

Is CEC profiteering from infrastructure it undeservedly owns?

Development of CEC’s infrastructure dates back many years to the 1950s.

A consortium of mining companies on the Copperbelt formed the Rhodesia-Congo Border Power Corporation (now CEC) in the early 1950s as a privately-owned pow-er utility. The Company has existed under different names (i.e. Rhodesia-Congo Bor-der Power Corporation, Copperbelt Power Company and ZCCM Power Division during nationalisation from 1986). It was later in 1997 reverted to a private company, post ZCCM privatisation.

The reasons for forming the Company in the 1950s were as true then as they are today: a company specialised in power sourcing and distribution to the mines using infra-structure designed with inbuilt reliability and security of supply to serve the peculiar needs of the underground and wet Copper-belt mines.


July - August 2020Feature

espite the COVID-19 impact that has lead to the postponement of the CAMINEX 2020, organisers of the oldest agricultural, mining, engineering and construction sectors jam-boree remains optimistic.

“Having built a reputation as the trade shows that delivers innovation and op-portunity, CAMINEX returns in 2021, tak-ing place from 1-3 June 2021 at the Kitwe Showgrounds in Zambia,” said London Mwafulilwa, CAMINEX, chairman.

Organised by Specialised Exhibitions, which is part of the Montgomery Group with a proud heritage spanning over 50 years, CAMINEX offers a refined platform for miners, farmers and construction players. Mwafulilwa remains upbeat that CAMINEX is the essential trade platform for the Cop-perbelt region, located in the heart of the Copperbelt.

Some of the highlights to lookout for at CAMINEX 2021 include free-to-attend sem-inars, premier visitor lounge, new product display showcase, 1000’s of innovative products and much more.

CAMINEX is the essential trade platform

D The show also boasts of exhibitors with un-paralleled access to an audience of buyers with high purchasing power.

“Visitors are drawn to the show by its un-rivalled showcase of the latest industry products, equipment and services,” said Mwafulilwa.

Various exhibitors at the event will include earthmoving equipment, SHE equipment, supplies and technology, agricultural ma-chinery, equipment and supplies, major banks, venture capital and project finance firms

In addition, bulk materials handling equip-ment, storage & materials handling sys-tems, general engineering and manufactur-ing, electrical engineering equipment and supplies, leading-edge mining technology, machinery, equipment and supplies.

The list of exhibitors also includes gener-ation, transmission and distribution, sus-tainable energy and applications on water filtration, coupled with those providing fixed mobile and satellite infrastructure and ser-vice providers.

He reiterates that through CAMINEX, the different industries – mining, agriculture and construction gets a face-to-face opportuni-ty with customers, fast-tracking their busi-ness growth on the Copperbelt.

“Exhibiting is the most cost-effective way of reaching the greatest number of deci-sion-makers in a specific target market in the shortest space of time,” said Mwafulil-wa.

He said the show enjoys unequivocal local support as it is hosted in conjunction with a local partner and is attended and endorsed by local government.

“This support influences increased at-tendance from the mines and creates valuable local media exposure.”

Mwafulilwa has challenged several min-ing companies to use the CAMINEX 2021, as an opportunity to generate sales, gain valuable sales leads, and develop business connections. “CAMINEX is a unique brand with so much to offer. Do not miss out on this Copper-belt calendar highlight,” emphasized Mwa-

fulilwa. This year’s postponement of the CAMINEX is in line with the directive from the Minister of Agriculture with regards to holding exhibition shows and also the gov-ernment’s guidelines on the COVID-19 pan-demic.

According to the organisers, CAMINEX is an important event for the Copperbelt of Zam-bia and brings together a number of local, regional and foreign exhibitors and visitors.

“In light of the spread globally of the COVID–19 Pandemic, we believe that in the interest and safety of all our part-ners, we have no option but to postpone CAMINEX 2020 to the new dates set at 1st – 3rd June 2021.”

In addition, the Show Society Board be-lieves that by moving the date by one calen-dar year will enable everyone time to settle and prepare for CAMINEX in 2021.

Over the years various exhibitors and visi-tors have attended the CAMINEX show and shared testimonies indicating the growth of the show and its importance to the mining industry.

Mirko Steinhage of Spectrometer Technol-ogies commenting after attending the 2018 show said: “Caminex 2018 has been anoth-er positive experience for us, the chance to meet up with existing customers in one place makes doing business very easy. It also gives us the chance to introduce our-selves to new potential customers. The show was well run and we look forward to 2019.”

Another happy customer, Anton Behm of Tru-Trac Rollers Conveyor Technology said: “Thanks for a great show! The last couple of days has been a refreshing experience. Thanks to all your staff for their hard work, nice to see professionals at work. Your company is known in the mining industry

as the market leader. We have seen many new faces but still the same level of good service.”

Meanwhile CAMINEX 2021 will be a trade only event and NOT open to the general public and students will not be permitted entrance under our general admission cri-teria.

“If you are a student looking to attend please contact us for further informa-tion,” said Mwafulilwa.

The show is also expected to offer import-ant value to both Zambia and the DRC’s rich mining belts as it is positioned in the heart of these adjoining areas. The Cop-perbelt Province and its neighbour to the North West Province form Zambia’s major industrial hub and significantly contribute to Zambia’s ranking as the second-largest copper producer in Africa and a top ten global cobalt producer.

NON-DESTRUCTIVE TESTING (NDT)

Industries are demanding higher product quality and reliability. Non-Destructive Testing of materials, components and structures can help to achieve these aims.

In its more traditional role, NDT technology can locate cracks and other material defects that might jeopardize the performance of the Plant, Pipelines, Engines, Vehicles and all manner of engineering components.

The range of techniques that are be used for Non-Destructive Testing is extremely wide.

Alfred H Knight (Zambia) Ltd provides expertise of inspection in the following techniques:

• Radiography Inspection• Ultrasonic Thickness Testing • Magnetic Particle Inspection • Liquid Penetrant Inspection • Ultrasonic Flow Detection

AHK Zambia is ISO/IEC 17025 accredited in all of these services.

CCM IH has announced the appointment of a Business Rescue Administrator (BRA) who would oversee the much need turnaround of Ndola Lime.

The BRA had commenced the process of restructuring the operations of NLC with a view to creating a business that will take over the running of the limestone oper-ations sustainably. With over one billion kwacha already sunk into the lime company over the last 10 years, the entity continued making losses from operations.

According to year on year annual reports from ZCCM IH in the last 5 years, indica-tions of the causes of the challenges the en-tity was facing emanated from its core asset (Vertical Kiln).

In a statement, ZCCM-IH Spokesperson Loisa Mbatha clarified and said that Ndo-la Lime Company has ceased to exist due to huge debts and a new company known as Limestone Resources Limited has been created. “Over the past 8 years Ndola Lime

Z Company Limited (NLC) accumulated an in-surmountable amount of debt, in excess of K1 billion, owed to various statutory bodies as well as private creditors, which led to the Company being technically insolvent,” Ka-koma said.

Kakoma said the main objectives of the restructuring plan are for NLC’s successor company, LRL, to commence operations on a clean slate, debt free, recruit a new man-agement to spearhead the re-orientation of strategy and operations without any legacy problems associated with NLC.

“The achievement of the objectives above would enable effective recapitalization of the business. In order to preserve jobs, a recruitment exercise for LRL will commence beginning August 2020.”

“The proposed restructuring plan ensures the continuation of NLC’s business, albeit under a different. ZCCM-IH is currently in the process of obtaining statutory and other approvals to facilitate the transition of NLC to LRL. The processes of approvals, trans-

fer, recruitment and recapitalization will take approximately six months from August 2020.

She said ZCCM-IH remains committed to revamp the operations at NLC, under a new entity and brand, and the proposed restruc-turing plan provides practical solution to the key challenges currently faced at NLC. The new company is a vehicle that is being used as part of the road map to financial health. The management team is well aware that there was need to start life anew for this segment of their portfolio and hence why the NewCo has been incorporated and is known as Limestone Resources Limited (LRL) 100 percent owned by ZCCM-IH.



AMINEX is Zambia’s mining, agricultural and industrial trade expo, which is positioned to in-crease the presence of Zimbabwean prod-ucts and services into the country’s mining sector.

According to Trade Map, the local econo-my’s import bill for mining supplies in 2019 was around US$333 million, with the largest suppliers being South Africa, Japan, China and India.

Given Zimbabwe’s proximity to Zambia, there is room to increase the contribution of local companies to Zambia’s mining sup-plies import bill.

The mining activities in Zambia’s Copper-belt region provide opportunities for local companies that can supply products such as safety clothing, fast moving consum-er goods, iron and steel products, electric transformers, pumps for liquids, silo main-

ibo Energy has concluded a £1 million funding facility, to continue development of diverse energy project portfolio comprising 1255 MW generation capacity ap-proaching commercialisation, to address the acute power deficits in Sub-Saharan Africa and the UK.

According to the company, primary focus will be on Benga in Mo-zambique, where it hopes to deliver 350 MW to 400 MW. Kibo has 65 percent interest in the Benga Power Plant Project and is backed by both the Mozambique government and the local energy compa-ny Termoeléctrica de Benga S.A.

In addition, the company has reported headway in Tanzania, where it is awaiting further guidance from authorities regarding a new ten-der for coal fired power projects “Following the recent EGM, some of the major shareholders in Kibo entered into discussions with the Company regarding the projects that Kibo have within its portfolio and the costs associated with the further development of these.

These discussions delivered strong support for the Kibo project portfolio and development strategy, culminating in the funding term sheet set out below,” said Louis Coetzee, Chief Executive Officer

of Kibo Energy. Coetzee further said the compelling endorsement from a consortium of highly experienced investors or existing long-term shareholders will enable the continued development of the company’s projects, which are all approaching commercialisation.

“In particular, our project in Mozambique is making vast strides for-ward, where we realistically expect the delivery of two PPAs before the end of 2020 for up to 400 MW; at the start of this year our ex-pectation was for one PPA for 150 MW.

“There is a lot of work still to be done, but our team is focused on delivering on it and we look forward to providing further updates in due course,” Coetzee said.

alkabout Resources has secured exploration tenure over a highly prospective, underexplored gold region in south western Tanzania - the Amani Gold project.

“Walkabout’s strategy has always been to maintain a diversified portfolio and contin-ually look for high value exploration oppor-tunities.

“We believe the Amani gold project with its significant alluvial gold endowment will potentially provide significant value to the Company while not distracting us from the funding and building of the Lindi Jumbo Graphite Project,” said Chairman of Walk-about Resources, Trevor Benson.

According to the company the project displays underexplored prospective high-grade vein and shear hosted orogenic gold terrain and new mapping confirms similar geological setting to gold mineralisation within the Lupa Goldfield 300km to the northwest.

The Amani gold project has been a focus of Walkabout’s exploration team since 2015 when new geological mapping and field-work confirmed the hard rock gold poten-tial of this forgotten alluvial gold area.

In addition, the area has the potential to host high grade orogenic gold mineralisa-tion similar to the Lupa Goldfields where Shanta Gold has numerous deposits.

Walkabout considers this project to be a valuable addition to its diverse mineral ex-ploration portfolio in Africa and the UK.

s part of efforts to combat the spread of COVID-19, Telescopic cranes from Condra will soon be helping a South African chemicals company to produce alcohol in very large volumes for hand sanitizer.

The double-girder cranes with underslung K-Series hoists were or-dered to replace a competitor’s machines used for pump mainte-nance. According to the manufacturer, the machines are of complex design, each featuring a telescopic boom to enable a single crane to service pumps in separate but adjacent bays.

“The boom will extend into position over the adjacent bay, allowing the retrieval of pumps to the principal workshop area for attention by the crane after the boom has retracted.”

The order is for nine identical units, according to Condra, replacing eight machines from rival firms and one of its own hoists, all nine being originally supplied in 1987. Condra won the replacement or-der after the customer considered Condra’s machine to have per-formed the best over the past 33 years.

The new cranes are double-girder underslung machines with under-slung crabs. A foot-mounted hoist on each crane moves between

two girders arranged as an extendable boom beneath the main frame. Condra used KSeries hoists foot-mounted on underslung crabs, lifted up and between the two girders along which they travel to achieve the most compact possible machine dimensions.

Variable-speed drives have been fitted to achieve speeds of up to 4,5 metres per minute on the lift, 20,2 m/min on the cross travel, and 30,7 m/min on the long travel. The variable-speed drives will deliver improved productivity. Only two-speed operation was available on the machines being replaced.

Travel on the telescopic boom will be 4,3 metres per minute.

DEMOLITION CONTRACTORS’ROCK DRILLING



he country’s large mining industry has attracted Dafo Vehicle Fire Protection to partner with ASM Global in endeavours to heighten safety for the local mines operators.

According to the Dafo Vehicle Business Manager - Middle East, North, West, East and Central Africa, Fredrik Rosen the min-ing industry cannot compromise on safety, considering that when a fire breaks out on a heavy vehicle, the results can be devas-tating.

Safety of all employees is fundamental and “nothing can replace a person” that they are, outside of the employment arena. With consideration of Staff being the sustaining life force of any business and the invest-ment all companies make in their people through training and development. These factors cannot be easily dismissed or un-dervalued. Hence the correct engineered robust designed systems should always be the ultimate goal in safety for all. “Expensive repair or replacement of valu-able equipment is the obvious conse-quence. Extensive downtime and business interruption can result in even greater ex-penses as this equipment often takes many months to repair or replace,” Fredrik said.

The same sentiments are shared by ASM Global a family owned business managed by Managing Director, Piers Holl and locat-ed in Kitwe in the Copperbelt, the distribu-tors Dafo Vehicle products.

“The mining industry is one of the harshest environments where large capital is em-ployed. Mindful of this ASM Global has es-tablished its presence in this market sector to bring trusted industry standard quality products with reliable service and manage-ment in support of its clients. Monitoring, managing, and reducing risk are paramount to the profitability of any business,” ex-plained Piers.

Rosen has challenged the local mining in-dustry to choose reliable, robust and effec-tive fire suppression systems for heavy duty vehicles designed to survive challenging working environments and secure safety of operations. “Dafo Vehicle’s systems are designed to mitigate losses due to fire and reduce the impact on investment, reducing downtime and securing business continuity and in-creasing the productivity of the end users.”

Dafo Vehicle Fire Protection use local market to launch into the region

T

Rosen is confident that Dafo Vehicle’s ro-bust system not only protects individual hazards within the vehicle such as leaking fuel, hydraulic fluid, and/or lubrication, built up flammable deposits, but it is also a sys-tem with low life cycle costs. He further highlights that the relative busi-ness partners would have to ensure that the system they are procuring is a robust system fit for purpose in the harsh environ-ment. “Dafo Vehicle Fire Protection has fulfilled the requirements of the Australian Standard AS 5062:2016 - Fire protection for mo-bile and transportable equipment for their SV-K fire suppression system. This has been granted with a Certificate of Approv-al by the Certification Body Global-Mark. The AS 5062-standard is equivalent to the Zambia Bureau of Standards new standard ZS1209/2019. Dafo Vehicle is also in the process of getting an FM approval in accor-dance with FM 5970,” Rosen said. Currently Dafo Vehicle is continuously ex-panding its network of distributors in Africa to support mobile cargo equipment in ports and on heavy-duty mining vehicles and per-sonnel carriers. “We have been active in South Africa for a couple of years but now

we want to strengthen our position all over Africa. At this stage we have distributors in Morocco, Ghana, the Democratic Republic of the Congo, Zambia and South Africa. “Depending on the situation and the market potential there might be a possibility of po-tentially leading the expansion work into the other SADC countries from Zambia,” said Rosen.

According to Rosen, the company offers the most reliable and effective fire suppression systems for heavy-duty mining vehicles de-signed to survive challenging working envi-ronments and secure safety of operations.

“The systems are designed to mitigate losses due to fire and reduce the impact on human life, investment, reducing downtime and securing business continuity and in-creasing the productivity of the end users. Dafo Vehicle’s durable system not only pro-tects individual hazards within the vehicle such as leaking fuel, hydraulic fluid, and/or lubrication, built up flammable deposits, but it is also a system with low life cycle costs,” he said. Rosen indicated that the Dafo Ve-hicle fire suppression system consists of four integrated elements; Detection, Alarm, Suppression and Control which work to-gether in a coordinated, fast and efficient


July - August 2020way to suppress fires. Dafo Vehicle uses a robust linear heat detector cable which is triggered when the temperature reaches 180 °C.

Dafo Vehicle also has a system for electrical cab-inets in heavy-duty mining vehicles as these are well-known sources of fires as it generates enough energy required for the ignition. It also provides the combustible material needed for spreading of the fire. As a response to this Dafo Vehicle has devel-oped our PFK system which combines fire sup-pression abilities with environmental sustainability.

The PFK system agent FK-5-1-12 (Novec) is pres-surized in the agent tank with nitrogen and is a colorless and odorless gas that suppresses fires through cooling and suffocation by removing the heat energy and interrupting the combustion pro-cess. “The clean agent leaves no residue, requires no cleanup is non-conductive and noncorrosive. FK-5-1-12 agent quickly evaporates without harming any valuable assets.”

With over a century in operation, Dafo is one of the first companies in the world which started to de-velop integrated firefighting solutions for vehicles back in 1976. Dafo Vehicle Fire Protection offers retrofitting and servicing of fire suppression sys-tems for all types of heavy-duty mining vehicles both for underground applications and open pit applications. As Dafo Vehicle continues to invest a large portion into R & D and take part actively in research proj-ects, the company has now launched a fire protec-tion system for electric and hybrid vehicles that is activated before a fire in a battery occurs. “The fire protection solution has been developed for buses but is also available for other heavy elec-tric vehicles as we now see are entering the mining environment.”

Some of Dafo Vehicle’s accolades include being chosen as an Innovation Label Winner at Busworld Europe 2019 and the Innovation Label by Busworld Awards rewarded INNOVATIVE products and ser-vices. The Innovation label was rewarded to Dafo Vehicle’s research project Li-IonFire™ which is one of the most advanced research projects fund-ed under the EU Framework Program for Research and Innovation – H2020 – under the SME Funding Scheme.

Li-IonFire™ investigated how to deal with fire hazards of Li-ion batteries in vehicles in order to provide solutions for reducing the risks and conse-quences of a thermal incident in or in connection with Li-ion batteries in heavy commercial HEVs and EVs. In addition, Dafo Vehicle has introduced the DafoCLOUD which is a cloud-based risk man-agement system to provide a full overview of the lifecycle of Fire Detection and Suppression Sys-tem (FDSS). “The DafoCLOUD provides access to the full history and genealogy of sub-systems of the FDSS and the complete information is seamlessly accessible and updatable by relevant stakeholders. The Dafo-CLOUD is the basis for reducing and controlling the total cost of ownership with keeping maximized safety in focus,” Rosen said.

xpensive metalworking fluids are no longer needed to cool and lubricate work-pieces and cutting tools in the machine tool industry. Instead, there is now a proven green and clean method, EcoCooling that uses only ionized and cooled air and has none of the environmental hazards and costs related to oil-based fluids.

EcoCooling is the result of long-term, inter-disciplinary R&D from the same team that developed the technology behind Amazon’s ground-breaking family of front-lit Kindle de-vices. Now the group of scientists, engineers and experienced businesspeople from various disciplines has developed a dry, clean and environmentally friendly method to lubricate metal work-pieces with ionized and cooled air without using any emulsions. “Workshops have wanted to get rid of fluids and many have tried to find a solution to the problem, but with poor results”, said Leo Hatjasalo, co-founder and CEO of EcoCooling. “Now we have the an-swer to this demand, since EcoCooling can be used even with the hardest known metals like chrome, titanium and tungsten carbides.” The global market value for metalworking fluids is estimated at approximately $ 12bn this year. It

On the verge of a green, clean era in the metal tool industry

E is growing steadily, with estimates for the glob-al market value for machine tools expected to grow from $ 120bn to $ 150bn in five years’ time. The growth is driven, for example by the accelerating need for components in the aero-space, automotive and transport sectors.

“EcoCooling is based on the fact that ionized air penetrates the cutting zone and forms a dry lubricant that decreases cutting friction and generated heat, at the same time speeding up the oxide layer formation”, Hatjasalo said.

“The process is patented on all continents, and at the moment we are validating it to include all types of machine tools.” Hatjasalo empha-sizes that EcoCooling is not only a way to cut down the costs of emulsions, but also a way to improve productivity through higher cutting speed, reduced wear of cutting tools and mini-mized maintenance costs.

“Since the metal chips are not contaminated by any fluids, they can also be fully recycled with-out cleaning”, he says. “Another big advantage is that it eliminates toxic fluid waste and fumes, in addition to minimizing CO2 emissions, since no oil is used.” The technology makes it pos-

sible to build smaller and cheaper metalwork-ing machines, since the EcoCooling unit is very compact in size.

“The unit does not need any service and it has proved to prolong the lifetime of the cut-ting tools significantly”, Hatjasalo says. “The system can also be easily retrofitted to older machine tools.” During the past few years, EcoCooling has been successfully trialled in numerous commercial tests in demanding sur-roundings internationally. Now that the pro-cess has proved to give excellent results, big savings and substantially less environmental impact, the aim is to create a versatile Eco-Cooling product family that includes all ma-chine tools in addition to just turning machines. “We are also planning to integrate the system to suit different CNC machine tools and to cre-ate optimal solutions for all machine tools and workshop environments”, Hatjasalo said.

“However, for that purpose we need more funding than we can raise on our own. There-fore, the next step is to find an industrial part-ner to help us to commercialize EcoCooling globally and to develop the ways the technolo-gy can be used.”


July - August 2020Trends & Technologies

actory automation continues to develop year on year and pumps are increasingly required to supply real time operating data to control networks so that their performance can be monitored and adjusted to meet constantly changing production requirements. Hard wiring a sen-sor into a pump’s rotating drive shaft usually requires the use of a delicate slip ring, but an alternative solution is to use a non-contact radio frequency detector, as Mark Ingham of Sensor Technology Ltd in the UK explains. As industry strives to become more and more productive, technologies that support smart factories, Industry 4.0 and the Indus-trial Internet of Things, are being used with increasing frequency on the shop floor. The potential of these and other developments to improve manufacturing quality and efficiency over time is almost limitless. However, such

Torquing about advanced pump controllerF

advances are not without their difficulties; one such being the need to connect ma-chines and equipment such as pumps, mix-ers and conveyors to the control computers. Wiring up one machine is not a great task, but a highly automated factory will have liter-ally hundreds or even thousands of them, so the task becomes very considerable.

Thus even a moderately sized factory has to employ a significant number of electricians and engineers who spend their days wiring and rewiring equipment. It follows that, if the

amount of time spent on wiring and instal-lation could be reduced, the factory could reduce its operating costs significantly.

One of the most time consuming tasks is fit-ting torque sensors to rotating equipment, as this requires the use of fiddly and fragile slip rings. However, torque is a key performance indicator. For instance, a gradual increase in a pump’s torque may suggest increasing flow to compensate for growing leakage; a sudden increase may indicate a block-age downstream of the pump, while a sud-

July - August 2020den reduction may be due to an upstream blockage. So in automated plant it is well worth measuring torque, but can fitting a suitable sensor be made quicker, easier and therefore more cost effective? The answer to this question is ‘yes’. TorqSense is a wireless sensor that replaces the need for physical wiring and slip rings with radio wave communications. Fitting a TorqSense typically takes about one-fifth the time required for a conventional hard wired transducer, but how do they work?

A shaft under rotary load will twist very slightly along its length, in proportion to the magnitude of the load. TorqSense measures this twist in real time and its electronics con-verts the reading into a torque value.TorqSense transducers use two Surface Acoustic Wave (SAW) devices, which are attached to the surface of the shaft. When torque is applied to the shaft the SAWs react to the applied strain and change their output. The SAW devices are interrogated wirelessly using an RF (radio frequency) couple, which passes the SAW data to and from the elec-tronics inside the body of the transducer.

Sensor Technology’s Mark Ingham explains: “All you have to do is set up a TorqSense is glue the SAWs to the shaft, fire radio waves at them and monitor the waves that are re-flected back. The SAWs are distorted in proportion to the twist in the shaft, which in turn is proportional to the level of torque. The

frequency of the reflect waves is changed in proportion to the amount of distortion and electronics within the TorqSense analyses the returning wave and feed out torque val-ues to a computer screen.

As the TorqSense method does not require contact with the rotating shaft it offers com-plete freedom from the slip rings, brushes or other solutions found in traditional torque measurement systems. TorqSense devices also have a high immunity to magnetic forc-es, allowing their use in, for example, motors where other technologies are very suscepti-ble to electronic interference.” Conceptually Bluetooth is very similar to TorqSense. It is a wireless technology that enables data ex-change over short distances and, like Torq-Sense, its transmits using radio waves. It is commonly found in hands-free phones and other mobile devices, so is used by many people on a daily basis. In the engineering and industrial worlds, it is often favored as a wireless alternative to RS232 data cables and can connect several devices simultane-ously. Sensor Technology’s new Bluetooth module creates totally wireless solutions for torque measurement. In use the module simply plugs into the TorqSense’s existing 15 way ‘D’ digital lead connector. As well as collecting torque signals, the modules can provide power to the TorqSense transmit-ter/receiver and provides a USB output for connection to a PC. Bluetooth/TorqSense will be welcome in cable-dense environ-

ments such as automated factories and will enable torque monitoring via any Bluetooth enabled device. Sensor Technology has also launched an Android app that allows torque parameters to be monitored via a standard mobile phone or tablet, without the need for a PC.SAW-based torque sensors have been used around the world and in many fields, from test rigs to wind turbines and genera-tors based on tidal or river flows. They are used extensively in the high tech world of the development of engines and gearboxes for Formula 1 and other hyper performance cars. Torque feedback systems have also been used by security firms to determine the direction their movable CCTV cameras are facing so that they can efficiently watch premises under their protection, in industrial mixing, long duration scientific experiments, to model aircraft thrust lift and control sys-tems, etc.

They can be used with virtually all pump-based systems, from microdosing of active ingredients in pharmaceutical production, to cake filling injection in high volume bak-eries, to lubricant and coolant circulation in manufacturing machinery, to flow control in industrial washing machines and paint spray robots; they can prove invaluable when cou-pled with the giant pumps used for fresh wa-ter distribution, foul water handling and flood management systems. In fact it is fair to say that their potential uses with pumps are al-most endless.

synergies from Sustainable economic activities” and “creating transparency and good governance in re-source extraction”. In implementing the strategy the, the German Government, through the Federal Minis-try of Economic Affairs and Energy (BMWi) promotes socially responsible mining by supporting various projects globally. Business Integrity, Planning for positive post mining legacies, social responsibility and environment responsibility are critical aspects of responsible mining. Corporate Social Responsibility (CSR) and Mine Health and Safety (MH&S) are integral to social responsibility. As such the CCMR (supported by the BMWi) embarked on a Mine Health and Safety project in 2018 and the project is planned to run until end of 2020.

The first phase of the project (2018) was a best prac-tice report (publication) on mine health and safety. The purpose of the publication was to report on the best practices in the realm of MH&S and create awareness of through a series of workshops with MH&S profes-sional’s in the SADC region. The CCMR identified that these practices in CSR and MH&S were being imple-mented in South Africa’s (SA) mining industry and as such the publication focused on SA. The publication was endorsed by the prestigious Wits Mining Institute and received media coverage from the mining Week-ly, Engineering News, Mines Online and other mining publications.

Phase two of the project (2019) involved the hosting Mine Health and Safety Workshops in the SADC re-gion. These were held in Sowa Town and Gaborone (Botswana), Kathu and Johannesburg (South Afri-ca), Luanda (Angola) and Maseru (Lesotho). Various experts from the Minerals Council and Independent Consulting Firms and Service Providers gave talks on various issues ranging from Fatigue Management, Traffic Management in Open Pit Mines, Occupation-

al Hygiene and Risk Management. The workshops proved to be very successful with Mr Charles Siwawa (CEO, Botswana Chamber of Mines) saying after the event that “the vibes all week point towards a well-run workshop with good concepts that the guys are able to practically implement” and Mr Ntsane Makhetha (SHEC Manager, Liqhobong Mining Development Company-Lesotho) saying that “the seminar made an invaluable impact and was recognised widely”.

Phase 3 of the project was planned involve the host-ing of workshops in Angola, Namibia, Democratic Re-public of Congo, Mozambique, Zambia and Malawi in 2020. However, due to the Covid-19 global pandemic the workshops will be replaced by a Mine Health and Safety Webinar where participants from the region can attend. Furthermore, in partnership with Minerals Council of South Africa and Afriforte (North West Uni-versity) , the CCMR will run a Mental Health Promotion and Connect with Staff project on Afriforte’ COVID-19 Debriefing Platform. The project aims to assess the state of the mental well-being of mineworkers in light of the Covid-19 pandemic. The objectives of the as-sessment is to assist mines deal with mental health issues in line with ISSA Mining’s Vision Zero for mine health and safety initiative. The project will involve the physical screening of mine employees at 10 South Af-rican mines as well as the remote screening of mine employees at some mines in the SADC region.
