De Beers research to make carbon-neutral mining a reality
Business
De Beers Group today announced it is leading a ground-breaking research project that aims to deliver carbon-neutral mining at some of the company’s operations in as few as five years.
The company’s scientists are working in close collaboration with a team of internationally-renowned scientists to investigate the potential to store large volumes of carbon at its diamond mines through the mineralisation of kimberlite ‘tailings’, the material that remains after diamonds have been removed from the ore.
De Beers Group will investigate the storage potential across its diamond mines globally. It is the first time such extensive research has been undertaken to assess the carbonation potential of kimberlite, a rare type of rock that has been found to offer ideal properties for storing carbon through mineral carbonation technologies.
The project aims to accelerate what is already a naturally occurring and safe process of extracting carbon from the atmosphere and storing it at a speed that could offset man-made carbon emissions. Scientists estimate that the carbon storage potential of kimberlite tailings produced by a diamond mine every year could offset up to 10 times the emissions of a typical mine.
De Beers Group’s Project Lead for the initiative, Dr Evelyn Mervine, said: “This project offers huge potential to completely offset the carbon emissions of De Beers’ diamond mining operations. “Mineral carbonation technologies are not new, but what is new is the application of these technologies to kimberlite ore, which is found in abundance in the tailings at diamond sites, and which offers ideal properties for the storage of very large volumes of carbon. “As part of the project, we are looking at how these existing technologies can be modified to develop specific solutions suitable for storing carbon in kimberlite tailings.
“The research is in its early stages and it may take some time before it is economically or practically achievable to tap into this full storage potential. However, even just tapping into a small amount could greatly reduce the net emissions at many of our mine sites in the near future, and possibly lead to carbon-neutral mining at some sites within the next five to ten years. “As technology improves over time, more and more carbon could feasibly be stored in kimberlite tailings, meaning we could ultimately offset more emissions than we are producing.”
Mineral carbonation is a natural or artificial process whereby rocks at the Earth’s surface react with carbon dioxide sourced from the atmosphere and lock it away in safe, non-toxic, solid carbonate materials – taking that form in kimberlite rock in this instance. The work being undertaken by the project team could have significant applications for the broader mining industry, as the ideal carbon storage characteristics of kimberlite rock are also found in rocks mined for other commodities, such as nickel and platinum.
De Beers Group CEO, Bruce Cleaver, said: “By replicating this technology at other mining operations around the world, this project could play a major role in changing the way not only the diamond industry, but also the broader mining industry, addresses the challenge of reducing its carbon footprint.
“By investing in ground-breaking projects such as this, aligned with the FutureSmart Mining™ innovation programme of our parent company, Anglo American, we have the real potential to leave a positive, long-lasting legacy for the global mining industry.” De Beers started the project in 2016. A key part of its early work was centred on supporting academic-focused mineral carbonation studies of old (pre-1912) and recent (post-2008) kimberlite tailings samples from Voorspoed Mine in South Africa, which provide a great ‘natural laboratory’ for understanding carbonation reactions in kimberlite.
Mineral carbonation potential assessment studies are currently underway for Venetia Mine in South Africa and Gahcho Kué Mine in Canada. Further research and detailed studies will continue in 2017 and 2018 to assess the carbonation potential at these and other De Beers Group mines.

Grit Services Limited, a member of the pan African real estate group, London Stock Exchange listed Grit Real Estate Income Group is divesting from Letlole La Rona Limited (LLR), a local real estate company established by government investment arm Botswana Development Corporation over a decade ago.
The Board of Directors of Letlole La Rona Limited this week announced in a statement to Unitholders that Grit Services Limited (‘Grit’) has informed them of its intention to exit its investment in the company.
Grit has been a material shareholder in LLR since 2019. On 07 March 2023, Grit sold 6 421 000 linked units, representing 2.29% of the Company’s total securities in issue, at a market value of BWP 22 537 710.
This trade follows previous sales of 6.79% in December 2022, as communicated to Unitholders on 10 January 2023, as well as a further sale of 4.78% (representing 13 347 068 linked units) on 24 February 2023 to various shareholders.
In aggregate, Grit has sold 13.9% shareholding in the Letlole La Rona between December 2022 and March 2023, resulting in current shareholding of 11.25% in the Company.
Letlole La Rona said in the statement that the exit process will take place in an orderly manner so as to maintain stability of the Company’s share price.
The statement explained that Grit’s sale of its entire shareholding in LLR is in line with its decision to exit investments where it does not have majority control, or where it has significant exposure to currencies other than US dollar, Euro or hard-currency-pegged revenue streams.
“Grit has announced similar decisions pertaining to certain of its hospitality assets in Mauritius recently. The Company would like to advise Unitholders that it remains focused on long-term value delivery to all stakeholders” LLR said
In July last year as part of their Go-to-Africa strategy Letlole La Rona acquired an initial 30% equity stake in Orbit Africa Logistics, with an option to increase this investment to 50%. OAL is a special purpose vehicle incorporated in Mauritius, owning an industrial asset in a prime industrial node in Nairobi, Kenya.
The co-investment was done alongside a wholly owned subsidiary of London listed Grit. The Orbit facility is situated on a prime industrial site on Mombasa Road, the principal route south of Nairobi center, serving the main industrial node, the port of Mombasa and the industrial town of Athi River and is strategically located 11 kilometers south of the international airport and 9.6 kilometers from the Inland Container Depot.
Grit shareholding in Letlole La Rona was seen as strategic for LLR, for the company to leverage on Grit’s already existing continental presence and expand its wings beyond Botswana borders as already delivered by Kenya transaction.
Media reports have however suggested that LLR and Grit have since late last year had fundamental disagreements on how to go about the Go-to-Africa strategy amongst other things, fuelled by alleged Botswana government interference on the affairs of LLR.
Government through LLR founding shareholder – Botswana Development Corporation has a controlling stake of around 40 percent in the company. Government is the sole shareholder of Botswana Development Corporation.
Letlole La Rona recently released their financial results for the six months ended December 2022, revenue increased by 4% to P50.2 million from P48.4 million in the prior comparative six months, whilst operating profit was up 8% to P36.5 million. Profit before tax of P49.7 million was reported, an increase of 8% on the prior comparative six months.
“We are encouraged by the strong results, notwithstanding a challenging economic environment. Our performance was mainly underpinned by annual lease escalations, our quality tenant base and below average market vacancy levels, especially in our warehouse portfolio,” Kamogelo Mowaneng, Letlole La Rona Chief Executive Officer commented.
LLR reported a weighted average lease expiry period of 3.3 years and escalation rates averaging 6.8% per annum for the period ended 31 December 2022.Its investment portfolio value increased by 14% year-on-year to close the period at P1.4 billion, mainly driven by the acquisition of a 30% stake in OAL in July 2022.
The Company also recorded a significant increase in other income, predominantly due to foreign exchange gains on the OAL shareholder loan. “We continue to explore pipeline opportunities locally, and regionally in line with our Go-to-Africa strategy and our interest remains on value-accretive investments,” Mowaneng said.
An interim distribution of 9.11 thebe per linked unit was declared on the 6th of February 2023 for the half-year period to 31 December 2022, comprising of a dividend of 0.05 thebe and debenture interest of 9.06 thebe per linked unit which will be paid to linked unit holders registered in the books of the Company at the close of business on 24 February 2023.

Internationally-acclaimed diamond manufacturing company StarGems Group has established the Stargems Diamond Training Center which will be providing specialized training in diamond manufacturing and evaluation.
The Stargems Diamond Training Institute is located at the Stargems Group Botswana Unit in Gaborone.
“In accordance with the National Human Resource Development Strategy (NHRDS) which holds the principle that through education and skills development as well as the strategic alignment between national ambitions and individual capabilities, Botswana will become a prosperous, productive and innovative nation due to the quality and efficacy of its citizenry. The Training Centre will provide a range of modules in theory and in practice; from rough diamond evaluation to diamond grading and polishing for Batswana, at no cost for eight weeks. The internationally- recognized certificate offered in partnership with Harry Oppenheimer Diamond Training School presents invaluable opportunities for Batswana to access in the diamond industry locally and internationally. The initiative is an extension of our Corporate Social Investment to the community in which we operate,” said Vishal Shah, Stargems Group Managing Director, during the launch of the Stargems Diamond Training Center.
In order to participate in this rare opportunity, interested candidates are invited to submit a police clearance certificate and a BGCSE certificate only to the Stargems offices. Students who excel in these programs will have the chance to be onboarded by the Stargems Group. This serves as motivation for them to go through this training with a high level of seriousness.
“Community empowerment is one of our CSR principles. We believe that businesses can only thrive when their communities are well taken of. We are hoping that our presence will be impactful to various communities and economies. In the six countries that we are operating in, we have contributed through dedicating 10% of our revenues during COVID-19 to facilitate education, donating to hospitals and also to NGOs committed to supporting women and children living with HIV. One key issue that we are targeting in Botswana is the rate of unemployment amongst the youth. We are looking forward to working closely with the government and other relevant authorities to curb unemployment,” said Shah.
Currently, Stargems Group has employed 117 Batswana and they are looking forward to growing the numbers to 500 as the company grows. Majority of the employees will be graduates from the Stargems Diamond Training Center. This initiation has been received with open arms by the general public and stakeholders. During the launch, the Minister of Minerals and Energy, Honorable Lefoko Moagi, stated that the ministry fully endorses Stargems Diamond Training and will work closely with the Group to support and grow the initiative.
“As a ministry, we see this as an game changer that is aligned with one of the United Nations’ Six Priority Sustainable Development Goals, which is to Advance Opportunity and Impact for Diversity, Equity, and Inclusion (DEI). What Stargems Group is launching today will have a huge impact on the creation of employment in Botswana. An economy’s productivity rises as the number of educated workers increases as its skilled workmanship increases. It is not a secret that low skills perpetuate poverty and widen the inequality gap, therefore the development of skills has the potential to contribute significantly to structural transformation and economic growth by enhancing employability and helping the country become more competitive. We are grateful to see the emergence of industry players such as Stargems Group who have strived to create such opportunities that mitigate the negative effects of COVID-19 on the economy,” said the Minister of Minerals and Energy.

The latest figures released by Statistics Botswana this week shows that food import bill for Botswana slightly declined from around P1.1 billion in November 2022 to around P981 million in December during the same year.
