Technical challenges balloon Karowe underground project costs over P9 billion
Business

The highly anticipated Karowe Underground Project will now be completed in H1 2028, two years later than the initially planned timeline of H1 2026.
In an update to the market this week Lucara Diamond Corp said grouting programs took longer than anticipated due to a combination of high‐water volumes in the sandstone lithologies between 870 and 752 metres above sea level in depth (144 metres to 262 metres below the shaft collar) combined with technical challenges associated with the transition to main sinking.
The project schedule has a 28% increase in the duration of construction, extending the anticipated commencement of production from the underground from H2 2026 to H1 2028.
As a result, the revised forecast of costs at completion is $683 million (approximately P9 billion), a 25% increase to the May 2022 estimated capital cost of $547 million (about P7 billion).
While the existence of water‐bearing sandstones layers was anticipated, grouting within the regional Ntane and Mosolotane sandstone aquifers has required significantly more volumes of chemical grout.
In addition, some remedial grouting in previously dry portions of the sandstone horizons has been required in the ventilation shaft. These factors account for most of the incurred delays.
Planned grouting events to the base of the Mosolotane sandstone/mudstone transition are expected to be completed early in Q4 2023. After completion of the current sandstone layer being grouted, one further grouting event is planned in the ventilation shaft (currently 213 metres below collar).
Two additional grouting events are planned within the production shaft (currently 185 metres below collar). Thereafter, further grouting is not anticipated to be required until sinking reaches the granite basement lithologies in late 2024. Grouting in the granite lithologies is expected to be localized, rather than formational in nature.
Total depth of the final shaft bottoms are 765 metres and 731 metres below surface for the production and ventilation shafts, respectively. The project has been operating with an excellent safety record including 1,244 days and > 3.3 million hours Lost Time Injury free and a Total Recordable Injury Frequency rate of 0.59.
The increase of $136 million in estimated capital to reach project completion is predominantly related to increased schedule duration and related labour costs (approximately 56% of total), and grouting costs (approximately 20% of total capital increase) which have been funded through contingency. The remaining cost increases are related to Owner’s costs, procurement, and indirect project costs.
As at June 30, 2023, capital expenditures of $264.5 million had been incurred and capital commitments of $369.7 million had been made. The remaining forecast to complete construction of the project as of June 30, 2023 is $419 million including unallocated contingency of $49.3 million (12%).
Karowe Open Pit and Processing units continue to perform to budget expectations and the planned ore feed for the remainder of 2023 has transitioned to a South Lobe dominant mill feed. As a result, the recovery of large high value +100 carats diamonds sourced from the M/PK(S) and EM/PK(S) units is in line with resource expectations and previous half‐year recoveries.
Lucara underscored that the project remains technically and economically feasible, however, the impact of actual and modelled delays changes the revenue profile due to the use of lower‐grade, stockpiled ore for mill feed rather than high‐grade ore from the underground as previously planned.
Sufficient surface stockpiles of South, Centre and North Lobe kimberlite ore are available to maintain current, un‐interrupted mill feed to the plant for the duration of the anticipated delay.
The long‐term outlook for diamond prices, combined with the potential for exceptional stone recoveries and the continued strong performance of the open pit could mitigate the modelled impact on project cash flows due to the schedule slippage.
Eira Thomas, CEO of Lucara Diamond Corp said the has made tremendous progress on the Karowe underground expansion project, despite many challenges over the last year as we transitioned into the main sink phase of the underground development.
“Schedule delays due to longer than anticipated grouting activity have impacted the project timeline, however the grouting methodology selected has proven to be effective in controlling water inflows. As we transition out of the sandstones in early Q4 2023, we look forward to meeting planned sinking rates,” Thomas said.
“Despite these challenges, the project continues to deliver strong economics paying back capital in under three years and adding approximately $4 billion in revenues from an extended mine life out to at least 2040, using conservative diamond price assumptions.
“The project also comes at a time when the long‐term outlook for the diamond market is stronger than it has been for many years representing an exciting growth opportunity for our shareholders and stakeholders in Botswana.”
Lucara’s major shareholder remains supportive of the Karowe asset and the long‐term potential of the Karowe UGP. Adam Lundin commented: “The Karowe underground mine expansion provides access to the highest value portion of the orebody responsible for delivering numerous record‐breaking diamonds in respect of size and value, including three diamonds in excess of 1,000 carats. The project remains highly economic, despite the delays incurred, and as Lucara’s largest shareholder, we remain fully supportive of the company.”

With just four weeks to go, the Gambling Authority of Botswana has revealed that it is expecting a record attendance at the much anticipated International Association of Gambling Regulators (IAGR) Conference, which will be held in Botswana from 16 – 19 October 2023.
According to a communique from the IAGR, the Gambling Authority will most probably break the record in the number of accredited countries that will attend the conference in Botswana.
“We are on track to match and potentially exceed the incredible delegate turnout we saw in Melbourne last year,” read a statement from IAGR’s.
In its global reach alert, IAGR revealed a glimpse of jurisdictions that will be represented at the conference, among them Australia, Canada, Denmark, Japan, Jersey, Mauritius, United Kingdom, United States and Netherlands. African countries that have so far confirmed attendance include Zimbabwe, South Africa, Nigeria, Tanzania, Kenya and Burundi.
Commenting on the expected bumper attendance, IAGR said the amazing diversity elevates the conference to a whole new level, which will enrich discussions with a tapestry of regulatory perspectives and insights.
Botswana won the bid to host this year’s conference last year in Melbourne, Australia. The IAGR consists of representatives from gaming and gambling regulatory organizations from around the world; with a common mission to advance the effectiveness and efficiency of gaming regulation.
According to Gambling Authority Chief Executive Officer (CEO) Peter Kesitilwe, the Authority is a member of the IAGR by dictates of the Gambling Act; which compels it to align with international organizations whose objectives are to regulate gambling, and build collaboration among regulators.
“The IAGR conference is held annually and hosted by different member jurisdictions. It provides opportunities for gambling and gaming regulators from around the world to engage, learn and network with industry peers through events, workshops, research, information sharing, and the development of best practices,” explained Kesitilwe.
Funding requirements for the conference are shared between IAGR, the host country and conference participants. The government of Botswana has reaffirmed its commitment to supporting the Gambling Authority to host IAGR; as it is in line with its objectives of promoting the country as a Meetings, Incentives, Conferences, and Exhibitions (MICE) tourism destination.
According to Kesitilwe, the conference is coordinated by a Technical Committee of IAGR; together with a Local Organizing Committee (LOC) that comprises of representatives from the Ministries of Trade, Tourism, Foreign Affairs, Botswana Police Service and other stakeholders.
“We promise to deliver this hugely important event and showcase the best that Botswana has to offer. In addition to the exchange of ideas and culture capital, the Organizing Committee will also ensure maximum benefits for the tourism, hotel and hospitality industry, entertainment, transport, telecommunications, vendors, hawkers of cultural artifacts,” said Kesitilwe.
As part of preparations to host IAGR2023, the Gambling Authority recently went on a benchmarking mission to Great Britain.
“What we learnt there can assist the Gambling Authority as we enter a new era of growth and expansion. The meeting also provided a timely opportunity to catch up on preparations for IAGR2023. We are ready to host the conference and we look forward to meeting other regulators from across the world to share best practice, discuss common challenges and tackle illegal gambling,” concluded Kesitilwe.

Choppies Enterprises Limited, a supermarket chain led by Botswana businessman Ramachandran Ottapathu, reported an increase in profit after tax which is up 3.4%, hence improving from P145 million realized in 2022, to P150 million in 2023.
The results demonstrate sustained increases in consumer demand, improved operational flexibility, efficiency, cost-effectiveness and despite stiff competition, the Group managed reduce its debt levels by paying off P263 million debt from the previous fiscal year.
The chain supermarket realized growth in Group retail sales which went up 6.5% to BWP6 433 million compared to P6 042 recorded in 2022. The growth is attributed to a broad presence across Botswana and a growing footprint in three other African countries, being South Africa, Zambia and Zimbabwe, according to a recently financial results statement.
In Pula terms, gross profit grew by 4.0% to BWP 1 359 million (2022: BWP 1 307 million) despite the challenging economic environment. Botswana and Namibia marginally grew gross profit rates while rates in Zambia and Zimbabwe declined.
During the period under review, the group’s Group net cash generated from operating activities rose by 4.5% to P484 million, this is a significant improvement when compared to P463 million recorded in 2022. This segment was boosted by strong showing from Botswana and Namibia, which performed exceptionally despite the challenging trading conditions. Furthermore, it was driven by sixteen new stores coupled with price growth of 6.8%.
As a result of the robust financial performance, the group’s total assets increased from P1 886 million to P2 177 million, while retained losses decreased from P811 million to P664 million.
Meanwhile, the Group faced a demanding economic environment characterised by stubbornly high inflation, higher interest rates and unemployment, all of which continue to constrain consumer spending and the consumer’s ability to digest higher prices. Sales volumes were lower in many categories, exacerbated by competitor discounting, with cost pressures only partly recovered through price increases.
According to the audited results, the gross profit margin accordingly reduced to 21.1% from last year’s 21.6% due to higher supply chain costs, including fuel and managing prices in response to higher cost inflation and competitor discounting.
Furthermore, while expenses increased 5.1% excluding the depreciation restatement, expenses grew 9.8% partly due to new stores and inflation. Foreign exchange losses on lease liabilities of P31 million (against a gain of P28 million last year) were partly offset by foreign exchange gains on Zimbabwean legacy debt receipts of P18 million (2022: BWP15 million).
Operating profit (EBIT) reduced by 1.8% from BWP 279 million to BWP 274 million whilst Adjusted EBIT, which excludes foreign exchange gains and losses on lease liabilities, movements in credit loss allowances, Zimbabwean legacy debt receipts and the reassessment of depreciation, reduced by 7.5% as costs grew faster than gross profit.
CASH MANAGEMENT
According to the Choppies Enterprises financial statement commentary, the Group continues to manage its cash resources and liquidity prudently with a reduction of P132 million in debt with P87 million paid out of internally generated funds and the balance of P45 million paid out of the proceeds of the rights issue.
In addition, capital expenditure increased to P185 million when compared to 2022 fiscal year which had recorded P122 million. This was a result of the Group strategy to invest in new stores and maintaining the distribution fleet.
Choppies Enterprises raised BWP50 million from leases to fund the fleet, an improvement because in 2022 only P36 million was raised.
Despite the growth in sales, inflation and new stores, Choppies Enterprises inventory reduced by P20 million helped by more stable global supply and the benefits of implementing an inventory optimisation system.
Finally, commentary from the Choppies Enterprises Group observes that as the economies in which the Group operates recover and the new stores reach full potential, an improvement in margins is expected. “With a value proposition that resonates with customers and with the cost of everyday items still stubbornly high in too many categories, more customers are choosing Choppies for the value and assortment we are known for. While we have strong and resilient brands, affordability is a growing constraint for consumers, limiting their ability to digest higher prices,” reads a commentary on the Group’s Financial statement.
Choppies Enterprises Limited (“the Company”) is a Botswana-based investment holding company operating in the retail sector in Southern Africa. Dual-listed on the Botswana Stock Exchange (“BSE”) and Johannesburg Stock Exchange (“JSE”), its are food and general merchandise retailing as well as financial service transactions supported by centralised distribution channels through distribution and logistical support centres. Each week, approximately 2.0 million customers visit 177 stores under five formats in four countries. With annual revenue of more than BWP6 billion, Choppies employs 10 000 people and is the largest grocery retailer in Southern Africa, outside of South Africa.
EVENTS AFTER REPORTING DATE
On 19 July 2023, Choppies acquired 76% (seventy-six percent) of the Kamoso Group for BWP2.00 (two Pula) and took cession of shareholders’ loans to the value of BWP22 million. The Botswana Development Corporation (BDC) will retain its 24% stake.
This acquisition will take Choppies to become a P8 billion business in revenue with 11 000 employees and 274 retail stores.
SNEAK VIEW: COUNTRY PERFORMANCES
According to the financial results, Botswana experienced sales growth to BWP4 459 million an improvement from P4 209 million recorded in 2022. This was supported by volume growth from new stores and double-digit price inflation. Sales from Botswana increased by 5.9% and like-for-like sales growth was 2.2%, as the business continued to show strong resilience in an increasingly challenging economic environment. The Botswana economy continues to experience elevated inflation, high unemployment, and low economic growth.
EBITDA grew 5.8% and adjusted EBITDA was flat on last year. The performance for the second half was much stronger than in the first half as our strategies, leadership and inventory optimisation system have started to come to fruition.
As for the Rest of Africa being Namibia, Zambia and Zimbabwe sales increased by 7.7% to P 1 974 million, yet another improvement from 2022, which had realized P1 833 million sales. The increase was driven by the addition of nine new stores, inflationary increases in Zimbabwe and Zambia and volume growth in Namibia and Zambia. “However, this was offset by a very weak Zimbabwean Dollar resulting in Zimbabwe’s Pula sales declining by 48.3%.”
Meanwhile Namibia has successfully turned around with sales growth of 60.0% and like-for-like sales growth of 14.4%. Five new stores were opened during the year. EBITDA grew 140% with EBIT loss reducing from BWP9 million to BWP2 million. Adjusted EBIT, excluding the depreciation reassessment, reduced from BWP9 million to BWP6 million.
Connectedly, Zambia continues to grow with sales up 44.7% and like-for-like sales growth of 33.3%. Three new stores were opened during the year. While EBITDA declined by 26.4% due to the foreign exchange loss on the lease liability, adjusted EBITDA grew 27.1%. Adjusted EBIT declined marginally at 2.6%. Choppies Enterprises Directors are confident that Zambia will generate taxable profits in the foreseeable future.
Lastly in Zimbabwe, the Zimbabwean Dollar (ZWL) has significantly weakened especially in the last two months of the financial year. As a result of the above mentioned factors, Pula sales declined by 48.3%. EBIT and EBITDA declined by 151.6% and 125.5% respectively as cost inflation reduced margins. Adjusted EBIT and adjusted EBITDA declined 133.3% and 108.1% respectively.
