A-Cap Energy Limited, the Australian listed energy development company has returned major uranium intersections in drilling at its flagship Letlhakane Project in Botswana, host to one of the world’s top 10 undeveloped uranium resources, the company said in a statement on Tuesday.
The 1,406m diamond drill core program over 24 PQ triple tube holes program collected approximately 2 tonne of mineralised material for beneficiation, leaching, and metallurgical test work already underway.
A-Cap Managing Director Dr Andrew Tunks said the diamond drilling intercepts confirmed Letlhakane’ phenomenal potential.
“It is a massive low-grade deposit with thick mineable lenses of mineralisation that are very continuous. The next steps are to get this sample material to Australia and commence a raft of beneficiation testwork to determine the potential to upgrade the ore and reduce the acid consuming minerals. These two factors will have an enormous impact on an updated feasibility study which we will commence once the data is received,” Dr Tunks said.
Samples from Gorgon South, Kraken, and Serule West were selected as representative of likely Run Of Mine (ROM) ore using criteria which includes the most dominant ore types in the Resource Model, dominantly primary ore which is spatially representative of optimised pits from 2015 Feasibility Study. The samples include material which was scheduled early in the mining plan from the same 2015 Study.
There is over 2,500 kg of mineralised material grading 277 ppm U3O8 (with ~1,200 kg grading 470 ppm U3O8). The application for an Export Permit to ship the sample to Australia is currently being prepared.
To increase Letlhakane’s profitability, A-Cap has engaged technical partners with world-leading expertise in uranium ore sorting and processing that specialise in increasing the ore feed grade to the mill as well as removing acid consuming gangue utilising advances in sorting technology.
In a statement on Tuesday A-Cap said the ore material collected in recent drilling will be sent to mineral processing leaders Nagrom in Perth for sample preparation before being sent to magnetic separation company Steinert Australia for sorting/beneficiation testwork utilising radiometric, XRT, and hyperspectral sensors as well as beneficiation techniques by gravity separation using spiral and dense media separation.
Steinert have been highly successful upgrading uranium ore with sorting programs for other clients in recent years, using radiometric information to pre-classify the ore into product and waste for their program development.
Once they have a “pre-classified” ore and waste fraction, they process these fractions through a sorter with multiple sensors and record all the information from the sensors available on this sorter (colour, laser, induction and XRT).
Subsequently they use proprietary software to detect variations in sensor data between the ore and waste fractions either in: density, colour or any of the other sensors in combination.
There are over 200 parameters recorded and they use multiple sensor combinations to find the best potential sorting algorithm to sort the specific ore.
The Letlhakane Uranium Project is one of the world’s largest (global top 10) undeveloped Uranium Deposits. The Project lies adjacent to Botswana’s main North-South infrastructure corridor that includes a sealed all-weather highway (the A1 Highway), railway line and the national power grid, all of which make significant contributions to keeping the capital cost of future developments low.
Geologically, the Letlhakane uranium mineralisation is hosted within shallow, flat lying sedimentary rocks of the Karoo Super Group. These Permian to Jurassic aged sediments were deposited in a shallow, broad, westerly dipping basin, generated during rifting of the African continent.
The source area for the sediments was the extensively weathered, uranium-bearing, metamorphic rocks of the Archaean Zimbabwe Craton which outcrop in the eastern portion of our license.
The sandstone hosted mineralisation has roll front characteristics, where the uranium was precipitated at redox boundaries. Three ore types have been identified; Primary Ore, Secondary Ore and Oxide Ore. The most abundant is the Primary ore.
A – Cap completed the Bankable Feasibility Study process in 2014 and was initially expecting first production 2015; however regulatory delays pushed the production timelines to 2018. The company then revised their construction targets to the last quarter of 2018, after government awarded them a 22 year mining license in September 2016.
On the 10th of July 2017, A-Cap filed a regulatory requirement with the then Ministry of Minerals Energy and Water Resources, Department of Mines, advising that the preconstruction and construction period of the Letlhakane Uranium project would be delayed by two years. Project take off was later deferred again following uncertainty with global uranium commodity prices.
The future of Botswana’s largest copper and silver operation, Khoemacau Copper Mining, looks promising as the new owners, MMG Group, commit to the mine’s expansion plans. MMG, an Australian headquartered company owned by China, has expressed its dedication to doubling Khoemacau’s production and transforming it into one of the most significant high-grade copper operations in Africa.
Nan Wang, the Executive General Manager for Australia and Africa at MMG, stated that while the immediate focus is on maintaining a consistent production level of 60ktpa, there are solid plans to increase Khoemacau’s production capacity. The company aims to double its production from 3.65Mtpa to 8.15Mtpa, resulting in an increase in payable copper from approximately 60ktpa to around 130ktpa.
To achieve this expansion, Khoemacau has completed a pre-feasibility study on the project and a solar power initiative. The next step is to conduct a feasibility study, which will pave the way for increased production capacity. Additionally, Khoemacau has identified extensive exploration opportunities across its license area, positioning the company for an exciting new phase of development.
The current Khoemacau operation reached full production and nameplate capacity in December 2022, following over a decade of investment totaling over P10 billion. This significant investment allowed for an intense exploration program, resulting in the development of the most automated underground mining operation in Botswana. The first concentrate was produced in June 2021, and the product entered the export market in July of the same year. Throughout 2022, the company has been working on the pre-feasibility study for the expansion project, with the feasibility study scheduled for the following year.
The expansion plans will involve the construction of a new world-class process plant in Zone 5, where the current mining of ore takes place. This new plant will be larger than the existing one in Boseto, which currently receives ore from Zone 5. The expansion will also involve the development of new underground mines, including Mango, Zone 5 North, and Zeta North East. These additional mines will bring the total number of underground shafts at Khoemacau to six. The ramp-up of production from the expansion is expected to occur in 2026.
Khoemacau, which acquired assets in the Kalahari Copper Belt after the liquidation of Discovery Metals in 2015, currently employs over 1500 people, with the majority being Batswana. The Khoemacau Mine is located in north-west Botswana, in the emerging Kalahari Copperbelt. It boasts the 10th largest African Copper Mineral Resource by total contained copper metal and is one of the largest copper sedimentary systems in the world outside of the Central African Copperbelt.
The mine utilizes underground long hole stoping as its mining method and conventional sulphide flotation for processing. Resource drilling results have shown the existing resources to have continuity at depth, and there are several exploration targets within the tenement package that have the potential to extend the mine’s life or increase productivity.
The Zone 5 mine has already ramped up production, and further expansion in the next five years will be supported by the deposits in the Zone 5 Group. The estimated mine life is a minimum of 20 years, with the potential to extend beyond 30 years by tapping into other deposits within the tenement package.
In conclusion, the commitment of MMG Group to Khoemacau’s expansion plans signifies a bright future for Botswana’s largest copper and silver operation. With the completion of pre-feasibility and feasibility studies, as well as significant investments, Khoemacau is poised to become one of Africa’s most important high-grade copper operations. The expansion project will not only increase production capacity but also create new job opportunities and contribute to the economic growth of Botswana.

The country has abundant coal reserves, and the government fully supports the commercial extraction of coal bed methane gas for power generation. The government guarantees that BPC will purchase the generated electricity at reasonable tariffs, providing cash flow to the developers and enabling them to raise equity and debt funding for gas extraction development.
Moagi highlighted the benefits of developing a gas supply industry, including diversified primary energy sources, economic diversification, import substitution, and employment creation. He commended Sekaname Energy for undertaking a pilot project to prove the commercial viability of extracting coal bed methane for power generation. If successful, this initiative would unlock the potential of a gas production industry in Botswana.
Sekaname Energy CEO, Peter Mmusi, emphasized the multiple uses of natural gas and its potential to uplift Botswana’s economy. In addition to power generation, natural gas can be used for gas-to-liquids, compressed natural gas, and fertilizer production. Mmusi revealed that Sekaname has already invested $57 million in exploration and infrastructure throughout its resource area. The company plans to spend another $10-15 million for the initial 6MW project and aims to invest over $500 million in the future for a 90MW power plant. Sekaname’s goal is to assist BPC in becoming a net exporter of power within the region and to contribute to Botswana’s transition to cleaner energy production.
In conclusion, the power purchase agreement between BPC and Sekaname Energy for the production of power from coal bed methane in Mmashoro village is a significant step towards diversifying Botswana’s energy mix. This project aligns with BPC’s strategic initiatives to increase the proportion of low-carbon power generation sources and renewable energy. The government’s support for the development of a gas supply industry and the commercial extraction of coal bed methane will bring numerous benefits to the country, including economic diversification, import substitution, and employment creation.
