Jubilee Metals advances Zambian sopper strategy with successful Roan trials
Jubilee Metals Group, a diversified metals producer with operations in South Africa and Zambia, on Wednesday said it has successfully completed extensive processing trials at its Roan Concentrator, securing a long-term feedstock supply agreement that commenced production this week.
This milestone strengthens Jubilee's copper production profile and supports its ambition to capitalize on rising copper prices.
The Roan trials demonstrated Jubilee's ability to process high-grade shallow transitional copper reefs, previously considered waste or too complex by other operators. Achieving copper yields of approximately 65% and a minimum grade of 1.4% Cu, the trials confirm Roan's capacity to handle 35 000 to 40 000 tonnes per month (tpm) of run-of-mine (ROM) material, producing 240 to 360 tpm of copper units. These results bolster confidence in Jubilee's Large Waste Project, which holds an estimated 260 million tonnes of similar transitional copper ore at surface.
At its Munkoyo mining operations, Jubilee is maintaining a mining rate of 80 000 tpm, with 3 500 tpm of high-grade ROM (exceeding 2.5% Cu) delivered to the Sable Refinery, equivalent to 88 tpm of copper units. The company aims to increase this to 4 500 tpm (112 tpm copper units) by June 2025 and 8 500 tpm (212 tpm copper units) by October 2025. Lower-grade material (0.7% Cu) is stockpiled for future processing, with pilot trials underway for two 30,000 tpm modular processing units targeting 350 tpm of copper units by Q1 2026.
Jubilee is also advancing Project G, with resource drilling set for June 2025 to support an open-pit expansion. The company has secured exclusive due diligence rights for two additional near-surface mining properties, reinforcing its growth strategy. Additionally, Jubilee completed a $12.3 million (R220m) sale of a non-core waste asset, payable over 20 months, and initiated a $6.75m trade of 10 million tonnes from its Large Waste Project, with initial payments received.
CEO Leon Coetzer said, 'Our focus on transitional copper reefs, available in vast quantities, positions us to benefit from appreciating copper prices. The Roan trials have validated our processing capabilities, and with secure power and supply agreements, we are poised for stable growth.'
The Sable Refinery expansion, delayed to prioritise mining and trials, is scheduled for completion in quarter one 2026, increasing capacity to 14 000 tonnes per annum to accommodate production from Munkoyo, Project G, and other opportunities. Combined high-grade ROM from Roan and Munkoyo is expected to yield 288 tpm of copper units by June 2025, rising to 400 tpm by August and potentially 500-550 tpm by October.
Jubilee also announced the issuance of 5.96 million new shares to former chairperson Colin Bird to settle a £200 000 (R4.8 million) performance incentive, with shares locked for 12 months. The shares will be admitted to trading on AIM and JSE's Altx on or around June 3, 2025, increasing total issued capital to 3.07 billion shares.
Jubilee has also entered into negotiations with various parties to potentially invest into the construction of the targeted modular processing units for the Large Waste Project.
"The targeted companies offer more attractive investment terms under a partnership agreement approach than offered previously by the Abu Dhabi-based invest firm, which is preferred by Jubilee and is also non-dilutive for shareholders. Discussions over funding for processing plants on site at the Company's mining projects, also extend to the Large Waste Project," it said.
The share price was up 1.01% at R1 at midday on the JSE on Wednesday.

Jubilee Metals' Roan copper concentrator in Zambia achieves operational success
Jubilee Metals, diversified metals producer with operations in South Africa and Zambia, has full re-startedoperations at its Roan project in Zambia. Image: Supplied Jubilee Metals Group's Roan copper concentrator in Zambia is fully operational following an upgrade, exceeding July's targeted production by reaching 384 tons of copper units. The mining group, which aims to become a significant copper explorer, miner, and producer of concentrates and refined cathodes in Zambia, stated in an update on Wednesday that Roan's production in August was already above the targeted production rate of 350 tons. The Roan project, first announced by Jubilee in 2021 and upgraded in phases, is the cornerstone of the company's copper production ambitions alongside the Sable refinery. Jubilee is currently disposing of its South Africa-based chrome and platinum operations, with agreements in final form, and a shareholders' meeting is being scheduled soon. Jubilee's share price sank 5.4% to 70 cents on the JSE on Wednesday afternoon. 'I am pleased to report significant progress across our Zambia portfolio, which has all the assets we need to maintain momentum on our copper expansion strategy,' said Jubilee's CEO Leon Coetzee in a statement. He said that they were building a robust copper production profile by dedicating processing capacity at Roan to a combination of third-party sourced mined material and process tailings, while advancing the Munkoyo and Project G mining operations to feed an expanded Sable refinery.

Advertisement Next Stay Close ✕ Ad loading In addition, the Large Waste project is forging ahead, and the group's copper exploration footprint is being expanded. The Munkoyo and Project G mines are being developed to be the anchor source of copper material for cathode production at Sable. Further large-scale exploration properties have been secured, Coetzee said. Munkoyo consists of a series of nine open-pits, and resource drilling is underway to establish the potential of combining these pits into one large open-pit operation. The Large Waste tailings dump is understood to contain over 240 million tons. A review of the total surface stock portfolio was done. A monetisation program is underway to sell the lowest-ranking non-core tailings assets, with about an $18 million deal value already transacted over the past six months. Munkoyo's open-pit operation's drilling program has started, with an initial eight holes completed in partnership with a mining and exploration company. Drilling results are being reviewed, and early indications suggest potential to combine pits 2 to 4 into a single large open pit to offer increased mining flexibility and throughput. Discussions are in progress with a partner to further expanded Munkoyo and develop Project G while undertaking an exploration program of the new exploration properties. Jubilee's copper production for the first half was impacted by power and infrastructure challenges, and Roan was placed under care and maintenance. Following a successful Roan restart, copper unit production reached 757 tons in the second half, with annual production reaching 2 211 tons versus the guidance for the 2026 financial year of 5 100 tons. Further capital-dependent projects either underway or targeted to start next year could potentially increase annual copper production by about 10,000 tons. Coetzee stated that the energy-related challenges faced earlier this year helped them emerge with a clearer, more focused strategy backed by secure power supply and higher-value material supply agreements. Sable is undergoing an expansion to offer an annual processing capacity of about 14 000 tons of copper units upon completion, which is anticipated in the first quarter of next year. Mining at Munkoyo was temporarily halted for July and August 2025 while the extended pit design was completed based on the drilling results, and ore delivery to Sable is set to recommence in September 2025. On the Large Waste project, Jubilee plans to roll out a series of 25,000 tons per month modular processing units on-site, based on the design at Roan. BUSINESS REPORT

Ghana warns of power cuts while Italy's Eni works to boost gas supply
Italian energy group Eni will temporarily suspend operations at a gas plant in Ghana on Sunday to implement a supply increase, likely resulting in power cuts, the West African country said on Wednesday. Ghana, the world's second biggest cocoa producer, has been trying to ramp up oil and gas production to increase revenues and prevent fossil fuels from becoming stranded. It has reached a deal with Eni to increase natural gas supply by 30-million standard cubic feet per day to 270-million, the energy ministry said in a statement on X on Wednesday. To facilitate the upgrade, Eni will temporarily halt some operations, resulting in "an impact on the availability of gas for power generation", the statement said. Speaking at an event on Monday in the southern city of Kumasi, energy minister John Jinapor said Ghana was "likely to experience some interactions or interruption of power" while the plant was offline. "Once the work is done, we shall stabilise supply of gas, increase gas production and that will improve the delivery of power," he said. Eni's Offshore Cape Three Points project off Ghana's Atlantic coast meets 65% of the country's energy demand, according to the Italian company's website. Last week, Tullow Oil said in a statement it was planning to increase the supply of gas from its Jubilee and TEN projects to about 130-million standard cubic feet per day.

Jubilee Metals receives R1. 6 billion offer for its South African chrome and PGM operations
Jubilee Metals, a diversified metals producer with operations in South Africa and Zambia, has received a conditional binding offer from a private mining and metals trading company to acquire the group's chrome and platinum group metals operations in South Africa Image: Supplied Jubilee Metals, a diversified metals producer with operations in South Africa and Zambia, has received a conditional binding offer from a private mining and metals trading company to acquire the group's chrome and platinum group metals (PGM) operations in South Africa for a consideration of up to $90 million (R1.6 billion). The shares leapt 4.17% to R1.00 on Thursday morning on the JSE as investors welcomed the news. The offer allows Jubilee to sharpen its focus on expanding its copper strategy in Zambia while retaining exposure to the PGM market through its Tjate Platinum mining project. Under the terms of the offer, Jubilee will retain all current rights to the Tjate Platinum mining project offering Jubilee continued exposure to the potential upside of the PGM market, while focusing to further advance the Company's copper strategy in Zambia. The total consideration of up to $90m is payable through a combination of cash upfront and deferred cash payments over an approximate three year period. Jubilee's board has reviewed the offer and recognises its compelling value proposition. The company is also evaluating its dividend policy to potentially enable future distributions to shareholders. A detailed shareholder circular outlining the transaction will be issued soon. Absa Corporate and Investment Bank, a division of Absa Bank Limited, has been appointed as the financial advisor for the transaction. Strategic Focus on Copper in Zambia The disposal of the chrome and PGM operations allows Jubilee to prioritise its Zambian operations, where the company sees significant growth potential. Strong copper markets support higher earnings potential resulting in higher margins than that of chrome. It said, "With the anticipated continuing expansion of the world's growth in electrification generally, renewable power and automotive applications, demand for copper is expected to remain high. Jubilee has demonstrated its ability to successfully recover copper from shallow, transitional reefs. Recent trials confirm the Roan concentrator's capability to maintain a ROM feedstock run rate of between 35 000 to 40 000 tonnes per month (tpm) on the transitional reefs equating to 240 (at 35 000 tpm throughput and min Cu grade) to 360tpm of Cu units (at 40 000tpm and targeted Cu grade," Jubilee said. Jubilee recently continued to expand its near surface mining portfolio with the execution of two further agreements offering the exclusive right to perform its due diligence on these properties with the option to purchase the rights pending the outcome of the due diligence. Zambia holds additional potential opportunities which Jubilee seeks to secure. Jubilee's in country operational presence and processing know-how, positions Jubilee well to pursue these opportunities.
