Roan Front-End Module's First Copper Concentrate Produced Jubilee, a diversified metals producer with operations in South Africa and Zambia, is pleased to announce first production of copper concentrate from the Front-End Module at the Roan concentrator facility in Zambia following the announcement of commencement of production on 8 August 2024. The copper concentrate produced from Roan's Front-End Module, targeting previously mined material, will be refined to produce copper cathode at the Company's Sable refinery. The concentrate from the Front-End Module is in addition to the sulphide copper concentrate already being produced from Roan's mill-and-float circuit and currently traded in the market. The Front-End Module will be ramped up during Q3 CY2024. The Company's Zambian copper processing operational footprint now encompasses both the Roan mill-and-float circuit and Front-End Module, as well as the Sable Refinery, which is currently being upgraded for a combined in-country copper capacity in excess of 25 000 tonnes per annum. Leon Coetzer, CEO commented: "It is an exciting time at Jubilee as we commence delivering on our growth projects. The first upgraded concentrate produced from our processing modules is a significant milestone for the business allowing Jubilee to commence filling the available copper production capacity at our Zambian operations. I would like to extend my sincere gratitude to our dedicated team and stakeholders for their support in achieving this milestone." 13 August 2024 For further information visit www.jubileemetalsgroup.com, follow Jubilee on Twitter (@Jubilee_Metals) or contact: Jubilee Metals Group PLC Leon Coetzer (CEO) / Neal Reynolds (CFO) Tel: +27 (0) 11 465 1913 Nominated Adviser - SPARK Advisory Partners Limited Andrew Emmott/James Keeshan Tel: +44 (0) 20 3368 3555 PR & IR Adviser - Tavistock Jos Simson/ Gareth Tredway Tel: +44 (0) 207 920 3150 Joint Broker – RBC Capital Markets Farid Dadashev/Jamil Miah Tel +44 (0) 20 7653 4000 Joint Broker - Zeus Capital Harry Ansell/Katy Mitchell Tel: +44 (0) 20 7220 1670/+44 (0) 113 394 6618 JSE Sponsor - Questco Corporate Advisory Proprietary Limited Alison McLaren Tel: +27 (0)11 011 9207 About Jubilee Jubilee is a low-cost, diversified producer, specialising in the recovery of metal from previously overlooked resources, such as unprocessed historical waste rock, run-of-mine materials and tailings in South Africa and Zambia.
