Cyprium has a vision to become a significant mid-tier copper producer with a multi–asset strategy set to capitalise on the global electrification thematic. The Company’s strategy is to acquire, develop, operate and explore mineral resource projects using modern responsible methods to minimise environmental impact and optimise resource recovery and utilisation. Cyprium will make use of past investment to minimise capital intensity and lower risk to maximise the risk adjusted value of its projects. The Company has projects in the Paterson and Murchison regions of Western Australia that are host to multiple base metals deposits. Paterson Copper Projects This portfolio of copper projects comprises the Nifty Copper Mine, Maroochydore Copper Project and Paterson Exploration Project. The Nifty Copper Mine (“Nifty”) is located on the western edge of the Great Sandy Desert in the northeastern Pilbara region of Western Australia, approximately 330km southeast of Port Hedland. Nifty contains a 2012 JORC Mineral Resource of 940,200 tonnes of contained copper i. Cyprium is focussed on a business plan to develop a large open pit mine. Initially to provide ore to an existing heap leach SX-EW operation and to retreat the current heap leach pads. The restart of the existing copper concentrator to treat open pit sulphide material will commence once technical studies and approvals have been obtained for the larger operating footprint expected within 4 years. Combined target production rate is 65,000 tonnes of copper in cathode and concentrate. The Maroochydore deposit is located ~85km southeast of Nifty and includes a shallow 2012 JORC Mineral Resource of 486,000 tonnes of contained copper ii. Cyprium will commence a scoping studies targeting development of a +10 year 20,000 to 30,000 tonne per year copper metal producing leach-SXEW operation to commence once Nifty is fully developed and achieves stable profitable production. An exploration earn-in joint venture has been entered into with IGO Limited on ~2,400km2 of the Paterson Exploration Project. Under the agreement, IGO is to sole fund $32 million of exploration activities over 6.5 years to earn a 70% interest in the Paterson Exploration Project, including a minimum expenditure of $11 million over the first 3.5 years.
