Australia-based mining company Centrex Metals has partnered with CDE Meta to deliver a state-of-the-art wet processing plant, currently in transit to the company’s Ardmore site, that will produce phosphate concentrate, according to CDE.The plant is expected to arrive on site this month following the completion of fabrication and successful factory acceptance testing, CDE said.Located south of Mount Isa in northwest Queensland, Centrex Metals’ Ardmore phosphate rock project is expected to produce 776,000 t/y of premium-grade phosphate rock concentrate, according to a recent feasibility study.The pilot CDE phosphate washing plant, expected to be commissioned in the second half of 2019, will wash, scrub and de-slime free-digging ore to produce premium 35% P2O5 and ultra-low cadmium phosphate rock concentrate to be used in the manufacture of phosphoric acid, CDE said. It will progress to full-scale development in 2020.The modular plant has a capacity of 70 t/h and has been designed to accommodate the expansion of the plant in phase two, which is expected to double the scale of the operation to process 140 t/h, equivalent to 800,000 t/y (wet).During phase one, the pilot plant will provide up to 30,000 t (wet) concentrate to a number of Centrex Metals customers.A digital representation of the new Centrex Metals Ardmore phosphate plantAdam Holland, Head of Mining at CDE, said: “This 70 t/h solution, created in collaboration with Centrex, is part of a two-phase project. The pilot plant comprises the first phase and has been carefully designed using CDE’s unique modular offering in order to facilitate the simple and cost-effective transition to a 140 t/h plant in phase two.“CDE’s modular approach solved many of the challenges presented by the remote location of the reserve, providing the flexibility required to protect that initial investment when moving from a pilot to full scale plant in 2020. This was essential for Centrex Metals to gain the necessary return on investment to make the project viable.”To alleviate challenges presented by the remote location and its restricted access to water supplies, CDE is also supplying its AquaCycle technology, a high-efficiency water management system which recovers up to 90% of the process water for immediate recirculation in the system.The bespoke solution designed and commissioned by CDE has contributed to Centrex Metals reducing its pre-production capital costs by 13% due to key design changes and equipment selection.Simon Slesarewich, CEO at Centrex Metals, said: “This is an exciting development for Centrex and we look forward to receiving the first module of the start-up plant on site.“Following a thorough feasibility study, we expect to produce 776,000 t of premium grade phosphate rock concentrate, which is equivalent to 800,000 wet tonnes per annum at the target shipping level of 3% moisture.“To deliver this target over the estimated 10-year lifetime of the mine, we required a reliable and resilient wet processing solution to remove the fine gangue after the high-grade ore has been crushed to meet sizing specifications. Our research showed that CDE could deliver a solution that fully met our requirements.”He continued: “Trial mining and production will enable the company to demonstrate the quality of the Ardmore product and further advance the project with offtake partners in the Asia-Pacific region that is forecast to see increased growth with this quality of material.”
IronRidge Resources has entered a binding memorandum of understanding (MoU) with GeoDrill as part of a “drilling for equity program” of up to $4 million, or 40,000m of drilling at the exploration company’s gold and lithium portfolio throughout Africa.GeoDrill, established in 1998, is a leading exploration drilling company with a fleet of 67 drill rigs that has operations is Ghana, Burkina Faso, Côte d’Ivoire, Mali, and Zambia.The MoU will see IronRidge advance all projects across Ghana, Côte d’Ivoire and Chad, while maintaining cash resources, it said.IronRidge’s Chief Executive Officer, Vincent Mascolo, said: “We are delighted to announce that the agreement with GeoDrill secures access to expert drilling capabilities, which will allow the company to effectively advance its portfolios, whilst helping preserve cash resources.GeoDrill brings decades of operational expertise throughout West Africa and, with operational centres in both Ghana and Côte d’Ivoire, provides excellent synergies with the Ccmpany’s current jurisdictions of focus.”Dave Harper, Chief Executive Officer of GeoDrill, said: “Having previously worked with IronRidge on their Cape Coast lithium project and Côte d’Ivoire gold projects, we understand their exploration business model and it was an easy decision for us to partner with IronRidge in this drilling for equity program.”Under the terms of the binding MoU, any drilling services provided by GeoDrill will be paid by either; cash, shares, or a combination of cash and shares on a 50/50 basis at IronRidge’s election.The agreement is based on a competitive quotation process, which provides for the issue of ordinary shares in IronRidge for 50% of the drilling cost up to a value of $4 million in two $2 million stages.“The agreed payment mechanism comprises a share valuation of 90% of the 15-day volume weighted average price against the value of each monthly invoice,” IronRidge said.Geodrill has commenced drilling works in Ghana where approximately 13,200 m of drilling has been planned at the Cape Coast lithium project over a staged reverse circulation and diamond drilling program dependent on results. It is also currently continuing field mapping and sampling programs over the Zaranou gold project, in Côte d’Ivoire, ahead of a planned air-core drill program.In Côte d’Ivoire, IronRidge is assessing air-core results over its Bianouan and Bodite licences to determine the next steps as well as soils and trenching results over its Kineta and Marahui licences.“At this stage the company will maintain its focus on the Côte d’Ivoire gold portfolio and the Ghana lithium portfolio,” IronRidge said.
