Aim-listed Keras Resources has concluded the bulk sample agreement for its flagship Nayega manganese project, in northern Togo, which confirms all the technical, financial and logistical assumptions of Keras’ internal feasibility study. The agreement, which concludes six months of work by Keras and Togo authorities, will underpin the success of Nayega over the next decade and provide robust cashflows going forward, Keras CEO Russell Lamming said in a statement issued on Monday.
