A preliminary technical and economic study of the Nohra-Elende potash project, in Germany, has a potential mine life of some 34 years.
ASX-listed Davenport Resources on Wednesday said that the study estimated an annual production of 575 000 t of muriate of potash, 640 000 t of kieserite monohydrate, and 1.2-million tonnes a year of industrial grade sodium chloride.
