| ABSTRACT: | Danakali Limited (“Danakali”, ASX:DNK) is pleased to announce that the kieserite content in the Colluli Project Resource has been quantified. Kieserite (“Magnesium sulphate monohydrate”, MgSO4.H2O) is a commonly used chloride free, multi-nutrient fertiliser with limited current primary production centres globally. The Colluli Mineral Resource Estimate completed by AMC Consultants demonstrates that the majority of the kieserite within the resource exists within the lower carnallitite layer, at a content of approximately 22%. Additional kieserite is contained within the upper carnallitite and kainitite layers of the resource. Kieserite was not reported as part of the Colluli Project Mineral Resource in 2015 as a recovery process had not yet been demonstrated. A recent metallurgical review has identified a potential process to recover kieserite from the Colluli tailings, after original test work demonstrated kieserite will report to the process plant tailings stream. The Resource estimate is based on drill hole assay data from the original exploration drilling campaign conducted from 2010 to 2012, with additional QAQC drilling in late 2014. The deposit was originally sampled using 100% diamond core from surface. A total of 103 diamond holes have been drilled into the deposit of which 102 holes had geological logging, assaying or geophysical logging and were available for resource estimation. Diamond core was cut in half using a diesel powered core saw. No water was used for lubrication or dust suppression to ensure no core dissolution occurred. Core selected for duplicate analysis was further cut as quartered core with both quarters submitted individually for analysis. | |
