AMC appointed to Support Colluli Mining Contract Tendering Process and Optimise Mine Schedule

Danakali Ltd. (OTCMKTS: SBMSF) and the Eritrean National Mining Corporation (“ENAMCO”) are pleased to advise that AMC Consultants has been appointed to support the mining contract tendering process and conduct refinement and optimisation work on the definitive feasibility study (“DFS”) mine schedule. The revised and optimised schedule will be aligned to the revised expected processing plant output of 472kt per annum per module following a comprehensive debottlenecking exercise in the front-end engineering design (“FEED”) optimisation phase. An additional 47kt per annum of expected product capacity (per module) was liberated through a full evaluation of the internal mineral processing units in the DFS design and systematic debottlenecking exercise.
Following the completion of the DFS, a number of recommendations made in the mining studies have been completed, providing input data which will now allow further refinement and optimisation of the mining schedule. Refinement of the early years of the DFS mining schedule to a higher level of granularity is required for the mining contract tendering process.
An expression of interest (“EOI”) process for mining contractors was recently completed, indicating strong interest from service providers to participate in a competitive tendering process.
The project, which is 100% owned by the Colluli Mining Share Company (“CMSC”), is advancing funding, offtake and pre-construction activities. Colluli is at the most advanced stage of development for a greenfield primary sulphate of potash (“SOP”) project in the world. The Mining Agreement was signed and Mining Licenses for the project were granted in February 2017.
About Danakali Ltd
Danakali is an ASX listed company and 50% owner of the Colluli Potash Project in Eritrea, East Africa. The company is currently developing the Colluli Project in partnership with the Eritrean National Mining Corporation (ENAMCO).
The project is located in the Danakil Depression region of Eritrea, and is ~75km from the Red Sea coast, making it one of the most accessible potash deposits globally. Mineralisation within the Colluli resource commences at just 16m, making it the world’s shallowest potash deposit. The resource is amenable to open pit mining, which allows higher overall resource recovery to be achieved, is generally safer than underground mining and is highly advantageous for modular growth.
The company has completed a definitive feasibility study for the production of potassium sulphate, otherwise known as SOP. SOP is a chloride free, specialty fertiliser which carries a substantial price premium relative to the more common potash type; potassium chloride. Economic resources for production of SOP are geologically scarce. The unique composition of the Colluli resource favours low energy input, high potassium yield conversion to SOP using commercially proven technology. One of the key advantages of the resource is that the salts are present in solid form (in contrast with production of SOP from brines) with which reduces infrastructure costs and substantially reduces the time required to achieve full production capacity.
The resource is favourably positioned to supply the world’s fastest growing markets.
Our vision is to bring the Colluli project into production using the principles of risk management, resource utilisation and modularity, using the starting module as a growth platform to develop the resource to its full potential.
Competent Persons Statement (Rock Salt Resource)
Colluli has a JORC 2012 compliant Measured, Indicated and Inferred Mineral Resource estimate of 347Mt @97% NaCl. The resource contains 28Mt @ 97% NaCl of Measured Resources, 180Mt @ 97% NaCl of Indicated Resources and 139Mt @ 97% NaCl of Inferred Resources.
The information relating to the Colluli Rock Salt Mineral Resource estimate was compiled by Mr. John Tyrrell. Mr. Tyrrell is a member of the Australasian Institute of Mining and Metallurgy (AusIMM) and a full-time employee of AMC. Mr. Tyrrell has more than 25 years’ experience in the field of Mineral Resource estimation. He has sufficient experience relevant to the style of mineralisation and type of the deposit under consideration, and in resource model development, to qualify as a Competent Person as defined in the JORC Code.
Mr Tyrrell consents to the inclusion of the information relating to the rock salt Mineral Resource in the form and context in which it appears.
Competent Persons Statement (Sulphate of Potash Resource)
Colluli has a JORC 2012 compliant Measured, Indicated and Inferred Mineral Resource estimate of 1,289Mt @11% K20. The resource contains 303Mt @ 11% K20 of Measured Resources, 951Mt @ 11% K20 of Indicated Resources and 35Mt @ 10% K20 of Inferred Resources.
The information relating to the 2015 Colluli Mineral Resource estimate was compiled by Mr. John Tyrrell, under the supervision of Mr. Stephen Halabura M. Sc. P. Geo. Fellow of Engineers Canada (Hon), Fellow of Geoscientists Canada, and as a geologist with over 25 years’ experience in the potash mining industry. Mr. Tyrrell is a member of the Australian Institute of Mining and Metallurgy and a full-time employee of AMC. Mr. Tyrrell has more than 25 years’ experience in the field of Mineral Resource estimation.
Mr. Halabura is a member of the Association of Professional Engineers and Geoscientists of Saskatchewan, a Recognised Professional Organisation (RPO) under the JORC Code and has sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code).
Mr. Tyrrell & Mr. Halabura consent to the inclusion of information relating to the 2015 Resource Statement in the form and context in which it appears.
Competent Persons Statement (Sulphate of Potash Reserve)
The November 2015 Colluli Ore Reserve is reported according to the JORC Code and estimated at 1,113Mt @10% K2O Equiv. The Ore Reserve is classed as 286Mt @ 11% K2O Equiv Proved and 827Mt @ 10% K2O Equiv Probable.

Quality Control and Quality Assurance
Danakali Exploration programs follow standard operating and quality assurance procedures to ensure that all sampling techniques and sample results meet international reporting standards. Drill holes are located using GPS coordinates using WGS84 Datum, all mineralisation intervals are downhole and are true width intervals.
The samples are derived from HQ diamond drill core, which in the case of carnallite ores, are sealed in heat sealed plastic tubing immediately as it is drilled to preserve the sample. Significant sample intervals are dry quarter cut using a diamond saw and then resealed and double bagged for transport to the laboratory.
Halite blanks and duplicate samples are submitted with each hole. Chemical analyses were conducted by Kali-UmwelttechnikGmBHSondershausen, Germany utilising flame emission spectrometry, atomic absorption spectroscopy and ionchromatography. Kali- Umwelttechnik (KUTEC) Sondershausen1 have extensive experience in analysis of salt rock and brine samples and is certified according by DIN EN ISO/IEC 17025 by the Deutsche AkkreditierungssystemPrüfwesen GmbH (DAR). The laboratory follows standard procedures for the analysis of potash salt rocks chemical analysis (K+ , Na+ , Mg2+, Ca2+, Cl- , SO4 2- , H2O) and X-ray diffraction (XRD) analysis of the same samples as for chemical analysis to determine a qualitative mineral composition, which combined with the chemical analysis gives a quantitative mineral composition.
