ASX Release : World Class Colluli Project in Eritrea
Mining Contract expressions of interest complete for World Class Colluli Project
Danakali Limited (ASX:DNK) is pleased to advise that is has completed the expressions of interest (“EOI”) process for mining contractors for the Colluli Potash Project. The EOI phase is a precursor to the mining contract tendering process which will commence shortly.
Expressions of interest have been received from mining contracting firms based in Australia, South Africa, and the broader African continent. All parties have extensive experience in the African mining industry and specialise in open cut mining methods. The shortlisted parties will formally bid in a competitive tendering process using further refined and detailed pit designs and material movement schedules derived in the definitive feasibility study1. An appointment of a suitable industry service provider to further optimise and refine the mining schedule, in line with the front end engineering design (FEED) work which is currently underway, will be made in the very near future.
The mining method, which includes the use of conventional haul trucks, excavators and surface miners was established during the Colluli feasibility studies after a series of economic trade-off evaluations. Surface miners are highly suitable for salt mining and provide a high degree of selectivity. This is highly advantageous for managing the suite of sodium, magnesium and potassium salts within the Colluli resource. The use of surface miners negates the need for primary crushing within the processing plant and completely eliminates the need for explosives in the mining operations. The open cut mining method also provides superior resource to reserve conversion in contrast with the alternate potash mining methods of underground and solution mining. The mining operation will generate a low waste to ore ratio of approximately two to one.
Colluli is the most advanced stage greenfield primary sulphate of potash (SOP) project in the world. Pre- construction activities including the front end engineering design process and advancement of major operational contracts are progressing well whilst funding and offtake discussions continue. Power generation bids have been received and are currently under evaluation.
Managing Director, Paul Donaldson said “This is another significant step in our pre-construction activities and we now look forward to the final refinement and optimisation of the mining schedules to support the mining contract bidding process. This is a critical operational contract for the project, and we are very pleased to have a high-quality group of candidates to progress to the competitive bidding phase.”
Danakali Limited, in conjunction with the Eritrean National Mining Corporation (“ENAMCO”), is developing the world class Colluli Potash Project located in the Danakil region of Eritrea, East Africa. Colluli is the largest and shallowest known evaporite deposit in the world with a solid form ore reserve estimate of over 1.1bn tonnes2.
Permitting for the project was completed in February 2017, providing the Colluli Mining Share Company (“CMSC”) exclusive rights to apply for mining licenses within the Colluli tenements. Mining licenses have also been granted3.
Colluli is the most fundable and economically attractive advanced stage SOP greenfield development in the world. The project demonstrates outstanding economics including industry leading capital intensity, bottom quartile operating costs, close proximity to coast and key markets and unrivalled product diversification potential.
Globally recognised, and highly reputable engineering and construction firm, Fluor was appointed as the lead for the FEED process for the project4. The FEED team is also supported by Global Potash Solutions, Knight Piésold and Elemental Engineering.

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

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-, SO42-, 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.
