Kvanefjeld Optimised Feasibility Study: Substantial 40% Capital Cost Reduction
HIGHLIGHTS:
-
Capital costs reduced by ~40% to US$505M, inclusive of refinery circuit
-
Rare earth production increased by 8%, inclusive of 5,692t NdPr, 270t Dy, 44t Tb oxides
-
Initial 37‐year mine life based on 108Mt ore reserve estimate
-
Industry leading capital intensity complements very low operating costs
Dr John Mair, Managing Director commented:
“With the completion of an outstanding optimisation program, we have a project with a smaller footprint producing more rare earths at lower operating costs, which requires significantly less capital for development.
The 40% reduction in the capital cost estimate together with the increased projected output over an initial 37‐year mine life results in the lowest capital intensity amongst our peers.
The optimised capital costs, when considered with operating costs after credits of below US$4/kg of rare earth oxide, creates a highly robust project and compelling development opportunity; a strong result for both Company shareholders and project stakeholders.”
Greenland Minerals Ltd (‘GML’ or ‘the Company’) is pleased to provide an updated capital cost estimate for the Kvanefjeld Project (the Project). The Project’s capital cost estimate has been reduced by 40% from US$832M (Company Announcement April 6[th] , 2016) to US$505M . The Kvanefjeld Project, 100% owned by GML, is underpinned by the largest code‐compliant (JORC or CIM) rare earth resource globally.
The reduction in the capital cost estimate is the result of optimisation studies covering all elements of the Project from the flowsheet to civil construction. The results of individual optimisation studies have been the subject of progressive updates to the market since 2016.

Improvements to the flowsheet include a major enhancement to flotation performance (the production of smaller volumes of higher‐grade concentrate) and the development of a simpler, more efficient leaching circuit. These improvements have been developed in close collaboration with the Company’s major shareholder, leading rare earth company Shenghe Resources Holding Co Ltd (Shenghe). In combination, these developments significantly reduce the scale of the refinery circuit resulting in substantial cost reductions.
Civil engineering design and construction costs were also a major focus of optimisation studies. A multi‐disciplinary team of specialist engineering firms including Nuna Logistics, Tetra Tech, PND Engineers and China Communications Construction Co. has contributed to an updated civil design with constructions costs reduced substantially (Company announcement March 26, 2019).
The updated capital cost of US$505M is transformational for the Project which now has the lowest capital intensity of emerging ASX‐listed rare earth projects.
In August 2018, GML and Shenghe entered a Memorandum of Understanding (MoU) addressing commercialisation of the Kvanefjeld Project. The MoU (non‐binding) addressed rare earth separation, off‐take and marketing, and project finance. Shenghe is an established producer of high‐purity rare earth oxides and metals with an international customer network (Company announcement August 21[st] , 2018).
Kvanefjeld’s standing as a world‐class rare earth project is bolstered by the new capital cost estimate, the recently announced revised operating costs, the Project’s potential multi‐decade duration and the globally significant production numbers.
Optimised Feasibility Summary
The Company released its Feasibility Study in 2016 (the Study). The Study was the last major Project study completed by the Company before Shenghe became a major shareholder. Since becoming a major shareholder, Shenghe has worked closely with the Company on the development and execution of the Company’s Study optimisation program.
A summary of the results of this optimisation program is set out below.
Process Plant
The Project’s main rare earth bearing mineral is steenstrupine which contains 25‐30% REO. In the 2016 Study the concentrator produced a mineral concentrate containing 14% rare earth oxide (REO). A key focus of the optimisation programme was to produce a smaller volume of a higher‐grade concentrate. With the guidance of Shenghe, metallurgical flotation specialist groups in China were engaged and these groups have developed an optimised flotation circuit producing rare earth mineral concentrates with grades in the range of 22 ‐ 25% REO. For the purposes of engineering design a concentrate grade of 22% was used.

==> picture [107 x 24] intentionally omitted <==
In addition, the method of concentrate refining has been simplified. The refinery now includes a single stage circuit and fewer solid‐liquid separation steps. The higher concentrate grade and the simplification of the refinery circuit has resulted in a reduction of the scale of the refinery circuit and the size of processing equipment in the refinery.
Technical developments arising out of the optimisation program have been summarised in a series of Company Announcements, inclusive of JORC Table 1 details (December 20, 2017; January 15, 2018; July 11, 2018; January 10, 2019).
Engineering design work for the optimised concentrator and refinery circuits has been completed and operating and capital costs have been updated.

Civil Construction
In the 2016 Study, civil construction costs represented a large proportion of overall capital costs. Another key focus of the Company’s optimisation programme was the reduction of construction costs in the civil design and project layout.
Nuna Logistics, cold climate civil construction specialists, have developed an updated estimate of civil construction costs based upon updated designs by Tetra Tech, PND Engineers and China‐CCC. Representatives from all four engineering firms visited the Project site in 2018 to gather site specific information to assess the project (Company announcement ‐ September 18[th] , 2018).
Cost reductions were primarily achieved through substantial reductions in civil earth works for site preparation (Company announcement October 22[nd] , 2018) updated port design by specialist groups, and greater use of local materials. The revised civil costs were reduced to US$175M including indirect costs and contingency. This is a reduction of US$138M (‐44%) of the civil construction cost estimate in the 2016 Feasibility Study (Company announcement March 26[th] , 2019).
The Company elected to use Nuna in the optimisation studies because of their cold climate experience, their excellent track record of involving the local community and their record of creating a positive legacy with all stakeholders.

Port
Direct shipping access is a key advantage for the Kvanefjeld Project, and efficient port facilities are important for year‐round materials handling and transfer. PND Engineers and China‐CCC have developed a new capital cost estimate for Project’s dedicated port facility. PND Engineers, specialists in cold climate port design, developed the design for the off‐shore aspects of the port facility. C‐CCC, that bring global port design expertise, provided the on‐shore elements of the port design.
Production Profile
The optimisation programmes in the process plant have increased rare earth production by approximately 8% to approximately 32,000 tpa of REO. The Project will be a major producer of rare earths, particularly the “magnet metals” ‐ Neodymium, Praseodymium, Terbium, and Dysprosium – which are critical to clean energy generation and efficient energy use. Of the increased production approximately 6,000t will be “magnet metals”.
Table 1 shows details of estimated annual “magnet metal” production after optimisation.

| Rare Earth | Annual Production ‐t |
|---|---|
| Praseodymium | ~1,400 |
| Neodymium | ~4,300 |
| Terbium | ~45 |
| Dysprosium | ~270 |
Capital Cost Estimate

Indirect costs have been estimated for temporary construction facilities and for engineering, procurement and construction (EPC) management.
A contingency of 15% was applied to both direct and indirect costs.
Using current spot prices for REO’s as of July 4[th] 2019, the basket price for project intermediate product is $15.32/kg REO . This basket price has been calculated using REE data from ACREI – the Association of China Rare Earth Industry. ACREI post daily prices in RMB for all REE which have been converted to USD at the daily prevailing exchange rate. The basket price has increased by 16%, since the Company announcement updating the project operating costs, released on May 15[th] , 2019.
Using GML’s forecast REE prices , the basket price for project intermediate product is $19.55/kg REO. This basket price has been calculated using REE data from ACREI and independent industry consultant Adamas Intelligence. Forecast prices for the “magnet metals” – Nd, Pr, Tb and Dy – have been taken from the latest industry report prepared by Adamas Intelligence and, for all other REE, the current spot prices have been used in the calculation.

ABOUT GREENLAND MINERALS LTD.
Greenland Minerals Ltd (ASX: GGG) is an exploration and development company focused on developing high‐quality mineral projects in Greenland. The Company’s flagship project is the Kvanefjeld Rare Earth Project (rare earth elements, uranium, zinc). A pre‐feasibility study was finalised in 2012, and a comprehensive feasibility study was completed in 2015 and updated following pilot plant operations in 2016. The studies highlight the potential to develop Kvanefjeld as a long‐life, low cost, and large‐scale producer of rare earth elements; key enablers to the electrification of transport systems.
GML is working closely with major shareholder and strategic partner Shenghe Resources Holding Co Ltd to develop Kvanefjeld as a cornerstone of future rare earth supply. An exploitation (mining) license application for the initial development strategy was reviewed by the Greenland Government through 2016 ‐17 and was updated in 2018 following addition supporting studies.
In 2017‐19, GML undertook technical work programs with Shenghe Resources Holding Co Ltd that improved the metallurgical performance and simplified the development strategy and infrastructure footprint in Greenland. This will enhance the project cost‐structure and ensure that Kvanefjeld is aligned with downstream processing. In addition, the Company continues its focus on working closely with Greenland’s regulatory bodies on the processing of the mining license application and maintaining regular stakeholder updates.
