Mine Life37 years (as of Jan 1, 2019)
On 16 December 2022, the Company lodged an amendment to its existing application for an exploitation licence for the Kvanefjeld Project in Greenland to the Mineral Resource Authority. The amendment supplements the Company's existing application to include an alternative development scenario. Specifically, under the alternative development scenario the Company will exploit only rare earth elements, zinc and fluorspar (and not uranium).

The Company maintains its original exploitation licence application, by which it continues to apply for an exploitation licence for the Kvanefjeld Project inclusive of uranium exploitation rights. The Company has confirmed this to the Greenland Government along with its expectation that the Greenland Government will continue to process its exploitation licence application on that original basis.

Deposit Type

  • Magmatic


Summary:

The lujavrite series within the Ilimaussaq\ Complex is at least 500 m thick and are generally fine-grained and laminated but there are locally some medium to coarse-grained pegmatoidal varieties. Black (arfvedsonite bearing) lujavrite is the rock type that hosts REE, uranium, and zinc multi-element mineralisation. Economic REE and uranium grades occur in the uppermost sections of the lujavrites, and are associated with distinct ore minerals. Mineralisation is predominantly orthomagmatic, with metal enrichment a function of differentiation of the lujavrite magma.

Steenstrupine is the most important host to both REEs and uranium in the lujavrite-hosted deposits. It is a complex sodic phospho silicate mineral. Mineralogical studies suggest that steenstrupine commonly contains between 0.2% and 1% U3 O8 , and greater than 15% total rare earth oxide. Steenstrupine is the dominant host to both uranium and REEs. The phosphorous in the mineral structure makes steenstrupine amenable to concentration by conventional flotation techniques.

The grain size of the steenstrupine commonly ranges from 75 µm to over 500 µm. Other minerals that are important hosts to REEs include the phosphate mineral vitusite and, to a lesser extent, britholite, lovozerite group minerals and rare monazite. Aside from steenstrupine, uranium is also hosted in zirconium silicate minerals of the lovozerite group. In these silicates a portion of the zirconium is substituted by several hundred p ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The mining operations involve conventional open pit mining via blasting followed by truck/shovel haulage. Ore will be transported to a concentrator to produce rare earth phosphate concentrate (REP), zinc concentrate and fluorspar. The zinc concentrate and fluorspar will be sold and the REP further processed in a refinery to produce REE products and uranium oxide. All saleable products will be transported to the Port and exported. Overburden from the mine will be stored in a waste rock stockpile (WRS). Tailings from the concentrator and refinery will be stored within a tailings storage facility (TSF).

The mine has been designed in consideration of its environmental setting. The Kvanefjeld deposit is located on a plateau at an elevation of 600 m, with the orebody outcropping at surface and the highest grade material occurring in the upper zones.

The mine will have an open pit design with 10 m wide benches. Mining will be a standard drill-blast-truck-shovel operation. This configuration has been identified as the lowest operating risk mining method, both in terms of cost and productivity. Ore will initially be hauled to the run of mine (ROM) pad located adjacent to the pit where it will be arranged in stockpiles. Ore selected from individual piles will be blended using a front end loader and the blended ore will be hauled in mine trucks to the concentrator, with an average haul distance of 1.5 km. The trucks will dump ore directly into the primary crusher.< ........
