Greenland Minerals and Energy Ltd, is a mineral exploration and development company, focused on unlocking the mineral riches of Greenland, one of the world’s last natural resource frontiers. Our aim is simple; to identify large mineral deposits with the potential to underpin long term, economically robust mining operations. This is achieved through technically-focused exploration, aggressive resource development programs, and a strong understanding of the fundamentals that drive the business of mineral exploration and development globally.
Our flagship project is Kvanefjeld, a multi-element deposit located near the southwest tip of Greenland. Through focused exploration, Kvanefjeld is rapidly growing to become one to the world’s largest undeveloped deposits of rare earth elements, uranium and naturally occurring sodium fluoride, commodities with long term forecasts for strong demand increases.
Greenland Minerals & Energy technical work to boost rare earth elements recoveries and output at Kva
Greenland Minerals and Energy's (ASX: GGG, US-OTC: GDLNF.PK) key work programs on the efficient development of the Kvanefjeld multi-element project in Greenland are yielding positive results.
Over the last 18 months the company has been looking to improve the quality, grades and understanding of the mineral resources, to develop a highly effective method of beneficiating the Kvanefjeld ores, and improve the recovery of rare earth elements (REEs).
Significantly, the beneficiation testwork programs are now producing positive results with recent tests resulting in the concentration of >85% of light REEs in <15% of the mass. This effectively increases the grade fivefold.
This opens the opportunity for further reductions in the capacity and cost of the REE leach circuit while maintaining a high output, and will reduce the capital costs of the project.
Testwork to improve REE recoveries is also yielding positive results, with an overall increase in recovery of 17% achieved so far to date.
A new mine schedule has now been established following the recent release of an updated mineral resource estimate.
Importantly, under the base-case mining parameters, the new schedule sees an increase in REO output of 21% over the first 15 years of mining.
The company is aiming to establish an operation, which at full capacity will have an output of about 40,000 tonnes TREO (the rare earth elements of the lanthanide series and yttrium oxide).
In addition, the new mine schedule creates the opportunity to optimise the project economics by maintaining a high output while reducing the mine throughput and the size of the processing plant.
All technical developments serve toward establishing an increasingly cost-effective and efficient development scenario for the Kvanefjeld multi-element project. Work programs addressing mineral beneficiation and REE recoveries are ongoing.
The company said more results will be presented over the coming months, as it moves to firm up the optimal process flow sheet for the world’s largest JORC rare earth resource.
Greenland Minerals and Energy has a 619 million tonne (Mt) multi-element resource (rare earth elements, uranium, zinc) defined at Kvanefjeld, which was the first focal point of resource definition within the northern Ilimaussaq project area.
On June 15 Greenland Minerals and Energy said it is aiming to establish initial JORC Inferred resource estimates for three recently discovered multi-element deposits within the northern Ilimaussaq Complex in south Greenland by September.
With the global resource at Kvanefjeld including an inventory of 6.6 million tonnes of total rare earth oxides (TREO), the 2011 field program and Resource definition drilling will add to the company's Resource base in Greenland.
Over the next four months Greenland Minerals and Energy expects to announce further reductions to Kvanefjeld's capital costs and improvements in the project's economics.
