Aura Energy (ASX: AEE) is a uranium explorer with advanced projects in Sweden, West Africa and Australia. The company is focusing on two main projects: the Storsjön Project located in Sweden’s Alum Shale Province, one of the largest depositories of uranium in the world; and the highly prospective Reguibat Project in Mauritania.
Aura Energy’s main projects in Sweden are based on the Alum Shales, which have been historically known as one of the largest depositories of uranium in the world. Aura Energy has exploration permits and applications in three regions in west Africa: the Reguibat Craton in Mauritania, the Mauritanide Fold belt in Mauritania, and the Tim Mersoi Basin in Niger.
Aura Energy to commence stage 2 bioleaching at Häggån project in Sweden
With positive results from stage 1, Aura Energy (ASX: AEE) has commissioned stage 2 which includes testing using bioleach technology for the extraction of uranium and other metals from the Häggån project, located in Sweden’s Alum Shale Province, one of the largest uranium deposits in the world.
The aim of the work is to determine the optimal process route for Aura’s giant uranium deposit at the Häggån project, in order to secure enhanced extraction of uranium, molybdenum and nickel from the Alum Shale.
This next stage will work with larger samples, a range of acidities and will test agglomeration as a means of enhancing permeability.
Bob Beeson, managing director, said “This next stage of work is built on the encouraging results of stage 1 and is another step closer to choosing an extraction method for uranium and other metals found within the Häggån project."
The company prefers the bioleach technology approach as capital and operating costs can be low in comparison with other technologies.
Preparatory work is expected to be completed in January with all bioleaching results expected by June 2011.
