Häggån is located in central Sweden and is one of the largest undeveloped vanadium and polymetallic projects in the world. The project has a resource of 7,870 Mlbs V, 1,640 Mlbs Ni, 2,230 Mlbs Zn, 1,070 Mlbs Mo and 803 Mlbs U3O8.
The Häggån project is located in a sparsely populated area of swamp and forest used mainly for commercial forestry. Sweden’s has a current and active mining industry, with a clear regulatory position and a well-established path from exploration to production.
A Scoping Study was completed in May 2012 suggests that the Häggån Project has excellent potential to become a major, low cost producer of a suite of strategic 'green' metals. Aura’s discovery that the mineralisation is ideally suited to bioleach metal extraction was the major breakthrough to creating a robust and economic project. Bioleaching, including bioheap leaching, is a proven technology widely used in copper and gold industries with some application to the battery metals and uranium industry.
The Häggån Inferred Resource contains 2.35 billion tonnes at the grades shown in the table below. Metal content is also shown.
The project contemplated in the Scoping Study was a large scale heap leach with recovery of base metals as separate and high purity sulphide precipitates.
