Status: Scoping Study update complete


   Aura’s wholly owned Häggån Project is in the top two largest undeveloped uranium resources globally, covering 110 square kilometres in the Storsjön District in Central Sweden. The Häggån Project forms part of a large uranium field where the uranium occurs with molybdenum, nickel, vanadium and zinc in black shales. The first uranium operation from the Alum Shale began at Kvarntorp in southern Sweden in 1965. The shales form a near continuous sheet throughout the section of the project that Aura drilled in its 2008 -2011 programmes, with thicknesses ranging between 20 metres to more than 250 metres.

In August 2012, independent resource consultants Hellman & Schofield Pty Ltd established an upgrade to the JORC inferred resource at Häggån from 630 to 800 million pounds of uranium at 100ppm cut-off, with significant potential for further increases to the resource.

Aura conducted a review of its 2012 Häggån Scoping Study completed by independent consultants RMDSTEM Limited in late 2013 using smaller options than the original 30 million tonnes per annum used. Results demonstrated robust project financials with derived cash costs in the lower half of the uranium sector curve and confirmed the Häggån project has excellent potential to become a major, low cost producer of uranium, with by-products including nickel and other metals. View more information on the scoping study here.

In relation to metallurgical testwork, Aura has received exceptional results from two stages of bacterial heap leaching, with tests indicating up to 85% uranium extraction, as well as 58% nickel and 18% molybdenum. Bacterial heap leaching is a widely-used, low cost extraction technology which has demonstrated value at the Talvivaara nickel copper mine in Finland.
