AURA ENERGY NOTES EXCEPTIONAL GOLD DRILLING RESULTS BY ALGOLD AT TIJIRIT PROSPECT, MAURITANIA
AURA RECENTLY SECURED ADJACENT TENEMENTS TO ALGOLD (TSX) ON PRIME UNDER EXPLORED ARCHEAN GREENSTONE BELTS
AURA’S TASIAST SOUTH TENEMENTS OFFER MULTI MILLION OUNCE GOLD & BASE METAL POTENTIAL ALONG 45 KMs OF GREENSTONE BELT WITH STRONG DRILL RESULTS
Aura Energy Limited (ASX:AEE / AIM:AURA) the uranium development company focused on developing projects in Africa and Europe towards production, notes the exceptionally strong gold exploration results achieved by Algold Resources (TSX) at its Tijirit gold exploration prospect in Mauritania.
Aura’s prospects cover portions of the Tasiast and Tijirit Greenstone Belts adjoining the Algold tenement and have been only lightly explored by one other company which suspended activities despite having located zones of significant gold mineralisation. Members of Aura’s current technical team were involved in this previous work and are well acquainted with the area.
Peter Reeve, Aura Energy's Executive Chairman said “Aura remains extremely optimistic about its recently acquired gold prospects in Mauritania. The exceptional gold exploration results of Algold, and in the region generally, are compelling for the future of Aura’s gold exploration program given the similarity in the geological setting of each company’s tenements and the very limited exploration of these extensive greenstone belt packages (See Figure 2). With the large Tasiast Gold Mine on the same belt just north of our project, and a maiden gold resource and very positive drilling results emerging on the Algold ground, the potential for multi-million ounce discoveries, in the eyes of our technical people, is high".
Aura’s Tasiast South project consists of two tenements covering 175 km2 One tenement of 134 km2 lies 50 kilometres south of Kinross’ giant 21 Moz Tasiast Gold Mine, along strike on the same greenstone belt. (See Figure 1)
The second tenement of 41 km2 is adjacent to Algold tenement package which has recently been reporting spectacular drilling results in several locations. (See Figure 1)

Figure 4: Aura’s Ghassariat Zone location and gold anomalous zones defined by air core drilling
Air-core drilling to bedrock by the previous explorer located several anomalous gold zones, up to eight kilometres in length (See Fig 4). Of particular interest is Aura’s Ghassariat Zone, which has 1-3 g/t gold values on three of the four air-core traverses drilled. This anomaly extends over about eight kilometres parallel to the strike of the greenstone belt.
The Ghassariat Prospect intersections occur in strongly sulphidic and quartz-veined altered mafic volcanics and have marked similarities with some of the ore zones and near-ore alteration zones at the neighbouring Kinross Tasiast Mine (See Fig 5).
Drilling to date has generally been shallow with a near absence of deeper testing below the air core drilling. A very small number of RC holes have provided very good results however the density of drilling is very low averaging approximately one hole per 20 km2. A systematic program of infill drilling and drilling beneath existing positive drill results, and further shallow drilling on new targets is required to evaluate the long term potential on these tenements.
Intersections in the Ghassariat Zone reported by the previous explorer, in the only program of RC drilling completed, include:
TGRC 022 - 71m @ 0.3 g/t Au including:
TGRC 007 - 38m @ 0.4 g/t Au including:

The Tasiast gold mineralisation is in Archean greenstones with strong similarities in terms of rock types, structure and mineralisation style with the great gold provinces in the Archean belts of Australia and Canada in which there have been many hundreds of gold mines. In the Tasiast district there has only been one discovery, reflecting how little explored this belt is (See Fig 6). The Directors believe the potential for additional and substantial discoveries in the Tasiast district is very high.

Nickel and Base Metal Potential
While previous exploration on the Aura permits was directed at gold the work also located strongly anomalous nickel and copper/nickel values in several areas, associated with ultramafic rocks (See Figure 7). In parts of the tenements high nickel values are associated with anomalous copper highlighting potential for nickel-copper sulphide mineralisation, as also occurs in the greenstone belts of Australia and Canada. At this stage there has been no follow-up work carried out on these nickel targets.

Aura’s Chief Geologist, Neil Clifford, led the previous exploration in these areas, and has extensive and successful experience in international minerals discovery and deposit evaluation particularly in gold. He has played key roles in the discovery of at least 9 major mineral deposits in Australia, South America and Africa, for a variety of commodities including gold, uranium, copper and tin. These discoveries have included 20 million ounces of gold, including Sunrise Dam, and seven have subsequently become mines. He also played the lead role in the discovery of Aura's Tiris uranium deposits in Mauritania. He has been involved in West Africa since 2005.
References in this announcement to exploration results and potential have been approved for release by Mr Neil Clifford (Geologist and Member of the Australasian Institute of Mining and Metallurgy) who has more than 40 years relevant experience in the field of activity concerned. Mr Clifford is a Member of the Australasian Institute of Mining and Metallurgy. Mr Clifford has consented to the inclusion of the material in the form and context in which it appears.
