STRONG RESOURCE POTENTIAL AT HIPPOLYTE SOUTH INDICATED BY ULTRA DETAILED GROUND RADIOMETRIC SURVEY

INDICATES A STRONGLY MINERALISED ZONE SIMILARTO HIPPOLYTE RESOURCE

A SEPARATE PROGRAM OF DOWNHOLE GAMMA LOGGING HAS PROVIDED CONFIRMATION OF PREVIOUS U3O8 GRADES

TECHNIQUE WILL BE USED IN RESOURCE UPGRADE DRILLING TO COMMENCE SHORTLY

Aura Energy Limited (AEE; ASX, AURA; AIM) is pleased to announce that recent field programs of both ultra-detailed ground radiometric surveying and of downhole gamma logging have resulted in two important outcomes for the Tiris Project currently under development by Aura Energy.

The first important outcome is that the Hippolyte South prospect which the company pegged following the completion of the Tiris Scoping study, has been surveyed using ultra-detailed ground radiometric methods and this has highlighted several strongly mineralised zones larger in area than Hippolyte Zone 1 which contains 4.6 million pound U3O8 as Inferred Resource.

In May 2015, Aura announced that it had made an application for a mineral exploration permit over an area of 224 km2 adjoining to the south of its important Hippolyte uranium resource.

The Hippolyte South permit area had indicated strong uranium responses in regional airborne radiometric data, similar in strength and size to those over Aura's nearby resources. The anomalies within this new tenement extend for more than 15 km and cover an area of approximately 10 km2.

In 2011, Aura carried out a brief reconnaissance drilling program over these radiometric highs as part of a possible JV arrangement over the area. This drilling was broadly spaced with holes 200 metres apart on lines 800 metres or more apart.

More than 25% of these reconnaissance holes intersected ore-grade mineralisation (i.e. at least one metre at 100 ppm U3O8 or greater) with values ranging up to 646 ppm U3O8 (see Figure 2). Details of results are set out in Table 1.

This latest survey is the first more detailed testing of the broad mineralised zones following the initial reconnaissance drilling and has confirmed the confidence in the prospect and indicated large zones of continuous uranium bearing mineralisation with strong similarities to Aura’s key Hippolyte uranium deposit.

Peter Reeve, Aura Energy's Executive Chairman said, “The indication of potential extensions to Aura’s Tiris Uranium Project resource position is extremely pleasing and highlights that Tiris is still at an early stage in our knowledge and understanding of the project. Tiris contains a large 49 million pound resource of uranium but as time goes on and we refine our methods and techniques the potential for new discovery in the Tiris field is high”.

Hippolyte Downhole Logging Success

The second important outcome is that a downhole gamma logging survey was conducted on 63 drillholes in the key Tiris Resource zone, Hippolyte Zone 1 and has validated previous drilling and sampling of the project. This coverage is shown in Figure 5.

The downhole gamma logging indicated U3O8 grades that compare well with grades determined by chemical assay. Aura will proceed to utilise downhole gamma logging in its next resource upgrade drilling which will commence next month aimed at converting more of the Tiris Resource into Measured and Indicated categories.

Competent Person

Dr Robert Beeson has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking. This qualifies Dr Beeson as a Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Dr Robert Beeson consents to the inclusion in the report of the matters based on his information in the form and context in which it appears. Dr Beeson is a member of the Australian Institute of Geoscientists.
