19 April 2017
STRONG RESOURCE POTENTIAL AT HIPPOLYTE SOUTH INDICATED BY ULTRA DETAILED GROUND
RADIOMETRIC SURVEY
INDICATES A STRONGLY MINERALISED ZONE SIMILAR
TO 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.
