DRILLING CONFIRMS BROAD HIGH GRADE MINERALISATION AT ZONA 7
Initial results from the recently completed infill drill
programme at the Company's 100% owned Salamanca Project have
confirmed the continuity of the high grade mineralisation at the
important Zona 7 deposit.
Assay results from an initial 39 drill holes have shown that the
continuity of the mineralised zone is good and in line with
expectations, both in terms of grade and thickness. Significant
high grade intersections have been recorded at shallow depths (from
7 metres), with thicknesses up to 40 metres. Outstanding intercepts
include:
-- 40 metres @ 949 ppm U(3) O(8)
-- 26 metres @ 1,103 ppm U(3) O(8)
-- 22 metres @ 1,257 ppm U(3) O(8)
-- 21 metres @ 1,150 ppm U(3) O(8)
-- 8 metres @ 1,173 ppm U(3) O(8)
-- 6 metres @ 1,422 ppm U(3) O(8)
-- 5 metres @ 1,800 ppm U(3) O(8)
The majority of the results are from holes drilled into the
southern area of the deposit which was previously considered to be
lower grade compared to the high grade core of Zona 7.
The infill drill programme comprised 90 RC holes for 6,226
metres and was designed to upgrade the resource to the Indicated
category and also to test for extensions to the known
mineralisation.
The Zona 7 deposit is located within 10 kilometres of the
approved location of the proposed processing plant and currently
hosts an Inferred Mineral Resource Estimate of 23.2 million tonnes
averaging 589 ppm U(3) O(8) for 30.1 million pounds of U(3) O(8)
(at a 200 ppm U(3) O(8) cut-off grade). Results from all remaining
holes are due to be reported in September along with an upgraded
Mineral Resource Estimate.
As previously advised given the very positive impact the Zona 7
resource is expected to have on the project's overall economics the
Board has decided to push ahead with the permitting required to
rapidly incorporate this resource into the overall development
plans.

Appendix A: Detailed Results
Drilling Programme
The current drill programme, comprising 90 RC holes for 6,226
metres, has been designed to close the broadly spaced 2014 drill
pattern down to a notional 50 metre by 50 metre grid to facilitate
the estimation of a revised Indicated Mineral Resource Estimate
('MRE') for the higher grade portion of the Zona 7.
Drilling Results
Assay results from the initial 39 RC holes from the 2015
drilling programme at Zona 7 are presented in this report. The
majority of the holes reported have been drilled in the southern
area of the current MRE or outside the resource boundary to the SE
and SW, with some holes drilled into the high grade core of Zona
7.
The mineralisation intersected in the drill holes has confirmed
the continuity of thickness and grade above the 200 ppm U(3) O(8)
cut-off reported in the current MRE. Significant high grade
intersections have been recorded at shallow depths (from 7 metres
to a maximum depth of 87 metres), with thicknesses up to 40 metres.

Geological Setting
Zona 7 is a vein type deposit hosted in a sequence of fine
grained metasediments which are overlain by a conglomerate unit and
adjacent to a granite intrusive. The mineralised envelope is
generally sub-horizontal and the mineralisation is contained within
a stockwork of veins. The uranium mineralisation occurs both within
the partially weathered zone and fresh rock.

Geology Deposit type, geological The uranium mineralisation

mineralisation. metasediments adjacent to granite.
The mineralisation typically
occurs as a sub-horizontal
to shallowly dipping layer
occurring between surface and
100m depth. The style of the
uranium mineralisation includes
veins, stockwork and disseminated
mineralisation in joint/fracture
filling associated with brittle
deformation. Uraninite and
coffinite are the primary uranium
minerals. Secondary uranium
mineralisation is developed
in "supergene-like" tabular
zones corresponding to the
depth of weathering. Most of
the mineralisation is hosted
within partially weathered
and unweathered metasediment.
This deposit falls into the
category defined by the International
Atomic Energy Association (IAEA)
as Vein Type, Sub Type Iberian
