Further high grade intercepts below Zona 7
Exploration Joint Venture Discussions
Berkeley Energia announces additional high grade intersections below the Zona 7 deposit at its 100% owned Salamanca mine in Western Spain.
Results from the final holes drilled in the current programme through the near-surface Zona 7 deposit to a maximum depth of 271 metres have reported grades consistent with, or higher than, the average grade of the Zona 7 resource.
Outstanding intercepts include:
-- 12 metres @ 1,003 ppm U(3) O(8)
incl. 1 metre @ 2,464 ppm U(3) O(8)
-- 2 metres @ 2,002 ppm U(3) O(8)
incl. 1 metre @ 3,761 ppm U(3) O(8)
-- 2 metres @ 1,357 ppm U(3) O(8)
This latest drilling supports the results from holes drilled over the past year in which high grade intersections up to 14 metres @ 4,481 ppm U3O8 were reported.
These results further demonstrate continuity of mineralisation beneath the current defined resource and potential for it to increase.
The Company will conduct additional drilling and resource estimation work at Zona 7 aimed at increasing the mineral resource estimate and unlocking further value in this exceptional deposit.
Exploration activity will focus on discovering mineralisation similar to the Zona 7 deposit which is located close to surface and without a strong radiometric anomaly present. Drill targets will be identified using a combination of techniques including ionic leach, ground geochemistry, radon emission and detailed structural mapping.
Exploration Joint Venture
The orebodies currently being developed cover just 7% of the Company's 1,160km(2) landholding within a highly prospective uranium region which remains largely underexplored.
Given the Company's current focus on the construction of the mine, discussions have commenced with strategic partners to fund an exploration joint venture designed to delineate additional resources to extend the mine life or expand production.
The partners would be expected to bring extensive multi commodity exploration experience and the very latest expertise that could be applied to the large body of structural and mineralising events at the project.
The exploration joint venture would cover only Berkeley's exploration tenements and would not affect ownership of deposits currently within the mine plan.
The Company will make an announcement if an agreement is executed. Alternatively, the Company will continue to pursue its own exploration activities aimed at extending the mine life or expanding production.
Managing Director Paul Atherley commented:
"These high grade intercepts immediately below Zona 7 are extremely encouraging and point to a potential resource upgrade, indicating that there could be still more upside to come from the Salamanca mine.
Given the transformational effect the shallow, high grade Zona 7 deposit has had on the project's economics we have designed the current exploration programme to look for more of the same, with a broader array of exploration techniques.
We are also excited about the potential to introduce an exploration joint venture partner who can draw on significant technical and financial resources and work with us to unlock the full potential of our 1,160km(2) landholding within this heavily mineralised province."

Appendix A: Detailed Results
Drill Programme
During 2016 the Company completed a detailed exploration programme aimed at maintaining annual production at the Salamanca mine at over 4 million pounds a year on an ongoing basis. The programme was designed primarily to test for mineralisation beneath and to the south of Zona 7 ("Zona 7 deeps programme"), as well as to test a number of targets located within a ten kilometre radius of the planned Retortillo plant ("regional targets programme").
The overall 2016 exploration campaign comprised 87 reverse circulation ("RC") drill holes, five diamond drill holes ("DDH") and two mixed (started in RC and finished in DDH) drill holes, for 8,200 metres.
The Zona 7 deeps programme included 17 holes. Initial results from the first three holes were reported on 27 January 2016 and a further set of four holes reported on 5 September 2016.
The regional targets programme included 80 holes and were drilled where radiometric anomalies were present. The majority of holes drilled were spaced 50 metres apart along each section, with 400 metres spacing between sections.
Analytical data has now been received from all holes completed during the 2016 Zona 7 deeps programme and the results are presented herein.
Results
The holes reported from the Zona 7 deeps programme were drilled through the near-surface Zona 7 deposit and extended to a maximum depth of 271 metres. The assay results confirm the presence of high grade mineralisation below Zona 7.
Significant high grade intersections have been recorded near surface at Zona 7 and at depth (from 3 metres to a maximum depth of 256 metres), with thicknesses up to 48 metres. Selected intercepts from the full Zona 7 deeps programme include:

(*) Drill holes failed to reach the target depth due to difficult ground conditions and were terminated
(**) Drill holes reported on 27 January 2016
(***) Drill holes reported on 5 September 2016
Note: Sampling and analysis for drill holes Z7M-195, Z7D-377, Z7D-378, Z7D-379, Z7D-380 and Z7D-381 was focussed on the potential zones of mineralisation below the existing Zona 7 resource. The mineralised zones within the existing resource were not sampled or assayed.
All significant intersections from completed holes from the Zona 7 deeps programme and all intercepts above 200 ppm from the regional targets programme, along with the details of the collar position, drill hole orientation and depth, are summarised in Appendix B.
Planned future exploration activity will be aimed at making new discoveries similar to the Zona 7 deposit which was discovered close to surface and without strong radiometric anomalism present over the bulk of the deposit. New drill targets will be identified using a combination of techniques including ionic leach, ground geochemistry, radon emission and detailed structural mapping.
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. In the southern extension the Cenozoic cover ranges between 1 metre and 12 metres.

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, although
mineralisation has been
recorded to a maximum depth
of 255m in the current RC
holes. 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

Atomic Energy Association
(IAEA) as Vein Type, Sub
