Berkeley Energia Ltd.: High grade intercepts below Zona 7 point to resource upgrade
(firmenpresse) - High grade intercepts below Zona 7 point to resource upgrade
Additional high grade intersections have been recorded below the Zona 7 deposit, further supporting previous indications of continuity of mineralisation beneath the current defined resource.
Results from a further four holes drilled through the near-surface Zona 7 deposit and extended 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:
- 14 metres (at) 1,776 ppm U3O8
- incl. 8 metres (at) 2,644 ppm U3O8
- 26 metres (at) 1,103 ppm U3O8
- incl. 4 metres (at) 3,973 ppm U3O8
- 10 metres (at) 635 ppm U3O8

- incl. 2 metres (at) 1,204 ppm U3O8
- 17 metres (at) 563 ppm U3O8
- incl. 2 metres (at) 1,160 ppm U3O8
The drilling at Zona 7 is part of the ongoing exploration programme across numerous key targets at the Salamanca project.
The drilling beneath Zona 7 complements three holes drilled earlier this year in which broad, high grade intersections were reported at up to 14 metres (at) 4,481 ppm U3O8 (please refer to announcement on 27 January 2016).
Managing Director Paul Atherley commented:
Given the transformational effect the shallow, high grade Zona 7 deposit has had on the projects economics the primary focus of the current exploration program has been to look for more of the same. Further high grade intercepts located immediately below Zona 7 are extremely encouraging and point to potential resource upside at the deposit.

Appendix A: Detailed Results
Drill Programme
A total of 83 reverse circulation (RC) drill holes for 5,900 metres have been completed to date as part of a programme which was designed primarily to test for mineralization beneath and to the southern extension of Zona 7 as well as to test a number of targets located within a ten kilometre radius of the planned Retortillo plant.
The majority of holes drilled were spaced 50 metres apart along each section, with 400 metres spacing between sections.
Analytical data has been received from four of the completed holes and the results are presented herein, with the remaining results to be released when received.
A further eight holes will be completed in the coming two months, all targeting mineralisation below the Zona 7 deposit, and will be reported once assays have been received.
The drilling programme is part of a strategy aimed at maintaining annual production at the Salamanca Project at over 4 million pounds a year on an ongoing basis, achieved by converting some of the 29.6 million pounds of existing Inferred resources into the mine schedule, as well as extending the resource at Zona 7, and making new discoveries in the region.
Results
The holes reported herein were drilled through the near-surface Zona 7 deposit and extended to a maximum end-of-hole depth of 271 metres. The assay results confirm the presence of zones of high grade mineralisation below Zona 7. (Figure 1)
Significant high grade intersections have been recorded near surface at Zona 7 and at depth (from 3 metres to a maximum depth of 255 metres), with thicknesses up to 26 metres. Selected intercepts include:

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 (Figures 1, 2 and 3). 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.
