IRW-PRESS: Berkeley Energia Ltd.: Berkeley Energia Ltd.: Hochgradige Abschnitte unterhalb von
Zona 7 weisen auf Ressourcenhochstufung hin
Hochgradige Abschnitte unterhalb von Zona 7 weisen auf Ressourcenhochstufung hin
Unterhalb der Lagerstätte Zona 7 wurden weitere hochgradige Abschnitte entdeckt, was
frühere Hinweise unterstützt, wonach die Mineralisierung unterhalb der zurzeit definierten
Ressource weiterverläuft.
Die Ergebnisse von weiteren vier Bohrlöchern, die in der oberflächennahen
Lagerstätte Zona 7 gebohrt und auf eine maximale Tiefe von 271 Metern erweitert wurden,
lieferten gemeldete Gehalte, die mit dem Durchschnittsgehalt der Ressource Zona 7
übereinstimmen oder höher waren.
Die herausragenden Abschnitte beinhalten:
- 14 m mit 1.776 ppm U3O8
- einschl. 8 m mit 2.644 ppm U3O8
- 26 m mit 1.103 ppm U3O8
- einschl. 4 m mit 3.973 ppm U3O8
- 10 m mit 635 ppm U3O8
- einschl. 1 m mit 2.246 ppm U3O1
- 14 m mit 597 ppm U3O8
- einschl. 8 m mit 1.204 ppm U3O2
- 17 m mit 563 ppm U3O8
- einschl. 2 m mit 1.160 ppm U3O8
Die Bohrungen bei Zona 7 sind Teil des laufenden Explorationsprogramms bei zahlreichen wichtigen
Zielen beim Projekt Salamanca.
Die Bohrungen unterhalb von Zona 7 vervollständigen die drei Bohrlöcher, die in diesem
Jahr gebohrt wurden und in denen hochgradige Abschnitte von bis zu 14 Metern mit 4.481 Teilen pro
Million U3O8 gemeldet wurden (siehe Meldung vom 27. Januar 2016).
Managing Director Paul Atherley sagte:
Angesichts der vorübergehenden Auswirkung, die die oberflächennahe, hochgradige
Lagerstätte Zona 7 auf die Wirtschaftlichkeit des Projektes hatte, wird das Hauptaugenmerk des
aktuellen Explorationsprogramms darauf gerichtet werden, mehr davon zu finden. Weitere hochgradige
Abschnitte unmittelbar unterhalb von Zona 7 sind äußerst vielversprechend und weisen auf
eine potenzielle Ressourcenhochstufung bei der Lagerstätte hin.

Anhang A: Detaillierte Ergebnisse
Bohrprogramm
Im Rahmen des Programms, das ursprünglich konzipiert worden war, um eine Mineralisierung
unterhalb und südlich von Zona 7 zu suchen und um eine Reihe von Zielen innerhalb eines Radius
von zehn Kilometern der geplanten Retortillo-Anlage zu erproben, wurden bis dato 83
RC-Bohrlöcher auf insgesamt 5.900 Metern abgeschlossen.
Der Großteil der Bohrlöcher wurde in Abständen von 50 Metern entlang eines
Abschnitts gebohrt, wobei zwischen den Abschnitten ein Abstand von 400 Metern eingehalten wurde.
Die Analysedaten von vier der abgeschlossenen Bohrlöcher sind eingetroffen. Ein Teil der
Ergebnisse ist hierin angegeben, die restlichen Ergebnisse werden veröffentlicht, sobald sie
verfügbar sind.
In den kommenden zwei Monaten werden acht weitere Bohrlöcher abgeschlossen werden, die
allesamt die Mineralisierung unterhalb der Lagerstätte Zona 7 anpeilen. Die Ergebnisse werden
gemeldet, sobald sie verfügbar sind.
Das Bohrprogramm ist Teil einer Strategie zur Aufrechterhaltung der jährlichen Produktion
beim Projekt Salamanca von über vier Millionen Pfund, die erzielt werden wird, indem manche der
29,6 Millionen Pfund der bestehenden abgeleiteten Ressourcen in den Minenplan aufgenommen werden,
die Ressource bei Zona 7 erweitert wird und neue Entdeckungen in der Region gemacht werden.
Ergebnisse
Die hierin gemeldeten Bohrlöcher wurden durch die oberflächennahe Lagerstätte Zona
7 gebohrt und auf eine maximale Bohrlochtiefe von 271 Metern erweitert. Die Untersuchungsergebnisse
bestätigen das Vorkommen von Zonen mit hochgradigen Mineralisierungen unterhalb von Zona 7
(Abbildung 1).
Bei Zona 7 wurden in Oberflächennähe und in der Tiefe (zwischen drei und der maximalen
Tiefe von 255 Metern) bedeutsame hochgradige Abschnitte mit Mächtigkeiten von bis zu 26 Metern
verzeichnet. Ausgewählte Abschnitte beinhalten:

Geologische Beschaffenheit
Zona 7 ist eine erzgangartige Lagerstätte, die sich in einer Reihe feinkörniger
Metasedimente befindet, die unterhalb einer Konglomerateinheit und neben einer Granitintrusion liegt
(Abbildungen 1, 2 und 3). Die mineralisierte Hülle ist im Allgemeinen subhorizontal und die
Mineralisierung ist in einem Erzgang-Stockwork enthalten. Die Uranmineralisierung kommt sowohl in
der partiell verwitterten Zone als auch in frischem Gestein vor. In der südlichen Erweiterung
variiert die Deckschicht aus dem Känozoikum zwischen einem und zwölf Metern.
