Denison Project (EL 27181) - Northern Territory (100% CUU)
The Denison Project lies some 250kms north-west of Alice Springs in the Northern Territory. The Project contains known primary uranium mineralisation related to granitic intrusives and altered country rocksand is prospective for primary granitic uranium deposits. There are numerous examples of this type of mineralisation including the Rossing Style (Rossing, Rossing South and Etango deposits in Namibia). The importance of these deposits is not accurately reflected in global reserves because much of the mineralisation has only recently been discovered (ie. Extract Resources’ Rossing South) and potential end members of this type of mineralisation are often classified as other types (including Olympic Dam).
Rossing South for example has three zones of mineralisation recognised to date and the first two have a current resource estimate totalling 270 million pounds U3O8. (EXT ASX announcement 22/7/09) They are massive targets which have received little attention in Australia and other parts of the world to date.
Callabonna’s first pass program returned uranium oxide results of between 268ppm and 979 ppm U3O8 from both altered and unaltered granitic gneisses of the Proterozoic age Wangala Granite. Several samples also contained elevated Rare Earth Elements (REEs). These results suggest there is potential for primary uranium mineralisation hosted within the Proterozoic aged granites of the area.
In May 2010 Callabonna was awarded a collaborative drill funding grant under the Northern Territory Government’s “Bringing Forward Discovery” initiative. Callabonna was awarded $52,500 through the “Geophysics and Drilling Collaborations” program for the drilling of two diamond tail drillholes on the Denison Uranium project testing for uranium mineralisation associated with highly differentiated granites.
Exploration Strategy
- Detailed mapping and ground radiometrics
- Partial extraction soil sampling to define covered areas of minerlisation for drill targeting
- Reverse Circulation (RC) and diamond drilling
