Brinkley Mining - Projects
Overview
Brinkley Mining’s 49% owned associate company Western Uranium has as its primary asset, the Waterval prospect, in the Karoo region of South Africa. In addition Western Uranium has applied for prospecting rights over the Damsfontein/Bloemfontein, Rietkuil and Flagfontein areas. In total the Waterval, Damsfontein/Bloemfontein and Rietkuil areas are underlain by approximately 166 square kilometres of uraniferous sandstone.
According to the Competent Person Report (May 2006) prepared by SRK Consulting, these areas of known and potentially uraniferous sandstones can be interpreted as exploration potential in terms of the scale of mineralisation that is targeted by the Company in its exploration programme. It should be noted that the term “exploration potential” is meant to convey precisely that and is not a Mineral Resource classification of any kind, and particularly not under any of the modern standards such as the JORC Code, SAMREC, IMMM or CIM Standards.
SRK Consulting stated that based on the assumption that between 5% and 10% of the area underlain by uraniferous sandstone may be mineralised, and typical mineralisation grades for the individual prospects, the magnitude of the total in-situ mineralisation that the Company is targeting in its exploration is likely to fall within a range of 41 million and 83 million pounds of uranium oxide (“U3O8“) and between 23 million and 47 million pounds of molybdenum (“Mo”).

The mineralisation potential of the Flagfontein Prospect is not known well enough to allow this kind of estimate to be made. |

To date prospecting rights have been granted, notarised and effected for the entire area of the Waterval prospect and a 218 hectare portion of the Rietkuil prospect. The remaining prospecting rights have yet to be granted however Western Uranium continues to pursue clarification from the DME as to the status of the applications for these areas.
