BrightStar's results continue to show that the Miyabi structural corridor is highly prospective and that systematic exploration will be likely to make significant additions to the 0.5 million ounce resource previously delineated by African Eagle.
BrightStar reports that many of the rotary air blast ("RAB") holes intersected broad zones of gold mineralisation in the granite/greenstone contact area, which was the main conceptual target of the RAB programme. The RAB holes were shallow, typically 25m-30m in depth, and reveal that much of the area is covered by a 10m thick blanket of barren laterite and ferricrete, which limits the effectiveness of soil geochemistry. Beneath this cover is a zone of weathered and leached bedrock several tens of metres thick, within which gold has been depleted. Hence, it is likely that higher grades could be present in the unweathered rock beneath the moderate gold grades seen in the leached zone by the RAB holes. Deeper reverse circulation ("RC") drilling has now commenced to test for higher grade mineralisation beneath the better RAB intersections.
The RAB drilling program commenced at Miyabi in June 2011 and comprised 445 holes for 12,013m. The majority of RAB holes tested the highly prospective granite/greenstone contact zone with shallow holes drilled at 30m spacing along fences 200m apart.
Results have now been received from around 80% of the RAB holes drilled; the remaining results and first results from the RC drilling are expected in early December 2011.
The Miyabi gold project is a Joint Venture between African Eagle and ASX-listed BrightStar Resources Ltd, under which BrightStar can earn up to 75% of the project by completing exploration and a feasibility study.
A table of all mineralised intersections is set out in the
appendix to this release and full details of the Miyabi
drilling programme and results can be found on

(eoh) indicates that the hole ended in gold mineralisation
- Most samples analysed as 3m composites
- Sampling carried out using a cyclone and riffle splitter at 1m intervals
- Sample preparation at ALS Global in Mwanza, Tanzania
- Gold analysis carried out by OMAC Laboratories in Ireland using 50g aqua regia
- QAQC samples submitted routinely with excellent results
- Holes located by GPS then transformed to local grid coordinates
- Intersections are generally interpreted to represent true width. Where holes ended in mineralisation, true thickness may be greater than the intersection thickness.
