Highlights
* Recent drilling has discovered a new gold zone at the Chui Prospect.
* The Chui Prospect, located approximately 1 kilometre along strike from the
Dalafuma Prospect, is open at depth and extends over a length of 900m.
* Drilling has confirmed high-grade mineralisation continuity at the newly
discovered Dalafuma Prospect; it extends over a length of 300 metres and is
open at depth.
* The Company plans follow up drilling on the Dalafuma and Chui Prospects as
soon as possible.
Bright Star Resources Limited (BrightStar) is pleased to announce that recent
drilling results indicate a strong potential to increase the current 520,000
ounce gold resource on the Miyabi Gold Project.
The potential for additional resources comes from both the newly discovered zone
of gold mineralisation at the Chui Prospect and the recently discovered zone of
gold mineralisation at Dalafuma which are located to the south of the known gold
resources.
BrightStar's Managing Director, Mike McKevitt said "These are extremely
encouraging results and support our belief that Miyabi has much more to reveal."
MIYABI GOLD PROJECT - BACKGROUND
The Miyabi Gold Project is located approximately 200 kilometres southwest of the
city of Mwanza in the Lake Victoria Goldfields, Tanzania. The property has
Mineral Resources contained in several deposits totalling 12.4 million tonnes at
1.3 g/t gold. This Resource comprises 520,000 ounces of gold (at a 0.5g/t cut-
off), estimated in accordance with JORC (2004). The resource comprises 370,000
ounces of Indicated Mineral Resource and 150,000 ounces of Inferred Mineral
Resource and was estimated in 2006.
In April 2011, BrightStar entered into a joint venture with African Eagle
Resources plc where BrightStar may earn a 75% interest in the Project by sole
funding exploration to completion of a bankable feasibility study.
Six of the seven individual gold resources estimated to date occur in an en-
echelon pattern of shear zones within a major structural corridor that cuts
across the northwest corner of the Miyabi greenstone belt. This major structural
corridor is named the Miyabi Structural Corridor (MSC), it trends northeast to
southwest extending for a length of 7.7 kilometres through the Miyabi property
and is some 800 to 1,000 metres wide.
The existing gold resources within the MSC extend along a strike length of
approximately 3.5 kilometres in the south western half of the structure and are
clustered over a width of approximately 500 metres from the centre of the
structure towards its northern boundary. Gold mineralization is hosted by
sheared, silicified and sulphide bearing mafic schists of possible meta-
sedimentary origin. The whole area of the MSC is totally obscured by soil cover
and a sub-surface laterite layer.
Previous drilling by African Eagle focused mainly on the area containing the
current gold resources and immediate strike extensions. Consequently, large
areas of the highly prospective MSC remain to be effectively drilled and this
became the prime focus of BrightStar's exploration program in 2012.
The potential for new zones of gold mineralization within the MSC, but outside
the area of current resources, was clearly demonstrated with the discovery of
the Dalafuma Prospect in June 2012. RC drilling under a RAB drill hole, which
intersected 21 metres @ 6.7g/t gold from 21 metres (announced in December
2011), confirmed the high grade gold mineralisation extended to depth and along
strike.
MIYABI RC AND AIRCORE DRILLING PROGRAM 2012
The recently completed RC and Aircore drilling program largely focused on the
new Dalafuma Prospect and other targets within the MSC. Between 29 May 2012 and
31 July 2012 a total of 54 RC holes for 4,971 metres and 52 Aircore holes for
2,138 metres were drilled.
The drilling program achieved two notable successes:
* A new 900 metre long zone of gold mineralisation was discovered
approximately 1 kilometre along strike from Dalafuma and named the Chui
Prospect. While drilling at Chui is presently limited, one significant high
grade intersection has already been obtained.
* A 300 metre long mineralised zone with several very significant high-grade
gold intersections was confirmed on the Dalafuma Prospect.
Drilling Results on Chui Prospect
The new Chui Prospect is located approximately 1 kilometre along strike to the
southwest from the Dalafuma Prospect and some 300 to 500 metres to the south of
the gold resources.
Two traverses of Aircore drilling (19 holes) and two traverses of RC drilling (4
holes) on a total of four sections at 200 metre intervals have discovered a new
zone of gold mineralisation which extends in a northeast to southwest direction
for some 900 metres. The zone appears to dip steeply to the northwest.
The two traverses of RC holes, drilled 400 metres apart both intersected gold
mineralisation as follows:
Section 401400E
11m @ 23.0g/t Au from 54m depth
Hole MBRC378
(including 5m @ 47.8g/t Au from 60m)
Section 401000E
3m @ 1.1g/t Au from 27m depth; and
Hole MBRC363
6m @ 2.1g/t Au from 33m depth.
Note: True width is interpreted to be approximately 70% of down-hole width.
All assays are of the 3 metre composited sample derived from 1 metre sampling
intervals. Full details of assays are listed in Annexure A.
The high grade intersection in Hole MBRC378 was at the bottom of the hole with
the last two samples assaying 61g/t and 27.9g/t gold respectively.
The two traverses of Aircore drilling on Sections 400800E and 401200E both
intersected the new mineralised zone. Hole MBAC206 on Section 400800E
intersected 15m @ 0.23g/t gold and Hole MBAC213 on Section 401200E intersected
12m @ 0.55g/t gold. Despite relatively low values, the Aircore drill hole
intersections confirm the continuity of the new Chui mineralised zone over a
strike length of some 900 metres.
The discovery of high grade gold mineralisation in the Chui zone in an area
(that was previously considered not prospective) is very encouraging. A two-
pronged follow up drilling program will be planned. Phase 1 will involve, step-
out RC drilling around and below the recent high grade intersection in Hole
MBRC378, infill drilling to confirm continuity of the zone and possible strike
extensions. Phase 2 will involve additional Aircore and RC drilling to test for
further new zones of gold mineralisation in this poorly explored area of the
MSC.
Drilling Results on Dalafuma Prospect
A total of 38 RC holes for a total of 3,813 metres have now been completed on
the Dalafuma Prospect on nominal 50 metre spaced sections. The drilling has
defined a 300 metre long zone of continuous gold mineralization with several
very significant high grade and relatively wide gold intersections.
Best gold intersections at a 1.0g/t gold cut-off are:
* Hole MBRC331 18m @ 18.3g/t Au from 45m depth
* (including 6m @ 39.9g/t Au from 48m depth);
* Hole MBRC349 12m @ 21.6g/t Au from 66m depth
* (including 9m @ 28.4g/t Au from 69m)
* 6m@ 4.1g/t Au from 99m; and
* Hole MBRC382 24m @ 10.6g/t Au from 21m depth
* (including 18m @ 13.5g/t Au from 24m).
Note: Results of Holes have previously been announced. True width is interpreted
to be approximately 70% of down-hole width. All assays are of the 3 metre
composited sample derived from 1 metre sampling intervals. Full details of
assays are listed in Annexure B.
All the above intersections are particularly robust with multiple 3 metre
samples above 10g/t. In fact 10 of the 18 samples above 1.0g/t gold (from the
above intersections) are above 10g/t gold and 6 of these are above 20g/t. The
highest individual 3 metre sample is 41.2g/t gold.
The Dalafuma mineralised zone strikes approximately northeast to southwest and
appears to be dipping steeply to the northwest. It varies in true width between
approximately 4 metres to 20 metres and is presently open at depth beneath the
current RC holes along its full 300 metre strike length. While geological
controls on the high grade mineralisation are not yet fully understood, the
prospect has grades considered high enough, that with additional economic
considerations, have the potential to support an underground mining operation.
