ASX RELEASE 21 January 2009
LUCKY BAY DELIVERS MORE high-grade gold
gold MINERALISATION confirmed AT Lucky bay north ? further drilling commencing next week
v Further high-grade intercept from the last Diamond drill hole completed at Lucky Bay prior to Christmas:
? 3 metres at 15.91 g/t gold
v Confirms down-dip extensions of high-grade mineralisation intersected pre-Christmas:
? 5 metres at 25.93 g/t gold, and
? 16 metres at 4.64 g/t gold on section 20820mN
v First-pass drilling at Lucky Bay North prospect confirms primary gold mineralisation with best intercepts of:
? 2 metres at 3.88 g/t gold, and
? 2 metres at 3.06 g/t gold
v Results confirm Integra?s geological model, upgrading other regional targets.
Integra Mining Limited (ASX: IGR ? ?Integra?) is pleased to report further high-grade gold results from the initial drilling program at the Lucky Bay prospect, part of the Company?s 100%-owned Aldiss-Randalls Gold Project near Kalgoorlie in Western Australia (Figure 1).
Results have been received for the last Diamond drill hole completed at Lucky Bay prior to the Christmas break (see Table 1 and Figure 2). Lucky Bay is located some 4.5 kilometres south of the recently discovered Salt Creek gold deposit (4.6Mt at 2.7 g/t for 400,000 contained ounces ? see ASX release 21 July 2008) and is the current focus of Integra?s exploration efforts.
Results from drill hole LBD006 confirmed the down-dip extension of gold mineralisation, returning an intersection of 3 metres grading 15.91 g/t gold from 96 metres (Figure 3). Gold mineralisation remains open down-dip and along strike to the southeast with additional extensional Diamond drilling expected to commence next week.
First-pass RC and Diamond drilling at the Lucky Bay North prospect has returned preliminary gold mineralised intercepts of:
? 2 metres at 3.06 g/t gold from 45 metres in LBRC019,
? 2 metres at 3.88 g/t gold from 76 metres in LBRC023D, and
? 1 metre at 1.47 g/t gold and 1 metre at 1.37 g/t gold from 92 metres and 110 metres respectively from LBRC26D.
These intercepts are considered highly encouraging first-pass results in that they further confirm Integra?s gold mineralisation model for Lucky Bay and Lucky Bay North. Both prospects remain open down-dip and along strike while a number of separate additional drill targets in the area are now considered highly prospective and will require first-pass drill testing in the near future.
Gold mineralisation at Lucky Bay and Lucky Bay North is hosted in pervasively silica/albite altered and pyrite/pyrrhotite mineralised fine-grained sediments with quartz carbonate sulphide veining.
Additionally, an 8 kilometre corridor between the Salt Creek gold deposit and the Lucky Bay prospect hosts a number of gold anomalies defined by very broad-spaced reconnaissance aircore drilling, none of which have yet been tested by RC drilling. These anomalies offer further potential for additional gold discoveries.
?Lucky Bay is continuing to deliver with the latest results further enhancing our understanding of the potential of this area and its potential to deliver significant additions to our existing resource inventory of 1.8 million ounces,? said Integra?s Managing Director, Chris Cairns.
In Summary:
v Consolidated Mineral Resources at the Aldiss-Randalls Gold Project of 1.8 million ounces at an average grade of 2.8 g/t gold with 72% of resource ounces in the Indicated Resources category (see ASX release 21 July 2008);
v A significant ?grassroots? gold discovery at Salt Creek located within a new 8 kilometre long gold trend only 60km east of Kalgoorlie;
v High-grade resources at the adjacent Randalls Project with Maxwells and Cock-eyed Bob deposits grading 5.2 g/t and 5.9 g/t gold respectively (see ASX release 21 July 2008);
v A 100% owned gold processing facility recently dismantled and ready for refurbishment and installation at the Salt Creek site;
v A pre-feasibility study completed displaying robust project returns with an IRR of 41% (see ASX release 14 August 2008); and
v Open pit production grade expected to be 3.4 g/t gold ? believed to be the highest open pit production grade of any similar scale of development in Australia.
Yours sincerely,
Chris Cairns
Managing Director
