re: Ann: High-grade Gold to 139 g/t from Salt... HIGH-GRADE GOLD TO 139 G/T GOLD FROM
SALT CREEK DIAMOND DRILLING
GRADES UP TO 139g/t Au FROM ONGOING DIAMOND DRILLING.
􀂙 Further high-grade intercepts received from diamond drilling at the Salt Creek gold
deposit (Randalls Gold Project):
􀂾 40.5 metres at 6.48 g/t gold including
􀂙 4 metres at 12.82 g/t gold,
􀂙 0.7 metres at 139 g/t gold, and
􀂙 0.8 metres at 16.07 g/t gold.
􀂾 15.5 metres at 4.51 g/t gold including
􀂙 3 metres at 18.41 g/t gold.
􀂾 38 metres at 2.99 g/t gold including
􀂙 2 metres at 13.04 g/t gold, and
􀂙 1 metre at 14.40 g/t gold.
􀂙 Significant visible gold noted from ongoing diamond drilling.
􀂙 Exploration being stepped up at Randalls Project with five rigs currently on site.
Integra Mining Limited (ASX: IGR ¨C ¡°Integra¡±) is pleased to report further high-grade gold
results from diamond drilling at the Salt Creek gold deposit, part of the Company¡¯s 100%-owned
Aldiss-Randalls Gold Project near Kalgoorlie in Western Australia.
Three diamond drill holes have been completed on section 25,200mN as part of the current
confirmation diamond drilling programme designed to increase confidence in the volumes, grade and
structural / lithologic controls on gold mineralisation. An additional objective is to increase the
proportion of diamond drilling relative to RC drilling and to ¡®twin¡¯ some previous RC drill holes with
diamond drill holes to assess if there is a material difference in widths or grades of intercepts
between the two drilling methods.
In this regard, hole SKD021 (41 metres at 6.48 g/t gold) was a diamond drill twin of RC drill hole
SKRC023 (36 metres at 3.47 g/t gold). This hole displayed approximately 200% more gold on a
gram*metre basis compared to the original RC drill hole. Conversely, ¡®scissor¡¯ drill hole SKD019
intercepted 13 metres at 2.24 g/t gold and may have resulted in a minor gold mineralised volume
reduction.
While Integra¡¯s geological team expects the confirmation drilling to demonstrate both gains and
reductions in volume and/or grade on a hole by hole basis, the Company expects the drilling to
result in an overall increase in confidence in the resource with no other material change.
An intensive review of the geology and structure within the Salt Creek gold deposit undertaken as
part of the Feasibility Study has highlighted the potential for high-grade, east dipping, structurally
controlled gold mineralisation related to abundant quartz veining, including occasional visible gold
and associated alteration.

ASX RELEASE 25th May 2009
Near-mine exploration drilling is planned to confirm and trace this high-grade structure into
additional lithologies which are considered to be favourable hosts to well-developed gold
mineralisation. Within the stratigraphic sequence beneath the Salt Creek differentiated dolerite sill ¨C
host to the bulk of currently known gold mineralisation, there is a second differentiated dolerite sill ¨C
the ¡®Big Sill¡¯ ¨C and a highly sulphidic inter-flow sedimentary horizon, both of which are considered
potential hosts for additional gold mineralisation.
Exploration
Exploration activities are currently being stepped up within the Randalls Gold Project to evaluate new
target areas and test the potential for a significant new discovery in parallel with the ongoing
Feasibility Study. Three diamond rigs, one RC rig and one aircore rig are currently on-site and an
additional diamond drill rig is contemplated.
Diamond drilling is on-going northwest of the Lucky Bay prospect.
Feasibility Study
As per previous advice to the market, the Randalls Project Feasibility Study remains on target for
completion in June / early July.
In Summary:
􀂙 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);
􀂙 A significant ¡®grassroots¡¯ gold discovery at Salt Creek located within a new 8
kilometre long gold trend only 60km east of Kalgoorlie;
􀂙 High-grade resources at the adjacent Randalls Project with Maxwells and Cockeyed
Bob deposits grading 5.2 g/t and 5.9 g/t gold respectively (see ASX release
21 July 2008);
􀂙 A 100% owned gold processing facility recently dismantled and ready for
refurbishment and installation at the Salt Creek site;
􀂙 A Pre-feasibility Study completed displaying robust project returns with an IRR of
41% (see ASX release 14 August 2008) and a Feasibility Study for the Randalls
Gold Project is in-progress;
􀂙 Open pit production grade expected to be the highest open pit production grade of
any similar scale of development in Australia.
