RECONNAISSANCE DRILLING AT THE ALDISS GOLD PROJECT IDENTIFIES IN LENGTH SEVERAL EXCITING NEW PROSPECTS IDENTIFIED BY AIRCORE DRILLING ABOUT TO BE TESTED BY RC DRILLING

Integra Mining Limited (ASX:IGR, Integra) is pleased to announce that follow-up reconnaissance aircore drilling at several prospects within the Aldiss Gold Project has returned encouraging results including:-

• 8 metres at 2.11 g/t gold in including 4 metres at 3.37 g/t gold in Zone B,
• 3 metres at 1.35 g/t gold in Zone B,
• 1 metre at 2.40 g/t gold in Zone B,
• 4 metres at 1.25 g/t gold in Zone C,
• 1 metre at 1.58 g/t gold in Zone C, and,
• 4 metres at 1.29 g/t gold in Zone N.
Previously released results included:
• 8 metres at 1.25 g/t gold in Zone A,
• 4 metres at 1.61 g/t gold in Zone C, and,
• 4 metres at 1.37 g/t gold in Zone C.

As wide-spaced reconnaissance aircore results, these anomalies are considered very significant.

The discovery of the Salt Creek gold deposit in the Randalls Gold Project was the result of following-up a best aircore drill result of 1 metre at 2.4 g/t gold.

The next best pre-discovery result at Salt Creek was 3 metres at 0.84 g/t gold. Typically in this type of reconnaissance programme, any result greater than 0.1 g/t gold would be considered anomalous.

Aircore reconnaissance drilling is not intended to define a gold deposit but only to indicate the general vicinity where one may be concealed.

A total of approximately 1,800 aircore holes have been drilled over the two year reconnaissance phase for
nearly 100,000 metres of drilling.

In general, three trends associated with folded and faulted dolerite intrusive complexes have been defined, referred to as the Admiral (6 kilometres), Batavia (6 kilometres) and Challenger (8 kilometres) trends hosting a large number of discrete anomalous zones.

Nine areas of broad gold anomalism, namely Zones A to F inclusive, Zone I, and Zone M to P inclusive, were selected for follow-up aircore drilling (Figure 2).
Zone B has returned +1g/t intercepts in holes on 5 consecutive drill lines over a strike of 600m (Figure 3),
with Zone N, occurring to the north within the same trend.

Zone C has returned +1g/t intercepts in holes on 3 consecutive drill lines over a strike of 400m, with consistent anomalism in a WNW / ESE orientation. The
Zone A anomalism is more dispersed, but highlights a zone of up to 3.5km in length.

Planning of RC followup is in progress with drilling to commence in late March.

The target area within the Aldiss Gold Project is located approximately 60 kilometres south east of the Randalls gold processing facility, and about 20 kilometres south of the Karonie Main Zone gold deposit (Figure 1).

The Aldiss Gold Project hosts a Mineral Resource of nearly 500,000 ounces in several gold deposits (Table 1, see ASX release 25th January 2011).

Integra is focussing a significant portion of its 21 February 2012 exploration efforts on the Aldiss Gold Project with the objective that, given the already substantial gold endowment of the project, a relatively modest additional discovery of economic mineralisation could be sufficient to justify the establishment of a stand-alone mining / milling operation in this area.

Investors are cautioned that mineral exploration is an uncertain business and may not result in an economic discovery.

In September 2010, Integra signed a farm-in agreement with Image Resources on two tenements along strike of the Aldiss Gold Project, increasing the ground position over the prospective corridor in the southeastern part of the project.

In 2008, Integra entered into a collaborative research project with the CSIRO to develop gold exploration targets in the Aldiss Gold Project. The project identified a 10 kilometre long major shear and fluid conduit active during the major gold event in the region which has had very sparse previous exploration.

During 2010, Integra drilled 1,194 reconnaissance aircore drill holes on very wide-spaced 320 metre lines with 80 metre spaced drill collars and followed-up with an additional 593 aircore drill holes in 2011.

The region has a very complex regolith with a stripped Archaean profile overlain by reworked Archaean sediments, Tertiary sediments, wind-blown sands, paleo-drainage channels and salt lakes.

In summary, the shallow cover is very complex and gold anomalism is not expected to be as widespread as in areas with well developed and stable weathering profiles.

As a result, the tenor of anomalism is expected to be lower and more constrained than in other areas of the Eastern Goldfields.

Consequently, as previously reported (see ASX release 18th January 2011), despite the very wide spacing of the reconnaissance aircore drilling, the number and tenor of anomalous gold results are considered particularly encouraging.

The geology within the target area consists of high-magnesium mafics, andesites, intermediate to felsic
volcanoclastics, archaean shales and banded cherts, granodiorite, syenites, porphyries and sediments.

Gold mineralisation appears to be hosted by intermediate volcanics and porphyritic basalt and is possibly
structurally related to fold hinges and/ or second order faults.
