Integra Mining Limited (ASX:IGR) is pleased to report that recent RC drilling along the Santa trend has
further confirmed the potential for both an open pit as well as underground production for the Randalls Gold
Project. In addition diamond drilling at Cock-eyed Bob continues to deliver outstanding results.
Santa Area high-grade results include -
• 14 metres at 5.58 g/t gold, including
o 5 metres at 8.47 g/t gold
• 5 metres at 13.21 g/t gold
• 9 metres at 4.68 g/t gold
• 7 metres at 4.21 g/t gold
Cock-Eyed Bob high-grade results include -
• 3.25 metres at 25.10 g/t gold, including
o 1.65 metres at 47.00 g/t gold
Santa and Cock-eyed Bob are located 16km east and 13km east, respectively of the Randalls Gold
processing facility (Figure 1). Recent drill intercepts support previously announced results, (see ASX
announcement 22 March 2011) and continue to indicate that high-grade gold mineralisation within the BIFhosted
Santa Trend persists at depth with excellent potential for underground extraction and also persists
along strike with good potential for additional open-pit production. The high-grade BIF-hosted gold deposits
at Cock-eyed Bob, Santa and Maxwells continue to emerge as potential future sources of high-grade
underground and open pit material for the Randalls Gold Project (Figure 2). Pre-stripping at the Maxwells
open pit and stockpiling of Maxwells Ore commenced in the June Quarter in preparation for fully fledged
production from the Maxwells open pit in 2012.
Resource drilling designed to enable final modelling of the open pit mineralisation of the Anomaly C and Fly
Camp areas has been conducted over the lasted few months. The drilling has returned some excellent
shallow results, including 7 metres at 4.21 g/t gold from 4 metres and 2 metres at 6.66 g/t gold from 1
metre (Figure 3).
Deeper holes drilled through the main zone of BIF units and to the eastern side of the Santa deposit have
shown a strong presence of magnetite-rich BIF and returned excellent grades, including 14 metres at 5.58
g/t gold from 89 metres and 5 metres at 13.21 g/t gold from 105 metres (Figure 3).

The three diamond holes drilled at Cock-Eyed Bob to give additional confidence to the grade model where
drill information was lacking and assist with the underground design returned high grade results including
3.25 metres at 25.10 g/t gold (Figure 4).
It is anticipated that, subject to regulatory approvals, trial underground mining will commence in December
at the high-grade Cock-eyed Bob gold deposit. An agreement has been reached with a preferred
underground mining contractor. The Mining Proposal has been lodged with the Department of Mining and
Petroleum in preparation for a December start-up.
If the trial mining proves successful, underground mining will continue to the next level at Cock-eyed Bob
and underground development at the Santa gold deposit will commence. Upon completion of open pit
mining operations at the Maxwells gold deposit, underground development would commence from the
base of the open pit.
Subject to successful completion of the trial mining exercise, the objective is to progressively develop
underground operations at the Cock-eyed, Santa and Maxwells gold deposits to the extent that 50% of the
process facilities feed is provided by underground sources at an expected grade of 5-6 g/t gold. This will be
blended with open pit production ore and stockpiled ore to maintain a 3-4 g/t head grade presented to the
process facility. By supplementing the process facility with 50% of feed from underground sources, the life
of the remaining open pit Ore Reserve is effectively doubled. In this way, without any additional discovery,
Integra is targeting a 10-year mine life at the Randalls Gold Project.
Previous high-grade drilling results from the Santa, Maxwells and Cock-eyed Bob gold deposits were
released to the market on 9 November 2009, 22 January 2010, 8 February 2010, 10 June 2010, 24 August
2010, 10 September 2010 and 21 March 2011.
Yours sincerely,
