ASX RELEASE 21st July 2008
75% OF 400,000oz SALT CREEK DEPOSIT
RE-CLASSIFIED AS INDICATED RESOURCES
Indicated Resource component increased more than threefold following successful risk-based
statistical analysis of the recently upgraded Salt Creek Mineral Resource, resulting in:
Indicated Resources of 3.4Mt at 2.8 g/t gold for 300,000 contained ounces.
Inferred Resources of 1.3Mt at 2.6 g/t gold for 100,000 contained ounces.
75% of the Salt Creek Mineral Resource now available for conversion to Ore Reserves
subject to normal economic parameters.
Modest additional drilling planned to upgrade the Inferred Resource component to
Indicated status.
Integra is uniquely placed with:
Consolidated Mineral Resources at the Aldiss-Randalls Gold Project of 1.8 million ounces at
2.7 g/t gold (see ASX release 26 June 2008).
A significant ¡®grassroots¡¯ gold discovery at Salt Creek, located 60km east of Kalgoorlie.
High-grade resources at the adjacent Randalls Project with the Maxwells and Cock-eyed
Bob deposits grading 5.2 g/t and 5.9 g/t gold respectively (see Table 2).
A 100% owned gold processing facility recently dismantled and ready for refurbishment
and installation at the Salt Creek site.
A pre-feasibility study to be completed near the end of July.
An open pit production grade expected to be +3 g/t gold.
Integra Mining Limited (ASX: IGR ¨C ¡°Integra¡±) is pleased to report that statistical simulations of the gold grade
variance for the recently announced mineral resources upgrade for the Salt Creek gold deposit in the Company¡¯s
Aldiss-Randalls Project to 4.6 million tonnes at 2.7 g/t gold for 400,000 contained ounces has resulted in the
re-classification of a significant proportion of the resource to the Indicated Resources category.
The new classification for Salt Creek includes 3.4Mt at 2.8 g/t gold for 300,000 contained ounces as Indicated
Resources available for conversion to Ore Reserves subject to normal economic parameters. This reclassification has
resulted in a more than threefold increase in the Indicated Resources within the Salt Creek gold deposit.
Integra¡¯s total consolidated Mineral Resource at the Aldiss-Randalls Project (including the Salt Creek gold deposit) is
20Mt at 2.7 g/t gold for 1.8 million contained ounces of which some 72% or 1.3 million ounces are now in the
Indicated Resources classification (see Table 2).
The conversion of Indicated and Measured Resources to Ore Reserves is subject to Modifying Factors such as mining
dilution, open pit strip ratio, mining and milling costs, metallurgical recoveries and other economic parameters.
Investors are referred to the JORC Code, especially Clause 28 for further information on Modifying Factors as they
relate to conversion of Mineral Resources to Ore Reserves.
The remaining Inferred Resources at the Salt Creek gold deposit are primarily contained within two ¡®wireframed¡¯
zones of mineralisation at the southern end of the deposit and a modest additional RC drilling programme is being
planned to increase confidence in gold grade variance in these areas with the intention of further re-classification to
Indicated Resources.

Table 2 Note: All deposit figures are reported as calculated from their relevant resource block models. Sub-totals, project totals and the Integra
Mining Limited total resource figures are rounded to 2 significant digits as defined by Clause 26 in the 2004 Edition of the ¡°Australasian Code for
Reporting of Exploration Results, Mineral Resources and Ore Reserves¡±. All sub-totals, project totals and the Integra Mining Limited total resource
figures are calculated from the raw deposit figures then rounded to 2 significant digits. Totals are not calculated from intermediate sub-total which
results in rounding variances which may be observed between the various total figures.
