TUJUH BUKIT SULPHIDE COPPER-GOLD PROJECT AGREEMENT EXTENDED TO 15 DECEMBER 2009

BRISBANE, AUSTRALIA--(Marketwire - Sept. 30, 2009) - Intrepid Mines Limited (TSX:IAU)(ASX:IAU) ("Intrepid" or the "Company") wishes to announce that, following the signing in July 2009 of a Heads of Agreement ("HOA") with Vale Exploration Pty Ltd, a wholly-owned subsidiary of Vale S.A (NYSE:VALE) ("Vale"), granting Vale an option to acquire rights to Intrepid's Tujuh Bukit sulphide copper-gold project in Indonesia (see Intrepid news release of 10 July 2009), the deadline for the completion of all formal and binding documentation has been extended to 15 December 2009. The HOA specifies the general commercial terms that have been agreed between the parties, and is at this time non-binding. Under these terms, Vale, the world's second largest mining company, could earn a 60% shareholding in a joint venture company holding the rights to the Tujuh Bukit project by, amongst other terms, spending a total of US$40 million. Intrepid and its Indonesian alliance partner, PT Indo Multi Niaga ("PT IMN") would retain the remaining 40% interest in the sulphide copper-gold project, and will be free carried by Vale through to completion of a bankable feasibility study.

As previously announced, Intrepid retains 80% of the significant, near-surface, gold-silver oxide cap.

ABOUT TUJUH BUKIT

Tujuh Bukit is located in the province of East Java, Indonesia and covers an area of approximately 11,600 hectares, about 205 kilometres southeast of Surabaya, the provincial capital. The project site has a potentially large porphyry and high sulphidation epithermal gold-silver-copper system, which is underneath a significant, near-surface, gold-silver oxide cap.

Preliminary exploration, including diamond drilling on two (Zones A&C) of multiple zones being examined around the oxide deposit, has determined a National Instrument 43-101-compliant aggregate Inferred oxide resource of 2.57 million ounces gold equivalent (gold + silver) grading approximately 1 grams per tonne (g/t) at 0.5g/t gold equivalent cut off (see Intrepid news releases dated 27 July 2008 and 17 December 2008). Additional drilling on Zones B and B South have also encountered encouraging mineralisation, confirming additional gold-silver potential (see Intrepid news release dated 2 March 2009).

Deeper drilling below the oxidized zone of the project intersected extremely encouraging assays from a related but separate porphyry copper-gold zone, including one hole, GTD 08-35, that intercepted 627 metres of 0.45 g/t gold and 0.44% copper (see Intrepid news release dated 17 July 2008).

FORWARD-LOOKING STATEMENTS

This announcement contains certain forward-looking statements, relating to, but not limited to Intrepid's expectations, intentions, plans and beliefs. Forward-looking information can often be identified by forward-looking words such as 'anticipate', 'believe', 'expect', 'goal', 'plan', 'intend', 'estimate', 'may' and 'will' or similar words suggesting future outcomes, or other expectations, beliefs, plans, objectives, assumptions, intentions or statements about future outcomes, or statements about future events or performance. Forward-looking information may include reserve and resource estimates, estimates of future production, unit costs, costs of capital projects, and timing of commencement of operations and is based on current expectations that involve a number of business risks and uncertainties. Factors that could cause actual results to differ materially from any forward-looking statement include, but are not limited to, failure to establish estimated resources and reserves, the grade and recovery of ore which is mined varying from estimates, capital and operating costs varying significantly from estimates, delays in obtaining or failures to obtain required governmental, environmental or other project approvals, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects and other factors. Forward-looking statements are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual events or results to differ materially from those expressed or implied.

Shareholders and potential investors are cautioned not to place undue reliance on forward-looking information. By its nature, forward-looking information involves numerous assumptions, inherent risks and uncertainties, both general and specific, that contribute to the possibility that the predictions, forecasts, projections and various future events will not occur. Intrepid undertakes no obligation to update publicly or otherwise revise any forward-looking information whether as a result of new information, future events or other such factors which affect this information, except as required by law.

Statements relating to gold resource estimates are expressions of judgment, based on knowledge and experience and may require revision based on actual production experience. Such estimates are necessarily imprecise and depend to some extent on statistical inferences and other assumptions, such as gold prices, cut-off grades and operating costs, which may prove to be inaccurate. The drill programme at Tujuh Bukit is insufficiently advanced to define a resource estimate and it is uncertain if further drilling will result in the determination of a resource statement at the project.

QUALIFIED PERSON

The information in this announcement that relates to exploration results is based on information compiled by or under the supervision of Malcolm Norris, who is a full-time employee of Intrepid Mines Limited. Mr Norris has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" and a Qualified Person as defined in the Canadian National Instrument 43-101 (standards of Disclosure for Mineral Projects). Mr Norris consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.

The information in this announcement that relates to mineral resources is based on information compiled by or under the supervision of Dr. Phillip Hellman, who is an independent consultant to Intrepid Mines Limited and a Director of Hellman & Schofield Pty Ltd. Dr Hellman has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as an Independent Competent Person as defined in the 2004 Edition of the "Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves" and an Independent Qualified Person as defined in the Canadian National Instrument 43-101 (standards of Disclosure for Mineral Projects). Dr Hellman consents to the inclusion in the report of the matters based on his information in the form and context in which it appears. Dr Hellman has undertaken independent verification sampling and assaying of drill core with a close agreement of results with those previously reported. A 40 x 40 x 6 metre block model was used for the quoted estimates. If smaller selective mining units are considered it is estimated that an approximate 10 to 20% lift in grade may result. In future, increasing the drilling density in areas of higher gold grades is anticipated to achieve a higher grade outcome.

SAMPLE ANALYSIS

Intrepid exercises a strict chain of sample custody in its drilling program at Tujuh Bukit. Joint Venture personnel remove core from the drill rig and deliver it to a project geologist who logs the core and marks the core into two metre sample intervals. Intrepid and Joint Venture personnel supervise the immediate splitting, sawing and bagging of samples, and packaging of groups of samples for dispatch to the laboratory. The remainder of the split core remains on site.

Samples are securely packaged, batched, and then transported under supervision to Intertek's laboratory facility in Jakarta. At the laboratory, the samples are prepared by crushing and pulverizing and a 30 gram charge is assayed for gold by conventional fire assay and/or atomic absorption methods. Multi-element ICP analysis is carried out using a multi-acid digestion process. All samples that contain silver and/or copper, lead, and zinc values that exceed the upper detection limits for ICP are re-analysed by conventional atomic absorption methods to determine the absolute values of these metals.

GOLD EQUIVALENTS

The gold equivalent ratio for silver has been set at 65:1 based on US$650/oz gold (Au) and US$10/oz silver (Ag.) Historical bottle roll tests have shown recoveries of 83% Au and 84.5% Ag, supporting a 65:1 ratio. Recently received CIL metallurgical testing results from Zone C achieved recoveries of approximately 90% for both Au and Ag at a grind of 80% passing 75 um. Comparable recoveries for both gold and silver in the recent tests from 4 composite samples from Zone C oxide material also support the 65:1 gold equivalence ratio.
