OVERVIEW

Finance

• Group loss after tax for the three months ended 31 March 2011 of $3 million (unaudited) - includes discontinued operations.

• The sale of Paulsens to Northern Star, which completed in July 2010, was for a purchase consideration of up to A$40 million. The Group received the two top-up payments of A$2.5 million each during the quarter, bringing the total consideration up to the A$40 million maximum.

• Interest income during the quarter was $1,547,000.

• During the quarter 3,607,725 options to acquire shares in the Company were exercised.

• Cash balance and term deposits at quarter end totalled $181.088 million.

Operations

• At Tujuh Bukit the ongoing drilling results from the underlying porphyry copper-gold-molybdenum mineralisation are particularly encouraging and there is an emerging picture of a very large porphyry system with zones of particularly high grades and elevated gold-copper ratios.

Tujuh Bukit Oxide

• On 2 February 2011, the Company announced that the technical report entitled "Tujuh Bukit Project Report on Mineral Resources" dated January 2011, has been filed on SEDAR (www.sedar.com) as well as with the ASX (www.asx.com) (see the Company's news release of 14 December 2010 for a summary of the oxide resource update). The report was prepared by independent consultants Hellman and Schofield Pty. Ltd. in accordance with the JORC Code and Canadian NI 43-101. It details an updated Inferred Resource estimate of 130 million tonnes at 0.55 g/t gold and 18 g/t silver above a 0.2 g/t gold cut-off, for 2.4 million ounces of contained gold and 80 million ounces of contained silver within the combined oxide zones of the Tumpangpitu area of the Tujuh Bukit Project in Indonesia.

• On 20 April 2011, subsequent to the quarter end, the Company reported the results of a Preliminary Economic Assessment ("PEA"), independently prepared by Kappes Cassiday of Reno, Nevada, for a potential heap leach, open pit gold mine on the oxide resource of the Tumpangpitu area. Based on conservative assumptions, the PEA demonstrated a life of project annual average production of 143,000 recovered ounces of gold for 9 years at a cash cost of US$376 per ounce, net of silver credits at US$16.50 per ounce. The project delivers a post-tax cumulative cashflow of US$445 million, an NPV (at a 10% discount rate) of US$180 million and an IRR of 31%, at a gold price of US$1,050 per ounce. The Company's board has approved immediate progress towards commencement of a pre-feasibility study to be conducted in parallel with the advancement of the forestry approval process.

Tujuh Bukit Porphyry

• On 31 January 2011, the Company announced that drilling results for the copper-gold porphyry had identified extensions to the known mineralisation.

• On 3 March 2011, the Company reported that assay results received from five deep exploratory drill holes intercepted additional mineralisation adjacent to and south of the main Tumpangpitu porphyry Inferred Resource area. Together, diamond drill holes GTD 178, 181, 182, 183 and 184 confirm the clear potential for the expansion of the Tumpangpitu porphyry.

• An updated porphyry resource estimate is due in May which will incorporate further deep drilling around the main Tumpangpitu copper-gold porphyry zone. The initial resource, published in September 2010, contained 500 million tonnes at 0.4% copper and 0.5g/t gold.

FORESTRY ACTIVITIES

The Indonesian Forestry Law restricts non forestry activities within protection forests and prohibits mining using an open pit method in protection forest areas. Accordingly, Intrepid's Alliance partner, PT IMN, is working with relevant Indonesian authorities regarding a potential review of forest land status. While similar reviews have led to the granting of reclassifications, there is no assurance that the forestry reclassification will take place in this instance.
