TORONTO, ONTARIO--(CCNMatthews - March 28, 2007) - Intrepid Mines Limited (TSX:IAU) (TSX:IXN) (ASX:IAU), an international gold and silver production, development and exploration company, is pleased to announce the commencement of a post-feasibility core drilling program at its 100% owned Casposo project in San Juan Province, Argentina.
The 3,000 metre drilling program will be conducted at the Kamila Inca Vein and the Kamila Southeast Extension (SEXT) to vertical depths of up to 300 metres (see attached Longitudinal Section). This is the first drill program since the completion of the Casposo Feasibility Study. The near term goal for exploration at Casposo is to increase the life of mine proposed in the Feasibility Study by testing deep pit and underground vein targets.
Recent drilling at Kamila and Kamila SEXT zones has returned encouraging values ranging to highs of 22.9 grams per tonne gold and 1,795 grams per tonne silver over 4.0 metres (Kamila Inca) and 3.40 grams per tonne gold and 1,192 grams per tonne silver over 3.0 metres (SEXT).
These results and others noted below are not included in the current resource and reserve estimate (see press release dated March 5, 2007).

Laurence Curtis, President and Chief Executive Officer said, "Drilling at Casposo continues to expand the project. The Inca vein extension and the Kamila Southeast Extension are revealing significant potential to expand the current reserve estimates and mine life of the project."
Kamila Inca Vein
New drilling will initially focus on the Inca and B-veins of the Kamila deposit. Drilling in 2006 continued after the cut-off date for completion of the Kamila resource and reserve estimations. This consisted mainly of step-out holes on the Inca Vein which have now tested this mineralized structure to the east of a north-south trending dyke which transects the Kamila deposit. New work in this area will increase the drilling density to allow the area to be evaluated for additional resources at Kamila as well as to continue testing extensions of this mineralization to the southeast.
Kamila Southeast Extension (SEXT)
New drilling will also be focused on the Kamila Southeast Extension zone (SEXT). The Kamila SEXT was discovered in February 2006 by exploration hole CA-06-152 (brecciated quartz vein assaying 4.51 grams per tonne gold and 2,274 grams per tonne silver over 1.60 metres at a depth of 90 metres). This zone represents a new advanced, underground exploration target for Intrepid at the Casposo Project and validation of the Pajingo deposit exploration model being used to explore the Kamila deposit.
