IRO Inter Rock Minerals Inc

Inter-Rock Minerals Inc. (TSX VENTURE: IRO) reported today its second quarter 2008 earnings. Inter-Rock had income of US$95,000 for the quarter, compared to income of $37,000 for the same period in 2007. Second quarter EBITDA increased to US$303,000 from US$272,000 in 2007.

MIN-AD

MIN-AD, Inc., Inter-Rock's industrial minerals subsidiary, had another successful quarter this year. MIN-AD's sales volume was 1.5% higher than in the second quarter of 2007 despite a decline of 5% in cattle-on-feed. The sales increase was attributable to increased dairy marketing efforts. Operating cost increases were offset by higher revenues.

Mineral Properties

Data interpretation of a gravity survey and an induced polarization ("IP") survey was completed for Inter-Rock's Stinagree Valley property. The IP survey detected a zone of highly anomalous IP response that is also associated with a gravity gradient. Testing of this feature, and other identified structural features, is planned by drilling with several fences of holes.

A soil sampling program is underway at the Sentinel property. A total of 230 samples were gathered on a 100 foot grid at both the northern section of the property and at the southern boundary of a previously outlined anomalous gold zone. A track drill program will be laid out on the basis of the sampling results.
