Inter-Rock Reports Second Quarter Results

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.
