Inter-Rock Reports Third Quarter Results

Inter-Rock Minerals Inc. (TSX VENTURE:IRO) reported today its third quarter 2008
earnings. Inter-Rock had no income or loss for the quarter, compared to income
of $118,000 for the same period in 2007. Third quarter EBITDA decreased to
US$174,000 from US$377,000 in 2007.


MIN-AD

MIN-AD, Inc., Inter-Rock's industrial minerals subsidiary, reported a decrease
in sales volume of 7%. The decline was exclusively due to fewer cattle-on-feed
in Texas and Kansas which was a consequence of exceptionally high feed
ingredient costs. Sales volumes in all other regions either increased or were
steady. Volumes have increased in the fourth quarter due to a seasonal increase
in feedlot populations and declining feed costs.


Mineral Properties

A drilling permit application has been submitted for a first phase of drilling
at Inter-Rock's Stinagree Valley property. The primary purpose of phase one will
be to test observed geophysical anomalies in order to assist with the
development of a geological model.


The soil sampling program has been completed 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. Assay results have been received and a compilation of results is
expected by early December.
