Inter-Rock RNY Mineral Property Update

TORONTO, ONTARIO--(Marketwire - Jan. 27, 2011) - Inter-Rock Minerals Inc. (TSX VENTURE:IRO) ("Inter-Rock") announces results from an exploration drilling program at its wholly-owned RNY Project in Humboldt County, Nevada. The RNY Project is located in Humboldt County, approximately 80 miles north of Winnemucca, Nevada. Inter-Rock holds 22 claims covering 440 acres. No royalties or lease payments are associated with the property.

The drill program comprised 8 reverse circulation drill holes totalling 1,070 feet (326 m.). All the holes were duplicate-sampled on 5' intervals, with the samples analyzed by BSI Inspectorate in Sparks, NV, an ISO 9001:2008 certified laboratory. Each of the holes returned contiguous intervals greater than 0.001 oz Au/ton. Gold mineralization is present both in Permian Happy Creek metasediments and in Cretaceous granodiorite.

Holes 10-05 and 10-06 were the most significantly mineralized. A continuous 35' interval in hole 10-05 averaged 0.008 oz Au/ton at 20-55' from surface (including 0.044 from 30-35'). Hole 10-06 contained a continuous 45' interval from 20 to 65' averaging 0.006 oz Au/ton and included 0.022 oz Au/ton (from 40-45') and 0.019 oz Au/ton (from 55-60') intercepts. Holes 10-02 and 10-04 bottomed in 0.003 and 0.001 oz Au/ton respectively, leaving the mineralized zones open at depth.

The drilling generally shows an association of anomalous Au with elevated As and fluffy Fe oxide in the host rocks, as well as with fracturing and bleaching of the host rocks. Clay and sericite alteration are also commonly associated with the Au. Hg is generally low, as are Ag and base metals, although a nearby area is highly anomalous in Hg without Au.

The present drilling explores only a small portion of the area of the property hosting anomalous gold. The best surface assay from another part of the property that was not drilled was a 15' trench sample averaging 0.205 oz Au/ton.

Inter-Rock considers these and previous results sufficiently encouraging to warrant further exploration of the property. Planning is underway for the next phase of work.

To date, there has been insufficient exploration at RNY to define a mineral resource and Inter-Rock cautions that there is a risk that further exploration will not result in the delineation of a resource.
