Inter-Rock Nevada Mineral Property Update

TORONTO, ONTARIO--(Marketwire - Oct. 12, 2010) -

RNY Project

Inter-Rock Minerals Inc. (TSX VENTURE:IRO) ("Inter-Rock") announces commencement of work on the first phase of a track-mounted reverse circulation drill program at its wholly-owned RNY Gold Project in Nevada (previously referred to as Sentinel Peak). The Project recently received approval by the US Bureau of Land Management for an exploration program under a Notice of Operations. 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.

Road work to provide drill access to the project area has been completed by Inter-Rock. Channel (10' to 15') sampling of bedrock exposures in the recent road cuts yielded the following new results.

  • Area 1: 
    125' of anomalous Au values (>30 ppb).
    15' continuous sample @ 0.015 oz/t (not included in above).

  • Area 2: 
    100' of anomalous Au values (>30 ppb).

  • Area 3: 
    45' of anomalous Au values (>30 ppb).
    20' continuous sample @ 0.018 oz/t (not included in above).
    3' @ 0.162 oz/t, adjacent to above.
    3' vertical sample @ 0.036 oz/t, adjacent to above.

All of the areas sampled were well oxidized with strong fracturing and iron oxide staining.

All analyses were performed by BSI-Inspectorate located in Sparks, NV. The analyses were performed using fire assaying with AA finish for Au, cold vapor/AA for Hg, and aqua regia digestion followed by AA analysis for Ag, As, Cu, Pb, Sb, and Zn.

The drill program is designed to test for high-angle structure-controlled epithermal gold mineralization as well as stratigraphically/structurally controlled disseminated gold mineralization. Both target types are suggested by the presence and distribution of widespread, anomalous-to-ore grade gold values and geochemical indicator element anomalies from rock and soil samples. 

A contract with Delong Drilling of Winnemucca, NV has been executed and drilling is scheduled to commence by mid-October. A series of reverse circulation holes will be drilled from several sites.

In late 2008, Inter-Rock completed a soil sampling program at RNY. A total of 230 samples were collected 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. The Inter-Rock soil sampling program confirmed the presence of three anomalous (>30 ppb Au) zones, where a gold anomaly was defined as a zone containing several contiguous samples containing greater than 30 ppb gold in soil. All three zones had been identified as anomalous gold zones by Australian Ores and Minerals (AOM) in their previous sampling program.

Previous mapping and interpretation revealed that the RNY gold prospect occurs in and around a Cretaceous biotite granodiorite stock that intruded a series of Permian metavolcanics and metasediments. The stock is several thousand feet long. The stock and Permian country rock were later intruded by latite porphyry dikes. NE-SW and NW-SE shear structures with cross cutting faults are also present in the stock. The Permian rocks are locally hornfelsed and pyrrhotized adjacent to the biotite granodiorite and latite porphyry intrusive bodies.

Both the intrusive and sediment/volcanic packages contain numerous areas of cross-cutting veinlets, stockworks, and veins of silica, calcite, and iron oxides. Hydrothermal alteration is prevalent throughout the anomalous area with phyllic/argillic alteration up to 50% quartz and 50% sericite.

AOM discovered gold mineralization at RNY in the 1990's by follow-up field examination of a Geoscan Mk. II airborne multispectral scanner anomaly. Their work comprised geological mapping, a closely-spaced soil geochemical program, analysis of rock chip, trenching (approx. 9800 feet) and road cut samples, petrographic work, and ground geophysical studies. Approximately 984 soil samples on 100 foot grid spacing and 1,160 rock chip samples in the area were collected and analyzed. The rock chip geochemistry returned gold to 7.0 ppm, silver to 39 ppm, arsenic to 690 ppm, and mercury to 9.7 ppm. The soil samples showed gold up to 2.1 ppm with large areas of plus 100 ppb. One trench reportedly revealed a zone of 90 feet grading 1.2 ppm gold. Inter-Rock recently acquired copies of the original assay certificates from AOM's 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.
