Gray Rock Provides Year End Summary and Outlook for 2009

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 27, 2009) - Gray Rock Resources Ltd. (the "Company") (TSX VENTURE:GRK) is pleased to present a review of work completed in 2008 and our plans for 2009. We are very enthused about the potential of our Silver Stream Property in southwest British Columbia and JC Claims in Nevada, especially as the demand for gold and silver remains high.

Silver Stream Property: Potential for Bulk tonnage

At the 100%-owned Silver Stream Property, we completed additional core sampling of holes completed in 2005 and 2007 and exploratory rock sampling. Our goal was to test the property's bulk tonnage potential based on results from drill hole SS-05-01. From a depth of 56.2 meters, chert breccias and argillite were encountered with the following values:



From (m) To (m) Width (m) Au g/t
-------------------------------------------
56.2 78.33 22.13 2.997
56.2 78.33 22.13 2.91 (re-assay)


Core recovery was extremely low after 78.33 meters strongly suggesting a major shear zone and therefore the possibility of a thicker mineralized zone.

Two Phase Program for 2009: Soil Sampling and Trenching

Phase I will consist of additional soil sampling on the West Zone near drill SS-05-01. We also will establish a new soil sampling grid extending north and west of the West Zone.

Phase II will consist of trenching on the following targets:

1) Reopen old trenches on the West Zone and sample for bulk tonnage potential.

2) Anomalies outlined by the 2009 Phase I soil sampling.

3) Three additional gold-in-soil anomalies outlined by previous work. These have returned values up to 2.95 g/t Au, but were never trenched.

The program is supervised by Ursula Mowat, P. Geo., a qualified person as per National Instrument 43-101.

Silver Stream History and Overview

First explored in 1988, the Silver Stream property has produced a number of anomalous-to-significant gold showings in sampling, trenching and drilling. Although still an "early-stage" property, a July 2006 Technical Report (NI 43-101 compliant) states:

"...the nature of the mineralization seen in the known showings in the context of the Bridge River camp show the property has good potential to develop economic gold mineralization."

The renowned Bralorne gold mine, which between 1932 and 1971 produced 4.1 million ounces of gold, lies about 25 kilometers southwest of Silver Stream. The average grade of the Bralorne mine complex was 0.52 opt gold, and it remains the largest historic gold producer of the Canadian Cordillera.

JC Claims, Nevada - Mapping and Sampling Proposed

No work was conducted on our 100%-owned JC Claims in 2008. However, for the coming season we are considering proposals for geological mapping and sampling to define new targets for drilling. Located on the prolific Battle Mountain/Cortez gold trend, this highly prospective property is centered on exposed mineralized lower plate rocks of the Roberts Mountain Thrust. The claims include surrounding areas of poorly exposed and prospected lower plate rocks, often covered by a thin veneer of valley-fill gravel.

These characteristics make the JC Claims a prime target for discovery of Carlin-Style gold mineralization. The region has hosted a number of gold discoveries in the past decades, including Tonkin Springs and Gold Bar.

The Company was incorporated in 1950 and has property located in Lander County, Nevada and near the historic Bralorne and Pioneer Gold mines. These mines produced in excess of 4 million ounces of gold. Infrastructure is in place at Bralorne and a town nearby to draw skilled labour. Custom milling at the Bralorne mill may be an option for the Company provided it is successful in finding sufficient ore.
