Rolling Rock Resource's Domain Project in Northern Manitoba Returns Drill Results of 4.61 gpt Gold Over 15.25 Metres Including 7.29 gpt Gold Over 9.0 Metres

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 21, 2008) - Rolling Rock Resources Corporation (TSX VENTURE:RLL) is pleased to report that it has received assays from the recently completed Phase II drill program undertaken on the Domain Project in northern Manitoba.

Scott Angus, President of the Company, stated that: "this 2008 winter program was designed to both follow up favorable drill results from previous drilling and to test undrilled projections of known mineralization that are strongly supported by airborne and ground geophysics. The drill results suggest that gold mineralization in the B Zone is increasing in width and grade to the northwest with the better values as listed above occurring in the westernmost 220 metres and that a significant drill program is warranted to follow up these very encouraging results."

This program which consisted of 2,654.5 metres of diamond drilling in 17 holes returned significant gold results from 8 drill holes on the B Zone. Drill intercepts from the B Zone follow:

(true thicknesses are estimated to be 75% of drill intercepts)


Of particular significance is that the B Zone remains completely open along strike. The interval in drill hole RR-08-20 is from the most north-westerly hole completed on the zone to date. The B Zone, which is presently defined by drilling over a strike length of 700 metres, is reflected by a strong ground electromagnetic and magnetic geophysical signature which continues for at least another 350 metres along a strike in a northwesterly trend.

Drill holes RR-08-11 to RR-08-18 and RR-08-27, which were drilled to the southeast of the B Zone, intersected sections of silicification and mineralization; all returned values of less than 2 gpt gold.

In addition to the B Zone, the Domain Project covers a number of geophysical anomalies suggestive of mineralized structures that are untested, and a number of zones with known gold intercepts that warrant additional drilling. Anomaly A, located approximately 100 metres to the north of the B Zone, is currently the most prospective target. Previous work outlined a 1.8 kilometre coincidental magnetic and VLF-EM conductor. Drilling of a 100 metre segment of the trend by Canico in the late 1970's and mid 1980's intersected anomalous gold values in all four drill holes. Results included a 4.6 metre intercept averaging 4.60 gpt gold and a 1.32 metre intersection averaging 12.59 gpt gold. Historic exploration data was collected before the introduction of NI 43-101, and is presented for information purposes only. The Company has no way of verifying the results and the historical data should not be relied upon.

The property is host to numerous steeply dipping, northwest trending gold-bearing structures up to 3.5 kilometres long and at least 100 metres in down-dip extension. These structures are associated within silicified zones containing variable amounts of pyrite, pyrrhotite, magnetite and arsenopyrite coincident with extensive ground and airborne geophysical anomalies and are structurally and geologically comparable to Rolling Rock's Monument Bay property located 150km to the east. Monument Bay hosts a January 2008 NI 43-101 compliant inferred resource, using a cut-off of 3 gpt, of 4,888,000 tonnes grading 6.01 gpt contains 944,000 ounces of gold.

Rolling Rock is highly encouraged with the results of the 2008 exploration program and in the Company's opinion a significant drill program is warranted to follow up these very encouraging results. Rolling Rock is presently earning up to a 65% interest in the Domain Project from New Dimension Resources (TSX VENTURE:NDR) and a joint venture will then be formed to continue exploration.

The Domain Property totals 14,000 hectares situated in the Gods Lake greenstone belt. It is located 15 kilometres east of the community of Oxford House and is accessible by winter road. Oxford House, with a population of approximately 2,500 people, has good infrastructure, including hydroelectric power and an all-season airport with daily flights to Winnipeg and Thompson.

Quality control on the Domain Project includes chain-of-custody protocol as well as systematic submittals of standards, duplicates and blank samples into the flow of samples produced by drilling. At Domain, drill core is sawn into halves with one half being sent for analysis and the other kept for future reference. All samples are prepared and assayed by TSL Laboratories, Saskatoon, Saskatchewan. At TSL, samples were fire assayed using a two assay ton sample. Samples that assayed greater than 30 gpt gold were submitted for screen analysis. A technical report in compliance with NI 43-101 on the Domain Property authored by J.T. Shearer M.Sc., P.Geo. dated August 21, 2005 can be viewed on Rolling Rock Resources company profile at www.sedar.com. A map showing the drilling will be available at www.rollingrockresources.com.
