- 10.55 oz/ton gold over 5.9 feet (361.7 g/t gold over 1.8 metres) - - plus separate 0.27 oz/ton gold over 28.2 feet (9.1g/t gold over 8.6 metres) in new drill hole - - updated long section illustrates gold system now extends over 1800 ft (550 metres) - TORONTO, July 8 /PRNewswire-FirstCall/ -- Rubicon Minerals Corp (RMX.TSX:RBY.AMEX) is pleased to announce a further update of drill results from its F2 Zone, part of the 100%-controlled Phoenix Gold Project, located in the heart of the prolific Red Lake gold district of Ontario. Previous drilling (see news release dated May 5, 2008), has identified significant zones of mineralization (the F2 Zone) which includes high-grade intercepts (e.g., 73.2 g/t gold over 3.0 metres, 52.6 g/t gold over 7.4 metres, 24.4 g/t gold over 17.0 metres including 36.5 g/t gold over 8.0 metres, 42.4 g/t gold over 11.0 metres, 28.7 g/t gold over 15.5 metres) and extensive gold-bearing sulphide zones (e.g., 6.0 g/t gold over 17.0 metres, and 8.3 g/t gold over 30.0 metres). Additional Bonanza Grade in F2-19 --------------------------------- Additional assay results returned from hole F2-19 confirm a second bonanza grade gold intercept of 10.55 oz/ton gold over 5.9 feet (361.7 g/t gold over 1.8 metres), including 23.7 oz/ton gold over 2.6 feet (811 g/t gold over 0.8 metres), at a vertical depth of 327 metres. This intercept is farther up-hole than a previously released high grade intercept (see news release dated June 16, 2008) of 3.55 oz/ton gold over 3.3 feet (121.7 g/t gold over 1.0 metres). F2-19 is a 165 foot (50 metre) step-out hole from the main F2 Zone. New Drill Hole F2-21 Intersects Gold Zone - Hole F2-20 indicates system present at depth ------------------------------------------------------------------------- Hole F2-21, drilled from a barge situated close to the F2 Zone and designed to test for extensions of known zones has intersected a complex sulphide and quartz breccia zone grading 0.27 oz/ton gold over 28.2 feet (9.1 g/t gold over 8.6 metres), including a high-grade sub interval of 2.85 oz/ton gold over 1.6 feet (97.9 g/t gold over 0.5 metres) at a vertical depth of 171 metres below surface. In general, vein angles to core axis are moderate to high indicating the zone has been intersected at a reasonable angle. Further mineralization observed down-hole has been sampled and sent for assay. Drill hole F2-20, designed to test for mineralization at depth has intersected sulphide rich mineralization 695 metres below surface and contains up to 7.4g/t gold over 4.0 metres, including 12.0 g/t gold over 2.0 metres. This intercept is significant since it suggests that the gold mineralizing system continues to depth. A compilation of significant gold intercepts released to date from the F2 Zone is listed in Table 1. Updated long section shows system size increasing and demonstrates northwest plunge control ------------------------------------------------------------------------- Since discovering the F2 zone in late February, 2008, significant gold mineralization has now been intersected over a vertical distance of 1800 feet (550 metres) and over an interpreted strike length of 525 feet (160 metres). An updated north-south composite vertical section (Figure 1) suggests that the mineralized envelope displays a steep plunge to the northwest and is open for follow up. A plan map of the F2 Zone shows the trace of the composite section and the interpreted trend of gold mineralization (Figure 2). Ongoing drilling is designed both to infill and expand the current mineralized envelope both down-plunge and along strike. As stated in previous news releases, considerable drilling is required to better understand the distribution of gold mineralization in three dimensions. Management believes this is best accomplished by drilling from underground utilizing the nearby shaft and workings situated 450 metres from the F2 Zone. "We are excited to see both bonanza grade and thicker gold bearing sulphide sections continuing to expand the F2 gold system. While this discovery is in its infancy, it is encouraging to see that the major components documented at the Red Lake Mine are present at the F2 Zone. Drilling is continuing and as recently announced we are advancing plans to explore the F2 Zone and surrounding area from underground by de-watering the shaft," said David Adamson, President and CEO. Second Barge Drill Rig Ordered ------------------------------ A second barge to facilitate drilling on the lake has been ordered. Once commissioned, land-based drilling from the peninsula will be discontinued in favour of barge drilling to allow greater flexibility and control.

Adamson" President & CEO Assays were conducted on sawn NQ-sized half core sections. Further drilling is required before the true widths of reported intercepts can be determined. The saw blade is routinely cleaned between samples when visible gold is noted during logging and sampling of the drill core. Assays were conducted by SGS Minerals Services using standard fire assay on a 30 gram (1 assay ton) sample with a gravimetric finish procedure. Assays are uncut as is standard practice in Red Lake. Standards, blanks and check assays were included at regular intervals in each sample batch. Gold standards were prepared by CDN Resource Laboratories Ltd. Work programs are supervised by Terry Bursey, P.Geo. the project Qualified Person under the definition of NI 43-101.
