-1.01 oz/ton gold over 22.0 feet in F2 Core Zone - - new zone in northern target area 0.91 oz/ton gold over 55.8 feet -

TORONTO, July 6 /PRNewswire-FirstCall/ - Rubicon Minerals Corporation (RMX:TSX: / RBY:NYSE-AMEX) is pleased to provide an update of the latest diamond drill results at its 100%-owned Phoenix Gold Project, located in the heart of the prolific Red Lake Gold District of Ontario. All new drill results are shown in Table 1 and Figures 1 and 2.

Core Zone - new intercept confirms horizontal thickness and vertical continuity of high grade gold

Drill hole 305-11 tested the F2 Core Zone (target area 1 in figure 2) in the area of the intended cross-cut approximately 21 metres vertically above previously reported drill hole 305-05 (1.24 oz/ton gold over 22.6 feet (42.5 g/t gold over 6.9 metres), part of a broader vein zone grading 0.59 oz/ton gold over 49.2 feet (20.1 g/t gold over 15.0 metres)). Hole 305-11 intersected 1.01 oz/ton gold over 22.0 feet (34.7 g/t gold over 6.7 metres) as part of a wider vein zone grading 0.58 oz/ton gold over 53.1 feet (20.1 g/t gold over 16.2 metres). Both holes were drilled sub-horizontally and intersected the gold-bearing zone at near right angles and thus are interpreted to be true horizontal thicknesses. The F2 Core Zone, which is one zone within the larger F2 Gold System, is currently defined over a strike length of 75 metres (246 feet) a vertical extent of 600 metres (1968 feet) and is open vertically and along strike. Underground development is drifting to the F2 Core Zone on the 305 level following which delineation drilling will be carried out to outline the gold zones in more detail. A long section of the F2 Core Zone showing the distribution of g/t gold multiplied by metres (gram-metre product) is posted on the corporate website, www.rubiconminerals.com.

"305-11 confirms the presence of both exceptional gold grades and thicknesses in the core zone directly in the area where our cross-cut is planned. This bodes well for our objective to build significant tonnes and grade in the core zone as a pre-curser to mining," stated David Adamson, President and CEO.


Northern Extension Target Area - New Zone Intersected

Drilling from surface in target areas 4 and 6 continues to intersect significant high-grade gold as in-fill drilling further expands gold mineralization this area. Hole F2-102 returned 0.91 oz/ton gold over 55.8 feet (31.2 g/t gold over 17.0 metres) including 1.18 oz per ton gold over 37.7 feet (40.5 g/t gold over 11.5 metres), all developed within a wider zone of 0.47 oz/ton gold over 118.1 feet (16.0 g/t gold over 36.0 metres). Hole F2-101 returned multiple high-grade gold intercepts down hole (Table 1 and Figures 1 and 2) including a quartz veined zone grading 1.10 oz/ton gold over 9.8 feet (37.7 g/t gold over 3.0 metres) including 5.87 oz/ton gold over 1.6 feet (201.2 g/t gold over 0.5 metres).

Below target 4, in target area 6 (Figure 2) underground hole 122-58 intersected 1.07 oz/ton gold over 3.0 feet (36.7 g/t gold over 0.9 metres) and 0.91 oz/ton gold over 3.3 feet (31.1 g/t gold over 1.0 metres). These intercepts provide additional confirmation of the high-grade gold potential at depth in the northern target area.

"Our ongoing '9X' drill program continues to return excellent results through the system on a regular basis. Hole F2-102 looks to be a very significant hole that rivals the best holes drilled to date in the F2 Gold System. We believe these results are further confirmation that the F2 mineralizing system has the ability to develop excellent horizontal thickness and impressive gold grades in several zones beyond the F2 Core Zone," stated David Adamson, President and CEO.

Southern Extension Area - Depth extension of 122-10 Zone

Surface drill hole F2-94 in target area 5 was designed to test for the extension to depth of the previously reported 122-10 Zone reported September 14, 2009 which intersected 0.40 oz/ton gold over 147.3 feet (13.7 g/t gold over 44.9 metres) including 3.82 oz/ton gold over 4.9 feet (130.9 g/t gold over 1.5 metres). F2-94 intersected 0.65 oz/ton gold over 22 feet (22.3 g/t gold over 6.7 metres), including 1.05 oz/ton gold over 9.8 feet (36.0 g/t gold over 3.0 metres) and 2.15 oz/ton gold over 1.8 feet (73.7 g/t gold over 0.5 metres) 225 metres below 122-10 (see Table 1). This hole indicates significant potential to expand the 122-10 Zone to depth.
