    VANCOUVER, April 27 /CNW/ - Rubicon Minerals Corporation (RMX.TSX:
RBY.NYSE-AMEX) is pleased to announce results of ice-based drilling from its
100%-controlled Phoenix Gold Project, located in the heart of the prolific Red
Lake Gold District of Ontario. The Company is conducting drill programs
designed to expand the F2 Zone from which numerous significant high-grade and
bonanza-grade gold intercepts have been reported (see news releases from March
12, 2008, onwards).
    Results in this release are focused in the northeast and southwest target
areas respectively, for which positive initial results were released February
11 and March 23, 2009. See Figures 1 to 3 for drill hole location maps and
sections. For a complete tabulation of all results from the F2 Zone, please
refer to

    F2 Zone northeast extension drilling

    New high-grade gold results from this area include 1.15 oz/ton gold over
12.1 feet (39.3 g/t gold over 3.7 metres) in hole F2-59 and 6.96 oz/ton gold
over 3.3 feet (238.6 g/t gold over 1.0 metre) in hole F2-58. Host basalts in
this area contain numerous additional significant gold intercepts (see Table
1) developed within wide mineralized intervals, e.g., 0.36 oz/ton gold over
98.4 feet (12.3 g/t gold over 30.0 metres) in hole F2-57. Results from the
northeast extension area are significant because:

    1) New results show that the northeast area represents an expansion of
       the F2 core system rather than a separate, isolated area (see Figure
       1, 2 and 3).

    2) The system remains open for exploration further to the north/northeast
       and to depth.

    3) Newly reported high-grade gold intercepts in hole F2-58, and
       previously reported high-grade gold in hole F2-57 (2.01 oz/ton gold
       over 13.1 feet (68.8 g/t gold over 4.0 metres)) occur approximately
       100 metres from the core of the F2 Zone. Taken together, these results
       indicate the potential to significantly expand the core high-grade
       gold system and indicate potential for a significant, new high-grade
       gold zone.

    4) The potential to further expand the system to the northeast and
       discover additional gold zones is considered to be high. This is
       evidenced by the new high-grade gold intercept in hole F2-59 which
       occurs 40 metres from the wide intercept reported in hole F2-57 and,
       separately in hole F2-55 which intersected gold mineralization to the
       east of previous holes in an untested area.

    F2 Zone core area drilling

    Hole F2-61B returned a thick intersection of mineralized basalts
averaging 0.11 oz/ton gold over 160.7 feet (3.6 g/t gold over 49.0 metres)
that contains several higher grade sections up to 0.96 oz/ton gold over 3.3
feet (33.0 g/t gold over 1.0 metres). This thick intersection of the favoured
host lithology offers potential for significant additional gold mineralization
in this area.

    F2 Zone southwest extension drilling

    New high-grade gold intercepts in this area are highlighted by 3.62
oz/ton gold over 9.84 feet (124.2 g/t gold over 3.0 metres) in hole F2-52.
This intercept is interpreted to be the down-plunge continuation of the F2
gold system and demonstrates the excellent potential for further high-grade
gold throughout this area. Hole F2-52 also returned numerous additional
significant gold intercepts over a broad interval at moderate depths (see
Table 1). In addition, holes F2-52 and F2-56 intersected thick, near surface
mineralization including 0.12 oz/ton gold over 84.0 feet (4.1 g/t gold over
25.6 metres). These broad, near surface zones contain several higher grade
gold intervals (see Table 1) and offer excellent potential for further gold
discoveries down plunge to the southwest. These will be drill-tested by holes
collared on the 400 foot level from underground which is scheduled to commence
by the end of May, 2009. Gold mineralization remains open further to the
southwest and to depth.

    Footwall East area

    One reconnaissance drill hole located approximately 1.4 kilometres to the
northeast of the F2 Zone was completed and intersected 0.37 oz/ton gold over
3.3 feet (12.8 g/t gold over 1.0 metres) and 0.1 oz/ton gold over 9.8 feet
(3.6 g/t gold over 3.0 metres) in mafic host rocks. The presence of gold
bearing units in this major step out is encouraging and demonstrates potential
for new gold discoveries well beyond the extensive F2 gold system itself.
    "We are very encouraged that high-grade gold zones continue to be
intersected in every new area we drill at F2. When we review all of our data
to date, based on over 45,000 metres of drilling, we see that the F2 basalts,
which are the preferred host for gold mineralization, display good continuity.
We now recognize that these gold-mineralized F2 basalts can be traced 700
metres laterally and up to 1101 metres vertically. Within this area, drilling
to date has been very successful in consistently intersecting significant gold
mineralization. While this drilling has documented extensive gold
mineralization to date, only a small part of the total identified target area
has been drill tested and thus the potential for further expansion of the F2
gold system is considered to be very high. This expansion of the F2 Gold
System is the goal of our recently announced 80,000-metre drill program, which
has just commenced" stated David Adamson, President and CEO.

    Underground Update

    Dewatering of underground workings is complete and rehabilitation of the
underground workings, which are in good condition, is underway. It is
anticipated that drilling from the 400 foot level and the start of shaft
deepening will commence before the end of May, 2009.

    Assaying and Qualified Person

    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

    Forward Looking Statements

    This news release contains certain statements that may be deemed
"forward-looking statements". All statements in this release, other than
statements of historical fact, that address events or developments that the
Company expects to occur, are forward looking statements. Forward looking
statements are statements that are not historical facts and are generally, but
not always, identified by the words "expects", "plans", "anticipates",
"believes", "intends", "estimates", "projects", "potential", "suggest" and
similar expressions, or that events or conditions "will", "would", "may",
"could" or "should" occur. Forward-looking statements in this document include
statements regarding the timing and nature of future exploration programs
which are dependant on projections which will need to be confirmed when
underground work is commenced. In addition, areas of exploration potential are
identified which will require substantial drilling to determine whether or not
they contain similar mineralization to areas which have been explored in more
detail. The description of mineralized zones is not intended to imply that any
economically mineable estimate of reserves or resources exists on the Phoenix
project. Similarly, although geological features of the F2 Zone are
interpreted to show similarities to nearby gold producing mines owned by third
parties, this should not be interpreted to mean that the F2 zone has, or that
it will, generate similar reserves or resources. Significant additional
drilling is required at F2 to fully understand system size before a meaningful
resource calculation can be completed.
    Although the Company believes the expectations expressed in such
forward-looking statements are based on reasonable assumptions, investors are
cautioned that any such statements are not guarantees of future performance
and actual results or developments may differ materially from those projected
in the forward-looking statements. Factors that could cause the actual results
to differ materially from those in forward-looking statements include market
prices, exploitation and exploration successes, continued availability of
capital and financing, inability to obtain required shareholder or regulatory
approvals, and general economic, market or business conditions. Forward
looking statements are based on the beliefs, estimates and opinions of the
Company's management on the date the statements are made. Except as required
by applicable securities laws, the Company undertakes no obligation to update
these forward-looking statements in the event that management's beliefs,
estimates or opinions, or other factors, should change.
    These statements are based on a number of assumptions, including, among
others, assumptions regarding general business and economic conditions, and
the ability of third-party service providers to deliver services in a timely
manner. The foregoing list of assumptions is not exhaustive. Events or
circumstances could cause results to differ materially.

    The Toronto Stock Exchange has not reviewed and does not accept
