VANCOUVER, June 1, 2011 /PRNewswire/ – Rubicon Minerals Corporation (TSX: RMX) (NYSE-AMEX: RBY) is pleased to provide final delineation
results from its planned 27,000-metre delineation program carried out
on part of the F2 Core Zone, at its 100%-owned Phoenix Gold Project
located in the heart of the prolific Red Lake Gold District of Ontario.
The delineation program was designed to infill an area 100 meters above
and below the 305 metre level (below surface), over a strike length of
150 metres at a nominal drill spacing of 15 metres. To this end, 264
holes were drilled from three underground drill stations for a total of
over 35,000 metres.  The ’9X’ exploration drill program to continue to
expand and infill the F2 Gold System is ongoing.

Latest delineation drill results received since the April 11, 2011 news
release are shown in Table 1 and 2, and Figures 1 through 6. A complete
listing of results from the delineation drill program is available on
the Company’s website at www.rubiconminerals.com.

Highlights of the drilling include 1.06 oz/ton gold over 13.4 feet (36.4 g/t gold over 4.1 metres) in drill hole D305-04-069 (estimated true width is interpreted to be
approximately 70% of core length), 4.32 oz/ton gold over 11.5 feet (148.1 g/t gold over 3.5 metres) in drill hole D305-04-093 (estimated true width is interpreted to be
approximately 25% of core length), 0.66 oz/ton gold over 16.7 feet (22.5 g/t over gold 5.1 metres) in drill hole D305-06-072 (estimated true width is interpreted to be
approximately 60% of core length) and 0.45 oz/ton gold over 20.0 feet (15.4 g/t gold over 6.1 metres) in drill hole D305-05-088 (estimated true width is interpreted to be
approximately 50% of core length).

Figure 5 is a composite long section showing the gold intercepts in the
delineation area before and after the delineation drill program. This
figure shows that the main objective of the program, to in-fill the
target area, has been met. The success and experience gained from this
program provides encouragement for future delineation programs. The
in-fill drilling has confirmed the presence of multiple gold zones
trending dominantly northeast (F1). The main trend is locally cross-cut
by northwest (F2) structures which can contain appreciable visible
gold. In general, mineralization is hosted within the main basaltic
package of rocks and within locally adjacent felsic intrusive rocks and
their associated contacts.

Figure 6 is a composite cross section illustrating the geometry and
interpreted continuity of zones in the delineation area.

“The delineation program has been very successful in confirming the
continuity of the mineralization in this part of the F2 Gold system. We
plan to apply this approach to other shallow parts of the F2 Gold
System, most obviously above and below the current delineation area
with the objective of upgrading our current inferred resources in these
areas.” stated David Adamson, President and CEO.

Holes with the prefix ‘D305′were drilled from underground on the 305
metre level and are part of the delineation program. Assays are uncut.
Reported results satisfy the following cut-off criteria: An intercept
equal to or greater than 10 g/t gold (gram) x (metre) product value and possessing an average grade of equal to or greater than 5.0 g/t gold.
All reported widths are core length.  Estimated true widths are based
on visual examination of core angles and by calculating drill hole dip
and azimuth relative to interpreted zone geometries. Such estimated
true widths may be subject to change based on information from future
drilling and underground mapping. Where the estimated true width is
labelled ‘not yet known’, further drilling or other information is
required to allow an interpretation of the estimated true widths.

A complete listing of results to date for the F2 Gold System is
available at www.rubiconminerals.com.

<10.0g/t gold)

Holes with the prefix ‘D305′were drilled from underground on the 305
metre level and are part of the delineation program. Assays are uncut.
Reported results satisfy the following cut-off criteria: An intercept
equal to or greater than 10 g/t gold (gram) x (metre) product value and possessing an average grade of equal to or greater than 5.0 g/t gold.
All reported widths are core length.  Estimated true widths are based on visual examination of core angles and
by calculating drill hole dip and azimuth relative to interpreted zone
geometries. Such estimated true widths may be subject to change based
on information from future drilling and underground mapping. Where the
estimated true width is labelled ‘not yet known’, further drilling or
other information is required to allow an interpretation of the
estimated true widths.

A complete listing of results to date for the F2 Gold System is
available at www.rubiconminerals.com.

Assaying, Data Verification and Qualified Person
All reported intercepts (widths) are core lengths except as indicated by estimating the
approximate true width of the reported interval. True width estimates
are based on the on-going geological and structural interpretation of
the host units and the relation to the gold mineralization based on
drill core analysis, including core angles and hole orientation to the
host unit, in conjunction with underground observations. Drill core
assays were conducted on sawn NQ-sized half core sections. The saw
blade is routinely cleaned between samples when visible gold is noted
during logging and sampling of the drill core. All assays were
conducted by SGS Minerals Services using standard fire assay on a 50
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.
Check assays on 5% of samples are carried out at a third party
independent laboratory. Gold standards were prepared by CDN Resource
Laboratories Ltd. Phoenix Project exploration, drill work programs and
all data forming the basis of this release were supervised and verified
by Terry Bursey, P.Geo., Regional Manager for Rubicon and a Qualified
Person under the definition of NI 43-101.

Forward Looking Statements
This news release contains statements that constitute “forward-looking
statements” within the meaning of Section 21E of the United States
Securities Exchange Act of
1934 and “forward looking information” within the meaning of applicable
Canadian provincial securities legislation (collectively,
“forward-looking statements”) . Forward-looking statements often, but
not always, are identified by the use of words such as “seek”,
“anticipate”, “believe”, “plan”, “estimate”, “expect”, “targeting” and
“intend” and statements that an event or result “may”, “will”, “would”,
“should”, “could”, or “might” occur or be achieved and other similar
expressions. Forward-looking statements in this document include
statements regarding the timing and nature of future exploration
programs which are dependent on projections which may change as
drilling continues, or if unexpected ground conditions are encountered.
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 the extent 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 Gold System are interpreted to show
similarities to nearby gold producing mines owned by third parties,
this should not be interpreted to mean that the F2 Gold System has, or
that it will, generate similar reserves or resources. Significant
additional drilling is required at F2 to fully understand system size.

The forward-looking statements that are contained in this news release
are based on various assumptions and estimates by the Company and
involve a number of risks and uncertainties. As a consequence, actual
results might differ materially from results forecast or suggested in
these forward-looking statements. Forward-looking statements involve
known and unknown risks, uncertainties, assumptions and other factors
that may cause the actual results, performance or achievements of the
Company to be materially different from any future results, performance
or achievements expressed or implied by the forward-looking statements.
Factors that could cause the actual results to differ include market
prices, results of exploration, availability of capital and financing
on acceptable terms, inability to obtain required regulatory approvals,
unanticipated difficulties or costs in any rehabilitation which may be
necessary, market conditions and general business, economic,
competitive, political and social conditions. These statements are
based on a number of assumptions, including assumptions regarding
general market conditions, timing and receipt of regulatory approvals,
the ability of the Company and other relevant parties to satisfy
regulatory requirements, the availability of financing for proposed
transactions and programs on reasonable terms and the ability of
third-party service providers to deliver services in a timely manner.
Although the Company has attempted to identify important factors that
could cause actual results to differ materially from those expressed or
implied in forward-looking statements, there may be other factors which
cause actual results to differ.

Forward-looking statements contained herein are made as of the date of
this news release and the Company disclaims any obligation to update
any forward-looking statements, whether as a result of new information,
future events or results or otherwise, except as required by applicable
securities laws. There can be no assurance that forward-looking
statements will prove to be accu
rate, as actual results and future events could differ materially from
those anticipated in such statements. Accordingly, readers should not
place undue reliance on forward-looking statements.
