TSX:RMX | NYSE AMEX: RBY

VANCOUVER, Nov. 17 /PRNewswire/ - Rubicon Minerals Corporation (RMX:TSX | RBY:NYSE-AMEX) is pleased to provide an update on its underground delineation drill program being carried out on part of the F2 Core Zone, part of the F2 Gold System at its 100%-owned Phoenix Gold Project located in the heart of the prolific Red Lake Gold District of Ontario. The results below pertain to the initial 4,277 metres of a 27,000 metre delineation drill program. In addition, Rubicon is carrying out approximately 40,000 metres of exploration drilling in the larger F2 Gold System. New delineation drill results are shown in Table 1 and Figures 2, 3, 4 and 6. 

The majority of the initial drill results are focused within +/-15 metres of the 305 metre level below surface. The delineation drilling is planned to further test a 150 metre (horizontal) x 200 metre (vertical) area within the F2 Core Zone of the F2 Gold System (Figures 1 and 5). Initial drill results appear to be outlining several structurally-hosted, discrete sub zones trending at multiple angles including a significant northwest-trending component (parallel to the regional F2 fold trend direction). The active cross-cuts now expose areas of the initial delineation drilling in the F2 Core Zone and separate northwest hanging wall zone (Figure 2, 3 and 4) and the Company plans to post pictures of the cross cuts by the end of the week on its website.

Delineation Drilling - Northwest Hanging Wall Area

Drilling northwest of the 305-05 drill station has intersected a previously unrecognized northeast trending subzone to the northwest of the main area of delineation drilling (Figure 2 and 6). Highlights include hole D305-05-016 which returned 16.59 oz/ton gold over 8.2 feet (568.9 g/t gold over 2.5 metres), including 41.03 oz/ton gold over 3.3 feet (1,406.8 g/t gold over 1.0 metre) and hole D305-05-020 returned 2.74 oz/ton gold over 6.6 feet (93.8 g/t gold over 2.0 metres), including 5.34 oz/ton gold over 3.3 feet (183.0 g/t gold over 1.0 metre). The majority of the mineralization in this zone is hosted by quartz veins, within a package of altered high titanium basalts and has currently been defined over a 55 metres strike length.

Delineation Drilling - Below 305 metre level

Hole D305-04-015 intersected 0.92 oz/ton gold over 19.0 feet (31.4 g/t gold over 5.8 metres) including a high-grade interval of 9.65 oz/ton gold over 1.6 feet (330.8 g/t gold over 0.5 metres) on the 310 metre level within strongly biotite-altered and quartz-veined high-titanium basalts (Figure 3 and 6). Hole D305-05-003A intersected a broad zone of 0.20 oz/ton gold over 72.2 feet (7.0 g/t gold over 22.0 metres) containing two separate high-grade intervals of 0.93 oz/ton gold over 7.9 feet (31.9 g/t gold over 2.4 metres) and 0.73 oz/ton gold over 4.6 feet (25.0 g/t gold over 1.4 metres).

Delineation Drilling - Above 305 metre level

Above the 305 metre level (Figure 4 and 6), hole D305-04-017 intersected 1.35 oz/ton gold over 9.8 feet (46.3 g/t gold over 3.0 metres) within a broader zone of 0.46 oz/ton gold over 31.2 feet (15.6 g/t gold over 9.5 metres) southwest of the 305 level drift on the 293 metre level. Northeast of the 305 level drift, drill hole D305-05-005 intersected 0.62 oz/ton gold over 16.4 feet (21.1 g/t gold over 5.0 metres) including 4.27 oz/ton gold over 2.0 feet (146.3 g/t gold over 0.6 metres) within a broader zone of 0.15 oz/ton gold over 87.2 feet (5.0 g/t gold over 26.6 metres) and D305-05-008 intersected 0.82 oz/ton gold over 9.8 feet (28.0 g/t gold over 3.0 metres) within quartz breccias contained within a broader zone of 0.17 oz/ton gold over 77.1 feet (5.7 g/t gold over 23.5 metres) respectively centered on the 296 metre level.

The gold mineralization both above and below the level occurs in multiple sub-parallel zones typically hosted by quartz breccias and variably altered mineralized high titanium basalt. To date, delineation drilling demonstrates that the mineralization is vertically continuous over the 20 metres tested and, based on previous wider-spaced drilling below the current level, it is expected that continuity will extend to depth.

"The F2 Core Zone delineation holes confirm and extend results from wider spaced drilling and also provide evidence of new, previously unidentified sub-zones. We look forward to our initial resource estimate before month end as well as further results from the delineation drilling and additional exploration drilling designed to further test the limits of the large F2 Gold System," stated David Adamson, President and CEO.

Assaying and Qualified Person
Assays were conducted on sawn NQ-sized half core sections. Delineation drilling intercepts represent horizontal thickness which, at this time, are interpreted to be true thickness. 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. Check assays on 5% of samples are carried out at a third party independent laboratory. Gold standards were prepared by CDN Resource Laboratories Ltd. Work programs in this release were supervised by Terry Bursey, P.Geo., Regional Manager for Rubicon and the project 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", "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 before a meaningful resource calculation can be completed.

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 accurate, 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.


The Toronto Stock Exchange has not reviewed and does not accept responsibility for the adequacy or accuracy of this release.
