Rubicon's Phoenix Gold Project Receives Final Three Permits and is now Fully Permitted for Potential Future Production

VANCOUVER, March 21, 2012 /CNW/ - Rubicon Minerals Corporation (RMX:TSX | RBY:NYSE-AMEX) ("Rubicon") is pleased to announce that the amendments to the Permit to Take Water, the Industrial Sewage Certificate of Approval and the Air Certificate of Approval, pertaining to its 100% owned Phoenix Gold Project located in the heart of the prolific Red Lake Gold district, have been accepted and approved by the Ontario Ministry of Environment. With these final approvals in hand, and combined with its existing Closure Plan, Rubicon is now fully permitted to develop, construct and operate a potential mining and milling facility for the Phoenix Gold Project in Red Lake, Ontario.

David Adamson, Rubicon's President and CEO commented, "This is another important milestone for the Phoenix Gold Project and for Rubicon. We have a high-grade gold project in a safe political jurisdiction, we are funded to continue development as outlined in our Preliminary Economic Assessment and now we are fully permitted. Starting with the discovery in 2008, this has all been achieved in four years. This accomplishment is due to the hard work and dedication of our project team, the support of both the local and Aboriginal communities and the timely input and review by the Government of Ontario."

Preliminary Economic Assessment ("PEA")

The PEA is preliminary in nature as it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. The quantity and grade of reported inferred resources are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.

The PEA was prepared by AMC Mining Consultants with metallurgical and processing contributions from Soutex, and has an effective date of August 8, 2011. Individual contributing authors are H.A. (Bert) Smith, P. Eng. and J.M. (Mort) Shannon, P. Geo. of AMC, and S. Caron, ing. of Soutex. All are independent Qualified Persons as defined by NI 43-101.

These statements are based on a number of assumptions. The material assumptions upon which such forward-looking statements are based include, among others: that the demand for gold and base metal deposits will develop as anticipated; that the price of gold will remain at levels that will render the Phoenix Gold Project economic; that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts and supplies, labour disturbances, interruption in transportation or utilities, or adverse weather conditions; that the Company will meet its estimated timeline for the development of the Phoenix Gold Project; that the Company will continue to have the ability to attract and retain skilled staff; that the mineral resource estimate as disclosed in the Company's August 8, 2011 technical report (the "Technical Report") will be realized; that there are no material unanticipated variations in the cost of energy or supplies, or in the pre-production capital and operating cost estimate as disclosed in the Technical Report; assumptions regarding general market conditions, timing and receipt of regulatory approvals; the ability of Rubicon 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.
