West Kirkland Mining and Rubicon Minerals Announce an Agreement on Large Claim Block on the Long Canyon Trend, Nevada

June 27, 2011

VANCOUVER, BRITISH COLUMBIA – West Kirkland Mining Inc. (WKM: TSX-V) ("West Kirkland" or the "Company") and Rubicon Minerals Corporation, (TSX:RMX, NYSE AMEX: RBY) ("Rubicon") have entered into an agreement whereby West Kirkland can earn a majority stake in mineral rights held by Rubicon covering approximately 351 square miles (909 sq. kilometers) in the Long Canyon Trend of north eastern Nevada, while allowing Rubicon to retain a significant interest in any future discovery.

Recent discoveries of gold by Fronteer Gold (now Newmont) and others at Long Canyon have resulted in a paradigm shift in the belt, opening up new potential for discovery of large scale gold deposits.  Long Canyon is located along a north east structural setting in rocks only recently discovered to be favorable hosts for gold.

West Kirkland can earn a 51% interest from Rubicon in a portion of the Rubicon property package directly across the valley to the north east from the Long Canyon gold deposit. There are gold showings noted in historic work in this part of the overall property package, also there are unexplored north east trending structures, outside areas of historic exploration.  These newly recognized structures are an immediate target for West Kirkland's planned exploration program.

Further to the north, West Kirkland can earn a 60% property interest in a portion of the Rubicon property package of the Long Canyon Trend adjoining the KB and TUG properties that are optioned by West Kirkland from Fronteer.  The resulting consolidation of property interests provides a significant new opportunity. West Kirkland is currently drilling on the TUG property in the area of a shallow historic gold resource. Drilling is ongoing.

R. Michael Jones, President of West Kirkland said, "We now have the benefit of a newly recognized deposit setting in the best gold camp in the United States and an enormous land position to explore across. This transaction follows West Kirkland's approach to acquire large majority positions in known gold trends with new information where we can work these trends systematically. "

David Adamson, President and CEO of Rubicon said "We are pleased to see this large property portfolio well funded through this agreement and moved forward by a solid dedicated team at West Kirkland who has a considerable track record of discovery. This transaction allows us to maintain our focus in Red Lake while allowing us to retain a meaningful interest in any potential discovery on our properties in Nevada".

Details

West Kirkland can earn an initial 51% interest in any of the properties where Rubicon holds a 100% interest by making the expenditures outlined in the table below over four years and Rubicon will retain a 49% interest in the properties.  The first year's expenditure is a firm commitment of $2,000,000. 

West Kirkland can increase its interest to 60% by completing a pre-feasibility study or spending an additional $4,000,000 in exploration and development work, in which case Rubicon will retain a 40% interest in the properties. For properties in which Rubicon holds a 75% interest, West Kirkland is able to earn up to a 51% interest in such properties by making the outlined expenditures.

Annual Period Annual Minimum of Exploration and Development Expenses Aggregate Exploration and Development Expenses
First Annual Period $2,000,000 (firm commitment) $2,000,000
Second Annual Period $3,000,000 $5,000,000
Third Annual Period $5,000,000 $10,000,000
Fourth Annual Period $5,000,000 $15,000,000

West Kirkland is the project operator. Initial exploration will be targeted across the valley from Long Canyon and adjacent to the KB and TUG deposits. The property positions included in the Rubicon transaction are in the "checker board" of Nevada where each block of 1 square mile of property has another owner on the alternate one square mile square. As exploration progresses further consolidation of mineral rights may be required. Initial exploration will focus well within the owned blocks.
