Rubicon and Solitaire Commence 3,300 metre Drill Program at Red Lake North Project



    TORONTO STOCK EXCHANGE SYMBOL: RMX
    AMEX SYMBOL: RBY

    TORONTO, Aug. 14 /CNW/ - Rubicon and Solitaire Minerals Corporation
(TSX-V: SLT) are pleased to announce the start of a 3,300 metre drill program
at the Red Lake North Project. The property is under option to Solitaire
Minerals Corp. ('Solitaire') who is required to fund $2.5 million of
exploration over four years (prior to May 30, 2010) to earn a 55% interest.
Through an aggressive exploration program, Solitaire and Rubicon are advancing
the property and have identified four distinct target areas for drill testing
along a 12-kilometre strike length of prospective stratigraphy.

    The Red Lake North project is separated into two distinct packages of
ground:

    The Red Lake North Main Block

    This block which is the focus of this drill program, is directly along
strike from both the Main Discovery Zone (MDZ) and Upper Duck Zone (UDZ),
currently being explored by Goldcorp/Planet Exploration Inc on the Sidace Lake
Property. Based on three holes drilled by Rubicon in 2005 that intersected the
prospective quartz-sericite schist altered horizon as well as geophysical
interpretation, the extension of gold-bearing stratigraphy that hosts the MDZ
continues southwest onto the Red Lake North Main Block.

    The Sidace Lake Area

    The Sidace Lake Area claims are situated on the up-dip and down-dip
extensions of the Goldcorp/Planet MDZ. The property is dominated by a package
of Balmer assemblage mafic and ultramafic volcanic rocks which are overlain by
altered intermediate sediments. Solitaire funded a deep-targeting program on
this claim in the fall and winter of 2006/2007, but was limited by the depth
capacity of the drill rig. A drill rig capable of reaching a depth of 2,500
metres has been contracted for late September 2007 for planned follow-up
drilling.
