Rockgate Provides Additional Information to 2011 Technical Report

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 25, 2011) - Rockgate Capital Corp. (TSX:RGT) (the "Company") wishes to announce that as part of the review of the Company's Preliminary Short Form Prospectus by the British Columbia Securities Commission (the "BCSC"), the Company is issuing the following news release to clarify its previous disclosure.

The news release issued January 18, 2011 included both uncapped and capped values for the silver resource at the Falea project. The January 2011 Technical Report and Resource Estimate Update entitled "Falea Property Prefecture Of Kenieba District Of Kayes Republic Of Mali" dated February 4, 2011 (the "Technical Report") as filed on SEDAR on February 11, 2011 also provided both figures. The authors of the Technical Report concluded that the silver mineralization in the Falea deposit is "highly nuggety" and thus a capping strategy was applied to the silver values in the deposit in order to minimize the spreading of the high grade silver samples. Therefore, the Company advises that the figure for the uncapped silver resource should not be relied upon.

Table 1 below provides the capped figures for the silver resource, where the January 18, 2011 news release only reported the uncapped resource.

The technical report received in 2009 included a table providing various cut-off grades to show the variability of the deposit. The news release issued by the Company on January 18, 2011 reported resources using a 0.03% U3O8 cut-off while the technical report used a base case of 0.04%.

In order to provide consistency with the base case cut-off as selected by authors of the technical report, and using the capped values therefrom, the Company is pleased to highlight that the 2011 resource estimate provides an almost 7-fold increase in Indicated pounds of U3O8 and silver over the 2009 estimate as well as increases of almost double to the grade of both the U3O8 and silver in the Indicated category.

In order to reconcile disclosure made in the Company's 2009 Annual Information Form, both technical reports and the Company news releases, Table 2 below is taken directly from the technical report dated February 4, 2011 and reports the resource calculation using a variety of cut-off grades, with a 0.04% cut-off grade highlighted.
