Rockgate Capital Corp.: Diamond Drilling Defining Large Roll-Front Uranium Deposit at Falea Project, Mali, West Africa

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 29, 2007) - Rockgate Capital Corp. (TSX VENTURE:RGT) (the "Company") is pleased to report the results of the Phase One drill program of 55 diamond drill holes totaling over 15,000 metres completed at the Falea uranium project in Mali, west Africa.

All Phase One drilling has been focused on the Central Zone of the Falea property, one of several known uranium occurrences on the property. The uranium mineralization of the Central Zone has an average thickness of 3.70 metres and an average grade of 0.10% U3O8 and remains open in almost every direction. The mineralization appears to be a classic, flat-lying, sandstone roll-front uranium deposit, bounded by mudstones. The core of the zone has a north-west trend of one kilometer in length, with an average width of 250 metres. The mineralized zone occurs at an average depth of between 260 and 275 metres. The consistency of this Proterozoic Sedimentary basin has resulted in 52 of the 55 diamond drill holes completed containing significant uranium concentrations. All results are from full assays and are not based on down-hole logging.

Assay results from the core of the Central Zone are listed in Table 1 and on the enclosed composite plan map.

(All thickness reported in Tables 1&2 are true width.)

Mineralization consists mainly of uraninite and minor coffinite contained in a coarse-grained, porous, sandstone unit, bounded on both sides by mudstones. Minor concentrations of copper sulphides and oxides commonly occur in close proximity to the uranium mineralization. The Central Zone occurs within one of three, north-south trending structural corridors identified by Cogema in the late 1970's from wide spaced (800x800 metre) drilling programs. The structural corridor hosting the Central Zone is understood to be over 6 kilometres in length and up to 1.5 kilometres in width. Known uranium mineralization (Bodi Area) also occurs over 2.5 kilometres north of the Central Zone within the same structural corridor. Rockgate is currently drill testing the Kania Sandstones at 200 metre spacing between the known Central Zone and Bodi Area.

The 100x100 metre spaced Phase 1 diamond drilling program was started in March 2007, with the results from the first two holes reported on May 16, 2007. In order to properly proceed, detailed thin section and polished section petrographic work, and electron probe analysis as well as independent analytical studies were completed on core samples before any further samples were submitted for assay. Upon completion of this work, all core samples originally submitted to ALS-Chemex in Johannesburg were redirected and submitted to ALS Chemex lab in Vancouver, B.C. Additional check assays were performed at EcoTech Laboratory in Kamloops, B.C.

The Phase Two diamond drilling program has focused on testing the potential for expansion of the Central Zone as it remains open in almost all directions, exploring the Central Zone Corridor aggressively at 200 metre interval to the north towards the Bodi Area and initiating exploration through diamond drilling of the Eastern Structural Corridor where known down-hole radiometric anomalies occur. If any significant uranium radiometric signatures/concentrations are encountered as a result of this program, diamond drilling will immediately begin at 100x100 metre spacing to define the resource as soon as possible, if possible with the assistance of a second drill rig.

Karl Kottmeier, President of Rockgate, commented, "We are pleased with the progress and results from Falea to date, despite the substantial delays in the assay process. We have completed over 20,000 metres of drilling which clearly shows that Falea is a large and compelling uranium exploration project. Our Phase Two drill program is well underway and we expect to commence an independent 43-101 report and initial resource calculation in the near future. The preliminary reviews of the sandstone porosity in mineralized core, surrounded by mudstones, suggest that in situ leach recovery is a possibility and we will shortly be initiating studies to determine its suitability for use at Falea."

The Falea exploration permit covers 150 square kilometres of the Falea-North Guinea-Senegal basin, a Neoproterozoic sedimentary basin marked by significant radiometric anomalies. Rockgate Capital has earned a 60% interest in the Falea Uranium-Copper from Delta and is the operator of the project.

Mr. Lorne Warner, P. Geo, Director and VP Exploration, is the Qualified Person for the Company under NI 43-101.
