Delta Exploration Inc.: Diamond Drilling Intersects 0.31% U3O8 and 1,652.3 g/tonne Silver Over 3.3 Metres in North Zone, Falea Uranium Project, Mali

Delta Exploration Inc. (\"Delta\") (TSX VENTURE:DEV) is pleased to report some of the highest grades of uranium encountered to date as well as the discovery of disseminated native silver mineralization within the North Zone of the Falea Uranium Project, highlighted by hole DF-084 which returned 0.31% U3O8 and 1,502.1 grams/tonne silver.

(i) Results from DF-070 were first released Feb 29, 2008.
    DF-070 results have been re-released herein to provide
    continuity between releases of the substantial silver
    results being discovered at North Zone. All hole
    lengths are equal to true width except hole 81, which
    has an estimated true width of 1.38 metres.

The North Zone was first discovered in November 2007 and is now known to contain uranium mineralization over a strike length of 1,500 metres by 400 metre width. High-grade silver mineralization, based on assays received to date and observed native silver in drill cores (with assay results pending) is occurring along the southern edge of the North Zone over a strike length 1,400 metres and widths of up to 190 metres. Drill hole DF-081 is located on the north flank of the North Zone indicating the potential of a second high-grade silver zone contained within the North Zone.

\"We are really pleased with these results from the North Zone. We have focused much of our work in the past months on defining the size potential of the North Zone. Not only has the North Zone increased in strike length and width but the presence of such high grades of silver in addition to the excellent continuity of the uranium results may substantially impact the economic potential of the Falea project as a whole,\" commented Rockgate president, Karl Kottmeier.

New geological interpretations on the relationship of mineralization to open rolls in the known three regional structural corridors has indicated the potential for additional uranium zones to occur in each one of the three known corridors. Since October 2007, Rockgate has completed over 20,000 metres of diamond drilling in 84 holes in the North Zone and has expanded the current diamond drilling program.

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 this Press Release under NI 43-101 and is currently on site at Falea. All core samples are sawed in half and sent to Bamako where ALS prepares the samples with pulps then shipped to EcoTech Laboratories in Kamloops B.C. for ICP-MS analysis and ALS in Vancouver for XRF analysis for uranium. Rockgate inserts a standard blank and requests a duplicate sample in every batch of 20 samples.
