Rockgate Expands High-Grade Plateau Edge Structure, Falea Uranium-Silver-Copper Project, Mali; Including 1m @ 2.01% U3O8, 420 g/t Ag and 1.73% Cu07:30 EDT Thursday, April 26, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 26, 2012) -Rockgate Capital Corp. (TSX:RGT) (the "Company") is pleased to announce assay results from twenty two infill and step-out diamond drill holes completed along five sections across the northern portion of the northwest-trending Plateau Edge Structure (PES). The PES is a major mineralized structural zone within the North Zone at Rockgate's 100% owned Falea Project. Drill holes and sections are spaced every 25 metres. Highlights of the program are presented in Table 1.Table 1: Drill HighlightsSection NorthHole NameFrom (m)To (m)Length (m)U3O8% XRFAg (g/tonne)Cu %1 360 600NDF-442197.2200.23.000.90182.31.00incl198.2199.21.002.01420.01.73DF-445194.0197.02.910.10368.30.431 360 575NDF-455195.1198.02.900.32236.70.40DF-458197.1204.17.000.2255.60.451 360 550NDF-470205.3212.06.700.1820.70.221 360 525NDF-474197.8200.62.800.08184.90.361 360 500NDF-476205.8216.010.200.1610.20.38All reported intervals are true lengths.The PES step-out drill program was designed to:Extend the limits of the highest grade resource area at Falea. Better understand the sedimentology and structural geology controlling PES. Provide detailed resource modelling for ongoing mine planning. PES has been identified as a resource likely to be exploited early in any potential mine plan. Upgrade Indicated resources to Measured category. Drilling stepped out to both the west and east of the identified high-grade mineralization, extending those high grades, particularly high silver values, and above average thicknesses. In particular, intersections to the west of PES indicate high grades extend at least 100 metres west of the boundary of the current measured resource. The "measured resource" being that defined in the Company's independent NI 43-101 resource calculation announced January 16, 2012. Step-out drilling along the entire PES continues to the east and south.Section 1 360 600 NFour diamond drill holes, DF-442, DF-445, DF-447, and DF-450, stretched from the western boundary of the "measured resource" almost 200 metres to the west. Just inside the boundary, DF-442 intersected uranium, silver, and copper grades over 3.0 metres that are far above deposit averages. (Tables 1 & 2) Fifty metres west of DF-442, DF-445 intersected 0.10% U3O8, 368 g/t Ag, and 0.43% Cu over 2.91 metres true thickness. Silver grades continue high in DF-447, at 115.5 g/t over 3.0 metres, another 50 metres to the west. Stepping another 100 metres west, DF-450 intersected 0.52% U3O8 and 40.0 g/t Ag over 1.2 metres.Table 2: Section 1 360 600NHole NameFrom (m)To (m)Length (m)U3O8% XRFAg (g/tonne)Cu %DF-450214.718.104.22.16840.00.11DF-447188.5191.53.000.09115.50.31incl188.5189.51.000.21328.00.75DF-445194.0197.02.910.10368.30.43incl195.0197.01.940.12331.00.29DF-442197.2200.23.000.90182.31.00incl198.2199.21.002.01420.01.73DF-485201.8202.30.500.0471.01.46DF-487194.9198.03.100.0386.30.10incl194.9195.70.800.04325.00.34Section 1 360 575 NTwo diamond drill holes, DF-452 and DF-455, drilled at the western boundary of the "measured resource", intersected strong uranium, silver, and copper grades. (Table 3) At the eastern boundary, DF-458 and DF-460 intersected 7.0 metres and 6.3 metres of high-grade mineralization. Stepping at 25-metre intervals to the east, thicknesses are good with lower uranium and increasing silver grades. In Table 2, drill holes are listed from west to east.Table 3: Section 1 360 575NHole NameFrom (m)To (m)Length (m)U3O8% XRFAg (g/tonne)Cu %DF-452197.1200.73.600.2750.70.37incl198.0198.90.900.3942.00.40DF-455195.1198.02.900.32236.70.40DF-458197.1204.17.000.2255.60.45incl201.6204.12.500.4054.40.80and202.5203.51.000.6652.00.89DF-460194.8201.16.300.1220.70.17incl199.922.214.171.12444.00.58DF-463195.0202.47.400.0619.70.28incl197.0198.01.000.1265.50.47DF-465198.2202.03.760.0532.60.24incl201.4202.00.590.1678.01.04DF-468201.2205.44.070.0876.00.09incl201.2201.70.470.09635.00.02Section 1 360 550 NFour diamond drill holes were completed on the west side of section 1 360 550N. The westernmost hole, DF-492 intersected high grades including 262 g/t Ag over 1.9 metres. Fifty metres east, DF-490 intersected 0.09% U3O8 and 65.7 g/t Ag over 2.9 metres. 50 metres east, DF-472 intersected 0.7 metres of mineralization within 50 metres of the "measured resource" boundary. At the boundary, DF-470 intersected 6.7 metres of mineralization, suggesting local variability in both grade and thickness away from the core of the PES.Table 4: Section 1 360 550NHole NameFrom (m)To (m)Length (m)U3O8% XRFAg (g/tonne)Cu %DF-492194.0195.91.900.18262.00.63DF-490196.6199.52.900.0965.70.22incl197.1126.96.36.19961.00.29DF-472198.6199.30.700.0648.00.49DF-470205.3212.06.700.1820.70.22incl207.3209.11.800.4225.10.31and210.9212.01.100.2960.00.26Section 1 360 525 NOnly one diamond drill hole was completed on section 1 360 525N.

Drilling has resumed as announced April 25th after a shutdown during the short period of political instability following the coup d'etat in Mali on March 22, 2012.Northeast Plateau - to continue to expand and define this new area of mineralization. Bodi Area - to confirm and expand near-surface mineralization north of the Falea plateau with the aim of identifying potential open pit resources and access to underground at North Zone. Drilling is planned on various targets including the southern step-out and Northwest Extension of North Zone, Central Zone step-outs, and the Bala area. Also, a drill will be assigned to drill PQ holes around the deposits to collect samples for comminution and ongoing metallurgical test work. Christopher J. Wild, P.Eng., Project Manager for Falea, is the Qualified Person for the Company under NI 43-101. All core samples are cut in half on site and sent to ALS-Chemex in Bamako for direct shipment to ALS-Chemex in Johannesburg, South Africa, for ICP-MS and XRF analysis. The Company inserts a standard, blank and requests a duplicate sample be run in every batch of 20 samples. In addition, the lab inserts in-house blanks, standards, and duplicates with each shipment. Data that falls outside the control limits are checked and repeated as necessary.Please visit our website at www.rockgatecapital.com.ON BEHALF OF THE BOARD OF DIRECTORS OF ROCKGATE CAPITAL CORP.Karl Kottmeier, PresidentTo view the map accompanying this press release, please click on the following link: http://media3.marketwire.com/docs/rgt426.pdfFOR FURTHER INFORMATION PLEASE CONTACT: Karl KottmeierRockgate Capital Corp.President604-678-8941ORKirk GamleyRockgate Capital Corp.VP Corporate Development604-678-8941604-689-7442 (FAX)www.rockgatecapital.comNeither Toronto Stock Exchange nor its Regulation Services Provider (as that term is defined in the policies of the Exchange) accepts responsibility for the adequacy or accuracy of this release.
