VANCOUVER, BRITISH COLUMBIA -- Rockgate Capital Corp. (TSX:RGT) (the "Company") is pleased to announce assay results from 14 infill diamond drill holes completed along three sections across the southern portion of the northwest-trending Plateau Edge Structure (PES). The PES is a major mineralized structural zone within the North Zone Area at Rockgate's 100% owned Falea Project. Drill holes and sections are spaced every 25 metres. All 14 drill holes intersected high-grade uranium-silver over widths ranging up to 8 metres with 13 of the 14 intersecting widths greater than 5 metres. Highlights of these results are presented in Table 1.

Section 1 360 475 N (Table 2) represents the southernmost detailed drilling across 125 metres width of the PES. DF-140 had previously identified high-grade Ag mineralization across a relatively long interval of Kania Sandstone (see Rockgate News Release – October 1, 2008). DF-285 and DF-286 returned better grades than DF-140 over increased widths. However, holes DF-275 and DF-288, located on the interpreted eastern and western margins of the PES, also returned strong U3O8 and Ag grades. Drill holes are listed from east to west in Table 2.

Section 1 360 500 N steps 25 metres to the north, targeting 3 holes into the centre of the PES. Grades and thicknesses of mineralization in all 3 holes are typical of the central PES (Table 3) and demonstrate the consistency in both grade and thickness across that part of the structure. Drill holes are listed from east to west in Table 3. Additional drill holes are planned stepping out both to the east and west along section 1 360 500 N.

Section 1 360 525 N steps another 25 metres to the north and consists of 6 drill holes across the PES. Drill holes are again listed from east to west in Table 4. Results demonstrate that silver grades remain strong in the eastern and westernmost drill holes suggesting there is room to expand the zone. When all 3 sections are viewed collectively, it appears that there may be a subtle east to northeast-trending control to mineralization. Where main northwest-trending structures such as the PES intersect these east-northeast structures, mineralization appears to be high-grade across significant widths.

Core lengths are estimated to be 100 percent of true width.
2011 Drill Program
The Company is currently conducting an extensive program of diamond drilling at Falea with 3 components.
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.
