Rockgate Intersects 0.23% U3O8 and 896.0 g/t Silver over 2 Metres at North Zone, Falea Uranium-Silver-Copper Project, Mali

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 8, 2011) - Rockgate Capital Corp. (TSX:RGT) (the "Company") is pleased to announce assay results from 12 diamond drill holes, part of an infill and step-out drill program on the North Zone. High-grade uranium and silver mineralization has been extended along the west (down) block of the north-trending Road Fault, which divides the North Zone into east and west blocks. New interpretations of the likely controls to mineralization suggest a strong west-southwest structure and subsidiary northwest structures. Highlights of this stage of the program are presented in Table 1.

Road Fault West

The drill holes reported herein are all located between 50 metres and 250 metres west of the north-trending Road Fault. The Road Fault is a reverse fault with approximately 60 metres displacement – west side down – but no significant strike-slip displacement. The fault appears to divide the North Zone into relatively equal area blocks, one east and one west.

These 12 HQ-size infill diamond holes were drilled to:

  1. Upgrade the existing "inferred" resource to an "indicated" category
  2. Better define resource boundaries
  3. Better define structural controls to mineralization
  4. Provide samples for additional metallurgical test work

Results confirm a strong west-southwest control to mineralization. Along this structure, high-grade uranium and silver grades are located in the centre; DF-371, DF-381, DF-388, DF-389, DF-391, DF-393, and DF-394 are located in a 150-metre wide high-grade corridor, flanked by moderate to high-grades in DF-374, DF-380, and DF- 396 to the north. DF-376 and DF-378 lie to the north of a relatively sharp grade boundary. A complete summary of results is found in Table 2.

Previous drilling on 25-metre centres to the east and west of the reported drill holes highlight very high silver grades in the centre of the west-southwest trending structure. To the south, DF-335 extends those high-grades to the previously interpreted southern boundary, opening up that area to some expansion. Interpreted northwest- trending structural controls appear to be less dominant than previously thought but drilling is limited north of the newly interpreted west-southwest structure. However, significant intersections to the north suggest a second west-southwest control or intersecting northwest and west trending structures. Further drilling is planned for both the northern and southern sections of the west half of the North Zone.

2011 Drill Program to Date

Rockgate's 2011 drill program has focused on the following goals:

  • Infill drilling to upgrade the identified resources within the North Zone. Equally important, increasing the drill density greatly aids in interpreting controls to mineralization, especially high-grade trends, which will direct future drilling.
  • Step-out drilling to extend identified mineralized trends outside the currently defined resource boundaries. At North Zone, west-southwest and east-northeast mineralized trends continue to be tested. Step-out drilling is also planned for Central Zone and Bodi Zone. The latter represents a significant near- surface, bulk tonnage target.
  • Exploration drilling targeting the Bodi area to the south, Kania and East Zones to the east, and areas to the west. Some drilling has been completed at Kania and to the west.
  • To date, less than 10 percent of area hosting down-hole radiometric anomalies has been drill tested.

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.
