Diamond Drilling Confirming High Grade Mineralization at North Zone, Falea U-Ag-Cu Project, Mali-West Africa

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 8, 2009) - Rockgate Capital Corp. (TSX VENTURE:RGT) (the "Company") is pleased to report uranium, silver, and copper results received from 8 diamond drill holes completed in the North Zone of the Falea Project, located in Mali, West Africa. The summer campaign focused on infill and step out drilling of the south-east area of the North Zone.



Highlights of the program include:

Infill Hole
-----------
DF-168 0.18 % U3O8 2,645 g/tonne Silver over 7.0 meters

Step out Hole
-------------
DF-169 0.53 % U3O8 307 g/tonne Silver over 10.0 meters


Infill holes DF-165 to DF-168 tested mineralization in the North Zone, within the area of the Golder Associates resource estimate reported in May, 2009. These infill holes were drilled at 50 meter centers around hole DF-145, reported October 01, 2008 which contains 0.04% U3O8, 668.7 g/tonne Ag over
7.19 metres, including 0.08% U3O8, 1197.6 g/tonne Ag over 3.60 metres.

The Golder resource estimate outlined Indicated Resources of 871,000 pounds U3O8 and 1,116,000 ounces of silver for an average grade of 0.07% U3O8 and 61grams/tonne silver. The Inferred Resources total 19,381,000 pounds of U3O8 and 30,484,000 ounces of silver with an average grade of 0.09% U3O8 and 92.0 grams/tonne silver. The calculation is based on uncapped values using a cut-off grade of 0.03% U3O8.

DF-165 tested the Kania sandstone 50 meters north of DF-145, the favourable sandstone unit in this location is highly silicified which locally restricts the unit's ability to host higher concentrations of uranium. DF-166 tested the Kania sandstone 50 meters west of DF-145, and the sandstones were oxidized with minimal silicification resulting in good uranium and silver mineralization. DF-167 was drilled between DF-145 and DF-146 and had good uranium and silver mineralization over only 1.0 metres due to sporadic silicification of the sandstones. DF-168 was drilled 50 meters east of DF-145, and encountered good uranium mineralization and the highest grade silver mineralization found on the property so far, at 1.15 % U3O8 and 1.79 % silver over 1.00 meters.

North Zone Exploration Drilling

Four exploration holes were drilled on the south side of the North Zone over the course of this program. Two other holes were abandoned before reaching their target. The holes were drilled on a 50 by 50 meter grid between, and to the east of, DF-146 and DF-147. Holes DF-146 and DF-147 were completed in the spring of 2008.

Reported widths are estimated to be true width. Holes DF-171 and DF-176 were abandoned before reaching target depths due to technical problems with the reverse circulation drill. DF-176 was completed by hole DF-172.

Hole DF-169 was drilled midway between DF-146 and DF-147, at the edge of the area covered by the resource estimate. It encountered 0.53% U3O8 over 10 metres, including 2.00% U3O8 over 2.00 metres, as well as excellent silver mineralization. DF-170 was drilled 50 meters east of DF-169 and encountered good uranium and minor silver mineralization over 6 meters within the Kania sandstone. DF-172 was drilled 100 meters east of DF-147 and encountered only weak uranium and silver mineralization. DF-177, drilled 50 meters east of DF-147 (midway between DF-147 and DF-172) encountered good uranium mineralization over 9.00 meters, including 0.16% U3O8 over 1 meter.

Closing Notes

Final assay results from exploration holes DF-173 to DF-175 completed 400 metres north of the defined North Zone resource area are still pending. The next phase of drilling is anticipated to total at least 15,000 metres, commencing in October and continuing into the middle of 2010. The program will focus on infill and step out drilling around the North Zone and will also begin to evaluate the numerous down-hole radiometric anomalies encountered by Areva's (previously Cogema) exploration of the property in the 1970's which have yet to be tested by Rockgate. The Falea exploration permit covers 150 square kilometres of the Falea - North Guinea - Senegal basin, a Neoproterozoic sedimentary basin marked by significant radiometric anomalies.
