Rockgate Capital Corp.: Diamond Drilling Confirming High Grade Mineralization at North Zone, Falea U-Ag-Cu Project, Mali-West Africa

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 1, 2009) - Rockgate Capital Corp. (TSX VENTURE:RGT) (the "Company") is pleased to report uranium, silver, and copper results received from 16 diamond drill holes completed in the spring program in the North and East Zones of the Falea Project, located in Mali, West Africa.

Highlights include:



DF-160 0.29% U3O8, 28.5 g/t Ag, 0.17% Cu over 4.0 metres
0.30% U3O8, 815 g/t Ag, 0.26% Cu over 5.0 metres

DF-162 0.34% U3O8, 236 g/t Ag, 0.17% Cu over 4.0 metres
0.53% U3O8, 96.6 g/t Ag, 0.38% Cu over 5.0 metres


The 2009 spring campaign focused on three areas: North Zone infill, the eastern extension of the North Zone, and the East Zone. North Zone infill drilling is contained within the area of the first resource estimate, announced May 15, 2009. The resource estimate for Falea, completed by Golder Associates, outlined 871,000 pounds of U3O8 and 1,116,000 ounces of Ag in 572,000 tonnes grading 0.069% U3O8 and 61 g/t Ag in Indicated resources and 19,381,000 pounds of U3O8 and 30,484,000 ounces of Ag in 10,270,000 tonnes grading 0.086% U3O8 and 92 g/t Ag of Inferred resources at a cut-off grade of 0.03% U3O8 and uncapped U3O8 and Ag grades.

Drilling along the eastern extension stepped east and southeast of the resource area. Two holes were drilled at East Zone to extend mineralization discovered in 2008. Hole locations were based largely on results of an IP survey completed in January and February, 2009 over the eastern section of the North Zone.

Rockgate has also completed a second phase of diamond drilling totalling 13 holes with final assay results still pending. The second program consisted of additional infill drilling within the North Zone resource area as well as step-out holes designed to test the extension of the North Zone. Uranium mineralization is known to occur at the Bodi Zone, located approximately 1.2 kilometres north of the current North Zone resource area and both zones remain open in several directions. Exploration diamond drill holes were completed between the North and Bodi zones, based on the recent identification of north-northwest trends bearing higher grade mineralization. One of the exploration holes returned the highest scintillometer readings recorded to date by Rockgate on the entire Falea project area and as a result this area will become a high priority in the next phase of drilling.

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. An exploratory drill program will also begin to test the 30 square kilometres of the Falea license where drilling by Areva (previously Cogema) identified down-hole radiometric anomalies.

Additional metallurgical studies will be initiated upon receipt of all assays from the spring 2009 drill programs.

North Zone Infill Drilling

Six holes tested mineralization within the area of the resource estimate. One other hole (DF-161) was abandoned before reaching the target Kania sandstone.

All reported lengths are true widths, except for DF-160 and DF-162 where true widths are estimated to be 97% of the reported lengths.

DF-153 tested the eastern side of the resource area. DF-157 and DF-158 targeted the middle of the upper plate of the North Zone while DF-159 targeted the lower plate of the north zone at the northern edge of the resource area.

DF-160 and DF-162 were drilled between DF-086 and DF-127, and were designed to cross the Road Fault, encountering both the upper and lower plates of the Kania Sandstones. Excellent results were obtained from both holes.

North Zone Exploration Drilling

Seven exploration holes were drilled over the course of this program. The first four were drilled on a 200 x 100 metre grid on the eastern edge of the north zone, to further define and track the mineralization. The remaining three holes tested anomalies defined by a High Resolution Induced Polarization (HiRIP) survey completed by Terratec Geophysical Services in February 2009.

Holes DF-149, DF-150, DF-151 and DF-152 were drilled on a 200 x 100 metre grid to the east of the resource area and were designed to track mineralization east of the currently defined North Zone mineralization. Generally, mineralization is confined to the Kania Sandstone, with lesser mineralization in the underlying Kania mudstone and volcaniclastics.

Holes DF-154, DF-155 and DF-156 were drilled to the southeast of the North Zone based on the results of the HiRIP survey conducted over the North Zone. Drill results suggest that IP surveys are of limited use in defining mineralization at depth.

East Zone Exploration Drilling

The East Zone, located approximately 3 kilometres east of the Central Zone, was discovered in the spring of 2008 when three holes (DF-121, DF-123 and DF-124) encountered significant uranium mineralization. Two holes were drilled to better determine the orientation and controls of that mineralization.

True widths are estimated at 99% and 91% of the reported lengths for DF-163 and DF-164, respectively.

In the East Zone, mineralization is confined to the Kania Sandstone, with minor mineralization noted in units immediately adjacent to the Kania. DF-163 targeted the Kania 100 metres north of DF-123, and DF-164 targeted the Kania 200 metres north of DF-123. The East Zone remains open in all directions.

Closing Notes

Lorne Warner, P. Geo, VP Exploration for Rockgate, comments, "The next drill program may be our most exciting yet as we continue to improve our understanding of the controls to mineralization. Recent drilling suggests the potential for higher grade mineralization near the inferred north north-west trending structures and beneath the sandstone unit that hosts all of the mineralization to date. Testing these structures beneath the sandstone unit will be important once their geometry is understood."

The Falea exploration permit covers 150 square kilometres of the Falea - North Guinea - Senegal basin, a Neoproterozoic sedimentary basin marked by significant radiometric anomalies.

Mr. Lorne Warner, P. Geo, Director and VP Exploration, is the Qualified Person for the Company under NI 43-101. All core samples are sawed in half on site and sent to ALS-Chemex in Bamako for sample preparation. Pulps are then sent 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.
