Rockgate Intersects 1.0 Metre of 3.05% U3O8 With 201.0 g/t Ag and 4.0 Metres of 0.73% U3O8 With 183.0g/t Ag in Step Out Drilling at Falea

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 4, 2010) - Rockgate Capital Corp. (TSX VENTURE:RGT) (the "Company") is pleased to report assay results from diamond drill holes DF-178 to DF-199 (22 holes) completed in the North Zone Area. Of particular significance are holes DF-190-192,195-197,199 (8 holes) and previously reported hole DF-175 which all contain higher grade uranium mineralization associated to a recently discovered north-west trending structure now called the Plateau Edge Structure ("PES").

Highlights of newly defined Plateau Edge Structure:

  • Extends current North Zone Resource Area by over 400 Metres
  • Open along strike
  • Average width 130 metres
  • Average thickness 3.63 metres
  • Average grade of 0.56% U308
  • Extends North Zone to within 200 m of plateau edge

The following table lists the eight diamond drill holes within PES Area high-grade mineralization.

Estimated true widths are between 92-100% of core length for all twenty-two holes reported. For a detailed map of all hole locations please see www.rockgatecapital.com/news.

The mineralization is contained in the sandstone horizon and in the lower conglomerate unit immediately above the unconformity along the central core of the structure. There is also potential for additional uranium mineralization beneath unconformity.

The newly defined PES area has the potential to substantially increase the number of pounds and increase the overall grade of the current NI 43-101 Inferred, uncapped resource on Falea, currently totalling 20,252,000 lbs U308 and 31,600,000 ounces of silver in 10,840,000 tonnes using a 0.03% U308 cut-off. Included in this resource calculation is a small component of Indicated resources.

Rockgate VP Exploration Lorne Warner commented, "These results have significantly and positively impacted both the strike length and the average grade of U308, at the North Zone. The PES remains open, as do all mineralized zones at Falea. We currently have two drill rigs working to complete the remaining 40 holes of the winter-spring 2010 drill program, prior to commencing a new resource calculation. I am greatly encouraged with the development of the known zones at Falea and am looking forward to exploring the 90+% of the property that to date remains untested."

Infill Drilling

Seven diamond drill holes were completed inside the current North Zone resource area. Holes DF-178-180 are located east of the Road Fault on 100 metre centres. Holes DF-185-188 are located in the south-eastern portion of the resource area testing an area of previous uranium and/or higher-grade silver intercepts. Assay results from these holes are as follows:

Hole Name From (m) To (m) Core Length (m) U308% XRF Ag (g/tonne) Cu % Comments
DF-178 205.00 208.00 3.0 0.09 126.7 0.24

Step-out Drilling

The following six (6) step-out holes were drilled at three separate areas, all located outside of the North Zone resource area.

Holes 183-184 are 100 metre step outs located immediately east of the Road Fault on the south side of the North Zone resource area.

Hole Name From (m) To (m) Core Length (m) U308% XRF Ag (g/tonne) Cu % Comments
DF-183 upper 229.00 231.00 2.0 0.02 1.7 0.01 100 m step out

including 202.00 204.00 2.0 0.07 2.5 0.01  

Hole 189 is a 200 metre step-out, located south of the north east corner of the North Zone resource area.

DF-189 220.00 221.00 1.0 0.02 1.2 0.12 200 m step-out

Holes 193, 194 and 198 are 100 metre step-outs located on the eastern and western flanks of the PES.

DF-193 204.00 205.00 1.0 0.03 4.7 0.18 100 m step out
DF-194 198.00 199.00 1.0 0.04 3.1 0.04 100 m step out
DF-198 191.00 192.00 1.0 0.01 1.7 0.16 100 m step out

The current drilling program is providing further evidence the property has good potential to host high-grade mineralization in feeder structures beneath the Kania sandstones along inferred growth faults. 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.
