VANCOUVER, BRITISH COLUMBIA — (Marketwire) — 08/14/12 — Rockgate Capital Corp. (TSX: RGT) (the „Company“) is pleased to announce assay results from infill and step-out diamond drilling completed along and adjacent to the southeast-trending Plateau Edge Structure („PES“) and in the newly discovered Northeast Plateau Zone. Hosting high-grade uranium-silver-copper mineralization, the PES is a major mineralized structural zone within the North Zone at Rockgate-s 100% owned Falea Project. An update of mineral resources is planned for later this fall.
Highlights:
The PES infill drill program was designed to:
The Northeast Plateau step-out and exploration drill program has been successful in:
Plateau Edge Structure
The northwest-trending Plateau Edge Structure is a major mineralized structural zone within the North Zone Area, hosting elevated and thicker than deposit average uranium, silver, and copper mineralization. Silver and copper grades are significantly higher than other areas of the Falea deposits. PES is quite well-understood by virtue of the fact that much of the identified PES is drilled off to 25-metre drill hole spacing. Thus, most of the PES mineral resource is classified as Measured.
The 2012 diamond drilling at PES extended the 25-metre drill spacing to better define the margins of the „structure“, including trends in uranium, silver, and copper grades and thickness of mineralization. In general, grades and thickness are strong stepping to the east and west of the core of the trend, and remain stronger to the west. Table 2 highlights many of these results.
Northeast Plateau
The Northeast Plateau was discovered in November 2011 and was not included in the January 2012 Mineral Resource Estimate. On April 4th, 2012, Rockgate released results for the initial 16 diamond drill holes completed in late 2011. From January through March, Rockgate drilled off the new discovery to 50-metre drill spacing.
The Northeast Plateau is located proximal to high-grade mineralization in the PES and uranium mineralization is widespread. Highlights of this phase of drilling are presented in Table 3.
Northeast Exploration Program
Nineteen diamond drill holes stepped northeast and east of the Northeast Plateau and North Zone on a 200-metre spaced grid as part of a systematic assessment of the area. Drilling tested up to 650 metres north of the Northeast Plateau and 600 metres east of the North Zone. Drilling confirmed uranium and silver mineralization underlying an area of approximately 94 km2. Results for all 19 drill holes are listed in Appendix I.
2012 Diamond Drill Program
Rockgate-s H1 2012 drill program involved 4 diamond drills exploring several areas outside the current resource boundary.
Step-out drilling was focused on 3 main areas:
Drilling was suspended on August 1st due to the onset of intense seasonal rains.
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.
HQ-size core (63.5 mm diameter) was drilled at both PES and Northeast Plateau. Mineralized core was sawn in half and one half sawn into quarters. One quarter core was sent for assay, quarter retained as a permanent record, and half core was collected for pilot plant-scale metallurgical test work
