Rockgate Discovers New 880 Zone in Southeast Block of North Zone, Falea Uranium-Silver-Copper Project, Mali
April 9, 2013 (Source: Marketwire) Vancouver, BC — Rockgate Capital Corp. (TSX:RGT) (the “Company”) is pleased to announce the discovery of a new trend of high-grade grade uranium-silver-copper mineralization located to the southwest of the North Zone. The 880 Zone was identified during the Fall 2012 drill campaign. Important points regarding 880 Zone include:
- High-grade uranium-silver-copper mineralization trending west-southwest extending 300+ metres
- DF-880 averages 0.21% U3O8 and 246 g/t Ag over 3.35 metres.
- DF-902 averages 0.17% U3O8 and 39.5 g/t Ag over 3.35 metres.
- Previously released DF-760 averages 1.03% U3O8 and 88.7 g/t Ag over 2.0 metres.
- Located west of the Road Fault, south of the west half of the North Zone.
- Continuation of the east-west South Block structure east of the Road Fault.
- Open along strike to west and southwest.
The Fall 2012 Campaign comprised 66 diamond drill holes totalling 15,936 metres. Drilling focused on several areas surrounding the North Zone including the Southwest Block, South Block, West and Northwest Extensions, and the Bodi Area with the goal of converting Inferred mineral resources to an Indicated category. Of the 66 drill holes collared, 45 are located in and around the North Zone and 21 in the Bodi Area.
None of the Fall 2012 drill holes are included in the recently completed Mineral Resource Update (see Rockgate News Release December 4, 2012).

The 880 Zone was discovered through systematic drilling of the Southwest Block. Thirteen drill holes were collared in the Southwest Block, of which one was lost due to bad ground conditions. Ten holes were completed on a100-metre grid spacing, including 3 drilled across the Road Fault and 5 along a north-south fence approximately 400 metres west of the Road Fault. DF-880 is located in the middle hole in the fence. DF-892 and DF-897 were drilled west of DF-880, anticipating a westerly trend to mineralization. DF-902, the last hole of the North Zone program, intersected strong uranium-silver-copper mineralization 70 metres southwest of DF-880, in line with DF-760, over 300 metres to the northeast.
Drilling continued along the southern extension of the South Block, east of the Road Fault. Fifteen diamond drill holes were completed at 50 and 100-metre step-outs. DF-844, DF-849, and DF-868 form a fence of drill holes 50 metres south of the previous limit of drilling, returning variable results. Drill holes stepping further south did not intersect further significant mineralization. Similarly, further east, DF-841 marks the southern limit of significant mineralization at this time.
Infill diamond drilling in the North Zone Deep (west of the Road Fault) was successful in extending variable mineralization in areas of inferred mineral resources (see Table 3). Twelve infill drill holes were completed in the Western Extension and closer to the Road Fault. Four drill holes were completed as part of a significant step-out to the northwest with two holes intersecting uranium mineralization.
Christopher J. Wild, P.Eng., Project Manager for Falea, is the Qualified Person for the Company under NI 43-101. All core samples are halved or quartered 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.
