September 26, 2013 (Source: Marketwired) — Rockgate Capital Corp. (TSX:RGT) (the “Company”) is pleased to announce additional high-grade grade uranium-silver-copper intervals in the 880 Zone, located immediately 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 trends west-southwest extending 300+ metres.
  • DF-904 averages 0.59% U3O8 and 45.7 g/t Ag over 2.7 metres.
  • DF-921 averages 0.12% U3O8 and 86.3 g/t Ag over 3.0 metres.
  • Located west of the Road Fault, south of the west half of the North Zone.
  • Mineralization remains open in several directions.

The H1 2013 Campaign comprised 19 diamond drill holes totalling 5,910 metres. Drilling focused on the delineating the recently-discovered 880 Zone. Of the 19 drill holes collared, 14 are located in and around the 880 Zone and 5 holes tested basin stratigraphy and structure immediately north of the Central Zone. The 880 Zone mineralization has not yet been included in mineral resource estimates.

880 Zone

14 diamond drill holes were completed over a 500 metre strike length of the 880 Zone, from the Road Fault in the east, across the interpreted 880 Fault to the west. Drilling confirmed the trend of high-grade mineralization between DF-760 at the Road Fault and DF-902, approximately 315 metres to the southwest. Step-out drill holes 100 metres further west included DF-907 to DF-911, and intersected anomalous uranium and silver mineralization. However, the high-grade 880 Zone trend appears to have been displaced by the northwest-trending 880 Fault. A study of the structural, stratigraphic and geochemical patterns of the entire deposit area has been initiated to identify further targets on the 880 Zone and elsewhere.

Central Zone

Five diamond drill holes tested the northwest and northeast structural corridors immediately north of the Central Zone. Two holes were completed adjacent to and east of the Road Fault to determine if the KS sandstone and KI mudstone in the area were pathways for mineralizing fluids from the North Zone along the margin of the Road Fault. Similarly, 3 more holes tested a structural corridor immediately east of a central paleo-topographic high. All 5 drill holes were weakly anomalous in uranium and locally silver.

The stratigraphy, structure, and geochemistry of the area between the Central and North Zones will be studied utilizing existing airborne magnetics, VTEM, and radiometric data, and geological and geochemical data from drill holes. Particular emphasis will be placed on better defining the architecture of the Falea Basin in the 50 metres above the Birimian unconformity where all uranium mineralization is localized.

2013 Program

  • 14 diamond drill holes and 4,563 metres were completed in 880 Zone for resource delineation.
  • 5 diamond drill holes and 1,347 metres were completed on Central Zone basin definition.
  • A study of structural, stratigraphic and alteration patterns of the entire deposit area has been initiated.
  • DRA Group is conducting a Pre-Feasibility Study (PFS) on the Falea Project.
  • A 10-hole program of water-well drilling was completed to help assess the hydro-geological characteristics of the potential mine site.

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 Minerals 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.
