Halliday Lake

  • 100% Uravan, Cameco Corporation (Cameco) earning an interest pursuant to the Stewardson/Halliday Option Agreement [press release April 25, 2012]
  • Historic geophysical surveys consisting of electro-magnetic (EM), gravity and resistivity surveys
  • Historic drilling consists of five (5) reconnaissance drill holes. The best intersection graded 0.08% and 0.12% U3O8 over 0.1m at the unconformity in EL-10 and EL-12 respectively
  • In 2011 a surface geochemical programs (clay separates from soils and tree-cores) over the project identified highly-anomalous radiogenic 207Pb/206Pb isotopic ratios and other pathfinder elements, which supported an east-west EM conductive/magnetic low corridor
  • In 2012 an infill surface geochemical program (soils and tree-cores) was completed over the central and eastern portions of the project
  • Combined 2011/12 analytical results (clays and tree-cores) from the surface programs indicated good overall data quality and reproducibility (radiogenic 207Pb/206Pb isotopic ratios and other pathfinder elements) for the clay separates
  • In 2012 five (5) diamond drill-holes (HL-01, -02, -03, -05 and -06) totaling 4,836 meters drilled was complete
  • Drill-holes were positioned to test the potential occurrence of uranium mineralization at depth along a prominent, east-west trending electromagnetic (EM) geophysical conductor (Conductor A) corridor, which cross-cuts a prominent linear magnetic low, and supported by a concordant distribution of anomalous surface geochemical signatures
  • Key alteration components intersected in DDH HL-01 suggest a more advanced hydrothermal and structural systems potentially exists toward the untested western end of the Conductor A corridor. Positive surface geochemical anomalies (soils and trees) also highlight an area west of DDH HL-01 and EL-10 coincident with Conductor A.  Future drilling plans will focus in this prospective target area (see maps below)

  • In March 2013, Aurora Geosciences Ltd. (Aurora), in collaboration with Uravan and Cameco Corporation, conducted a 'test' EM ground geophysical survey over Conductor A, west of DDH HL-01 (see map below). The test survey was completed by Aurora using their extremely low frequency electromagnetic (ELF-EM) system (Link to technical report). The ELF-EM system is a ground-based geophysical technique/instrument that is easily transported and does not require cut lines. The system calculates the tilt angle (tipper) of the magnetic fields from 11 Hz to 1440 Hz and is designed to image resistivity from depths of 10 meters to 2 kilometers. 
  • The cumulative results of the technical data (geochemical, geophysical and structural interpretation) on the Halliday project is vectoring drilling toward an untested area west and south of drill-holes HL-01 and EL-10 and where the ELF-EM conductive trend is strongly supported by surface geochemical anomalies (map below). Further drilling in this area will be the basis of the Corporation's future programs.
