EL 29898 Partial relinquishment report 15 August 2002 to 14 August 2014

Abstract

The exploration work undertaken by LCR for the sub-blocks to be relinquished has included an airborne magnetics and radiometrics survey which was undertaken in 2005 using a Cessna 210 fixed wing survey aircraft. The survey was flown at 100m NS line spacing with 1000m spacing EW tie lines, at a nominated sensor height of 60m. The survey covered an approximate area of 1,950km2, totalling 21,504 line kilometres. On-ground exploration has comprised collection of regional stream sediment samples from 54 locations in 2007. Samples were submitted for ME-MS41 and Au-CN12 laboratory analysis. Results revealed the highest uranium concentration of 2.78ppm in sample 1048A. The highest gold concentration was 7.5ppb from sample 1043B. In 2009, a combination of on-ground scintillometer and soil sampling was undertaken over two separate NW trending faults (Target areas 10 and 11) and were considered favourable for uranium mineralisation. The scintillometer work was undertaken at 25m north-south and 50m east-west intervals. A total of 2,405 scintillometer readings were taken, with the highest uranium reading being 12.3ppm at sample point 837 within Target 10. Following the scintillometer work, soil sampling was undertaken over the two target areas. In total, 81 soil samples, at the same spacing as the initial scintillometer points, were taken and submitted for ME-ICP61 laboratory analysis. The laboratory analysis did not reveal any elevated uranium concentrations with all of them falling below the minimum detectable level of 10ppm. It was decided to relinquish these sub-blocks so that LCR can concentrate exploration on the more prospective areas of the tenement; and to enable a more effective and efficient approach for on-ground work.
