Ownership: 100% Aura
Aura’s wholly owned Kallsedet Project covers 147km2 near Kallsedet, close to the Norwegian border. Kallsedet was explored by the Swedish government in the 1970s, when they found good grades of uranium, although at lesser thicknesses than at Häggån.
Aura anticipates that a large proportion of its permits are underlain by the Alum Shale. In addition, fieldwork in the area has identified a number of radiometrically anomalous zones corresponding with the position of the Alum Shale. The company is highly encouraged by the consistent values obtained from surface rock-chip sampling. Research has shown that parts of the shale are relatively high grade.
For example, one sample collected by the Swedish Geological Survey contained 304 ppm U3O8, and one sample collected by Aura contained 233 ppm U3O8. In addition, 19 out of 81 samples contained greater than 100ppm U3O8, despite surface leaching. Surface radioactivity is at a level above that found in the Storsjön Project area. The shale contains no calcite veining, which may enhance metal extraction.
Results included one drill hole that intersected 60m at 144 ppm U3O8 including 6m at 224 ppm U3O8 confirming the potential, for thick, higher grade zones of mineralisation within the licence areas.
