The Haggan project forms part of a large uranium field in Central Sweden, containing uranium along with molybdenum, nickel, vanadium and zinc in black shales.

The shales form a near-continuous sheet throughout the part of the project that was drilled earlier, with thicknesses ranging between 20m and more than 250m.

Aura Energy’s managing director Bob Beeson said that the resource upgrade demonstrates the vast size of the uranium mineralisation in the Haggan project and that the firm has only placed a portion into resources till date.

"The mineralisation occurs as a thick, flat lying sheet of multi-metal mineralisation and further major resource upgrades are anticipated," Beeson said.
