"Preliminary benchtop leach tests of uranium-rich, oxidised ore samples from drillhole KKRC0622 (a 6 metre sample composite) completed by Bureau Veritas laboratory in Adelaide during 2024 showed rapid leaching of uranium 1 and copper with potential for ion exchange recovery of the metals from solution. Mineralogical studies show uranium is present as coffinite 2 and uraninite."

1 Preliminary leach tests conducted during 2024 by Bureau Veritas metallurgical laboratory in Adelaide conducted on a sample composite from drillhole KKRC0622 that averaged 1,368 ppm 3 uranium. [from page 6 of the 31 July 2024 Havilah ASX Quarterly Activity Report]
2 Coffinite is a uranium-bearing silicate mineral. It occurs as black incrustations, dark to pale-brown. The hardness of coffinite is between 5 and 6 on the Mohs scale. For fans of the game show Jeopardy, the mineral was named for American geologist Reuben Clare Coffin (1886–1972).
3 1,000 ppm = 0.1% = 2.2 lbs/tonne U3O8.
