Pivotal information from 2nd in situ bench test10 Dec 2024 08:36
Cobra is delighted to announce it has demonstrated exceptional permeability through a second bench scale in situ recovery ("ISR") test from a section of core from its Boland Project.
Permeability is a critical enabler of ISR, and the rates achieved in this test bode well for future productivity
Permeability of mineralisation is a key productivity driver of ISR that can influence critical cost factors such as acid consumption, wellfield design and metal recovery
The second bench scale ISR study achieved the following results:
121 pore volumes per day or 24.3 metres per day at 5.5 bar pressure
43 pore volumes per day or 8.6 metres per day at 2.5 bar pressure
****As a result, the ISR bench scale study has been completed in only 24 hours, compared to the 150 days of the first study***
To me, the huge increase in permeability between the first and second bench tests is the trigger that is slowly sinking in as it makes ISR significant and highly relevant. Uranium miners adjacent to Cobra are successfully already employing the low cost method. Interest should snowball from here.
