Highlights
- Initial leach tests on drill core from the Saraya deposit confirmed >96% uranium extraction under atmospheric leach conditions using sulphuric acid.
- The diamond core samples, intended to represent a mineral resource grade of 587 ppm U3O8, yielded a head grade 14% higher.
- In 2Q, the company expects further metallurgical testwork results, RC drilling assays, infill/regional sampling, auger results and potential resource category upgrade.
Haranga Resources Limited (ASX: HAR; FRA: 65E0) has announced promising outcomes from the first leach tests undertaken on drill core samples from the Saraya uranium deposit. The testwork was carried out as part of an ore characterisation program that began in March 2024.
The leach results confirmed >96% uranium extraction under atmospheric leach conditions utilising sulphuric acid. Meanwhile, employing an alkaline atmospheric leach yielded 84% uranium extraction.
Aggressive addition of high reagents and high-temperature conditions were employed for both leaching processes to verify the amenability of uranium extraction.
It is noteworthy that the diamond core samples selected to represent a mineral resource grade of 587 ppm U3O8 yielded a head grade 14% higher.
HAR shares traded at AU$0.120 apiece at the time of writing on 4 April 2024.
