Haranga confirms 96% uranium extraction at Saraya

Haranga Resources (ASX:HAR) says initial leach tests conducted on drillcore from the Saraya uranium deposit in Senegal have achieved 96% uranium extraction. 

The first leach tests were undertaken by SGS Lakefield and supervised by Independent Metallurgical Operations in a program of ore characterisation, which began in March 2024. 

Haranga, which has a market capitalisation of $10.74 million, reports diamond core samples were selected to represent the Mineral Resource Estimate (MRE) grade of 587 parts per million (ppm) triuranium octoxide (U3O8), but realised a head grade 14% higher.

“The acid leach recoveries are pleasingly high, but this was an aggressive test to assess what the limits are. The next work will pare back the aggressive parameters and give a clearer indication of what could be expected in processing of the Saraya mineralised episyenite,” Managing Director Peter Batten says.

“It was interesting to note that the diamond core samples were selected to represent the MRE grade of 587ppm U3O8 and realised a head grade 14% higher. 

The alkaline leach results are also good and gives Haranga two options to consider, if and when we enter Feasibility Studies for the Saraya uranium deposit.”

Haranga notes further work may include a detailed mineralogical investigation to determine uranium mineral and liberation properties, designed to determine if ‘high’ acid-consuming carbonate minerals can be separated from the uranium minerals by most likely flotation, though based on the outcome of the mineralogical assessment, other techniques may also be suitable to trial via testwork. 

Meanwhile, fieldwork is continuing in Senegal following the completion of a reverse circulation drill program in March this year. 

All drilling samples have been collected and are in transit to ALS Laboratories in Canada. 

Haranga Resources is an Africa-focused multi-commodity explorer. The Saraya project in Senegal covers 1,650km2
