Haranga Resources’ final RC holes continue Saraya mineralisation with more thick uranium intersections
Hits of up to 36m at 913ppm eU3O8 extend previously reported positive results
Pending laboratory assays to feed into upcoming resource update
Auger drilling to continue at Diobi, Mandankoly and Sanela targets
Special Report: Haranga Resources will almost certainly upgrade resources at its Saraya uranium project in Senegal after the final 19 holes in its reverse circulation drill program returned more thick uranium intersections.
The RC program was designed to produce confirmation data for the resource estimate upgrade works for the project, which currently has a resource of 12.4Mt at 587ppm eU3O8 for 16.1Mlb of contained U3O8.
The first eight holes returned significant widths and concentrations that proved to Haranga Resources (ASX:HAR) uranium mineralisation at Saraya is consistent with the model and the resource estimate published in October 2023.
Metallurgical testing has also proved that ore from the project is amendable to extraction using sulphuric acid, which achieved more than 96% U3O8 recovery.
The company is also using termite mound sampling as a quick and cost-effective method of defining uranium targets within the Saraya project area – a process that has already outlined multiple anomalies for further testing using auger drilling.

More uranium assays
Samples from the final 19 RC holes at the project have been processed using pXRF to determine anomalism and sent to ALS Laboratories in Canada for assaying.
While not intended to be used as a replacement for laboratory testing, the pXRF has indicated that these holes intersected significant near-surface mineralisation over wide zones with notable results such as:
36m at 913ppm eU3O8 from 39m including 14m at 1700ppm eU3O8 from 45m (24-SAR-RC-010)
12m at 725ppm eU3O8 from 9m including 9m at 896ppm eU3O8 from 10m and 9m at 844ppm eU3O8 from 27m including 6m at 1159ppm eU3O8 from 29m (24-SAR-RC-011); and,
19m at 554ppm eU3O8 from 15m including 7m at 801ppm eU3O8 from 26m (24-SAR-RC-012)
Meanwhile, five of the six holes drilled at the Sanela anomaly returned significant anomalism topping up at 8m grading 351ppm eU3O8 from 35m including 3m at 583ppm eU3O8 from 40m.
“The latest pXRF results from the extensional RC drilling are extending the positive results previously reported for Saraya,” managing director Peter Batten said.
“All samples have now been delivered to ALS in Canada and we look forward to the assay results, that will allow for a revision of the mineral resource estimation for the Saraya uranium deposit.
“The RC drill results from the previously defined Sanela anomaly, are the first mineralisation intersected in drilling by Haranga and will require follow up at a later date.”
Ongoing work
Auger drilling will continue at the Diobi, Mandankoly and Sanela targets to further test the anomalism at these sites.
Priority is given to Sanela, but the results at all sites require further exploration to determine the source and tenor of uranium anomalism detected from current exploration.
Regional termite mound sampling over the entire permit is expected to be completed in the current quarter.
