Haranga Resources Limited announced that a technical review of historical exploration results has highlighted the strong uranium prospectivity at the Saraya Project in Senegal. As announced on 19 April 2022, Haranga secured access to records of historical exploration at Saraya from the `70s and `80s and from 2008­2010. This included numerous reports and a drilling database of 514 drillholes.

As with most uranium deposits, the equivalent uranium (eU) grades recorded at Saraya are derived from measurements of counts per second (CPS) recorded by down-hole radiometric probes, after the application of correcting factors. The review by independent resource development consultants, RSC, included validating the drillhole database against the original drill logs and establishing a preliminary model of mineralisation to propose efficient verification drilling. RSC concluded that the data is suitable for exploration targeting and support the prospectivity of the project.

RSC noted that if the data is to be considered for future resource classification in accordance with the JORC Code (2012), verification drilling will be required to validate the survey and eU values derived from the probe data. A total of 23 diamond drillholes for 3,200 m has been planned across six areas to validate geological interpretations and eU grades from the historical drillholes. The proposed drilling will use a probe similar to the one used historically to enable comparisons between the datasets.

Diamond drilling will also allow sampling for chemical assays to validate the K-factors used to convert the CPS values into eU grades. The proposed drilling should lead to a more robust understanding of the geological architecture of the Saraya deposit and a validated eU database that could support possible future mineral resource classification in accordance with the JORC Code (2012).
