Mamba Exploration Limited announced the discovery of massive and semi massive sulphide mineralisation in the first diamond drill hole (21BHRC001) at the high priority target, southern prospect at Black Hills. Visual logging has been completed on the first hole and has identified massive and semi massive sulphide mineralisation within a broader zone of disseminated sulphide mineralisation at the depth of the modelled EM conductor at the BH-1 South target. The sulphides are dominated by fine grained pyrrhotite (80%) and pyrite (20%).

The diamond core for the sulphide mineralisation zone has been processed and cut, with samples already submitted to ALS Ltd. in Perth for analysis, and results are expected to take around 3 to 4 weeks to be received. Diamond drilling is continuing with the second hole currently at a depth of approximately 100m. Given the correlation between the massive sulphide mineralisation and the modelled position of the fixed loop surface EM conductor, it is clear the sulphide zone is the conductor.

This is encouraging as it shows that the exploration techniques being used have identified the zone of interest. To better understand the orientation of the sulphide mineralisation and EM conductor, a downhole EM survey is planned for later this week. This survey is expected to better resolve the orientation and size of the conductor and identify if there are other off hole conductors that are yet to be tested.
