HOUNDÉ MINE, BURKINA FASO Focused on Sianikoui and Dohoun, and Vindaloo South targets Houndé map INSIGHTS > An exploration programme of $14.0 million is planned for FY-2022, of which $2.1 million was spent in Q1-2022 consisting of approximately 6,500 meters of drilling across 69 drillholes. The exploration programme was focussed on following up on historic drilling results at Sianikoui and Dohoun, and extending the mineralised trend at Vindaloo South. > During Q1-2022 drilling at Sianikoui identified three mineralised trends, with further drilling results pending, mineralisation remains open to the north and the south. Drilling at Dohoun is testing the extension of mineralisation to the southwest, with further drilling planned in Q2-2022. At Vindaloo South diamond drilling was used to delineate the geology and identify the mineralised trend towards the south of the existing mineralisation. > During Q2-2022, drilling will continue at Sianikoui and Dohoun to test the mineralised trends that have been identified. Similarly, exploration programmes are planned at the Grand Espoir, Baraki, Banana, Tioro Sud and Hondjo targets to delineate these prospects. At the Mambo discovery, step-out drilling will focus on extending the mineralised trend to the northeast to fully evaluate the potential size of the Mambo deposit.
