CASTLE LAUNCHES EXTENSIVE AUGER DRILL CAMPAIGN AT KANDIA

About this update from Castle Minerals Ltd

Castle Minerals Limited ('Castle', 'the Company') (ASX:CDT) is pleased to advise that it will shortly undertake a 410-sample power auger drilling campaign at its 100%-owned Kandia Gold Prospect in Ghana's emerging Upper West gold region. This programme is designed to unlock new exploration opportunities by testing for extensions of known gold zones, particularly the Kandia 4000 and 8000 prospects, and multiple new priority targets identified using Castle's proprietary high-resolution aeromagnetic survey data. The campaign will be extended across other Castle licences in the Wa East region (Fig 1) that encompass large tracts of highly prospective Birimian geological terrane, the host to many multi-million-ounce gold deposits in West Africa . These deposits are frequently associated with deeply penetrating geological structures that provide pathways for the migration towards surface of source fluids containing gold. Several such structures traverse Castle's tenure and, using the survey data, the Company has been able to more accurately position where these structures coincide with the Birimian rocks. Using this backdrop Castle has identified and ranked various sites where it might expect to identify near-surface gold anomalism. If anomalism is confirmed by the auger sampling at any of these sites, they will be prioritised for RC drilling. ABOUT GOLD IN NORTHERN GHANA Ghana's 'new frontier' northern region is now considered one of the most prospective areas in West Africa to discover gold deposits. Exploration in the region is relatively immature compared to Ghana's south, where several world-class gold mines have been operating for many decades. This immaturity in the northern region, along with its Birimian geology and structural setting, bodes well for more discoveries to be made and is directly analogous to the similarly prospective geology of Cote d'Ivoire , which is receiving considerable interest from a raft of junior to major explorers. The specific opportunity at Kandia is to delineate a substantial, shallow depth, bulk tonnage of gold mineralisation associated with a 16km southwest-trending prospective sheared contact with an adjacent regional-scale granodiorite intrusion.
