Castle’s Polelle and Wanganui projects and other key operators in the Meekatharra region

The Polelle project (E51/1843, 144.5km²), 25km south of Meekatharra and 7km southeast of the operating Bluebird Mine, hosts a mainly obscured and minimally explored greenstone belt comprising a combination of prospective lithological units and major structural features. This includes the Albury Heath shear which hosts the Albury Heath deposit (Inferred Resource of 528,000t at 2.09g/t Au for 35,479oz Au) immediately adjacent to the east boundary of the licence. Aeromagnetics have indicated that the southwest trending Albury Heath shear is traceable onto the Polelle project area for some 7.5km.

Reinforcing the excellent location of Polelle, is that it is 12km west of the Gabanintha Mine, 11km east of the Nannine group of gold mines and is easily accessed via sealed and good quality unsealed highways.

Whilst historical exploration has generated sporadic shallow RAB drill hole, rock chip and geochemical gold anomalies, the sampling techniques employed are considered unreliable given that 70% of the project area is covered by a veneer of transported cover.

The opportunity therefore is for Castle to use a modern understanding of regional and local tectonics, structure and the regolith along with appropriately designed sampling techniques to more effectively test the underlying prospective Archaean greenstone lithologies for gold.

Following the completion of a specialist geochemical data review of historical and Castle stream sediment, soil and rock chip sampling campaigns, several priority targets for gold and base metals have been defined. The Company is now making plans to drill test the highest ranked of targets.
