Castle Minerals Limited announced that it has applied for a 133km2 exploration licence encompassing the historical Mt. Barrow graphite occurrence, 15km south east of Castle's Kendenup graphite project in Western Australia's Great Southern region (ELA70/6116). The application is highly complementary to Castle's granted Kendenup and Martagallup exploration licences where the Company will shortly commence a high-resolution ground EM survey to identify possible extensions to known graphitic zones.

The addition of Mt. Barrow also enables Castle to adopt a more regional approach to graphite exploration and discovery. Licence access and Native Title: The Mt.

Barrow exploration licence is well serviced by infrastructure being approximately 5km east of the regional centre of Mt Barker and 45km north of the international Port of Albany. The application area comprises mostly freehold farmland. Once granted, the exploration licence relates only to subsurface rights.

There is a requirement to enter into land access agreements with individual private landowners before DMIRS will grant surface exploration rights. This is a standard requirement and is being progressed through a specialist contractor.
