CASTILE RESOURCES DRILLING PROGRAM UPDATE

Castile Resources Limited ( ASX:CST ) ( Castile or the Company ) is pleased to provide the following update on the planned drilling program for the remainder of the drilling season.

It is anticipated that the resource definition drilling at Rover 1 will be complete within three weeks which will allow for drilling to begin on the Company’s nearby prospects which contain significant resources that demand assessment.

In the backdrop of the infill and extensional drilling program at Rover 1 the Castile team has been trialing more modern and more powerful down-hole electrophysical probes at the Explorer 108, Explorer 142 and the Rover 3 Prospects.

EXPLORER 142

At the completion of drilling at Rover 1 the rig will mobilise to Explorer 142 to test a newly defined deeper conductor withing 150m of previous drill intercepts. This target is sitting below the already defined copper mineralisation.

EXPLORER 108

At the completion of the work at Explorer 142 the rig will be mobilised to Explorer 108 to further test for the continuity of the lead and zinc mineralization defined in the carbonate rich sediments previously associated with the lead and zinc mineralisation defined at the prospect.
