Drilling Expands Breccia Pipe Interval at Red Setter Gold Project in Western Australia

152m of Breccia within overall 257m zone of Quartz-carbonate veining and sulphides

Wishbone Gold Plc is pleased to announce that drilling at the Company's Red Setter Gold Dome Project, located 15km South-West of Greatland Gold Plc's (AIM and ASX: GGP) Telfer gold mine in Western Australia (Figure 1), has drilled the breccia identified in hole number 25RSDD001 down to a depth of 777m (Figures 2-3), an interval of 152m, with Quartz-carbonate veining and sulphides of chalcopyrite and pyrite on either side from 520m-777m a total zone of 257m.

Quartz-carbonate veining and sulphides of chalcopyrite and pyrite have now been observed from 520m, with increasing intensity to ~570m down hole. From 570m to 722m an interval of 152m a breccia pipe was intersected, with quartz-carbonate veining and sulphides of chalcopyrite and pyrite observed to end of hole at 777m (Figures 4-10).

This hole will be potentially drilled deeper later on in this program, when additional drill pipe is mobilised to site by the drilling contractor.

The drill core is currently being transported from site to Perth to be cut and assayed.

Ed Mead, Wishbone Gold WA director, commented; "We decided to call it a day for now at 777m depth in this first hole at Red Setter as we await the delivery of more drill rods to site to drill deeper safely. Depending on what we see in the second hole, we will be in a position to extend the depth of this first hole later on in the program. The drill rig will now be setting up on a step-out hole to test the breccia pipe more towards the centre of the system. The plan is to drill the top of the second hole with a rotary mud bit to a depth of approximately 150m before setting casing and drilling on with PQ diamond core followed by narrower NQ core to final depth. The drilling contractor has been asked to mobilise enough drill rods to reach depths of over 1,000m for this program and the Company is investigating the possibility of running the drill program on a double shift basis."
