We are humbled by this extraordinary vote of confidence and the universally positive feedback received.

“Together with our recent $15m Placement, we are well capitalised to continue methodically building and unlocking long term value for Barton’s shareholders. The next year will be exciting as we advance our Central Gawler Mill toward ‘Stage 1′ operations, and our ‘Stage 2′ Tunkillia project toward a Mining Lease application.”
