Barton Gold Holdings (OTCQB:BGDFF) has announced an updated Mineral Resources estimate for its Tunkillia Gold Project in South Australia. The update reveals a significant increase to 1.6 million ounces of gold and 3.1 million ounces of silver in JORC Resources.

The resource expansion follows approximately 5,000 meters of reverse circulation (RC) drilling that enabled extensions of previous MRE block models. The company expects improved economics in the forthcoming Optimised Scoping Study, citing material efficiencies and power savings in their comminution modeling.
