Barton Gold Holdings Limited confirmed an updated Mineral Resources Estimate for its South Australian Tarcoola Gold Project (Tarcoola). Approximately 1,688m of recent Barton drilling has delivered an updated JORC (2012) Mineral Resources Estimate (MRE) of 19.9koz Au within 60 - 80m of the Perseverance Mine open pit floor. The total Tarcoola MRE is now 29.5koz Au (0.54Mt @ 1.70 g/t Au), with ~45% classified as ?Indicated' category, including 9.6koz Au contained in lower-grade existing stockpiles next to the Perseverance Mine.

The historical Tarcoola Goldfield produced ~77koz Au at an average grade of ~37.5 g/t during 1893 - 1955 from shallow workings on Barton's Mining Lease 6455, and a small open pit mine (Perseverance) produced ore grading 2 - 4 g/t Au to Barton's Central Gawler Mill during 2016 - 2018. Notwithstanding this ~130 year history, relatively little has been historically invested to evaluate the goldfield's architecture or locating prospective ?repeats' of shallow, high-grade mineralisation in the surrounding area. Barton's regional development strategy is to establish large-scale, bulk open pit mineralisation combined with nearby higher-grade blending feed to realise the benefits of economies of scale, and to potentially support an early ?Stage 1' operation leveraging the existing Central Gawler Mill to process these materials.

The company has rapidly grown the neighbouring Tunkillia Gold Project (Tunkillia) to a JORC MRE of 1.5Moz Au (51.3Mt @ 0.91 g/t Au) over the past two years. A preliminary Scoping Study is now underway to test a prospective 5Mtpa processing model, and to identify key cost drivers for subsequent optimisation.
