Barton Gold Holdings Limited - High Resolution Gravity Survey Targets Challenger Repeats

About this update from Barton Gold Holdings Limited

ADELAIDE, AUSTRALIA - Barton Gold Holdings Limited (ASX: BGD) (OTCQB: BGDFF) (FRA: BGD3) (Barton or Company) is pleased to confirm the start of a high resolution airborne gravity survey surrounding its South Australian Challenger Gold Project (Challenger). The program is part of Barton's research and development (R&D) initiatives trialling various technologies in historically under-explored terrain to define new geological models. Commenting on the Challenger gravity survey, Barton Managing Director Alexander Scanlon said: 'With a DFS underway for the phased restart of operations at Challenger, leveraging our Central Gawler Mill , we are diligently pursuing our regional enhancement strategy. This includes not only our Tarcoola and Wudinna blending feed projects, but also the potential for near-mine repeats of Challenger's high-grade quartz vein lodes. 'Challenger was developed during a period of record low gold prices, and as such historical investment favoured rapid development over local exploration. With existing infrastructure, new discoveries could be highly valuable.' Program details Barton has engaged Xcalibur Smart Mapping (Xcalibur) to undertake a FALCON airborne gravity survey over the northern portion of Exploration License (EL) 6502. The program will include approximately 3,200 line kilometres of data collected, with survey lines flown at 200m spacing and approximately 80m altitude. The Challenger Gold Mine is located on Mining Leases (ML) 6103 and 6457, both situated in the southwest corner of the northern portion of EL 6502. Challenger produced approximately 1.2 million ounces of gold during 2002 - 2018, and Barton maintains 100% of the gold rights over the northern portion of EL 6502. Challenger gold mineralisation occurs in a cluster of highly continuous, deformed quartz vein lodes plunging to 1.3km depth including Challenger West (CW), Challenger South-Southwest (CSSW), Aminus, M1, M2, M3 and South East Zone (SEZ). Existing ground gravity data around Challenger is very coarse, and it is theorised that high resolution data may provide a complimentary dataset to existing magnetics, aid in the interpretations of the regional structural setting, and assist with the identification of analogous host geological settings and associated structural targets that may lack a surface geochemical expression.
