Barton Gold (ASX: BGD) has reported ‘high grade’ assays extending along strike and at depth from the final 29 holes of its Phase 2 drilling program at the Tarcoola Gold Project in South Australia’s Gawler Craton province.
The 3,086m program targeted the southern end of the project’s Perseverance Mine, with results ‘significantly’ extending the mineralised envelope to a further 90m in depth at the north end, 200m at the southern end, and a shallow 350m strike extension at Perseverance West. Key results include:
- 1m @ 2.43 g/t Au from 6m;
- 4m @ 2.88 g/t Au from 27m, including
- 2m @ 4.83 g/t Au from 29m;
- 7m @ 9.72 g/t Au from 42m, including
- 2m @ 23.8 g/t Au from 45m;
- 9m @ 1.70 g/t Au from 76m;
- 1m @ 3.86 g/t Au from 77m (EOH);
- 2m @ 3.35 g/t Au from 95m;
- 5m @ 4.74 g/t Au from 106m;
- 4m @ 11.38 g/t Au from 107m, including
- 1m @ 40.66 g/t Au from 108m;
- 5m @ 48.91 g/t Au from 115m, including
- 4m @ 61.99 g/t Au from 115m;
- 2m @ 7.96 g/t Au from 143m;
- 1m @ 5.92 g/t Au from 229m; and
- 6m @ 5.45 g/t Au from 293m.
Addressing the results, Barton MD Alexander Scanlon said: “Perseverance West is now established as a significant, high-grade extension of the Perseverance Mine, in parallel to the high- grade Perseverance Shear structure. Phase 1 and Phase 2 drilling have yielded some very encouraging grades and intersections to compliment significant historical high-grade intersections near the open pit profile. We have now significantly grown the mineralised profile for the Perseverance Mine, including a ~350m shallow extension.”

Barton reports that historical work at Perseverance had reached depths no lower than 30-75m below surface, and included limited extensional drilling.
Phase 1 drilling, carried out in August 2020 was able to trace mineralisation at the Perseverance West gold zone to over 200m below the pit floor.
Results from Phase 2 drilling have confirmed that Perseverance West is a second high-grade extension to the to the Deliverance Target, measuring approximately 350m in length. This, according to the company, provides ‘significant opportunities’ for mine expansion.
Moving forward, Barton is set to include ground penetrating radar, regional gravity surveys and Phase 2 drilling data into the project’s exploration database, and update the regional structural model as it works towards delivery of a JORC-2012-compliant mineral resource estimate.
Plans for Phase 3 drilling are underway, with recently-discovered shallow targets on ML6455 set for testing, along with a series of regional targets on EL6210.
