Tarcoola Mine

Tarcoola Open Pit Gold Mine, ROM Pad & Waste Dump


Tarcoola is an open pit South Australian gold mine wholly-owned by Barton Gold. The project is situated on an existing Mining Lease, within a ~ 1,200 square kilometre tenement package. The mine is located adjacent to the town of Tarcoola approximately 120km SE of Barton's processing plant, approximately 70km NW of Barton's wholly-owned Tunkillia Project, and approximately 600km NW of Adelaide, South Australia.

Tarcoola is an advanced project and is a near-term operations restart project for the Company targeting current inventory in mine plan and significant mineralised extensions along strike and to depth from the current open pit (Perseverance Pit). The Company believes that the Perseverance Pit, its extensions, and nearby shallow, high-grade mineralisation offer significant potential as a long-term, high-grade source of ore.

A Definitive Feasibility Study (DFS) was completed September 2016, with operations commencing December 2016 and first ore haulage during January 2017. Prior to being placed on Care & Maintenance during 2018 the mine consistently produced ore grading in excess of 4 g/t Au, and did not complete its initial mine plan.


During 2018 an estimate of remaining mineralisation was prepared by a Competent Person. While the physical parameters were estimated in accordance with JORC guidelines, the nature in which the numbers were reported were not in accordance with a JORC compliant statement, and are therefor considered non-JORC. 

These include:

  • Estimated in-situ resources of 843,700 tonnes grading 1.7 g/t Au, for 45,400 ounces Au; and

  • Estimated low-grade stockpile of 258,000 tonnes grading 1.29 g/t Au, for 10,700 ounces Au

The broader Tarcoola Mining Lease hosts numerous mineralised structures and some 600+ historical high grade workings including 'Tarcoola Blocks' which produced some 57,000 ounces at a grade of ~43 g/t Au.

Immediate Opportunities

Tarcoola offers multiple near-term avenues for value-addition in the immediate vicinity of the Perseverance Pit. Prior mining operations were terminated abruptly and prematurely, leaving high grade mine inventory within the pit estimated (non-JORC) at approximately 60,000 tonnes grading 2.8 g/t Au. Numerous previous drilling intercepts prior to, and during operations indicate significant potential to further extend the Perseverance Pit with three live mineralised structured converging toward the base of the pit and extending primarily to the SSW.

These prior intercepts include several high-grade results indicating the potential to lengthen, deepen and widen the Perseverance Pit, as well as potential for future underground operations in the 'Deliverance Target'.

These include:​

Perseverance Shear​

  • 1m @ 125 g/t Au

  • 5m @ 20.6 g/t Au

  • 2m @ 33.8 g/t Au

  • 1m @ 12.2 g/t Au

  • 2m @ 14.7 g/t Au

  • 1m @ 14.3 g/t Au

Granite Vein (Under Pit)

  • 4m @ 14.8 g/t Au

  • 2m @ 13.7 g/t Au

  • 5m @ 4.3 g/t Au

Granite Vein (SSW of Pit)

  • 6m @ 43.6 g/t Au

  • 1m @ 34.7 g/t Au

  • 4m @ 3.5 g/t Au

Long Section - Perseverance Pit & Deliverance Target

Additionally, prior drilling results identified broad, high-grade mineralisation immediately adjacent to the Perseverance Pit and on the Tarcoola ML. These were not followed up due to budget restrictions.

These include the following results, all shallower than 75m depth and within ~1km of the Perseverance Pit:

  • 22m @ 6.75 g/t Au

  • 3m @ 5.03 g/t Au

  • 2m @ 6.42 g/t Au

  • 1m @ 21.41 g/t Au

  • 2m @ 39.9 g/t Au

Tarcoola Shallow High-Grade Near-Mine Intercepts


Mining of the Perseverance Pit and other mineralised targets on the Tarcoola ML will initially involve conventional open pit mining methods with ore haulage ~160km to Barton's wholly-owned processing plant.

Barton Gold is targeting a restart of the Tarcoola Mine during 2021.
