Yandan

Straits Gold Pty Ltd (a wholly-owned subsidiary of Aeris Resources Limited) is the 100 per cent holder of the tenements comprising the Yandan Project (“Yandan”). Yandan is located approximately 40 kilometres to the west of Mount Coolon and 155 kilometres south east of Charters Towers in North Queensland. Yandan is located on the eastern margin of the Drummond Basin, proximal to the contact of the Drummond Basin within the Anakie Inlier. The Drummond Basin is highly prospective for epithermal gold-rich mineral systems, most notable for the Pajingo (~5Moz), Ravenswood (~4Moz) and Mt Leyshon (~3.5Moz) mines.

The Yandan gold mine was operated by Ross Mining between 1985 and 1990 and produced more than 350,000 ounces of gold by heap leach and from a CIL (carbon-in-leach) plant. An initial Mineral Resource Estimate (JORC 2004 compliant) has been determined for the East Hill mineralised system:

  • 4Mt at 2.4g/t for 308,000 ounces of gold Inferred Resource with no lower cut-off.1

Regional studies have defined other mineralised centres with significant potential to delineate economic gold systems, including the Illamahta prospect which represents a shallow low-grade mineralised system approximately 14 kilometres south-west of the Yandan deposit.

During the year an RC drill program was completed at the Illamahta prospect – a shallow oxide gold mineralised system first discovered by Western Mining Company (WMC) in the early 1990’s. Samples collected from the program will be used for metallurgical test work evaluating the leachability of gold from the host rock.

The mining lease has significant water dams and rights to harvest water from the adjacent Sutor River.

The Company is committed to delivering value for shareholders from this asset and is considering future options to achieve this.
