Production Start...
Gold and silver production at Talang Santo was active between 2014 and 2020 from both open-pit and underground mines. Mining operations have been placed on care and maintenance while further exploration is conducted.

The Company entered into a process deed for the potential acquisition of the Way Linggo project by a third party as announced to the ASX on 1 July 2022.

Deposit Type

  • Epithermal


Summary:

The Talang Santo deposit is a low-sulphidation epithermal gold-silver system, with the majority of Mineral Resources hosted in a vein and breccia zone that has been traced over 1.4 kilometres strike and up to 450 metres depth.

The Talang Santo deposit is centred on an extensive epithermal quartz vein system, which has been interpreted over a strike of approximately 1.4 kilometres, with the best mineralisation being exhibited over 550 metres of this strike.

Conceptually, the main interpreted domain for estimation is an individual continuous structural zone, modelled over the entire strike length. Within this zone, there are multiple mineralisation styles including banded epithermal veining, breccia, stockwork, clay alteration and fault gouge. For practical purposes, these related mineralised styles within the same structural corridor have been combined for estimation as a single package.

Subordinate mineralised zones, ‘splays’ to the main structure, have also been modelled. These are a similar mineralisation style to the main zone but generally trend northwest intersecting the main zone at an angle of approximately 30 degrees.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Production of gold and silver commenced from the Talang Santo underground mine in July 2014 (sub-level stoping and room-and-pillar mining methods). Underground mining occurred up until 2018.

In November 2018, Talang Santo open pit has started. The Talang Santo open pit is similar to the Way Linggo open pit in that the mine will be located on the previously mined underground ore body. The open pit will extract upper levels of the remnant ore pillars and areas of the mine that were left behind, due to the mining method employed in the underground mine. It is estimated that there is 50% of the orebody remaining in the area which will be the subject of the open pit.

Planned mining in the Talang Santo open pit was completed in April 2020.
