Snapshot	Mining ceased in the Way Linggo pit on December 19, 2019 as planned. Rehabilitation on the area has begun. Although it is recognised that mining operations may restart at a future date, the Company commenced closure and reclamation of areas of the Way Linggo site that are not deemed of value to future mining. During the 2023 financial year, Kingsrose Mining Limited completed the sale of its interest in the Way Linggo gold project to Capwill Global Limited by announcement on 16 December 2022. Capwill Global Limited is a private limited liability company registered in Hong Kong. Despite the change in ownership, as of December 5, 2024, there have been no official announcements regarding the resumption of mining operations at the site.

Deposit type

• Epithermal
• Vein / narrow vein

Summary:

The Way Linggo deposit is an epithermal gold / silver deposit. Epithermal gold-silver-quartz vein mineralisation has been identified at Way Linggo. Economic mineralisation is predominantly restricted to the major vein structures, with the majority of gold and silver contained in main-stage banded quartz veins and quartz vein breccia.

Way Linggo located on western margin of older Miocene volcanic rocks (Tomh) surrounded by younger tuffaceous rocks (Qhv). A prominent pull-apart basin occurs to the west of Way Linggo.

Intrusions are localized by the intersection of NW-, NE- and N-trending lineaments and pre-date the emplacement of the epithermal veins in both areas.

Clay-pyrite (argillic) alteration, pervasive silicification and quartz veins coincide with NW- and N-trends (argillic alteration, silicification and quartz veins) and NE-trends(silicification) locally. The vein systems and related hydrothermal alteration are localized in zones of lineament intersection and nearby dacite intrusions.

The vein systems and related hydrothermal alteration are localized in zones of lineament intersection and nearby dacite intrusions. Both prospects are inferred to lie in the same 3 km by 1.5 km hydrothermal cell that is defined by NW- and N-trending fault- and fracture-zones.

The surface quartz veins south of the Semung river predominantly strike NW and dip moderately to steeply towardsthe NE. In contrast, the surface quartz veins north of the river (89 measurements) indicate NW-, NNW- and N strikes and dip steeply towardsthe NE or E.

The surface quartz veins measured at Semung Kecil (82 measurements) show a slightly more northerly strike than the majority of the quartz veins at way Linggo and commonly dip steeply towardsthe southwest.

Pervasive silica-pyrite altered sedimentary rock in the South vein area of Way Linggo. This siltstone is inferred to have been deposited in a NE-trending fault-controlled basin (sag pond) during a volcanic hiatus; Pervasive silicification and minor quartz veins trend N30 – 40oE and dip steeply NW (outcrop and sub-crop samples in Way Sapta contain up to 2.2 g/t Au, 18 g/t Ag, 467 ppm As).

Quarry vein showing convoluted colloform banding in chalcedony and quartz: Interpreted to indicate the upper levels of a productive epithermalsystem (rock channel samples indicate up to 2.5 g/t Au and 89 g/t Ag).

Vein B underground mine: High-grade Au-Ag localized within fine-grained sulphidic (dark grey) bandsin colloform banded quartz vein 26.4 g/t Au and 339 g/t Ag.
