SnapshotThe Jundee operations are part of Yandal Production Centre. The Jundee Operations include the Jundee and satellite mines of the Julius and Ramone, and the Jundee processing plant.

In 2023, ore was mined from the Jundee and Ramone underground mines. Mining at the Julius open pit ceased as planned at the end of 2022.

Northern Star has entered into a long-term power supply agreement at Jundee for a renewable energy project which incorporates a solar farm, battery energy storage facility and four wind turbines.

Summary:

Jundee
Jundee is an Archean gold mineralised deposit that is part of the Northern Yandal Greenstone belt. Gold mineralisation is controlled by a brittle fracture-system, is commonly fracture-centred, and is predominantly hosted in dolerite and basalt. Mineralisation can be disseminated or vein style host.

Jundee Open Pit
Mineralized zones are variable with true width ranging from 0.5m to 20m. They are extensive along strike and down dip, up to 450m and 350m, respectively. Depth from surface is 350m approximately.

Jundee Underground
Mineralised zones are narrow, with true width ranging from 0.3 to 1m, but can be up to 5m. They are extensive along strike and down dip, up to 1000m and 500m, respectively, but are often highly discontinuous, and generally have a tabular geometry.

Depth = surface to ~1710mRl (~845m below surface).

Jundee (Ramone)
Ramone is Archean gold mineralised deposit that is part of the Northern Yandal Greenstone belt. Gold mineralisation is hosted by a granite and controlled by a brittle stockwork fracture-system within a north-easterly trending shear zone. The mineralisation formed by a stockwork of veins with smoky quartz, sulphides, minor carbonate, chlorite and sericite hosted by a monzonitic granite. The mineralisation is intruded by an east-west striking (about 096 degrees) vertical dolerite dyke that cross cuts the mineralisation and is part of a suite of magnetic dolerite dykes that intrudes the Yandal belt in an east-west direction.

Mineralised zones are variable with true width ranging from 0.5m to 20m. They are extensive along strike and down dip, up to 600m and 400m, respectively. Depth from surface is 400m approximately.

Jundee (Julius)
Julius is an Archean gold mineralised deposit that is part of the Northern Yandal Greenstone belt. Gold mineralisation is controlled by a shear system and is predominantly hosted in ultramafic and granite. Mineralisation can be lateritic, or supergene or vein style hosted in nature.

Mineralized zones are variable with true width ranging from 0.5m to 20m. They are extensive along strike and down dip, and form supergene and laterite horizons, respectively.

Mineralisation occurs form near surface and is open at depth >200m approximately.
