Dateline Resources in Fiji

The company is reviewing its interests in Fiji with a view to identifying a Joint Venture partner that would enter a farm-in-agreement on its Fijian assets.

Udu Mine


The Udu deposit was discovered in 1957 and was developed in the late 1960’s. The mine operated for one year with recorded production totalling 32,435 tonnes of selectively mined material assaying 5.9% copper (“Cu”) and 6.7% zinc (“Zn”). Records indicate treatment on site yielded 5,524 tonnes of concentrates, assaying 18.3% Cu, 1.65g/t gold (“Au”) and 192g/t silver (“Ag”).

The mineralisation consists of a cluster of VMS (Volcanogenic Massive Sulphide) lenses with an overprint of epithermal base metal mineralisation.

Subsequent phases of historical exploration within the Udu Project area largely focused on the immediate Udu Mine area. Historical regional exploration was limited. No drilling had been conducted away from the Mine area until Dateline commenced exploration drilling on regional targets in 2012.

Udu Inferred Resource

A Dateline Scoping Study identified an inferred resource of 4.5 million tonnes of 3.9% zinc and 1.2% copper

Drill-Ready Targets

Nagasauva Target

The Nagasauva target is located 1.8km south of the Udu mine where the 3DIP survey has identified a classic porphyry copper target over an area of 1,000 x 800m at a depth of approximately 600m. The target is associated with a series of stacked, shallowly dipping conductors defined by an airborne VTEM survey in 2010.

Chalcopyrite and malachite have been observed at surface in highly altered felsic volcanics.

Soil sampling has delineated a 700m x 1,100m wide zone of anomalous copper, lead, zinc, gold, silver and barium.  Confirmatory rock chip samples demonstrate the presence of anomalous copper (1,037ppm) silver (2.6g/t) gold (0.02g/t) and zinc (2,922ppm).

No historical drilling has been conducted in the area.

The Company believes there is a possibility of a porphyry style mineralisation system, based upon a combination of base metal and geophysical signatures.

Advanced Exploration Targets

Korobotoni Target

The Korobotoni target is approximately 7.2km south-west of the Udu mine.

• A VTEM geophysical study identified a series of moderate to strong shallowly dipping conductors, estimated at a depth of 50 to 100m below surface.

• The conductors do not break the surface, potentially masking them from classical geochemical exploration.

• Porphyry related volcano-clastics have been identified at the target.

• Geophysical studies have indicated the Korobotoni target is proximal to a zone of magnetite destruction, a potential hydrothermal fluid path.

• Geophysically it has similarities to Nagasauva.

Initial Exploration

The results of an additional soil-sampling program and drilling at Nagasauva will provide the basis to design the next phase of investigation.

Greenfields Targets

Nukusa Target

The Nukasa Target is approximately 8.5km south-west of the Udu Mine.

• The target has identified sub-cropping, weathered sulphide veins with grades of up to 5.1ppm Ag, 1,310ppm Cu and 666ppm Zn.

• Regional soil sampling traverses the area have defined a zone of moderate copper anomalism across an area of approximately 500m x 700m strike length, which has yet to be closed off.

Infill geochemical sampling and mapping is required to define a drill target on the prospect.

Vatu/Wainika Targets

The Vatu and Wainika targets are located near the southern coastline to the east of the Korobotoni target.

• The targets are centred on two discrete highly conductive targets defined by the VTEM airborne survey.

Nakula SPL 1494

The Nakula SPL 1494 is located approximately 13km south-west of the Udu Mine and was granted to Dateline in January 2012. It covers a historical stream sediment-sampling anomaly draining an area described as a potential porphyry system by previous leaseholders.

• Historical stream sediment sampling up to 61ppm Cu, 0.3ppb Au and 152ppm Zn.

• Confirmation sampling by Dateline returned stream sediment samples up to 1ppb Au, 81ppm Cu and 240ppm Zn.

• Samples of mineralized porphyry float in the area returned values of up to 0.9ppm Ag and 1,190ppm Zn.
