West Cobar Metals (ASX:WC1) expands footprint across prospective Cobar copper corridor

West Cobar Metals has moved to broaden its exploration footprint around its existing Bulla Park copper antimony silver deposit, lodging two new exploration licence applications that expand the company’s tenure across favourable stratigraphy in the region.

The move places the company across a larger section of the geological corridor that hosts multiple mineralised systems in the Cobar Basin.

Highlights

• Two new exploration licence applications lodged in the Cobar district of NSW: ELA7009 (Lilyvale Project) and ELA7010 (Nullagoola Project)

• New applications cover 573km² of prospective ground between the Bulla Park deposit and the CSA and Peak mines

• West Cobar’s exploration tenure, granted and applied for, now totals approximately 1,090km²

• Tenements span approximately 120km strike of favourable Winduck Group stratigraphy

• Multiple gravity anomalies coincide with historical copper, lead and gold geochemical anomalism

• Bulla Park hosts an Inferred Mineral Resource of 20 Mt at 0.58% CuEq (0.30% Cu, 0.10% Sb, 4.7 g/t Ag) at a 0.21% Cu cut off grade

The company’s strategy centres on extending exploration across the same geological setting that hosts its Bulla Park copper antimony silver deposit, which lies approximately 110km west of the Cobar mining centre.

The deposit occurs within the upper part of the Winduck Group sedimentary package and is associated with strong gravity highs generated by dense siderite and barite mineralisation linked to the copper antimony silver system.

The newly applied licences were selected following a review of regional geology together with geochemical and geophysical signatures associated with the Bulla Park deposit.

The applications lie between the Bulla Park deposit and the Peak and CSA mines within the Cobar district. Despite the recognised prospectivity of the area, the company notes that there has been very little previous exploration across the new licence areas.

Strong weathering with possible near surface leaching of geochemical indicators, along with partial coverage by younger Mulga Downs Group sediments, has deterred previous exploration activity.

Historical exploration data provide some context for the target areas. Within the Nullagoola Project area, the Blind Freddie prospect contains a zone of copper, lead and gold soil anomalism extending for more than 3km.

The anomaly occurs along the eastern margin of a gravity high that coincides with a major structure interpreted from aeromagnetic data.

Geological observations from historical drilling at the nearby Elsinore prospect indicate chloritic alteration, quartz veining and rhyodacite dykes within prospective stratigraphy, although no significant mineralisation was reported from that drilling.

These anomalies occur at a similar stratigraphic position to the Bulla Park deposit.

West Cobar Managing Director Matt Szwedzicki highlighted the significance of the licence applications in the context of the company’s broader exploration strategy.

“These new licence applications, over ground highly prospective for copper, antimony, silver and gold, build on what we have learnt at Bulla Park and give our company a major new opportunity to discover and develop new resources in the Cobar District.”

The Bulla Park deposit currently contains an Inferred Mineral Resource of 20 Mt at 0.58% CuEq, comprising 0.30% Cu, 0.10% Sb and 4.7 g/t Ag at a 0.21% Cu cut off grade, with metallurgical testwork to produce a saleable copper silver concentrate and an antimony sulphide product returning recoveries of 94.6% Cu, 82.6% Sb and 84.1% Ag.

Once the new tenements are granted, West Cobar plans to undertake ground gravity surveys, geological mapping and geochemical sampling to define drill targets across the new licence areas.

These exploration programmes are intended to advance targeting across the expanded tenure and assess the potential for additional mineralised systems within the broader Cobar West project area.
