Sydney, Aug. 2, 2022 /Medianet/ —
Highlights:
- Assay results from drilling at Flying Horse, a copper sulphide resource at Mt Kelly includes 14m @ 2.23% Cu, 11m @ 2.30% Cu and 19m @ 1.69% Cu
- Continued evaluation of potential suitability of Mt Kelly copper sulphide ore for sulphide heap leach SX-EW technology
- Austral to accelerate determining the potential for economic extraction of copper sulphide resource at Mt Kelly
Copper producer Austral Resources Australia Ltd (ASX:AR1) (“Austral” or the “Company”) is pleased to announce the drilling results from the Flying Horse diamond drilling program.
Flying Horse (FH) is located on an existing Mining Lease (ML5447) and contains a JORC Mineral Resource Estimate of 14.2MT at 0.77% Cu – see Table 1 below (1) . The quoted resource was calculated in 2013 by the previous mine owner.
As previously announced , Austral Resources completed a 3-hole diamond drilling program for a total of 712m at Flying Horse to provide fresh ore samples for a metallurgical test work programme (Figure 1 & Figure 2). This program evaluates the suitability of Mt Kelly sulphide (chalcopyrite) mineralisation for an emerging sulphide heap leach SX-EW technology. If the evaluation is positive, there is exciting potential for Austral to have an additional processing solution relative to conventional flotation for its sulphide resource base of 26.5Mt@ 0.8% Cu.

About us:
Austral Resources Australia Ltd is an ASX listed copper cathode producer operating in the Mt Isa region, Queensland, Australia. Its Mt Kelly copper oxide heap leach and solvent extraction electrowinning (SXEW) plant has a nameplate capacity of 30,000tpa of copper cathode. Austral has developed its Anthill oxide copper mine which has an Ore Reserve of 5.06Mt at 0.94% Cu. The Company expects to produce 40,000t of copper cathode over a four-year period from mid-2022.
Austral also owns a significant copper inventory with a JORC compliant Mineral Resource Estimate of 60Mt@ 0.7% Cu (420,000t of contained copper) and 2,100km2 of highly prospective exploration tenure in the heart of the Mt Isa district, a world class copper and base metals province. The Company is implementing an intensive exploration and development programme designed to extend the life of mine, increase its resource base and then review options to commercialise its copper resources.
