Drilling by Antares Minerals (ANM-V) at the Haquira porphyry-copper project in southern Peru has intersected high-grade leachable copper mineralization on a western extension of the known deposit.
A 22.2-metre interval in drill hole AHAD-031, drilled about 270 metres southwest of previous mineralized intersections, averaged 2.07% copper. The result shows that the copper mineralization at Haquira does extend west of the known deposit.
Four other drill holes tested geological and geophysical targets well beyond the Haquira resource.
A new resource estimate, done for Antares by Denver consulting firm Chlumsky, Armbrust and Meyer, put the inferred oxide and secondary-sulphide resource at 156 million tonnes grading 0.49% copper. Another inferred resource of 97 million tonnes grading 0.42% copper consists of primary sulphide material.
Leachability tests on the samples from Hole 031 showed 93.5% of the copper was extracted by either sulphuric acid or sodium cyanide.
Another 14,000 to 18,000 metres of drilling is planned, starting in June. The drilling will concentrate on in-fill holes in a planned starter pit in the secondary-copper resource and on extensions of the inferred resource.
