Rotary percussion drilling (61 vertical holes totalling 2895 m), which was designed to try to delineate possible remnant oxidised copper ore reserves at the Paratoo copper mine, 20 km south-west of Yunta, has defined an Inferred mineral resource of 100,000 t grading on average <1% Cu, that is present in three mineralised zones occurring over a 300 m strike distance near the old open pits. A best drilling intercept of 23 m @ 1.22% Cu extending down from the surface was made in hole PT13, within lode rocks that possibly lie at the same stratigraphic level as those identified at the historic Burra mine. Testing of the ore zones for carried gold values gave minimal results. Adelaide & Wallaroo were hoping to find enough copper ore at shallow depths to supply extra feedstock to their contemporary Burra minesite processing operation, but the grades and widths of the Paratoo occurrence are too small to warrant extraction.
