Aim-listed copper miner Weatherly International’s Tschudi mine, in Namibia, produced 3 236 t in the three months to March 31, 24% below nameplate capacity. This was a result of slower-than-anticipated leach rates for mixed oxide and sulphide ore stacked during the latter part of 2016 and early 2017, further exacerbated by above-average seasonal rains during the quarter, which prevented short-term acceleration of mining and stacking to compensate. However, as rain delays reduced through March the rate of stacking contained copper metal improved notably and these improved rates of stacking copper are expected to be sustained going forward.
