Zimplats Output Hit by Smelter Maintenance Despite Stronger Mining Volumes

An update from Zimplats Holdings Limited ( (AU:ZIM) ) is now available.

Zimplats reported a mixed operational performance for the quarter ended 31 March 2026, with mined ore volumes down 1% from the prior quarter but up 17% year-on-year on stronger open-pit output and better underground fleet availability. Milled volumes fell 6% quarter-on-quarter due to mill relines but rose 15% versus a year earlier, while 6E head grade slipped modestly on higher open-pit throughput and geological dilution.

Production of 6E metal in concentrate declined 6% from the previous quarter but was 18% higher year-on-year, reflecting improved ore generation and stable concentrator recoveries. However, final 6E metal output slumped 56% quarter-on-quarter and 46% year-on-year because of scheduled smelter maintenance, driving a sharp rise in unit cash costs, though matte tapping has resumed and accumulated concentrate stocks are expected to be processed by the end of the financial year.

The company recorded one lost-time injury during the quarter, with investigations completed and corrective actions implemented as management reiterated its goal of a zero-harm workplace. The temporary production setback from smelter maintenance suggests near-term earnings pressure, but the build-up of concentrate stocks and stronger year-on-year mining and milling performance indicate potential recovery once full smelting capacity is restored.
