These two commodities contributed a combined 3.4 percentage points to overall mining output.

Seasonally adjusted mining production rose 3.8% compared with April, after rising 1.5% in April and 7.1% in March.

The three months ending May 30 saw a 3.1% rise in seasonally adjusted mining output compared to the three months prior.
