- Rambler Metals and Mining said it produced more gold and copper concentrate in the second quarter, as it reaped the benefits of a mining process improvement programme initiated last year.

The company, however, downgraded its gold production and grade guidance for the full year.

The company said it produced 5,425 dry tonnes in the six months through June, up from 3,643 on-year.

Saleable metal production of copper rose to 1,417, up from 978, while saleable metal production of gold rose to 1,321, up from 1,199.
