NEWS RELEASE, 7 JUNE 2022

 

 

LOS PELAMBRES - CONCENTRATE PIPELINE INCIDENT

 

On 31 May Los Pelambres detected a leak in the underground pipeline that
transports concentrate from the concentrator plant to the port at Los Vilos.
The pipeline was immediately shut down and the location of the leak
identified. Preliminary assessment shows no indication of any environmental
damage.

Full access to the site is currently being blocked by some members of the
community who are in discussion with the local authorities and representatives
of the Company. Once access is obtained the required repairs will be
completed.

The mining operations and processing plant continue to operate, but with
limitations due to road access restrictions and with the concentrates being
stockpiled at the plant. Once the pipeline has been repaired the stockpiled
material will be transported to the port using the spare capacity in the
pipeline resulting in some rescheduling of sales and shipments.

An assessment of the causes of the leak is underway and any resulting
recommendations will be applied to the concentrate pipeline and the new
replacement pipeline that is currently being designed and permitted, which is
expected to be in operation by 2025.

The full year impact on production will depend on the duration of the shutdown
and if the standstill has created any conditions requiring further actions.
Currently, the impact on Group copper production is expected to be limited to
within the current full year guidance range, which remains unchanged at
640-690,000 tonnes, and subject to any revision following full access to the
pipeline and repairs being completed.

Capital expenditure in bringing the pipeline back to normal operations is not
expected to be material.
