The studies were carried out by accredited noise and acoustics companies based in Australia, with both studies concluding that all noise generated by the mine was within regulatory limits.

The Company is working with the EPA to better understand the reasons for the notices issued and will take the necessary steps to ensure that its operations are and remain in compliance with all relevant regulatory requirements.
