Closure & Remediation
Closure & Remediation
We deliver integrated closure and remediation services to achieve positive environmental, social and economic outcomes, maximising asset value while reducing impact.
We do this by providing specialist expertise and services in the closure and rehabilitation of mines and mine waste landforms, including planning and design, permitting, risk, public safety and environmental hazard liability reduction.
An Industry-Leading, Multi-Disciplinary Team
We understand that when it comes to mine closure and remediation, outcomes are what matter. Our multi-disciplinary team balances environmental, social and economic considerations to ensure the best outcomes, across all areas, and for all parties.
Our team is dedicated to providing integrated solutions. This allows us to maximise asset value and achieve positive outcomes across all areas of each project.
Experienced in Delivering Positive Environmental, Social and Economic Solutions.
With extensive first-hand experience in delivering mine closure and remediation projects from concept to execution, we know what works.
Leveraging industry-leading multi-disciplinary capabilities and delivered through our dedicated closure and remediation team, we provide integrated closure and remediation solutions throughout all phases of mining projects to maximise asset value and achieve positive environmental, social and economic outcomes.
More on What We Do
- When mines and other resource sites have exhausted their supply or are being completed for another reason, we step in to assist you in the creation of the step-by-step plan to undo the damage to the environment and restore social factors while protecting sustainable economic outcomes. We balance all of these factors in an ethical and sustainable manner for the benefit of all.
- Essentially, we help sites to close legally, and ethically, for a greener closure - reducing the environmental impact post-project and restoring the ecological and environmental health of a site.
- We assist from the physical closing and responsible filling of the site to restoring what the site was prior to the project - including replanting trees and plant life, supporting local species to thrive and re-diverting any waterways that were diverted for the project.
- We also help to manage the compliance requirements and technical elements, including testing, consulting and help with legal documentation and reporting when needed. We provide advice on which acts need to be complied with, in what ways, and which paperwork needs to be completed.
