Mine & Quarry Closures

Our continued standing in the mining and minerals sector comes from years of collaboration with our valued clients, individual experience and complimentary skills to enable project success. Collectively our in-house professional scientists, engineers and mine closure industry experts bring depth of knowledge and field experience, delivering safe and sustainable innovative mining solutions.

Mine Closure

Managing mine closures requires dynamic strategies and closure plans that can adapt to the evolving life cycle of the project.

We assess future trends and regulatory requirements to provide cost-effective, sustainable closure solutions. Our expert team develops adaptive closure plans that evolve throughout the project lifecycle, ensuring compliance and long-term environmental and social sustainability.

We engage with stakeholders to create holistic solutions and continuously improve plans, maintaining transparency and fostering community support. Our approach ensures that mine closure plans align with regulatory standards and contribute to a lasting legacy of responsible mining.

Quarry Closure

Quarry closure requires dynamic strategies that evolve throughout the quarry’s lifecycle. As closure nears, precise and relevant plans are essential for maintaining community acceptance and social license.

Our sustainable closure plans incorporate technological advancements, regulatory compliance, and stakeholder engagement, ensuring responsible extraction and long-term value while addressing complex closure challenges. With regular progress updates and collaborative stakeholder engagement, our holistic approach works to address community concerns and contribute to responsible extraction by achieving closure objectives and sustainable development.

Cover & Landform

Mine waste landforms, such as tailings storage and waste rock dumps, can pose environmental risks, including heavy metal contamination and water quality degradation.

At SGME, we develop tailored cover and landform designs that ensure safety, stability, and long-term environmental protection. Our engineered solutions integrate innovative technologies, vegetative covers, and sustainable practices to minimise risks and support post-mining land use, fostering ecological function and reducing environmental impacts.
