The series of International Conferences on Mine Closure is a fixture on the calendars of many mining professionals, providing topical and high-quality papers and presentations on a range of topics of immediate interest and relevance.

The conference will cover themes ranging from planning, relinquishment and legacy management, stakeholders and community, engineering and landform design, water management, decommissioning and waste management, ecosystem reconstruction, financing and cost estimation, site remediation and impact management, and project management and execution. 

A key feature of the conference series is the diversity of disciplines and expertise that will come together to focus on the pressing issues facing the mine closure community globally.

About Our Workshop

Join our mine closure specialists from around the globe for a one-day workshop on:

Creating Value from Closure
Monday 2 October, 9.00 am – 3.00 pm
Cost: USD$350

The workshop will look at mine closure being viewed as an opportunity to reduce overall liability for mining companies while finding value in unexpected places.

ERM has developed tools to help mining companies define, refine, assess, and choose preferred closure options that result in reduced liabilities, alternative closure visions, and finding value where it wasn’t seen previously.

Highlights include:

-Discover new ways to approach mine closure as an opportunity to create value.
-Uncover ways to integrate value creation into your closure concept.
-Understand how to assess closure concepts that incorporate value creation.
