Post-mine Planning //

Why It Matters

Our Mexican host communities have a vested interest in how we plan for mine closure and reclamation. Every mine has a finite operational life, so managing the effective transition and eventual closure of our mines is an integral part of our business responsibility.

Management Approach

We aim to leave a positive legacy for local communities after our mining activities there have ceased. For us that means considering the entire life cycle of the mines we operate, including the post-mine transition. Proper planning for mine closure is not only important for local communities, it also benefits our business in many ways, including reducing financial risks and liabilities and helping us ensure we set aside adequate future resources.

Environmental Aspects

The major environmental aspects involved in responsibly closing our mines are land reclamation and rehabilitation, the decommissioning of buildings and mine facilities, and ongoing care and maintenance of our legacy properties.

At each site, we have an environmental mine closure plan that outlines how the affected lands will be rehabilitated and the costs associated with doing so. The plans were developed using guidance from the British Columbia Ministry of Energy and Mines and adhere to applicable Mexican environmental laws, including the requirement that tailings ponds be monitored for a certain period of time after reclamation to ensure they are stable and there is minimal risk of a tailings spill.

Social and Economic Aspects

Along with environmental responsibilities, we strive to take a proactive approach to identify and address the social aspects of closing a mine, to ensure that the affected communities are appropriately prepared. While Mexican laws at this time only require companies to prepare environmental closure plans, we are working to integrate social and economic factors in our post-mine planning – so that we consider a broader range of potential community impacts and concerns.

Forward Thinking

Our approach is to reclaim disturbed land wherever possible while mining operations are under way, and well before closure; essentially, as soon as an area is no longer in use. All of our environmental mine closure plans are updated as needed to account for changes in the scope and footprint of our operations and adjust for anticipated costs for remediation or reclamation.

2018 Performance

  • Announced plans to reduce the production rate at El Cubo in 2019 to approximately half its capacity, due to the depleted reserves and current short mine life. This pull back will allow the workers more time to prepare and evaluate opportunities to extend the mine life through exploration.
  • Retained a consulting group to help us create post-mining social plans for our operating mines – see case study.
  • Supported education and skills development to help our workers enhance their future employability and ability to find new career opportunities upon mine closure. For example, since 2015 we have assisted many employees in having their job experience with Endeavour formally recognized through a skills certification program run by the Ministry of Labour.

2019 Priorities

  • Execute the actions identified in the social post-mining sustainability plan, which includes transitioning public services (water, electricity and garbage collection) to the community or the government, supporting workers in the transition to new jobs or other sources of employment, providing education to prevent addictions and illnesses (especially around drugs and alcohol) and promoting education and employability.
