Our Remediation Process

Oceano Verde’s goal is to provide residual benefits to the indigenous inhabitants of the regions in which we operate. We will be providing sustainable jobs to these people, with work that will continue even after active mining operations are completed. We will restore the land and water to its natural state – following The World Health Organization (WHO) standards for water and creating arable and pasture land. Below, we will describe the activities that will allow us to achieve this goal.


Restoring Environmental Function at Mine Sites through Remediation

As mining is a temporary activity, a mine closure is a natural step in the mining lifecycle. Mining sites have finite operating lives which are determined by the size and quality of the mineral being mined. A mine closure will occur once the mineral resources at the working mine are exhausted. Mine remediation is a term used to describe the process of remediating land that was once mined. Restoring mined land to a more natural condition is a top priority of our company, local stakeholders, and the global public.

We understand that planning for the mine remediation process begins well before the mine is permitted. Companies are required to submit and execute plans for the closing of mines and grant environmental guarantees to secure compliance with Closure Plans.

New mining development and production activities in Peru are required to file and obtain approval for an Environmental Impact Study (EIS). This study looks at technical, environmental and social matters, before authorizing operations to commence. The Environmental Evaluation and Oversight agency (OEFA) monitors environmental compliance.

Mine Closure Process

A mine closure is the process of shutting down mining operations on a temporary or permanent basis. It typically takes two to ten years to shut down a mine, but it can take longer. The mine closure process typically consists of several steps:


  • Shut-down

    Once mining production stops, the workers then decommission the mining processing facilities and equipment. The pipelines are drained, the equipment and parts are cleaned and sold, the buildings are repurposed or demolished, and the waste is properly disposed of.

  • Remediation

    Mine remediation involves a number of activities such as removing equipment and materials, reshaping the land, restoring the topsoil, and planting native grasses, trees or ground cover.

  • Post-Closure

    We use monitoring programs to monitor the area and identify if any additional corrective actions need to be taken. In addition, we provide long-term care and maintenance to the area after each mine closure.

Mine Closure Plans

Mine closure plans are specific to each individual mine. The terms reclamation, remediation, and restoration are all used to describe mine closure activities that aim to return the mined area to its natural state.


At mining sites, remediation often consists of isolating contaminated material in pre-existing tailings storage facilities, capping tailings and waste rock piles with clean topsoil, and collecting and treating any contaminated mine water if necessary.


 Reclamation is the physical stabilization of the terrain, landscaping, restoring topsoil, and returning the land to its natural state.


Restoration is the process of rebuilding the ecosystem that existed at the mine site before it was disturbed. Successful remediation, reclamation, and rehabilitation can result in the timely establishment of a functional ecosystem.
