Pit lakes are a common post-closure feature at mine sites and are developing with increasing frequency worldwide following closure of open pit mines.

Due to the oxidation of exposed sulphide minerals on pit walls, and to the flushing of soluble metals during pit filling, many pit lakes are characterized by poor water quality.

Given the implications for environmental protection, regulatory compliance and potential long-term liability of pit lakes, considerable attention has been given to their management, characterization and remediation.

Lorax Environmental has considerable expertise in developing defensible and practical management plans for pit lake systems. Such plans have formed significant components of closure planning for mining operations in Canada, South America, U.S.A and Southeast Asia.

For the successful development of pit lake management strategies, Lorax relies on seamless integration of several areas of expertise including:
