Commitment, experience and teamwork have been the critical ingredients in a five-year closure program undertaken at Newmont's Tanami operation in the Northern Territory.
Senior Regional Manager for Closure and Reclamation Mike Slight, Closure Superintendent Roger Potts and Outback Ecology Services' Harley Lacy presented to more than 300 delegates at a two-day conference themed, Mine and Industrial Site Remediation for Closure: Tools and Global Case Studies.
Tanami manages one of the largest mine closure programs in Australia, in one of the country's most remote and harsh environments. The site has 45 open pits, eight backfilled pits, 11 in-pit tailing storage facilities, 24 waste rock landforms, two tailing storage facilities, a processing plant and on-site village accommodation.
The program has involved five years of investigative work, planning, earthworks and extensive consultation with local Indigenous groups, government departments and other key stakeholders. The objective is to rehabilitate land to the point it can support sustainable ecosystems. After restoration, the land will be returned to Traditional Owners.
