Tanami mine site, located in one of the most remote and inhospitable locations of Australia, is undergoing
one of the largest mine closure works programmes seen in Australia over the past five years. The mine area
and its satellite pits are scattered over an area of 100 km in length and 1800 km2 within the Tanami Desert
of the Northern Territory, approximately 670 km north-west of Alice Springs, and is one of the most remote
mines in Australia. The majority of the project area occurs within the Central Desert Aboriginal Land Trust,
administered by the Central Land Council (CLC).
The site is a historic mining area which was mined for gold from the early 1900s and, most recently, from
the mid 1980s, up until 2004. The site comprises 45 open pits, eight backfilled pits, 11 in-pit tailing storage
facilities, 24 waste rock landforms, two above-ground tailing storage facilities (TSFs), a processing plant
and on-site village accommodation. The site is in the final phase of closure works after five years of
investigation work, planning and earthworks. Consultation with local indigenous groups, government
departments and other key stakeholders has facilitated a transparent closure process towards the agreed
return to traditional land-use. The final land-use objective for the Tanami Mine is for rehabilitation of the
mined environment to occur over the long term to promote the establishment of sustainable ecosystems.
Following the demonstration of rehabilitation and the achievement of lease relinquishment, the area will be
returned to the site’s traditional owners for traditional uses.
The harsh environmental conditions of cold winters, extreme summer temperatures, highly variable rainfall
(from occasional drought to intensive, short duration cyclonic rainfall), frequent wildfires and remoteness
are some of the many challenges faced during the closure process. The size of the site and array of
landforms, some composed of highly unstable and dispersive waste material, further complicated the closure
process. The progress of the Tanami mine closure works programme to date is largely the result of effective
interaction between an experienced closure and reclamation team, as well as a committed and engaged
workforce. The management team provides leadership in planning, design, execution, environment, safety,
community relations and cost control to assist and engage the workforce.
