Government judged companies seeking the bauxite deposits until 1968 when they signed an agreement with Nabalco. In response to the land lease, the Yolngu people challenged Nabalco in what would be the first Aboriginal land rights case: Milirrpum v Nabalco. The case was judged by Justice Blackburn who ruled against the Yolngu people. Bauxite mining in Gove started in that same year in 1971. In 2001, the Gove mine was purchased by Alcan, who in 2002 renamed Nabalco to Alcan Gove. Rio Tinto then bought Alcan in 2007 for $38.1 billion and was renamed Rio Tinto Alcan. Since, Rio Tinto has formed the Gove Traditional Owners Agreement under the Aboriginal Land Rights (Northern Territory) Act 1976, the first negotiated agreement over the Gove mine. Bauxite mined from Gove was refined at Rio Tinto's Gove refinery until 2014, when costs led to the refinery closing. While this has had an impact on employment in the local town of Nhulunbuy, bauxite production has been largely unaffected due to proximity and high export demand from China. Rio Tinto is predicting that their Gove mining operations will finish in 2030. Huntly Mine Huntley Mine is located in the Darling Ranges area near Dwellingup in Western Australia and is currently owned by Alcoa of Australia Limited. Huntly mine produces approximately 25 million tonnes of bauxite per year with an alumina percentage of approximately 32.7%. Despite the relatively low grade ore, bauxite mined at Huntly is low in silica, an impurity, which allows for cheaper production of refining. Bauxite mined at Huntly mine is transported to either the Pinjurra Alumina Refinery by an overland conveying system or the Kwinana Alumina refinery by conveyor and rail. The Huntly mine is situated in the Jarrah forest. In 1961, Alcoa obtained a mineral lease ML1sa, which provided them access to bauxite ores in certain areas of the Jarrah forest. Huntly Mine was not established until 1976 and was the second mine in the Darling Ranges, following the Jarrahdale mine started in 1963. Following restoration efforts at Jarrahdale prompted by the government, restoration efforts for both Huntly and Willowdale Mines were implemented and refined over time. This is largely due to public pressure and restoration technology advancements which have led to tighter legislation. Mining operations at Huntly are currently monitored by the Mining and Management Program Liaison Group (MMPLG), a group of government representatives who approve mining plans. Willowdale Mine
