The MIB is closely linked to the Yinhawangka through marriage and close family ties, as well as through common political experiences. Conversely, the connection between Yinhawangka and the main MIB family is also reflected in the tension they share with the main Top End Banyjima family and the Eastern Kurrama. This tension is reflected not only in discussions about country and group membership, but also in the organizational tensions between Gumala and IBN Corporation, described below. The role of the individual is clearly an important factor in the relationship between the mining industry and indigenous organizations such as Gumala and IBN Corporation. The first president of Gumala and founder of IBN Corporation at the time of this study received significant support from the Pilbara mining industry through his role in the YLUA negotiations, then by the companies Gumala and IBN. He is considered an Aboriginal entrepreneur and has been supported by a number of non-Aboriginal people who are involved in the political landscape of Pilbara. His ability to attract people around him strained relations between IBN Corporation and Gumala. Clive Senior, employed by Hamersley Iron as a mediator during the YLUA negotiations, was hired directly by IBN Corporation as a negotiator for the Area C agreement. In 2005, senior served on the board of directors of IBN Corporation (IBN Corporation/Indigenous Mining Services 2004). In addition, Ian Williams, a former Rio Tinto employee who participated in YLUA negotiations and century mine negotiations in Queensland, also served on the board of directors of IBN Corporation (IBN Corporation/ Indigenous Mining Services 2004). John Cunningham, President of the Polly Farmer22 Foundation and a former collaborator of Conzinc Rio Tinto of Australia (CRA), served on the boards of Gumala and IBN Corporation (IBN Corporation/Indigenous Mining Services 2004). In addition, a number of Aboriginal people, who are important in regional policy, are two members of the board of directors of both organizations. A number of individuals representing language group companies within the ibn Corporation structure are also involved in Gumalas` affairs as general members of the organization and members of the board of directors.
