The Gundjeihmi Aboriginal Corporation was founded in 1995, to act as the vehicle for the collection, disbursement and investment of funds derived from the Ranger Uranium Mine on behalf of its primary stakeholders, the Mirarr clan. The Corporation plays a pivotal role in the management of relations between Mirarr and other Bininj, and between Mirarr and non-Indigenous people (Balanda).

The Corporation operates in accordance with its governing legislation, the Corporations (Aboriginal and Torres Strait Islander) Act 2006. This act replaced the former governing legislation, the  Aboriginal Councils and Associations Act 1976.

It is governed by a Board of Directors, comprising senior members of the clan. It employs some 20 full time staff in a range of positions across the organisation. In addition, through its work crew, it employs on a casual basis up to 50 additional people at any given time.

The corporation also retains a number of advisers on a contractual basis. These advisors come from fields including law, governance, hydrology, linguistics, environmental science and event management.
