Rio Tinto has signed a major land use agreement with the Yinhawangka people in the central Pilbara.
The Yinhawangka are the traditional owners of about one million hectares of land which Rio now has access to for the entire span of its iron ore mining activities in the area.
In return, the Yinhawangka will receive a percentage of Rio's earnings as well as employment and training opportunities.
The Yamatji Marlpa Aboriginal Corporation's, Michael Meegan, says all parties are happy.
"There will be significant financial benefits, now and in the future for future generations," he said.
"Importantly, for the traditional owners was some critical issues in relation to quarantining important places, important sites, places that have traditional and cultural significance."
Mr Meegan says it is a wide-ranging agreement.
"Rio will work with the groups to help the members get jobs," he said.
"The agreement also provides cultural benefits, consultation about our cultural heritage.
"Rio Tinto's agreed to provide tenure support for a number of communities within the Yinhawangka native title claim area."
