The WA Department of Mines, Industry Regulation and Safety granted mining licences for a period of 21 years over the Robe Mesa and P529 deposits, which sit next to the massive Robe River joint venture over the Robe Valley channel iron deposits.
Rio Tinto's Mesa F project is also nearby.
Robe Mesa has mineral resources of 45.2 million tonnes grading 56% iron.
CZR is developing the project as part of an 85:15 JV with Creasy Group-subsidiary Zanf.
With Mesa A, B, C, H and J used by Robe River and extensive drilling underway at Mesa F, CZR's Robe Mesa deposit is essentially surrounded.
Robe Mesa will target 3.5 million tonnes per annum, shipping from export facilities at the Port of Ashburton.
CZR managing director Stefan Murphy said the granting of the mining licences was a watershed moment.
"CZR has a clear strategic goal to grow the size and forecast production rate from the Robe Mesa iron ore project, to make it resilient throughout the economic cycles and a more valuable asset for CZR and its shareholders," he said.
"The granting of mining licences covering the Robe Mesa deposit, following a collaborative agreement with the Robe River Kuruma Traditional Owners, has been a goal of CZR for many years and further de-risks our project, adding value to the Robe Mesa asset."
Murphy said iron ore was largely driven by logistics and marketing.
"CZR has shown over the past month that much of the hard work behind the scenes is beginning to pay off with the pit-to-port value chain taking shape and bolt on acquisitions secured to further enhance our project scale," he said.
"The mine plan will target a production rate of 3Mtpa of direct shipping ore fines of similar specification to Rio Tinto's Robe Valley fines, produced at the adjoining Mesa A and Warramboo mines."
