The site for Port Spencer is located between Lipson Cove and Rogers Beach, about northeast of the town of
Tumby Bay. The port could be served by a
narrow gauge branchline from
Ungarra on the
Eyre Peninsula Railway.
Lipson Cove lies immediately to the south with the proposed wharf structure 1.5 kilometres north of
Lipson Island Conservation Park. Swaffers Road was marked to become a future haul road. Centrex Metals' preferred method for the long-term transport of ore to the port was via a slurry pipeline. A
desalination plant capable of producing of 5-20 gigalitres of water per year would have been required to provide the water necessary to transport the ore in a slurry to the Port Spencer site. Once the ore was dewatered, it would have been loaded onto conveyors, along a jetty and onto
capesize bulk carrier vessels. An alternative development approach announced in November 2013 proposed the ore to be
trans-shipped from a shorter jetty in barges, each carrying 15,000 tonnes. If such a method were to be employed, 12 barge-loads (round trips) would be required to fill a single Capesize vessel, with a capacity of 180,000 tonnes.
Grain-only revision Free Eyre's 2018 revision of the Port Spencer proposal intends to have grain delivered to the port site by truck, then directly loaded onto
Panamax vessels via a single 600 metre-long jetty. The jetty would be supported by ten pylons, and the total cost of the development was estimated to be $130 million AUD. Project costs had been heavily optimised over several years, down from prior estimates of $300–400 million AUD. In 2020, Peninsula Ports' revised plans for Port Spencer were made available for public comment. , the current planned opening date (according to the official website) is the end of 2026. == Environmental approval processes ==
