Key Projects


Mn Energy’s Manganese Processing Plant (MPP) Project is currently under feasibility study to start constructing a Manganese Sulphate Plant. The proven technology we have in addition with the new IP will develop the Lithium-Ion Battery Industry and assist the Agriculture Industry within Australia.

Our project will create over 100 construction and 32 new full-time jobs that will be directly involved in the processing plant. It will also be creating and supporting jobs in the transport industry. Our ore supply will be transported daily from the Meekatharra area to the plant, as well as the transport of reagents and final product. The project will support the chemical industry as we seek the necessary products from local suppliers in the Kwinana/Rockingham area.

More jobs will be created once we complete Phase 2 and enter into the production of cathode materials.

MPP Project Phase 1

The first phase of the MPP project will be to construct and begin production of our Manganese Sulphate. We plan to be the highest quality producer in the world. Manganese Sulphate is a critical component to the cathode structure of the Lithium-Ion Battery. Due to it’s low cost it is often looked over, however it’s low cost is what makes it appealing to the end product customers.

Mn Energy’s goal is to make the highest purity MnSO4 for our customers to support a lower cost to the consumer for the Lithium-Ion Industry.

Mn Energy is also committed to contributing to our Australian Farmers by providing 20,000tpa of Fertiliser Grade to the Agriculture Industry. Currently 30,000tpa are imported to Australia per year with the market growing. Manganese Sulphate is essential to help produce photosynthesis in plants.

MPP Project Phase 2

Phase 2 of the MPP Project will require a small capital investment for an addition to our plant. As Nickel Sulphate, Cobalt Sulphate and Lithium Hydroxide starts to enter production in WA, this small investment will allow us to produce the highest quality of Nickel /Manganese / Cobalt Oxide (LiNiMnCoO2) together with Lithium Manganese Oxide (LiMn2O4) cathodes on our premises in East Rockingham.

The addition will allow PMG to produce the cathode structure to the request of the customer. Currently the preferred structures of NMC are Nickel-8 Manganese-1 Cobalt-1, Nickel-6 Managnese-2 Cobalt-2 and Nickel-5 Manganese-3 and Cobalt-2.

LMO is currently being researched to be the preferred cathode structure as the end customers seek to find a cheaper alternative to Cobalt, currently the structure sits at Lithium Hydroxide-1 and Manganese-2.
