SnapshotSouthdown is an advanced project with access to established infrastructure. The current project base case is to produce 5 Mt of high-grade magnetite concentrate per annum with scalable options to produce up to 10 Mt per annum.

During 2022, the Company commenced a Definitive Feasibility Study on the 5 mtpa development case and is further progressing designs for the optimised site layout, mine designs, metallurgical test work and pilot plant trials utilising dry grinding techniques, and port operations and transhipping methodology. Progress on the DFS is under review.

Grange Resources’ referral for modifications to the already approved Southdown Magnetite Project was submitted on 30 January 2023 to the Environmental Protection Authority (EPA) for environmental assessment. A new environmental approval will also be sought for the transhipping component of the project by the Southern Ports Authority.

Deposit type

  • Orogenic

Summary:

The Project is located ~90km northeast of Albany in the southwest corner of Western Australia. The Southdown deposit extends approximately 12km in length, under Mining Lease and Retention Licence covering an area of more than 120 square kilometres on largely freehold farming property.

The Southdown deposit occupies the core of a gently east plunging, overturned tight isoclinal syncline with a steeply south dipping axial surface. The deposit is offset by moderately northeast dipping dextral reverse faults and subsidiary steeply south-east dipping sinistral faults.

The defined Resource extends over 11 kilometres of strike, with variable depths ranging from 50 metres below surface in the west to 555 metres below surface in the east.
