Based on the updated Ore Reserves estimate above, as at 31 December 2021, current remaining Ore Reserves at Boonanarring is scheduled to be depleted in Q1 2023, following which, the wet concentration plant will be relocated to the Atlas Project, where it will be operated on current Atlas Ore Reserves and any newly identified Ore Reserves in the Atlas area. |

Summary:
The Boonanarring deposit is located on the Dandaragan Plateau and Swan Coastal Plain, to the west of the eastern edge of the Swan Coastal Plain, where the footslopes of the Gingin Scarp rise steeply to the Dandaragan Plateau. The local area comprises several surface geology units, however the Premises itself is predominantly located on the sand plain surface geology unit to the east of the Brand Hwy and the Gingin Scarp, and a smaller portion on the Bassendean Sand unit to the west.
The stratigraphic sequences relevant to the Boonanarring include the Quaternary aged Colluvial/Bassendean Sands and Guildford Formation, the Late Tertiary Yoganup Formation and the Mesozoic Leederville and Yarragadee Formations. All of these surficial geological formations have either been formed or have been strongly influenced by marine regression and transgression events since the Early to Mid-Tertiary (approx. 50 million years ago).
The Leederville and Yarragadee Formations, which typically forms the base of mineral sand operations on the Swan Coastal Plain, consists of interbedded, weakly to well consolidated sandstone, siltstone, shale and claystone that, in the upper portions, have been deposited in a non-marine, primarily fluvial setting. The Leederville Formation sediments conformably overlie the Yarragadee Formation. The mineralised sands of the Yoganup Formation unconformably overlie the Mesozoic Formations, and consists primarily of friable ‘beach’ sands which wer ........

Summary:
The mining and support earthmoving activities will be delivered under a Contract Mining Agreement, where the mining contractor will be responsible for all mining and associated earthworks using a standard Schedule of Rates contract incorporating normal dayworks provisions. Image will be responsible for statutory duties, technical services, potable water, power and dewatering operations.
Scrapers and/or excavators and trucks will be employed to mine the ore to a stockpile located at the SMU. A Cat 988 loader or similar will then feed the SMU from the stockpile at a rate of 500 t/h. Using this type of fleet will give flexibility for ore blending, not only when mined but also off the stockpile at the SMU. In addition, use of this method will mean the SMU can stay in one place for up to 12 months, which will minimise downtime due to SMU relocations.
The Boonanarring deposit is split into two strands; East and West. The eastern strand is generally higher in heavy mineral content than the lower grade western strand. To get consistency of the grade of the ore being fed to the WCP, the eastern and western strands will be blended. Ore feed has been constrained to a maximum of 500 t/h at 85% utilisation of SMU feed. This will be the primary production constraint.
Following initial pit establishment, the mine void will be progressively backfilled with overburden, sand tailings and clay fines. Dry clay from solar drying ponds will be mixed into the upper ........
