The West Angelas Deposit F is located within the Hamersley Basin of Western Australia, which hosts some of the most significant iron ore deposits in the world. Mineralisation at the deposit occurs as bedded mineralisation within the Marra Mamba Iron Formation.

The deposit contains both detrital and bedded-hosted iron mineralisation. It is hosted in the Marra Mamba Iron Formation. The mineralisation occurs primarily within the Mount Newman Member with minor mineralisation within the West Angela Member, MacLeod Member and Nammuldi Member.

The bedded mineralisation is generally overlain by a variable thickness zone of alluvium/colluvium with a weathering overprint.

The existing West Angelas Operations currently consists of:
- Clearing of up to 7,890 hectares (ha) within the existing 22,600 ha Development Envelope.
- Open cut above and below water table mining of iron ore from Deposits A, A west, B, E and F, by conventional drill, blast, and load and haul techniques.
- Ore processing in central processing facilities at approximately 35 Million tonnes per annum (Mt/a).
- Surface waste dumps which are used in backfilling of the pits as far as practicable.

Development of West angelas Mineral Resource assumes mining using standard Rio Tinto Iron Ore equipment and methods similar to other Rio Tinto Iron Ore operations. The assumed mining method is conventional truck and shovel, open pit mining at an appropriate bench height. Mining practices will include grade control utilising blast hole data.

The mine has been designed to transport ore to an existing central crushing and processing facility.

The West Angelas mine has been designed with a dry crush and screen processing facility similar to processing facilities at other Rio Tinto Iron Ore mining operations.

At West Angelas mine, dry crushing and screening is used to produce lump and fines iron ore products.
