Pilbara Hub deposits including Iron Valley, Wonmunna, Lamb Creek are classified as Bedded Iron Deposit (BID) deposits in the Hamersley Province. The province consists predominantly of late Archean and Lower Proterozoic sedimentary rocks of the Hamersley Basin situated between the Archean Yilgarn and Pilbara cratons.Iron ValleyMineralisation within the Iron Valley deposit occurs as outcropping and buried BID and Detrital mineralisation (DID). Outcropping geology in the project is the Joffre Member of the Brockman Iron Formation which hosts the BID mineralisation (predominantly in the upper Joffre member). Incised into this bedrock geology are deposits of DID mineralisation. The Weeli Wolli Formation also outcrops in the area, as well as Wongarra volcanics, Quaternary colluvium and a dolerite dyke.The Iron Valley deposit extends approximately 6 km along a strike of 030°. The width varies from 50m to over 600m. Thickness varies from <15m to >120m. WonmunnaThe Wonmunna Iron Ore project is situated within the late Archaean to early Proterozoic (2765-2470 Ma) Hamersley Basin which unconformably overlies the southern extent of the Archaean Pilbara Craton. The main lithologies within the project area are banded iron formation (BIF) and shale of the Marra Mamba Iron Formation; and shale and dolerite of the Jeerinah Formation. The main mineralisation within the Wonmunna area is a BID situated in the Nammuldi Member of the Marra Mamba Iron Formation. The mineralisation is comprised of bedded goethite, martite and limonite. The BID occurs as an E-W trending orebody, it is discontinuous across 4km in length, with a maximum width of approximately 440m and extends to depths of up to 90m below surface.The Wonmunna Iron Ore Project BID occurs as an E-W trending orebody, it is discontinuous across 4km in length, with a maximum width of approximately 440m and extends to depths of up to 90m below surface. Mineralisation lies between 735mRL and 645mRL. The hydrated BID (HYD_BID) has a maximum thickness of 18m and an average thickness of 5.5m. The primary mineralisation (BID) has a maximum thickness of 48m and an average thickness of 11m. The mixed BID (MIX_BID) has a maximum thickness of 20m and an average thickness of 5.4m. Lamb CreekThe Lamb Creek Prospect consists of high-grade BIF derived Brockman style mineralisation (BID) hosted primarily in Dales Gorge Member with minor mineralisation occurring within overlying Whale Back Shale and underlaying Footwall zone. The upper part of the mineralisation is hydrated by secondary processes. Mineralisation extends over an area of approximately 1300m NE-SW by 400m NW-SW.The Lamb Creek mineralisation (Fe = 50%) is hosted across all the bedded Members and separately within the Tertiary Detrital Unit. The mineralisation strikes north-east across the tenement, gently dipping to the north-west. The detrital mineralisation has an approximate strike length of 900m, a width range of 250m - 350m, and thickness ranging from 10m – 20m. The BID mineralisation has an approximate strike length of 1,100m, a width range of 250m – 450m, and a thickness ranging from 40m – 70m.
