The Durack deposit is situated on cleared freehold land just 5km from a sealed road connecting Eneabba and Three Springs. It is 170km by road from Geraldton Port and 25km south of the Yandanooka prospect. Durack is situated on tenement E70/3762.
The deposit is interpreted as a broad-dunal style heavy mineral accumulation, with heavy mineral concentrations deposited preferentially against a basement barrier developed parallel to the Urella fault extensions. The deposit is similar to that of Sheffield's Yandanooka deposit.
On 01 October 2018 Durack Mineral Resource was revised to be compliant with JORC 2012 Reporting Code. Durack (at a 1.4% HM cut-off) has a Mineral Resource of 26.3Mt @ 2.8% HM, with an indicated component of 20.7Mt @ 2.9% HM, and an inferred component of 5.6Mt @ 2.6% HM.
Contained valuable heavy mineral (VHM) at Durack totals 681kt comprises of 523kt of ilmenite, 104kt of zircon, 21kt of rutile and 33kt of leucoxene. This includes an indicated 551kt of contained VHM comprising of 429kt of ilmenite, 82kt of zircon, 18kt of rutile and 22kt of leucoxene, and an inferred 130kt of contained VHM comprising of 95kt of ilmenite, 21kt of zircon, 4kt of rutile and 11kt of leucoxene.
The strike length at Durack is 5,000m with across strike width of 1,500m and average thickness of 6m. Mineralisation is from surface to a depth of 16.5m (see Mineral Resource and Ore Reserve Statement, ASX release 03 October 2018).
In 2014 a bulk sample was assembled from drill samples (150kg) for characterisation test-work. This concluded that Durack HM is amendable to typical mineral sands processing methodologies using standard mineral sands separation equipment.
