85km south of Onslow in the northwest of Western Australia
11 granted exploration tenements totalling 1,050 km2 plus 1 application for an exploration licence (220 km2) for a total project are of 1,270 km2 in Western Australia.
Yanrey is prospective for large sedimentary-hosted uranium deposits and is host to the Bennet Well Uranium Deposit.
Tenements overlie Mesozoic sediments highly prospective for sandstone hosted uranium mineralisation, amenable to In-situ Recovery (ISR) mining.
Mineralisation at Bennet Well is a shallow accumulation of uranium hosted in unconsolidated sands (less than 100 m downhole depth) in Cretaceous sedimentary units of the North Carnarvon Basin.
- Total uranium resource of 38.9 Mt at 360 ppm eU3O8, for total contained uranium-oxide of 30.9 Mlb (13,990t) at 150 ppm cut-off. Preliminary economic evaluation has shown that a 150ppm eU3O8 average grade over at least half a metre is potentially economic for ISR type uranium production at the Yanrey Project
- Tenements lie within an area historically proven to host significant uranium deposits, evidenced by the Manyingee uranium deposit (as at 15 August 2015), which has a published indicated resource of 15.7 million pounds at a grade of 850ppm U3O8 and an inferred resource of 10.2 million pounds at a grade of 850ppm U3O8
- Targeted exploration has allowed Cauldron to clearly identify the increasing potential to further establish uranium resources at the Yanrey Project with multiple prospects over its large tenement holding.
- Cauldron has not undertaken field work at Yanrey Project since the announcement on 20 June 2017 of a ban of new uranium mines in Western Australia by minister Bill Johnston. The policy heading for uranium exploration in Western Australia remains unclear at this time.
