Yanrey

The Yanrey uranium project located about 85 kilometres south of the north western Western Australian regional centre of Onslow, is an advanced uranium exploration project at the extensive Bennet Well deposit that has been deemed suitable for In-Situ Recovery (ISR) method of mining. The Yanrey uranium project is wholly owned by Cauldron Energy Limited, a company which was previously operating as uranium exploration company, Scimitar Resources Limited.

The Yanrey Uranium Project to be Developed in a Similar way to That of the Manyingee Project

The Yanrey project's Bennet Well highly prospective uranium deposit is hosted in sandstone which is quite similar to the adjacent Manyingee deposit that had been successfully field trialled for In-Situ Leach (ISL) mining in the 1980's

Cauldron Energy Limited Began Exploration of Bennet Well Deposit in 2006

Cauldron Energy Limited began exploration of the Bennet Well uranium deposit in 2006. Its most recent drilling of the resource occurred in late 2014 which resulted in a 16 percent upgrade that indicated the deposit had a total JORC compliant Indicated and Inferred uranium resource of 21.51 million pounds, according to independent mining consulting group, Ravensgate. This result confirmed the Yanrey project as being prospective for large sedimentary-hosted uranium deposits.

Cauldron Energy Limited Operates Mines in Australia and Argentina

Cauldron Energy Limited, is a resource development company based in Perth, Western Australia. It is actively engaged in developing a suite of base metal and uranium projects in Argentina as well as in Australia.

Cauldron Energy Limited to Mine the Bennet Well Deposit Using ISR Mining Technology

The ISR method of mining that Cauldron Energy Limited is planning on using to bring the Yanrey project into production is, in effect, an injected-solution method of mining which reverses the natural process that deposited the uranium in the sandstone host rock in the first place. It involves on-site groundwater, that has been fortified with oxygen gas, being injected into the uranium ore body through a number of injection wells. The injected solution dissolves the uranium from its sandstone rock host. Sandstone host rock is particularly suited to extracting uranium by means of ISR mining methods, in fact, this method of mining uranium has become a well established mining technology.

After the water and oxygen gas solution has dissolved the uranium bedded in the sandstone host, the now uranium bearing solution, is brought back to the surface via a series of production wells. On the surface the uranium is concentrated on resin beads for more processing which involved drying the concentrate to produce yellowcake. The series of injection, recovery and monitor wells at the mine site are known as a wellfield.

The ISR method of mining uranium has been used in many countries since the 1970's and has previously been approved to be used in two locations in South Australia, at the Honeymoon deposit and at the Beverley mine that began mining uranium in 2000.
