Summary:

Geological Setting
Geologically, the Restart Area domains are situated above the Paleoproterozoic-aged Willyama Supergroup which began forming approximately 1700 million years ago (Ma) and comprises a thick (~7000 – 9000 metres) sequence of deformed volcanics and metasediments. Subsequent periods of regional-scale tectonic activity, rifting and formation of inland seas led to the eventual deposition and faulting of the Bulldog Shale. Around the beginning of the Palaeogene (approx. 65Ma), regional crustal subsidence was once again initiated, reactivating fault structures in the Bulldog Shale and resulting in the creation of the large-scale Lake Eyre Basin (LEB). The LEB extended from Central Australia to central Queensland to central South Australia and involved three distinct phases of sedimentation and changes in climate from a largely tropical, wet environment to the current arid conditions. The first phase of sedimentation is represented by the Eyre Formation, deposited between the Late Eocene to Early Oligocene (~41Ma to ~27Ma), that marked the initiation of active river systems eroding into the exposed saprolitic surface of the Bulldog Shale.

The base of the Eyre Formation is represented by large pebbles and gravels in coarse-grained sand, often containing a clay-rich matrix between larger rock fragments of eroded Bulldog Shale, broken off by large, fast-flowing rivers (e.g. the Yarramba and Billeroo Palaeovalleys that host the Honeymoon Re ........


Mining Methods

  • Solution mining


Summary:

In-Situ Recovery (ISR)
ISR is the preferred, and most cost effective and environmentally acceptable, method of mining for the Honeymoon uranium resource. ISR is a proven extraction process which accounts for approximately 55% of world uranium mined, and is predominantly used in Australia, USA, Kazakhstan, and Uzbekistan. The ISR process involves the installation of multiple wells in a specific pattern over the orebody. For each pattern a bore, or well, is drilled in the centre of the pattern and installed with a borehole pump. This is designated the extractor well. Four to six additional wells are drilled around the extractor to form the injector wells. Each well is cased with PVC casing and includes a slotted screen installed at the depth of the orebody. The length of the screens is specific so as to cover the thickness of the mineralisation. The casing is cemented in place, isolating the ore horizon and preventing the potential loss of any mining fluids once production has commenced. Pipework is installed to connect the injector and extractor wells to the main processing plant. A wellfield can be made up of up to 16 extractors and 25 injector wells. Additional wellfields are subsequently installed with similar patterns over the rest of the orebody, until the entire deposit is covered.

When mining is initiated, a leaching fluid (the “lixiviant”) is pumped into the orebody through the injector wells. The lixiviant moves through the ore within th ........
