The West Bryah Project is located approximately ~140km north of Meekatharra in central Western Australia (refer Figure 3 below). The Project area is accessed by the Meekatharra‑Mount Clere Road, which travels across the western part of the tenement package or alternatively by the Great Northern Highway, then by the Ashburton Downs-Meekatharra Road. The West Bryah Project consists of 7 granted exploration tenements covering a total of 349.3km2. Star has entered into agreements to acquire these tenements from the respective owners.

The tenement package straddles the Meekatharra – Mt. Clare Road, in mostly flat arid country.
The West Bryah Project is located on rocks of the Padbury and Bryah groups (forming the Bryah Basin), a series of sediments (stratigraphy is detailed in the accompanying Independent Technical report) that have been folded and form the northern flank of an antiform centred on Peak Hill (refer Figure 3 below). These rocks are interpreted to be part of a rift-spreading system.
The Padbury and Bryah groups sediments are unconformably overlaid atop the schists and Archaean granitoids and greenstones making up the Marymia and Narryer terranes, with granitoids and Yarlarweelor Gneiss occurring along the edge of the tenement area to the west.
The Bangemall Supergroup sediments are draped unconformably over the Bryah Basin sequence. Two of the major mines of the area, Horseshoe Lights and Fortnum are located near the Fortnum Fault, an east-west trending fault that forms the edge of the Bangemall Basin.
Much of the tenement package is covered with alluvial sediments related to the (seasonal and intermittent) Murchison River system.
This region hosts significant mineral endowment. Currently, the region hosts major mining projects including the Fortnum and Mt Seabrook gold operations and was home to a number of historical gold and copper-gold operations, including Harmony, Peak Hill and Horseshoe Lights.
WEST BRYAH PROJECT GEOLOGY
The Project is an early-stage exploration project which can be characterised as offering potential, but little historical data.
The region was first explored by prospectors during the gold rush period between 1897 and 1911, centred on Peak Hill. Modern exploration began in the 1960s and was undertaken by a range of companies searching for gold, uranium, manganese, iron ore and base metals. Much of this work was soil sampling and shallow Rotary Air Blast (RAB) drilling, and much of it was limited in scope, as other commodities were targeted so no gold assays are available.
Even when gold was the target, much of the drilling was in alluvial cover, with very limited work on the underlying strata. Of the more interesting results, these will be used by Star to provide initial targeting for further investigation, sampling and drilling.
Due to the unproductive nature of much of the previous work, the Company believes that these results were not effective and present an opportunity, as it indicates that more modern and effective methods may show good results. Star believes that the West Bryah project area is prospective for orogenic-style gold deposits, and base metal VHMS deposits that may prove to be economic.
