The Byro Uranium Project is located 300 km NNE of Geraldton, and contains gneiss and migmatite, greenstone belt volcanics, sediments and typical Yilgarn granitoids of the Murchison Province. The project consists of two tenements E20/693 and E59/1617, covering an area of  1,078 km2. 

The focus of this project is to discover a substantial calcrete hosted uranium deposit within or adjacent to the Murchison River on E20/693. GSWA radiometric data shows a prominent NE trending linear uranium anomaly, some 45km long and 4 - 5 km wide, flanking the Murchison River.

Mapping by the GSWA also shows the radiometric anomaly to be largely coincident with extensive areas of mapped calcrete. The Company intends to commission a detailed airborne radiometric survey to better define the higher grade portions of the extensive channel. Processing of radiometric data will generate specific targets for ground follow up once the tenements are granted.

The Yelma Sandstone at the base of the Nabberu Basin is overlain by the Frere Formation, which contains cherty and iron rich chemical sediments, carbonates and clastic sediments. These iron rich sediments within the licence application area may be the protore for interpreted channel iron deposits.The lower iron formation (Granular Iron Formation or “GIF”) is granular in texture and resembles the iron formations found in the Lake Superior region of North America.  The upper unit is Banded Iron Formation (“BIF”) with some similarity to the Hamersley Basin BIF’s, and consists of purple to black finely laminated hematitic chert up to 150m thick which is, in places, interbedded with minor GIF and thin shale units.

The Hamersley Basin iron ores are considered to have originated as a result of the leaching of impurities by ground water from BIF to produce nearly pure iron oxide. Weathering of pre-existing iron ore some 20 to 30 million years ago has resulted in the formation of valley fill “channel iron deposits”. These usually consist of goethite and hematite with minor amounts of silica and clay. Goethite pisoliths with hematite cores are commonplace. Uplift and erosion has exposed the channel deposits in places such as the Yandicoogina mine.

Enterprise has imaged processed and interpreted GSWA supplied 400 metre line spaced airborne magnetics for the Earaheedy 1:250,000 map sheet. The BIF’s of the Earaheedy area are characterised by strong E-W linear magnetic responses. Enterprise’s tenement application overlies a series of major magnetic palaeo-channels draining south easterly from the BIF’s of the Lee Steere Ranges. These interpreted channels potentially host channel iron deposits of significant tonnage.

When the tenements are granted, it is planned to fly a detailed magnetic survey over the channel areas, and conduct detailed gravity surveys to define RC drill targets.
