Bryah Resources has significantly increased its land holding at its flagship Bryah Basin Project in Western Australia. The newly acquired tenements are located on the western side of the Padbury and Bryah Basins.

Approximately 255 squared kilometres of highly prospective ground has been secured by the recent grant of two new exploration licences (E52/3700 and E52/3726) and the application for a further three exploration licences (E52/3703, E52/3725 and E52/3739). The two newly granted tenements cover a total of 83 kilometres and the applications cover a further 172 kilometres.
The tenements cover more than 50 squared kilometres of the highly prospective Narracoota Formation, including over 40-line kilometres of the prospective strike contact between the Narracoota Formation and the Proterozoic metasediments of the Padbury Basin, with the Narracoota Formation reported to be the same prospective stratigraphy which hosts Sandfire Resources’ currently operating, high-grade DeGrussa copper-gold mine and the historic Horseshoe Lights copper-gold mine.
Mineralisation within the Bryah Basin mainly comprises orogenic lode-gold and volcanogenic massive sulphide (VMS) copper-gold deposits. To date, the majority of exploited gold mineralisation occurs in structurally controlled, mesothermal, epigenetic lode systems.
The tenement package covers under-explored ground south of the historic Labouchere and Nathans gold mines which were mined by Dominion Mining between 1989 and 1992.
Combined historical gold production from the Labouchere and Nathans mines was 222,000 ounces of gold from 2,910,800 tonnes of ore grading 2.4 g/t Au. The Labouchere and Nathans mines are now held by Westgold Resources.
Further to the south, and adjacent to newly granted E52/3700, lies the Wilthorpe gold mine where shallow open cut mining by Dominion Mining Limited in 1993-94 produced 4,650 ounces of gold from 72,817 tonnes of ore grading 2.0 g/t Au.
On the largest exploration licence application, E52/3739 (117km2), historical shallow gold workings at the Top Dimble Prospect and surrounding areas have been the subject of limited gold exploration in the 1980s and 1990s.
Commenting on the acquisition, Managing Director Neil Marston said that Bryah and Padbury Basins remain largely under-explored, with historical exploration activities focused on identifying shallow gold mineral resources suitable for open pit operations.
“With our excellent knowledge and experience of operating in the area, we believe that these newly acquired areas could yield some early exploration success,” added Mr Marston.
