Bryah Basin Project
The Bryah Basin project is located approximately 100-150km north of the town of Meekatharra in Western Australia. The Company’s tenements cover 718.5km² over parts of the western Bryah Basin. Active and historic mines located close to the Company’s tenements include the Fortnum, Labouchere, Horseshoe, Peak Hill, Hermes and Harmony gold mines and the Horseshoe Lights copper/gold mine.
Historical exploration during the 1980s and 1990s primarily focused on gold targets that could be mined by shallow open pit methods. Deeper exploration was generally limited to the immediate vicinity of the then operating mines. Exploration and mining activity in the Bryah Basin declined substantially during the late 1990s and 2000s.
With the discovery of the DeGrussa copper/gold deposit by Sandfire Resources NL (Sandfire) in 2009, a renewed phase of exploration across the Bryah Basin commenced, targeting deeper volcanogenic massive sulphide (VMS) style mineralisation.
In June 2015 Sandfire discovered the high-grade Monty copper/gold VMS deposit. Details of Sandfire’s exploration results are available online from ASX.
In 2014, deeper drilling by RNI NL (now Auris Minerals Limited AUR) to test beneath the Forrest gold prospect in the western Bryah Basin identified significant copper/gold mineralisation at depth.
In January 2017 AUR announced that aircore drilling at the nearby Wodger prospect had intersected an extensive halo of highly anomalous VMS mineralisation between the Ravelstone Formation sediments and hydrothermally altered mafic volcanics of the Narracoota Formation.
In July 2017 AUR completed an RC drilling programme which recorded a best intersection of 50 metres @ 1.55% Cu. Subsequent drilling at Wodger in 2017 has intersected further zones of copper mineralisation. Further details of AUR’s exploration results are available online from ASX.
The Wodger and Forrest Prospects are located less than 2km west of the Company’s tenements. The Company considers that the recent exploration success at AUR’s Big Billy, Wodger and Forrest prospects is highly encouraging and confirms the excellent potential for similar copper/gold mineralisation to be discovered on the Company’s neighbouring tenements and elsewhere within the western Bryah Basin.
