The Company’s Bryah Basin and Gabanintha Projects are located in central Western Australia.

The Bryah Basin project is located approximately 100-150km north of the town of Meekatharra in Western Australia. The Company’s tenements and manganese mineral rights cover 1,135km² 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.

Gold and Copper Exploration

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.

The Wodger and Forrest copper-gold prospects held by Auris Minerals (AUR) 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.

In October 2018, Bryah Resources announced that it had discovered multiple zones of gold mineralisation in drilling at the Windalah Prospect (formerly known as the Mars 1 Anomaly), which lies within the Bryah Basin Project.

 High-grade gold mineralisation was recorded in 2 drill holes:

  • BBRC019: 5 metres @ 6.62 g/t Au (79-84m), including 1m @ 15.05 g/t Au (82-83m)
  • BBRC020: 2 metres @ 3.39 g/t Au (78-80m), 4 metres @ 2.72 g/t Au (134-138m), and 3 metres @ 6.69 g/t Au (145-148m) including 1m @ 10.52 g/t Au (146-147m).

In May 2020, a short RC drilling program of 210 metres consisted of 3 holes (BBRC047-BBRC049) was drilled to test for shallow extensions of the gold mineralisation intersected in 2018.

The best result was:

  • BBRC049: 12 metres @ 4.32 g/t Au from surface, including 2 m @ 17.19 g/t Au from 3 metres

Follow-up drilling was undertaken in the second half of 2020 to test this exciting gold prospect.
