Bryah Resources Limited is pleased to announce the results of leaching testwork undertaken on samples from the Windalah Gold Prospect (“Windalah”), located within its Bryah Basin Project, approximately 140 kilometres north of the town of Meekatharra in central Western Australia (see Figure 1).
- Average of 94% gold recovery from cyanide leaching testwork of 15 samples from hole BBRC049 (0-15 metres depth)
- High-grade gold interval reported as 12 metres @ 5.13 g/t Au from surface, including 2 metres @ 21.48 g/t Au from 3 metres in latest testwork
- Total gold assay results correlate well with initial laboratory analysis
- Results from follow-up gold drilling program expected this week
Bryah Resources recently announced Reverse Circulation (RC) drilling results from 3 drill holes (BBRC047-BBRC049) (see Figure 2) at Windalah1, with drill hole BBRC049 reporting the best gold interval of:
- 12 metres @ 4.32 g/t Au from surface, including 2 metres @ 17.19 g/t Au from 3 metres.
To confirm this result, 15 one metre residual drill samples from BBRC049 (0-15m depth), were delivered for testing for gold recovery by cyanide using a 6-hour bottle roll leach test at a laboratory in Perth.
The results from this testwork confirmed and increased the overall grade of the gold mineralised interval in BBRC049 (using a 0.5 g/t Au cut-off grade) to:
- 12 metres @ 5.13 g/t Au from surface, including 2 metres @ 21.48 g/t from 3 metres.
The samples also recorded an average of 94% gold recovery using cyanide leaching. This is a very positive result, demonstrating the potential gold recoveries from Windalah using conventional cyanide leaching.
Bryah Resources has recently completed further drilling at Windalah with the results of seven holes (BBRC052-57 and BBRC060) due to be received later this week.
Commenting on the leaching results, Managing Director, Neil Marston said:
“We are delighted with these test results. These results confirm and increase the high-grade gold interval which was reported previously for hole BBRC049. Overall, the mineralised zone is 12 metres at 5.13 g/t gold from surface in this drill hole.
A very high-grade interval within this gold mineralised zone, which we originally reported as 2 metres @ 17.19 g/t gold from 3 metres, using conventional fire assay techniques, has reported an even higher grade of 2 metres @ 21.48 g/t gold from this bulk leaching testwork.
These results support our view that the gold from Windalah will be amenable to processing using conventional cyanide leaching techniques.
We have completed a follow-up drilling program at Windalah last month and expect to receive the assay results for seven new drill holes from the laboratory later this week.”
