Bryah Resources Ltd (ASX:BYH) achieved 94% gold recovery in test-work undertaken at Windalah gold prospect within the Bryah Basin Project near Meekatharra, Western Australia.

Test work has been completed on 15 samples from hole BBRC049, which recorded the ‘best’ gold interval of 12 metres at 4.32 g/t from surface, including 2 metres at 17.19 g/t gold from 3 metres.

To confirm this result, 15 1-metre residual drill samples from BBRC049 (0-15 metres depth), were delivered for testing for gold recovery by cyanide using a 6-hour bottle roll leach test at a laboratory in Perth.

“Delighted” with test 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 has reported an even higher grade of 2 metres at 21.48 g/t gold from this bulk leaching test work."

Shares have been as much as 9% higher to 6 cents.

Support view of processing ability

Marston said: “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.”

The results from this test-work confirmed and increased the overall grade of the gold mineralised interval in BBRC049 (using a 0.5 g/t cut-off grade) to 12 metres at 5.13 g/t from surface, including 2 metres at 21.48 g/t from 3 metres.

The samples also recorded an average of 94% gold recovery using cyanide leaching, which is a positive result demonstrating the potential gold recoveries from Windalah using conventional cyanide leaching.

Further drilling results

Samples were tested for gold recovery by cyanide using a 6-hour bottle roll leach test at Intertek Australasia’s laboratory in Perth.

The sample bags containing all the residual RC samples from the drilled metres were recovered from site and delivered to Intertek for analysis by their LeachWELLTM technique.

The full bags, weighing about 20 kilograms each, were crushed and split to produce a 1,000-gram sample for testing.

Bryah has recently completed further drilling at Windalah with the results of seven holes (BBRC052-57 and BBRC060), which are due to be received later this week.
