Bryah Resources has recorded manganese levels up to 49% in rock chip sampling at the Bryah Basin manganese project, leading it to define a series of new targets.  

Bryah (ASX:BYH) recently completed geological mapping of untested areas at the Brumby Creek prospect, with sample results confirming the presence of outcropping and detrital high-grade manganese as high as 49%.

A major gradient array IP survey is currently underway, and follow-up reverse circulation drilling is scheduled for Q3 of this year.

All activities are fully funded by Bryah’s joint venture partner OM Manganese, a subsidiary of OM Holdings. OM is earning up to a 51% stake in the project and currently owns 40%. Bryah remains JV manager until OM earns the majority project stake.

Managing director Neil Marston said the results were an exciting development for the pair.

“Bryah controls over 70km of the manganiferous Horseshoe Range. This mapping program has covered only a small part of the prospective Horseshoe Range,” he said.

“At Brumby Creek, which had not been extensively examined earlier, the sample results are very encouraging with up to 49% manganese recorded in this latest program.

“A 2020 IP survey trial was successful in identifying manganese mineralisation under shallow cover at Brumby Creek. With the recent IP survey confirming mineralisation there is considerable scope for utilising this technique, in conjunction with geological mapping, to continue to add new manganese targets.

“A new IP survey has commenced this week to follow up the mapping program, and to identify new targets for drilling later this year. Recent core scanning results confirmed the presence of some exceptionally high-grade manganese in this part of the Bryah Basin.”

Marston said Bryah was working with its JV partner to determine the best method of material beneficiation into a quality manganese ore product.

“We see great potential for us to be producing high-grade manganese ore from the Bryah Basin in the near future,” he said.

Following up

A series of activities are planned for the coming weeks, including metallurgical testwork on a variety of core samples from diamond drilling completed in January.

This work aims to define the optimal processing method for producing high quality manganese ore. Previous core scanning revealed manganese grades greater than 40% in several drill holes.

Bryah also intends to work towards mineral resource estimates for the Brumby Creek, Black Hill and Horseshoe South deposits.

A heritage survey to clear new areas for drilling has been booked for late July, while RC drilling to test new areas identified by the gradient array IP survey currently underway, as well as step out resource drilling, is booked for Q3.

Bryah yesterday announced a 119% resource increase to its Gabanintha nickel-copper-cobalt resource.

The company is also targeting copper at the Bryah Basin project, with drilling and survey now underway targeting an exciting VMS-style copper-gold target.

The JV agreement with OM at Bryah Basin applies to manganese rights only.
