Bryah Resources’ (ASX: BYH) has extended known manganese mineralisation at the Horseshoe South prospect within its Bryah Basin project in Western Australia.
The company has now received assays from the phase two reverse circulation program completed at Horseshoe South, which included a series of holes drilled into the main pit.
Within the main pit, better intervals were 3m at 33.8% manganese, 5m at 24.2% manganese, and 4m at 25.8% manganese.
Meanwhile, in the extended area, highlight intersections were 9m at 22.6% manganese and 8m at 22% manganese.
“These final results from the historic Horseshoe South manganese mine confirm the potential for zones of high-grade manganese mineralisation to be present just below the existing open pit surface,” Bryah managing director Neil Marston said.
“We have intersected what we consider to be remnants of high-grade channel manganese with this program.”
Mr Marston added the company has also extended manganese zones within the extended pit area.
“This drilling is a further demonstration of the potential to discover new manganese mineralisation from surface and under shallow cover within our project area,” he said.
Manganese drilling program
The phase two reverse circulation drilling program across the Bryah Basin project comprised 83-holes for 2,081m across Brumby Creek, Black Hill, Black Caviar and Horseshoe South.
According to Bryah, Horseshoe South hosts two historic mine pits – the main pit and the smaller extended pit, which is close to the mining lease’s southern boundary.
Across Horseshoe South, the second phase campaign comprised 34-holes for 666m.
OM Holdings earning manganese rights
Drilling for manganese has been undertaken as part of a joint venture agreement inked in April between OM Holdings and Bryah.
Under the agreement, OM will spend $7.3 million via a staged earn-in on exploring and advancing the project’s manganese potential.
OM is expected to officially decide on progressing to the next stage of the joint venture before the end of the month.
As part of the agreement, Bryah has prepared a technical report and budget for OM to consider ahead of its decision to commit to further exploration.
For the next phase of exploration, Bryah has estimated a budget of $500,000, which will fund testing high-grade mineralised extensions at Brumby Creek as well as drilling new targets such as Cheval and Black Beauty.
In readiness of a positive decision, planning and permitting activities are underway to begin exploring the new prospects as soon as possible.
