Bryah Resources Ltd (ASX:BYH) has intersected further potential direct shipping grade manganese in reverse circulation (RC) drilling at the Bryah Basin Manganese joint venture project near Meekatharra in central Western Australia.
The company has received the final set of results from 95 RC holes for 1,664 metres at the Black Hill, Black Beauty and Cheval prospects.
Black Hill results
Best results from Black Hill were 4 metres from surface at 31.1% manganese, 4 metres from surface at 35% and 2 metres from surface at 36.3%.
Best drill results.
Drilling focused on testing two new manganese target areas at Black Beauty and Cheval and for extensions of mineralisation intersected at Black Hill in drilling completed in May 2020, where several holes recorded high-grade manganese.
The drilling program was fully funded by OM (Manganese) Limited (OMM) under the Bryah Basin Joint Venture Agreement with OMM parent company OM Holdings Limited (ASX:OMH), with Bryah managing the project.
Potential direct shipping grade
Drilling at Black Hill intersected potentially direct-shipping grade (>30% manganese) mineralisation in three drill holes (BHRC014, BYRC015 and BHRC018).
The latest results will enable Bryah to complete geological modelling and a mineral resource estimation for this high-grade prospect.
Drilling at Black Beauty and Cheval was more widely spaced and was designed to test areas of outcrop as well as for possible buried channel-style mineralisation.
Some encouraging manganese grade and intersection thicknesses were recorded at both locations.
The areas with the best results will need to be tested with further drilling.
A heritage survey is planned to begin later this month aimed at clearing additional areas for drilling, particularly in the Brumby Creek area.
Another program of manganese drilling is planned for the December 2020 quarter and will again be fully funded by OMM.
It is expected that this next drilling program will test some new exploration targets the joint venture has not yet had access to as well as testing for extensions of manganese mineralisation adjacent to previous good intercepts.
A trial using various geophysical techniques is planned to be completed over the Brumby Creek prospect during the December 2020 quarter with the aim of identifying the geophysical responses of high-grade manganese intersected in recent drilling.
